In a historic move to resurrect the largest dam removal project in the U.S., Oregon, California, the Yurok Tribe and the Karuk Tribe signed an agreement on Tuesday to push forward on dam removal.
<p>The two states take on the liability of the project, along with the Klamath River Renewal Corporation, the nonprofit in charge of the demolition, after the project stalled in July.</p><p>The dam removal project is essential to the tribes in the region — the Klamath River on the Oregon-California border — and will reopen hundreds of miles of river access to salmon that have been blocked for more than a century, in what is seen as one of the largest salmon restoration attempts in U.S. history. The removal would drain large reservoirs and reshape California's second-largest river.</p>
<p>The dams are not a part of the irrigation infrastructure in the region and are used only for power generation.</p><p>If U.S. regulators approve the plan, the project will remove four hydroelectric dams on the lower Klamath River. Legal challenges have stymied the plans from coming to fruition, as environmentalists and tribes had hoped demolition would start by 2022.</p><p>"The Klamath River is a centerpiece of tribal community, culture and sustenance and a national ecological treasure," California governor Gavin Newsom said in a <a href="https://www.gov.ca.gov/2020/11/17/governor-newsom-oregon-governor-brown-tribal-leaders-and-klamath-dam-owner-announce-agreement-to-advance-historic-salmon-restoration-plan/?utm_source=California+Trout+List&utm_campaign=5380e844e9-EMAIL_CAMPAIGN_Trout_Clout_Klamath_MOU&utm_medium=email&utm_term=0_cf2a51cf18-5380e844e9-232605593&mc_cid=5380e844e9&mc_eid=eeeff31369" target="_blank">statement</a> about the partnership. "With this agreement, we are closer than ever to restoring access to 400 miles of salmon habitat which will be a boon to the local economy."</p><p>In July, the project <a href="https://apnews.com/article/123f20f9e4b8948cf7d948482a8eec1d" target="_blank" rel="noopener noreferrer">was stalled</a> due to questions by Federal Energy Regulatory Commission concerning cost overruns and accidents, and if the Klamath River Renewal Corporation was in a fecund position to handle any upcoming issues.</p><p>However, the new state partnership adds an influx of $45 million to the project's $450 budget. The $45 million will be paid between Oregon, California, and the utility PacifiCorp as a contingency fund. PacifiCorp operates the dams and is owned by Berkshire Hathaway, one of billionaire Warren Buffett's companies.</p>
<p>Back in July the FERC found it necessary to keep PacifiCorp on the project as a co-licensee, although PacifiCorp was always in line to be removed from the deal, as it promised public utility commissions in Oregon and California, to better serve its ratepayers. If left on the deal as a co-licensee, by federal law PacifiCorp could end up paying itself to install fish ladders — concrete chutes in structures that fish pass through — to help the salmon migrate to spawning waters upstream.</p><p>In the new agreement, if approved by regulators, PacifiCorp would be removed as a co-licensee.</p><p>"As Yurok tribal people, it is our sacred duty to bring balance to the Klamath River," Yurok Tribe Chair Joseph James said in a <a href="http://www.klamathrenewal.org/bi-state-agreement-with-klamath-dam-owner-advances-historic-salmon-restoration-plan/?fbclid=IwAR0PixUu9UBM18PIx3FpPZOZJSo6XFNF2EZfydf1mTN7-k-j2AAO70XAN4A" target="_blank">KRRC statement</a>.</p><p>"At its heart, dam removal is about healing and restoration for the river, for the salmon, and for our people. We have never wavered from this obligation and we are pleased to see dam removal come closer to reality through this agreement. Reaching this important milestone would not be possible without the many tribal people who have dedicated their lives to restoring the river."</p>

In 1999 a cheering crowd watched as a backhoe breached a hydroelectric dam on Maine's Kennebec River. The effort to help restore native fish populations and the river's health was hailed as a success and ignited a nationwide movement that spurred 1,200 dam removals in two decades.
<p>The era of building large dams in the United States, which defined so much of the 20th century, is over. The prime spots for development were cemented decades ago, and the ensuing harm to fish and other wildlife has been well documented. Attention is <a href="https://www.nytimes.com/2020/10/13/climate/environmentalists-hydropower-dams.html" target="_blank">now focused</a> on removing obsolete dams and retrofitting existing hydroelectric dams to reduce ecological harm and increase energy efficiency.</p><p>Many other countries are in the same boat. Across Europe and North America "big dams stopped being built in developed nations because the best sites for dams were already developed, and environmental and social concerns made the costs unacceptable," found a <a href="https://www.pnas.org/content/115/47/11891" target="_blank">2018 study</a> in the <em>Proceedings of the National Academy of Sciences</em>.</p>
<p>Canada appears to be the exception to that.</p><p>Large dams are still being built across Canada, from Muskrat Falls in Labrador to the generically titled "Site C" in British Columbia, despite <a href="https://www.spglobal.com/marketintelligence/en/news-insights/latest-news-headlines/inquiry-slams-nalcor-s-c-12-7b-muskrat-falls-hydro-project-as-misguided-57533638" target="_blank">cost overruns</a>, outcry from some <a href="https://thenarwhal.ca/i-dont-see-why-anything-should-be-secret-first-nation-rejected-28-million-in-site-c-dam-deal-court-docs-reveal/" target="_blank" rel="noopener noreferrer">First Nations</a> and even <a href="https://thetyee.ca/News/2017/03/13/UN-Calls-for-Site-C-Review/" target="_blank" rel="noopener noreferrer">environmental concerns</a> from the United Nations.</p><p>Hydroelectric power already supplies 60% of the country's energy. But the dam building isn't just to feed Canada's power needs. It's also become a hot export commodity.</p><p>As U.S. states look to meet new clean energy targets, imported low-carbon hydropower from across the northern border has become a larger part of the conversation — and the grid. New England already gets 17% of its energy from Canadian hydropower, Midwest states around 12% and New York 5%.</p><p>That number is likely to jump.</p><p>A new transmission project to bring 250 megawatts of Canadian hydropower to the United States <a href="https://renewablesnow.com/news/minnesota-power-brings-online-250-mw-hydro-wind-transmission-line-702303/" target="_blank" rel="noopener noreferrer">just came online in Minnesota</a>. Two more are in the works for Massachusetts and New York.</p>
<p>Proponents say we need large-scale hydro to grease the wheels of the clean energy transition. Others caution that it comes with a larger environmental cost compared to wind and solar and could open the floodgates for more dam building.</p><p>There's one shared bit of common ground, though: We need to act quickly and wisely to tackle the climate crisis.</p><p>"This is the decade for getting 50% of the way there on renewables, but also proving out the pathway to get to net-zero by mid-century, if not before," says Peter Rothstein, president of the <a href="https://www.necec.org/" target="_blank">Northeast Clean Energy Council</a>.</p><p>How hydro figures into that process is still a complicated issue.</p>
<h3>Clean Energy Demand Surges</h3><p>The Northeast is one place where the energy transition is off and running.</p><p>All six New England states have pledged to cut greenhouse gas emissions 80% over 1990 levels by 2050, and some are aiming higher.</p><p>Neighboring New York is also keeping pace. Last year the Empire State committed to achieving an 85% reduction in greenhouse gas emissions by 2050 and 70% renewable electricity by 2030.</p><p>How will those goals be achieved?</p><p>For some, imported Canadian hydropower looks poised to play a big role, and two new projects appear close to breaking ground.</p>

<p><a href="https://chpexpress.com/" target="_blank" rel="noopener noreferrer">Champlain Hudson Power Express</a>, a 330-mile-long transmission line, would deliver 1,000 megawatts of hydropower from Quebec to the New York metro area and could supply about a million homes — helping to reduce dependence on fossil fuels.</p><p>The project — a joint venture of the province-run Hydro-Québec and Transmission Developers Inc., a subsidiary of the private equity firm Blackstone Group — has already received the necessary permits for construction, but no contracts for the power have been signed.</p><p>Construction, however, could still start next year, with the project scheduled to come online in 2025.</p><p>Massachusetts has an even bigger project in the works. <a href="https://www.necleanenergyconnect.org/project-overview" target="_blank">New England Clean Energy Connect</a> would bring 1,500 megawatts of capacity through a 145-mile-long transmission line running through Maine from Canada to Massachusetts. It too would come from Hydro-Québec, this time working in conjunction with Central Maine Power.</p><p>The project, which is projected to cut greenhouse gas emissions by 3 million tons a year in New England, has received its necessary permits from the state of Maine but still awaits federal permits from the Department of Energy and the Army Corps of Engineers.</p><p>Opposition groups, including some environmental organizations, are also <a href="https://www.nrcm.org/programs/climate/proposed-cmp-transmission-line-bad-deal-maine/" target="_blank" rel="noopener noreferrer">challenging various aspects of the project</a> in court. And a coalition of First Nations communities that have seen dams built on their ancestral lands have voiced their opposition. (You can read more about that transmission line in <a href="https://therevelator.org/hydropower-necec/" target="_blank" rel="noopener noreferrer">Part I of this series</a>.)</p><p>More could be on the way. Nalcor Energy — the province-run hydro company of Newfoundland and Labrador — is nearing completion on its 824-megawatt <a href="https://muskratfalls.nalcorenergy.com/" target="_blank" rel="noopener noreferrer">Muskrat Falls hydro project</a> on the Churchill (or Grand) River. Costs have just <a href="https://www.thechronicleherald.ca/business/regional-business/muskrat-falls-costs-top-131-billion-503057/" target="_blank" rel="noopener noreferrer">surpassed $13 billion</a> — twice what was first estimated.</p><p>Some of the energy is already slated to be sent to other parts of Canada and then — hopefully, <a href="https://muskratfalls.nalcorenergy.com/project-overview/" target="_blank" rel="noopener noreferrer">according to Nalcor</a> — to New England.</p>
<h3>Environmental Considerations</h3><p>What's the net impact of these planned projects? That's hard to say. Tallying the environmental benefit or harm from large-scale hydro is complicated.</p><p>One of the biggest metrics of assessing environmental impact is greenhouse gas emissions.</p><p>The first phase of emissions comes just from building its infrastructure. Large-scale hydropower involves the construction of generating stations, and often accompanying dams and reservoirs. And then there are hundreds of miles of transmission lines that need to be constructed to move that power.</p><p>What comes next, once a project comes online, depends on multiple factors. Research has shown that hydropower emissions vary widely based on the location, climate and area of land flooded. Hydro emissions are also highest when a reservoir is first flooded and then decrease in the following years.</p><p>All told, over the life cycle of a project, most hydropower is cleaner than fossil fuels, although not always as clean as wind and solar. A <a href="https://www.nature.com/articles/s41560-017-0032-9" target="_blank" rel="noopener noreferrer">study</a> in <em>Nature Energy</em> on the projected life-cycle emissions of energy sources put solar at 6 grams of CO2 equivalent per kilowatt hour and wind at 4. The researchers estimated typical hydro at 97, but there's great variation between sites.</p><p>A 2014 <a href="https://www.hydroquebec.com/data/developpement-durable/pdf/comparing-power-generation-options-and-electricity-mixes.pdf" target="_blank" rel="noopener noreferrer">report</a> prepared by the research group CIRAIG on behalf of Hydro-Québec found the average life-cycle emissions of the company's fleet of 62 generation stations was between 6 and 17 grams of CO2 equivalent per kilowatt hour.</p><p>Alain Tremblay, Hydro-Québec's lead scientist on greenhouse gas emissions, says tracking from their most recent complex of dams on the Romaine River shows emissions between 5 and 10 grams of CO2 equivalent per kilowatt hour.</p>
<p>There are other environmental considerations beyond greenhouse gas emissions.</p><p>The nonprofit Natural Resources Council of Maine opposes the New England Clean Energy Connect, in part out of concern about fragmented habitat and critical wildlife populations, including brook trout. The transmission line would require clearing a 53-mile stretch of forest through the North Maine Woods.</p><p>In New York the nonprofit <a href="https://www.riverkeeper.org/" target="_blank">Riverkeeper</a> reversed its earlier support for the Champlain Hudson Power Express and has now <a href="https://www.riverkeeper.org/news-events/news/energy/riverkeeper-statement-regarding-the-champlain-hudson-power-express/" target="_blank" rel="noopener noreferrer">come out against that project</a>, which would send its electrical cable down the length of the Hudson River.</p><p>"This sets a precedent that the Hudson is a conduit for extension cords from Canada or from anywhere," says John Lipscomb, Riverkeeper's vice president of advocacy. "It should be off limits to that kind of thing."</p><p>The Hudson contains legacy pollution from polychlorinated biphenyls (PCBs) dumped decades ago and other contaminants that could be turned up as the cable is dug in the riverbed. Over the years some of that pollution has been remediated, but not all. And plans to avoid putting cable in the areas of the worst-known contamination aren't sufficient to protect the ecosystem, he says.</p>

<p>There's also concern that imperiled fish species, like endangered shortnose sturgeon and Atlantic sturgeon, could be harmed by the electrical cable. The river was designated as critical habitat for Atlantic sturgeon, but no <a href="https://biologicaldiversity.org/w/news/press-releases/regulators-warned-of-champlain-hudson-power-express-projects-environmental-impact-2020-10-08/" target="_blank">Endangered Species Act review</a> has been initiated to assess if the cable could threaten fish populations.</p><p>"Both of these fishes have nervous systems similar to that of sharks, which are incredibly sensitive to electric signals," says Roger Downs, conservation director of the Sierra Club Atlantic Chapter. "It's a huge experiment to suddenly put an electrical signal down the backbone of this river."</p><p>Lipscomb shares this concern. After all the work that's been done in recent years to help restore the Hudson and its estuary, he says "it's heartbreaking that we still think of this river as a resource."</p><p>Hydropower may be renewable, he says, but from an environmental perspective it isn't sustainable. "Unless a river's value is zero," he says. "If a river has any value as an ecosystem, as a host for life, then hydropower isn't even a consideration."</p>
<h3>Upstream Justice Concerns</h3><p>In 1990 a group of Cree and Inuit protestors paddled the Hudson River to Manhattan to ask New Yorkers to <a href="https://www.cbc.ca/radio/asithappens/as-it-happens-wednesday-edition-1.3044034/commemorating-25th-anniversary-of-historic-odeyak-voyage-1.3044498" target="_blank" rel="noopener noreferrer">oppose a power purchase</a> agreement between the state and Quebec and the construction of a second dam in the James Bay hydroelectric project in northern Quebec.</p><p>They were successful. Now, 30 years later, a different group of First Nations is making a similar plea.</p><p>On October 7 the First Nations of Pessamit, Wemotaci, Pikogan, Lac Simon and Kitcisakik sent a letter to the U.S. Department of Energy stating their opposition to the Massachusetts transmission line. The groups wrote that one-third of Hydro-Québec's installed power is "produced in our respective ancestral territories from reservoirs, dams, power plants and various other installations, without prior consultation, without our consent and without compensation."</p><p>Over the decades of hydropower buildout in Canada many First Nations communities — but not all — have been consulted on projects and struck agreements with power companies.</p><p>Major hydroelectric projects have altered the flow of rivers and in some cases, the food and cultural resources used by Indigenous communities.</p><p>There are also health concerns.</p><p>A 2016 <a href="https://pubs.acs.org/doi/full/10.1021/acs.est.6b04447" target="_blank" rel="noopener noreferrer">study</a> by Harvard University researchers, published in <em>Environmental Science and Technology,</em> found that flooding reservoirs for hydroelectric projects in Canada would increase the risk of mercury poisoning in Indigenous communities at 90% of the dam sites.</p><p>When land is flooded for a reservoir, the microbes in the soil convert naturally occurring mercury into more dangerous methylmercury, which then works its way up the food chain. That puts anyone who relies on local wildlife such as fish, birds and seals at risk. In the northern reaches of Canada, that's largely Indigenous people.</p><p>The researchers looked at how three Inuit communities downstream of Nalcor's Muskrat Falls project would fare. And they found that, on average, risk of exposure for community members would double after the area was flooded. That could translate to higher risks for cardiovascular disease and neurodevelopmental delays for children.</p><p>The more people rely on local food sources, the more harm they're exposed to. And in this remote region where store-bought food is very expensive, that's a serious concern.</p>

<p>"People have a very high prevalence of economic insecurity and that translates into insecure access to Western foods at the grocery store," says Ryan Calder, a co-author of the study and now an assistant professor of environmental health and policy at Virginia Tech. "Traditional food systems account for a smaller and smaller fraction of overall calories, but a wildly disproportionate fraction of nutrient intake."</p><p>Despite this, he doesn't think their research should be taken as a commentary on whether hydroelectric power itself is good or bad. "We really just criticized [the company's] risk assessment," he says.</p><p>Earlier studies by Nalcor claimed the effect on the Inuit would be negligible as the mercury would quickly dilute in downstream waters.</p><p>"They had no basis for saying there was going to be no impact," says Calder. "It was clear that they were trying to ignore their obligations — if not legal, then certainly moral — to Indigenous people."</p><p>The researchers also found that about half of the other sites they studied would have equal or greater concentrations of methylmercury than Muskrat Falls.</p><p>Roberta Frampton Benefiel of <a href="http://www.grandriverkeeperlabrador.ca/" target="_blank">Grand Riverkeeper Labrador</a>, who lives near the Muskrat Falls project, says she wasn't surprised by Nalcor's position. "Aboriginal people don't count to this government and so we have to make the Aboriginal people count," she says.</p><p>She has spoken to environmental organizations in the United States to help raise awareness about some of the local effects of dam development in Canada.</p><p>"I want people in the United States to understand that when they flip their light switch, if they accept these power lines from Canada, they're poisoning northern communities," she says.</p>
<h3>More Dams?</h3><p>New York and Massachusetts have been eager for hydropower from Canada as long as it doesn't mean the construction of new dams for the transmission projects.</p><p>Hydro-Québec says it has enough reserves for export to New York and Massachusetts without redirecting power from its existing United States or Canadian customers.</p><p>It's nearly finished with the last dam in the complex of four generating stations on the Romaine River, which along with other projects, has added 5,000 megawatts of capacity over the last decade. Although it does has the <a href="https://www.nerc.com/pa/RAPA/ra/Reliability%20Assessments%20DL/NERC_LTRA_2019.pdf" target="_blank" rel="noopener noreferrer">lowest reserve margin</a> of utilities in the region, according to the North American Electric Reliability Corporation's 2019 assessment.</p><p>In previous years Hydro-Québec did preliminary work to explore the possibility of new dams on the Little Mécatina River, but company spokesperson Lynn St-Laurent says they currently have no plans for new dams and that project is no longer in their strategic plan.</p><p>Gary Sutherland, director of strategic affairs for northeast markets at Hydro-Québec, says that additional energy demand for export could be met with increased energy efficiency in Quebec and more wind projects. Quebec Premier François Legault <a href="https://twitter.com/francoislegault/status/1316155854610001920" target="_blank" rel="noopener noreferrer">tweeted last week</a> that the province's next addition of capacity, if needed, would be the 200-megawatt <a href="https://energycentral.com/news/quebec-interest-wind-power-projects-back-horizon" target="_blank" rel="noopener noreferrer">Apuiat wind farm</a>.</p><p>Elsewhere in Canada, however, dam building continues.</p><p>Manitoba Hydro and four First Nations are in the process of building the <a href="https://www.enr.com/articles/45695-mega-canadian-hydro-project-moves-forward-despite-surprises-bitter-cold" target="_blank" rel="noopener noreferrer">Keeyask project</a>, a 695-megawatt hydroelectric generating station on the Nelson River.</p><p>British Columbia also continues to muddle along on development at Site C, a 1,100-megawatt dam on the Peace River that has faced mounting problems and protests.</p>

<p>This includes, according to a report in <em><a href="https://thenarwhal.ca/topics/site-c-dam-bc/" target="_blank" rel="noopener noreferrer">The Narwhal</a></em>, legal challenges from "landowners and First Nations who oppose flooding 128 kilometers of the Peace River and its tributaries, putting Indigenous burial grounds, traditional hunting and fishing areas, habitat for more than 100 species vulnerable to extinction and some of Canada's richest farmland under up to 50 meters of water."</p><p>Construction has also <a href="https://vancouversun.com/business/site-c-still-scaling-up-construction-to-meet-important-milestone-while-remains-up-in-the-air" target="_blank" rel="noopener noreferrer">uncovered geological issues</a> that could make parts of the foundation unstable, prompting <a href="https://www.cbc.ca/news/canada/british-columbia/site-c-letter-1.5741443" target="_blank" rel="noopener noreferrer">numerous calls</a> to stop development.</p><p><a href="https://1694d3a6-ec13-42ea-a8f0-a29cda354660.usrfiles.com/ugd/1694d3_b5baab11560f4bf4a3910e992c608509.pdf" target="_blank" rel="noopener noreferrer">New research</a> by energy analyst Robert McCullough, who runs a Portland, <a href="https://www.mresearch.com/" target="_blank" rel="noopener noreferrer">Oregon-based consulting firm</a>, found that if the project continues its likely to have surplus energy that will need to be sold outside the province at a loss to ratepayers.</p><p>But a poor financial outlook doesn't always mean the end of dam projects in Canada.</p><p>In Labrador Nalcor also has another large project planned — the 2,250-megawatt Gull Island dam, farther upstream from Muskrat Falls, which could be built if there's a buyer for the power.</p><p>It's a prospect Benefiel finds shocking, considering the company's most recent project was so over budget that it prompted a provincial <a href="https://www.muskratfallsinquiry.ca/" target="_blank">Commission of Inquiry</a>, which found that Muskrat Falls put the financial health of the entire province at risk.</p>
<h3>Is Hydro Needed?</h3><p>Considering all the complexities of hydro projects and the related transmission infrastructure, is it necessary to move U.S. states off fossil fuels and toward clean energy goals?</p><p>That depends on who you talk to.</p><p>Despite investment in wind and solar, "hydro has a couple of things going for it," says Rothstein of the Northeast Clean Energy Council. The first is that it's able to compete on costs, and second is the "dispatchability."</p><p>Thanks to decades of dam building, Canadian hydropower is ready to go — pending transmission capacity. It's also seen as less variable than wind and solar, although hydropower does fluctuate by season and by year, depending on precipitation.</p><p>"I think hydro will play a role, but it's not going to be the only resource," says Rothstein. Offshore wind holds the biggest potential for large-scale projects in the region, he says.</p><p>New York has already awarded contracts to procure <a href="https://www.utilitydive.com/news/new-york-awards-record-1700-mw-offshore-wind-contracts/559091/" target="_blank" rel="noopener noreferrer">1,700 megawatts of offshore wind</a> and in July <a href="https://renewablesnow.com/news/new-york-opens-procurement-round-for-4-gw-of-renewables-707197/" target="_blank" rel="noopener noreferrer">put out a call</a> to solicit another 2,500 megawatts of offshore wind and 1,500 megawatts of land-based, large-scale renewables.</p><p>Massachusetts is making strides toward wind energy, too. In 2016 Gov.

Like many other plant-based foods and products, CBD oil is one dietary supplement where "organic" labels are very important to consumers. However, there are little to no regulations within the hemp industry when it comes to deeming a product as organic, which makes it increasingly difficult for shoppers to find the best CBD oil products available on the market.
<p>Here you can learn about the importance of organic hemp oil, why it's better for the environment, and which CBD companies actually make trustworthy products with sustainable farming processes. origins which weigh heavily on many consumers who want to buy a product that's produced in the best way possible for not only themselves to ingest, but for the environment as well through sustainable farming methods. </p><h2>What Is CBD Oil?</h2><p>First things first, CBD stands for cannabidiol, and it's a cannabinoid found within cannabis sativa plants. This plant compound is believed to have many potential benefits, and it is primarily derived from hemp plants via a CO2 extraction process. </p><p>Since CBD is extracted from industrial hemp, which contains only trace amounts of THC (the psychoactive component in cannabis plants), this means that CBD won't make you feel high like marijuana, which has much higher levels of THC that causes psychoactive effects. Instead, the effects of CBD are much more subtle and promote a general sense of calm and relaxation in most users.</p><h2>What Makes a CBD Oil Organic?</h2><p>In terms of organic labels, perhaps the most important (and prominent) certification comes from the United States Department of Agriculture (USDA). This government organization has been labeling foods as "organic" for many years, but what exactly does this certification entail? Essentially, a label indicating that a product is "USDA Organic" or "Certified Organic" means that at least 95% of the ingredients are obtained from organic sources.</p><p>For a crop to be considered organic by the USDA, it must be grown without the use of industrial solvents, irradiation, genetic engineering (GMOs), synthetic pesticides, or chemical fertilizer. Instead, farmers rely on natural substances and <a href="https://www.usda.gov/media/blog/2012/03/22/organic-101-what-usda-organic-label-means" rel="noopener noreferrer" target="_blank">mechanical, physical, or biologically based farming</a> techniques to cultivate healthy and organic crops.</p><p>Before the passage of the 2018 Farm Bill, no hemp-derived products could be dubbed as "certified organic" since the hemp plant and its extracts were still categorized as a Schedule I Controlled Substance. However, it's still difficult for CBD companies to obtain a USDA certified organic label for their products due to the legal grey area that still surrounds CBD extracts. </p><p>Because of these challenges, and due to the fact that industrial hemp has only recently become an agricultural crop, very few CBD oils are USDA certified organic. Rather, many CBD products contain hemp extracts from plants that were grown in organic conditions but may not be federally certified.</p><h2>What are the Best Organic CBD Oil Brands?</h2><p><em>Each product featured here has been independently selected by the writer. If you make a purchase using the links included, we may earn commission.</em></p><em><br></em>
<h2>Why Organic Hemp Oil Matters</h2><p>Hemp is a unique plant, not only for its rich cannabinoid content, but also for its ability to absorb a wide variety of components in soil. But this trait poses great risks when it comes to the creation of CBD products derived from hemp.</p><p>Because hemp has a high capacity for compound uptake, this means that the plants can retain <a href="https://www.remedyreview.com/industry/lab-test-results/" target="_blank">harmful chemicals like pesticides</a>, heavy metals, and other residual solvents. This is especially true when it comes to synthetic chemicals that are more toxic to humans, and difficult to remove once they have been absorbed by the hemp plant.</p><p>Organic farming practices help reduce the risk of hemp crops absorbing harsh chemicals that may later end up in CBD oil after extraction. When you're taking CBD as a wellness supplement to help alleviate your symptoms or improve your overall well-being, the last thing you want is to ingest compounds that might negatively outweigh the benefits of CBD. This is an important reason to look for third party lab test results when shopping for CBD products since these certificates of analysis can show the full cannabinoid and terpene profile of a hemp extract, as well as test results that search for the presence of any residual solvents.</p><p>In addition to creating a better end product, organic farming practices are also better for the environment. Sustainable and organic farming methods may <a href="https://www.helpguide.org/articles/healthy-eating/organic-foods.htm" rel="noopener noreferrer" target="_blank">reduce pollution, conserve water, reduce soil erosion, increase soil fertility, and use less energy</a>. The use of natural pest deterrents as opposed to chemical pesticides is also better for nearby animal populations and ecosystems.</p><h3>Organic vs. Natural</h3><p>While there are only a select few companies offering certified organic ingredients in their products, almost every brand in the CBD market creates "natural" products. The term "all-natural" or "plant-based" does not mean that a product is organic, and since hemp oil is a natural derivative of hemp plants, these products are often referred to as all-natural. However, there are some synthetic CBD oils that should be avoided because they are chemically constructed and may produce unwanted side effects that are not caused by naturally derived CBD extracts.</p><h2>What are the Benefits of Organic CBD Oil?</h2><p>There's a long list of potential CBD oil health benefits, and some of the most common wellness advantages include:</p><ul class="ee-ul"><li><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2503660/" target="_blank">Chronic pain relief</a></li><li><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4604171/" target="_blank">Anti-anxiety effects</a></li><li>Better sleep</li><li><a href="https://www.psychologytoday.com/us/blog/inner-source/201901/cbd-oil-mental-health-should-you-take-it-too" rel="noopener noreferrer" target="_blank">Improvements in mood</a></li><li>Internal balance and regulation</li></ul><p>When dealing with pain, inflammation, sleep issues, and mental health struggles, it can be hard to find sufficient treatment options. The use of certain prescriptions can cause unwanted side effects, yet they are often the only solution for patients with these medical conditions. In search of other therapies, people have started to flock towards CBD oil as an alternative remedy for a variety of conditions. However, it should be noted that CBD products are not approved by the Food and Drug Administration (FDA), and you should seek your doctor's advice before using CBD if you have a serious medical condition.</p><h2>Look at the Labels Before You Buy CBD Oil</h2><p>When you go online to buy CBD oil, you'll quickly realize there is an overwhelming number of brands that are saturating the market. It can be difficult to determine which products are truly as good as they make themselves out to be. Always look for up-to-date third-party lab tests so you know you are getting a great product, and don't hesitate to contact the brand if you have any additional questions. And if you're intent on purchasing 100% organic CBD oil, it's best to look for certified products or brands that are held to strict regulatory standards.</p><p><strong>Melena Gurganus </strong>is the Reviews Editor at EcoWatch.

Heating with coal, oil and natural gas accounts for around a quarter of global greenhouse gas emissions. But that's something we can change, says Wolfgang Feist, founder of the Passive House Institute in the western German city of Darmstadt.
<p>"Buildings can be powered in a <a href="https://www.ecowatch.com/tag/climate-change">climate</a>-neutral way, and that's possible worldwide with <a href="http://www.ecowatch.com/renewable-energy/">renewable energies</a>," he told DW, adding that a crucial factor is to <a href="https://www.dw.com/en/an-energy-efficient-house-in-south-tyrol/a-19300267" target="_blank">make buildings more efficient</a> so no energy is wasted.</p><p>"With good insulation and ventilation systems, it's possible to achieve energy savings — compared to conventional buildings — of 80-90% in new buildings and 75-80% through energy-efficient renovation in old buildings."</p><p>The remaining demand could then be met with a mix of renewable energies. And this combination can vary, depending on the region, says Feist, who is a professor of physics and a pioneer of efficient construction methods.</p><p>"I see district heating with renewable energies, and heating with ambient heat and heat pumps as important sources here," he says.</p><p>The use of wood or wooden pellets is another way of meeting the heating needs of individual buildings, Feist says, adding however that this is "not a sensible option" for entire cities or industries because it's not sustainable and would create excessive demand for biomass.</p>

Germany's financial capital has big environmental plans.
<h3>Frankfurt Strives for Climate Neutrality</h3><p>The German city of <a href="https://www.dw.com/en/frankfurt-shoots-for-100-percent-renewables/a-36467796" target="_blank">Frankfurt is aiming to become climate neutral by 2050</a>. In order to reach that goal, the financial hub is relying on a range of technologies, says Paul Fay from the city's energy department, who is coordinating the transition. With help from scientists, the city has drawn up a master plan that includes passive houses and energy-efficient refurbishments on older structures.</p><p><a href="http://www.ecowatch.com/tag/solar">Solar</a> panels on the roofs of Frankfurt's buildings will generate some of the city's thermal energy. Another share will come from heating pipelines serving the city's districts, where warmth will be created by burning waste and wood, or through waste heat from data centers. Ambient energy from the ground can also be harnessed with the help of heat pumps.</p>
<h3>How Does a Heat Pump Work?</h3><p>In theory, a heat pump works like a refrigerator — within a closed, multistage system, heat is generated in a compressor, while cool air is created in an evaporator.</p><p>A liquid coolant extracts heat from the environment to warm buildings or water. The heat pump takes energy from the ground, groundwater or air.</p>
<img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjYwMTY5Mi9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTY3Njg5MTUxNn0.zX_8j-z2KN-p9mvcP64ZBD070K1DF3qJsuve0uykd3o/img.png?width=980" id="94cb6" class="rm-shortcode" data-rm-shortcode-id="753c820969e050d363c853309c63346e" data-rm-shortcode-name="rebelmouse-image" />
<p><br>Heat pumps need electricity as their operating energy, and how well they perform depends mainly on the heat source.</p><p>"We examined 60 heat pump systems in older buildings in Germany," says Marek Miara, a researcher at the <a href="https://www.ise.fraunhofer.de/en.html" target="_blank">Fraunhofer Institute for Solar Energy Systems (ISE)</a> in Freiburg.</p><p>"Heat pumps in older buildings that use air as a heat source generate an average of around 3 kilowatt-hours of heat from 1 kilowatt of electricity. And heat pumps using groundwater and soil as heat sources generate on average 3.9 times as much heat," Miara told DW, adding that systems in new buildings are generally more efficient.</p>
<h3>Growth in Key Technologies</h3><p>Heat pumps are a core component of plans for climate-neutral energy and heating in the future, and the technology is increasingly replacing <a href="https://www.ecowatch.com/tag/fossil-fuels">fossil fuel</a>-powered heating systems around the world.</p><p>"We're seeing a very positive global trend," says Thomas Nowak from the lobby organization the <a href="https://www.ehpa.org/" target="_blank">European Heat Pump Association (EHPA)</a>. "We're experiencing a golden age for heat pumps, it's becoming a mass market."</p>
<img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjYwMTcwNy9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTY0ODA0NjA2Nn0.fRLQAAvNex-Sa82ahSWDxLEpoDlBQHKNkzxENQ97zz8/img.png?width=980" id="6992a" class="rm-shortcode" data-rm-shortcode-id="6ee997b71226136793c1b2380791fb70" data-rm-shortcode-name="rebelmouse-image" />
<p>According to an <a href="https://heatroadmap.eu/roadmaps/" target="_blank">EHPA report</a>, 18 million heat pumps were sold worldwide in 2018 — 1.3 million of them in Europe. Global sales are growing by 10% each year, the report said.</p>
<h3>Heating With Less CO2</h3><p>Heat pumps have proven extremely popular in Europe, especially in Scandinavian nations. Electricity in these countries is already generated mainly by climate-friendly <a href="http://www.ecowatch.com/tag/wind">wind</a> and <a href="https://www.ecowatch.com/tag/hydropower">hydropower</a>. According to calculations by Fraunhofer ISE, heat pump systems in Sweden generate 90% fewer carbon emissions than heating systems that rely on natural gas.</p><p>Many countries in the European Union and other parts of the world still get much of their electricity from coal and gas. But according to calculations by Fraunhofer researchers, heat pumps there would also be a more environmentally friendly option than heating with natural gas. Across the EU, using heat pumps would result in an average CO2 saving of around 60% compared to natural gas. In Germany, the saving would be around 30%, the Fraunhofer researchers say.</p><p>If electricity continues to become more climate friendly through the expansion of wind and solar power, as is currently the case in Germany, CO2 savings from heat pump systems will only keep growing. And if the pumps' operating power comes from 100% renewables, then this heating technology becomes climate neutral.</p>
<h3>Heating Transformation Needs Policy</h3><p>Energy and building experts agree that making the switch to climate-neutral heating in all buildings and industries worldwide is certainly possible.</p>
<img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yMjYwMTcxMC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYyOTUxNjQxN30.qizn5NtyemgOsOZTJZUSdOaxfP0XhZet5ARQymtWkbs/img.jpg?width=980" id="e085b" class="rm-shortcode" data-rm-shortcode-id="9490f7d62be99ccc01195b37b0593e27" data-rm-shortcode-name="rebelmouse-image" />
The Swiss city of Schaffhausen is among the growing number of municipalities using heat pump technology.

Experts and environmentalists are calling for a ban on the installation of new polluting heating systems.
<p>"However, there is still a need for more training," says Andreas Nordhoff, a consultant for passive house technology who also trains people in the construction industry. "Craftsmen, architects and building owners often lack knowledge about how everything can be optimally coordinated, and how much energy and money can be saved," he says.</p><p>Politics also has an important role to play in establishing a climate-friendly heat supply.</p><p>"What we need now is a ban on new oil heating systems. These are particularly harmful to the climate, so new installations should be prohibited from now on," says Nicolas Besser, project manager for energy and climate protection at the <a href="https://www.duh.de/englisch/" target="_blank">German environmental organization Deutsche Umwelthilfe (DUH)</a>.</p><p>"Natural gas heating systems are more climate friendly compared to oil heating, but they're still harmful. That's why we also need a ban on installing them from 2025," Besser says.</p><p>In order to reach climate targets set out in the <a href="https://www.ecowatch.com/tag/paris-agreement">Paris agreement</a>, DUH is calling for an emergency climate protection program for buildings. They want to see funding put towards renovating structures, expanding municipal heating networks and accelerating the phaseout of oil and gas heating.</p>

Native American tribes oppose a plan to build dams on the Little Colorado River (right side) upstream of Grand Canyon National Park. National Parks Service
A proposal to dam four parts of a Colorado River tributary for hydropower has drawn significant opposition from Native American tribes, environmentalists and regulatory agencies, according to the AP.
<p>Opponents of the project claim that the four <a href="http://www.ecowatch.com/tag/dams" target="_self">dams</a> would severely alter water flows in the main Colorado River in parts that run through Grand Canyon National Park and it would affect the fishery there, according to a press release from the advocacy group <a href="https://www.nationalparkstraveler.org/2019/11/conservationists-oppose-plan-build-dams-little-colorado-river-upstream-grand-canyon" target="_blank">National Parks Traveler</a>.</p><p>Phoenix-based Pumped Hydro Storage asked the Federal Energy Regulatory Commission for preliminary permits to study the feasibility of damming the Little Colorado River, just east of Grand Canyon National Park. All four dams are squarely within the Navajo Nation's land. The company's manager, Steve Irwin, said the projects offer economic benefits to the area, including paved roads, tourism and jobs, as the <a href="https://apnews.com/4437ead4afb64bda8671e20ab7d471cf" target="_blank">AP</a> reported.</p>

Renewable sources of electricity are set for rapid growth over the next five years, which could see them match the output of the world's coal-fired power stations for the first time ever.
<p><br/></p>
<p>This would mean renewables matching <a href="http://www.ecowatch.com/tag/coal">coal</a> as the joint-largest contributors to the global electricity mix in 2024, according to Carbon Brief analysis of new forecasts in the International Energy Agency (IEA) Renewables 2019 report.</p><p>The analysis is based on the IEA's "accelerated case," in which the combined capacity of <a href="https://www.ecowatch.com/tag/hydropower">hydro</a>, <a href="http://www.ecowatch.com/tag/wind">wind</a>, <a href="http://www.ecowatch.com/tag/solar">solar</a> and biomass increases by more than 60% over the next five years. Even in its "base case," renewable capacity is set to expand by nearly 50%, the IEA forecasts.</p><p>Dr. Fatih Birol, IEA executive director, writes in a foreword to the report that "thanks to falling costs, technologies such as solar photovoltaics (PV) and wind are at the heart of transformations taking place across the global energy system." He adds: "Their increasing deployment is crucial for efforts to tackle greenhouse gas emissions, reduce air pollution and expand energy access."</p><p>The IEA's base-case renewable forecasts have historically underestimated the pace of growth. Yet even in its accelerated case, the extra electricity from renewable sources will fail to keep up with rising overall demand, the IEA forecasts suggest.</p><p>This means that generation from <a href="https://www.ecowatch.com/tag/fossil-fuels">fossil fuels</a> would also have to increase, along with the electricity sector's CO2 emissions, rather than falling rapidly as required to meet global climate goals.</p>
<h4>Rapid Growth</h4><p>In its base case, the newly published 2019 IEA report forecasts that global renewable energy capacity will increase by close to 50% in the five years to 2024, as the chart below shows (red line).</p><p>This would mean global hydro, wind, solar and biomass capacity rising from 2,501 gigawatts (GW) in 2018 to 3,721GW in 2024. The increase of 1,220GW means the world would be building renewable capacity equal to the entire <a href="https://www.carbonbrief.org/mapped-how-the-us-generates-electricity" target="_blank">U.S. electricity system</a> today, says the IEA.</p>

<p>Within the base case total, wind and solar capacity would nearly double, contributing around 85% of the increase for all renewables, with hydro accounting for another tenth and bioenergy 4%.</p><p>It is worth noting, however, that the IEA's base-case has historically underestimated the pace of growth, as the chart above shows. As a result, successive forecasts have been revised upwards in light of increasingly favorable policy conditions and faster-than-expected reductions in cost.</p><p>In a series of auctions tracked by the IEA, the cost of solar has fallen from $160 per megawatt hour (MWh) in 2014 to an average of $17/MWh for projects due to start operating in 2023, while for onshore wind the costs have fallen from $65/MWh in 2014 to $30/MWh for 2023.</p><p>The IEA has also included an "accelerated case" in its 2019 forecasts, shown with a dashed line in the chart, above. In this case, renewable capacity would increase by more than 60% to 4,036GW in 2024, adding 1,535GW in five years, equivalent to the current total fleets of the U.S. and Japan.</p><p>This is not the first time that the IEA has hedged its view for the next five years.</p><p><a href="https://www.carbonbrief.org/analysis-how-have-iea-renewable-forecasts-changed" target="_blank">Back in 2016</a>, for example, the agency's base case forecast some 826GW of renewable capacity being added by 2021, with an accelerated case adding 1,061GW. This accelerated case from 2016 aligns closely with the 2019 base case, which has 1,096GW being added during 2016-2021.</p><h4>Bottom Up</h4><p>The IEA forecast is based on detailed bottom-up analysis of the market, policy and electricity system outlook in each of 41 individual countries and every world region.</p><p>Capacity growth is expected to be concentrated in just a handful of regions, the IEA says, with 40% in China, 17% in Europe, 11% in the U.S. and 9% in India. Together, these account for four-fifths of the global increase in the IEA's base case.</p><p>As already mentioned, renewable capacity has consistently oustripped the growth expected in the IEA base case, which has tended to suggest that annual additions will remain at a similar level into the future, rather than consistently rising year on year.</p><p>The amount of new renewable capacity built around the world, each year since 2006, is shown in red in the chart below, while successive base-case forecasts are shown in shades of blue.</p>

<p>As in previous years, the IEA has once again raised its forecast growth over the next five years, adding 14% to the amount of new capacity that it expects to be built. Last year, it <a href="https://www.carbonbrief.org/iea-bioenergy-lead-growth-renewables-over-next-five-years" target="_blank">forecast growth</a> of 1,070GW over the five years to 2023. Now, it is forecasting 1,220GW in the five years to 2024.</p><p>Responding to a question from Carbon Brief, Heymi Bahar, IEA senior renewable energy analyst and a lead author of the report told a pre-publication press call that this upwards revision was due to a roughly 50/50 combination of more favorable policy and lower costs.</p><p>On the policy side, Bahar pointed to a series of additional renewables auctions in the EU, initiated as countries look to meet <a href="https://www.carbonbrief.org/whos-hitting-the-eus-2020-renewables-target-and-whos-holding-it-back" target="_blank">their 2020 targets</a> and as the bloc's <a href="https://ec.europa.eu/clima/policies/strategies/2030_en" target="_blank">2030 goals</a> have been firmed up. In China, grid expansion and market reforms have reduced the amount of renewable electricity that is "curtailed" – generation that is wasted due to insufficient grid capacity or an excess of supply.</p><p>The flattening of renewable capacity growth during 2018, seen in the red line in the chart, above, was also largely down to changes in China. This stalling marked the <a href="https://www.iea.org/newsroom/news/2019/may/renewable-capacity-growth-worldwide-stalled-in-2018-after-two-decades-of-strong-e.html" target="_blank">first time in two decades</a> when the amount of renewable capacity built each year failed to exceed that seen before.</p><p>During 2018, China started to <a href="https://www.carbonbrief.org/solar-now-cheaper-than-grid-electricity-in-every-chinese-city-study-finds" target="_blank">shift decisively</a> away from support based on "feed-in tariffs" that pay renewables a fixed price for each unit of electricity generated and towards a system of competitive auctions awarding a fixed pot of money or capacity to the lowest bidders.</p><p>This seismic change in the policy landscape of the world's largest market for renewable energy had been widely expected to dent global growth, including in <a href="https://www.carbonbrief.org/iea-bioenergy-lead-growth-renewables-over-next-five-years" target="_blank">last year's IEA report</a>. Yet as this year's figures show, despite a small dip in China itself, the global picture was buoyed by strong growth in other markets, keeping growth steady overall, rather than the expected decline.</p><h4>Number One</h4><p>The pace of expansion in renewable capacity has already <a href="https://interactive.carbonbrief.org//how-uk-transformed-electricity-supply-decade/#" target="_blank">dented the prospects</a> of fossil-fueled sources of electricity in many countries, eating into their market share and changing the way wholesale prices vary across days, months and seasons.</p><p>Nevertheless, the growth of global electricity demand has been such that generation from fossil-fuel sources has continued to rise, increasing the sector's contribution to CO2 emissions. Moreover, coal has comfortably maintained its position as the world's largest source of electricity.</p><p>IEA executive director Dr. Birol says in a press release:</p><p>"Renewables are already the world's second largest source of electricity, but their deployment still needs to accelerate if we are to achieve long-term climate, air quality and energy access goals."</p><p>Since 2010, global supplies of renewable electricity have expanded by 60%, adding enough output to power half the U.S. economy. Yet this growth was only sufficient to cover half of the increase in global electricity demand, with the other half coming from a roughly equal split of coal and gas.</p><p>Over the next five years, the IEA base case forecasts that renewables will meet a larger two-thirds share of the increase in global demand. This would mean a continuing, if somewhat diminished role for coal and gas in meeting rising demand, with extra CO2 emissions to match.</p><p>Since the majority of demand growth would be met by renewables, they would claim an increasingly large share of the global electricity mix. In the base case, renewables (red line and dots) would increase their share from 25% today to 30% in 2024, gaining five percentage points in five years. This would largely come at the expense of coal (black), which would drop to 34% of the mix, but would remain the biggest contributor to global electricity supplies.</p>

<p>Given the increase in demand overall, gas in particular, but also coal, would see their output – and emissions – increasing over the next five years in the IEA base case, despite losing market share.</p><p>The IEA's report does not include equivalent figures for its "accelerated case," where renewables grow more quickly than expected. However, Carbon Brief analysis of the IEA's capacity forecasts suggests it could mean renewables matching coal as the world's joint-largest sources of electricity.</p><p>This is shown in the chart, above right, where the renewable share of global electricity supplies would reach 32% by 2024 and coal would fall to a similar level. But even in this accelerated case, renewables would meet only 80% of the increase in demand, with gas making up the remainder.</p><p>This accelerated case for renewables could mean coal output flattening or even starting to decline out to 2024, but not at the rate required to get onto a pathway compatible with <a href="https://www.carbonbrief.org/in-depth-qa-ipccs-special-report-on-climate-change-at-one-point-five-c" target="_blank">global climate goals</a>.</p><p>As in <a href="https://www.carbonbrief.org/analysis-how-have-iea-renewable-forecasts-changed" target="_blank">previous years</a>, the IEA sets out three areas that would need to be addressed in order for the accelerated case to be realized. These are: policy and regulatory uncertainty; high investment risks in developing countries; and <a href="https://www.carbonbrief.org/in-depth-whole-system-costs-renewables" target="_blank">managing the integration</a> of variable renewables into existing grids.</p><p>(The IEA notes that in the early stages of wind and solar deployment curves in each country or region, "integration challenges are often not as serious as anticipated.")</p><p>The integration issue is a particular concern for "distributed" solar, the IEA suggests. This includes residential rooftops, but also larger commercial and industrial rooftop systems, which tend to have lower costs, the IEA says.</p><p>Given costs for these systems are now at or below the price of retail electricity in most countries – with costs set to fall a further 15-35% by 204 – there is an "explosive cocktail" of ingredients is in place for a "boom" in distributed solar capacity, Paolo Frankl, head of the IEA's renewable energy division told a pre-publication press call.</p><p>Dr. Birol told the call that this sector had "breathtaking" potential, but would need to be carefully managed so as to balance the interests of distributed solar owners, other consumers and the companies that manage electricity grids.</p>

Costa Rica aims to have net zero carbon emissions by 2050 and if it's energy production in 2019 is a sign of things to come, then it is well on its way to that goal. The small Central American nation produced the most electricity in its history during the month of May and nearly 100 percent of it was from renewable sources, according to Think Geoenergy.
<p>The 984.19 GWh of electricity generation in May surpassed all historical counts and it meant that Costa Rican Institute of Electricity (ICE), the state-owned power and telecoms provider, stopped buying energy from the Regional Electricity Market and instead started selling electricity back to other Central American nations in the marketplace, as <a href="http://www.thinkgeoenergy.com/costa-rica-reports-near-100-renewable-energy-electricity-supply-and-electricity-export/" target="_blank">Think Geoenergy</a> reported.</p>
<p>The May numbers are a crucial milestone since nearly 75 percent of the nation's <a href="https://www.ecowatch.com/tag/renewable-energy">renewable energy</a> comes from <a href="https://www.ecowatch.com/tag/hydropower" rel="noopener noreferrer">hydropower</a> produced in rivers and Costa Rica was in the midst of a historic <a href="https://www.ecowatch.com/tag/drought" rel="noopener noreferrer">drought</a> before the rainy season started in May.</p><p>"This achievement is the result of the planning and optimization of resources of the national matrix, which protects its regulatory reservoirs in dry periods – like the one just faced – while increasing the geothermal quota," said ICE in a statement, according to <a href="http://www.thinkgeoenergy.com/costa-rica-reports-near-100-renewable-energy-electricity-supply-and-electricity-export/" target="_blank">Think Geoenergy</a>.</p><p>The dry spell was the first big test of an ambitious push for clean energy, said Javier Orozco, planning director at ICE, as <a href="https://www.reuters.com/article/us-costa-rica-electricity-drought-analys/despite-drought-costa-ricas-electricity-stays-clean-but-not-cheap-idUSKCN1TK1VZ" target="_blank">Reuters</a> reported. A renewable electricity supply is one of the "most important advances" toward liberating the economy from dependence on fossil fuels, according to a national decarbonization plan launched in February.</p><p>"After these critical months, we don't think we'll need more thermal production (using fossil fuels)," said Orozco to <a href="https://www.reuters.com/article/us-costa-rica-electricity-drought-analys/despite-drought-costa-ricas-electricity-stays-clean-but-not-cheap-idUSKCN1TK1VZ" target="_blank">Reuters</a>.</p><p>Orozco added that even though rivers were exceptionally low and hydropower generation was stressed, a strong push in wind energy allowed Costa Rica to generate 97 percent of its electricity from renewable sources, during the dry summer months of January to April.</p><p>The dependence on hydropower means that the dry months can be particularly costly for ICE since it must maintain twice the hydropower capacity than it regularly uses, according to Jose Daniel Lara, a researcher at the University of California Berkeley, as <a href="https://www.reuters.com/article/us-costa-rica-electricity-drought-analys/despite-drought-costa-ricas-electricity-stays-clean-but-not-cheap-idUSKCN1TK1VZ" target="_blank">Reuters</a> reported. Those costs may increase as extreme weather associated with the global climate crisis increases the frequency, severity, and duration of droughts.</p><p>To address that concern and ICE's mounting debts, Costa Rica is looking to diversify its renewables. Wind power has grown to 15 percent, up from 4 percent in 2011. Geothermal power accounted for nearly 13 percent of energy generation in May.</p><p>Last month, Costa Rica opened a brand new geothermal plant, the country's seventh, with a projected annual generation of 410 gigawatt hours. The country's drive to harness the power contained in volcanic steam will mitigate its dependence on hydropower. Costa Rica is now the third-largest producer of geothermal power in the Americas, according to the Costa Rica based <a href="https://ticotimes.net/2019/07/24/costa-rica-inaugurates-las-pailas-ii-geothermal-plant-boosts-sustainable-energy-production" target="_blank">Tico Times</a>.</p><p>"Anyone who has doubt of what Costa Rica is capable of should come to Pailas II in Guanacaste and see what we are capable of accomplishing," said President Carlos Alvarado, as the <a href="https://ticotimes.net/2019/07/24/costa-rica-inaugurates-las-pailas-ii-geothermal-plant-boosts-sustainable-energy-production" target="_blank">Tico Times</a> reported. He added that Costa Ricans should be proud of their sustainability efforts.</p><p>The nation's push to sustainability as part of its decarbonization plan will also include a push toward cleaner public transport, improving waste management and expanding the country's forests, according to <a href="https://www.reuters.com/article/us-costa-rica-electricity-drought-analys/despite-drought-costa-ricas-electricity-stays-clean-but-not-cheap-idUSKCN1TK1VZ" target="_blank">Reuters</a>.</p>

The birthplace of coal power is changing its ways. For the first time since the industrial revolution, the United Kingdom will generate more electricity from clean energy sources like wind, solar and nuclear power rather than from fossil fuel plants, the country's National Grid said Friday, as the BBC reported.
<p>The milestone has been passed through the end of May this year. National Grid said that clean energy had slightly outpaced fossil fuels, 48 percent to 47 percent for coal and gas. The other five percent is chalked up to biomass burning, which has the potential to be carbon-neutral. The transformation reflects the growing unpopularity of coal energy, as the public increases its appetite for wind and solar power, according to the <a href="https://www.bbc.com/news/science-environment-48711649" target="_blank">BBC</a>.</p><p>The UK has a long and storied history with coal, which was home to the world's first coal-fueled power plant in the 1880s. Coal was the island nation's dominant electricity source for the next century, which led to economic leaps, but also dangerous air quality.</p><p>In a sign of the times, British politicians shunned coal and made the UK the first G7 country to commit to net-zero emissions by 2050. That target compels Britain to invest heavily in low-carbon power and to make drastic reductions in fossil fuel use, according to <a href="https://www.reuters.com/article/us-britain-electricity-mix/clean-power-to-overtake-fossil-fuels-in-britain-in-2019-idUSKCN1TL2ZW" target="_blank">Reuters</a>.</p><p>"The incredible progress that Britain has made in the past 10 years means we can now say 2019 will be the year zero-carbon power beats fossil fuel fired generation for the first time," said John Pettigrew, CEO of National Grid, as <a href="https://www.reuters.com/article/us-britain-electricity-mix/clean-power-to-overtake-fossil-fuels-in-britain-in-2019-idUSKCN1TL2ZW" target="_blank">Reuters</a> reported.</p><p>Coal's decline has been precipitous. According to data from National Grid, coal generation in the UK has plummeted from 30 percent to 3 percent, while most fossil fuel generated power comes from natural gas. On the flip side of coal, wind power has had a meteoric rise from 1 percent to 19 percent of energy power, as the <a href="https://www.bbc.com/news/science-environment-48711649" target="_blank">BBC</a> reported.</p><p>Along the way, several milestones have been reached. In May, Britain set its own modern day record for record levels of solar power for two days and for two weeks where it was <a href="https://www.bbc.com/news/business-48473259" target="_blank">completely coal-free</a>.

What's the future of coal? The answer may be blowing in the wind. Or running through our waters. Or, maybe it's at the end of a sunbeam.
Wherever the answer is found, the message is clear. Coal is on a downward trend in the U.S. and renewables are on the rise, according to a new report released by the Federal Energy Regulatory Commission, or FERC.
<p>The report shows that renewable energies had slightly more installed capacity than coal, as <a href="https://edition.cnn.com/2019/06/11/business/renewable-energy-coal-capacity/index.html" target="_blank">CNN</a> reported.</p><p>This means that power plants are capable of producing more energy from clean sources than they are from coal.</p><p>"Coal has no technology path," said Jeff McDermott, managing partner at Greentech Capital Advisors, a boutique investment bank focused on clean energy, as reported by <a href="https://edition.cnn.com/2019/06/11/business/renewable-energy-coal-capacity/index.html" target="_blank">CNN</a>. "It's got nowhere to go but extinction."</p><p>While the discrepancy is slight, the trend is clear. The non-profit SUN DAY, which campaigns for renewable energy, analyzed the data. A press release by the non-profit SUN DAY Campaign, which analyzed the data, noted that the new additions of <a href="http://www.ecowatch.com/tag/wind">wind</a>, <a href="http://www.ecowatch.com/tag/solar">solar</a> and <a href="https://www.ecowatch.com/tag/hydropower">hydropower</a> to the electrical grid " was enough to push renewable energy's share of total available installed U.S. generating capacity up to 21.56 percent. By comparison, coal's share dropped to 21.55 percent (down from 23.04 percent a year ago)."</p><p>Yet, that number does not take into account solar panels that people put on their roofs, which accounts for roughly 30 percent of the nation's solar powered electricity, according to <a href="https://electricenergyonline.com/article/energy/category/generation/52/772999/u-s-renewable-energy-generating-capacity-has-now-surpassed-coal.html" target="_blank">SUN DAY</a>. "That would suggest that solar capacity is now actually 4% — or more — of the nation's total and could increase by more than 20,000 megawatts by May 2022," according to the <a href="https://electricenergyonline.com/article/energy/category/generation/52/772999/u-s-renewable-energy-generating-capacity-has-now-surpassed-coal.html" target="_blank">press release</a>.</p>
<p>Coal's downward trend has been ongoing since its peak in 2008 and has no end in sight. Coal consumption has dropped by 39 percent to the lowest level in 40 years, according to the <a href="https://www.eia.gov/todayinenergy/detail.php?id=39792" target="_blank">US Energy Information Administration</a>, as reported by <a href="https://edition.cnn.com/2019/06/11/business/renewable-energy-coal-capacity/index.html" target="_blank">CNN</a>.</p><p>The rise of renewables over coal has happened despite President <a href="http://www.ecowatch.com/tag/donald-trump">Trump</a>'s promise to slash environmental regulations to revive the coal industry. Analysts say the shift toward renewables is being driven more by economics than regulation. "The government can tap on the brakes or accelerate this movement — but this progress will continue moving forward," said Matthew Hoza, senior energy analyst at consulting firm BTU Analytics, as reported by <a href="https://edition.cnn.com/2019/06/11/business/renewable-energy-coal-capacity/index.html" target="_blank">CNN</a>. "For the most part, the public is calling for renewables."</p><p>Power companies are responding to the public's demand by investing heavily in renewable energies. Con Edison invested $2.1 billion in wind and solar projects last year, making it the second largest solar producer in North America. Minnesota based Xcel Energy once championed coal, but has now pledged to produce only carbon-free electricity by 2050, according to <a href="https://edition.cnn.com/2019/06/11/business/renewable-energy-coal-capacity/index.html" target="_blank">CNN</a>.</p><p>The move away from coal prompted McDermott, the Greentech Capital Partner, to call the Trump's plan to save coal a "ridiculous concept" akin to trying to save the rotary phone, saying, "The public doesn't want it. And the world can't take it," McDermott said to <a href="https://edition.cnn.com/2019/06/11/business/renewable-energy-coal-capacity/index.html" target="_blank">CNN</a>. "The Trump administration is playing political favorites, trying to prop up an industry that is technologically obsolete."</p>

Thousands of hydroelectric dams are under construction around the world, mainly in developing countries. These enormous structures are one of the world's largest sources of renewable energy, but they also cause environmental problems.
<p><a href="https://www.ecowatch.com/tag/hydropower">Hydropower</a> dams <a href="https://energyeducation.ca/encyclopedia/Water_quality_degradation_from_hydropower" target="_blank">degrade water quality along rivers</a>. Water that flows downstream from the dams is depleted of oxygen, which harms many aquatic animals. The reservoirs above dams are susceptible to harmful algal blooms, and can leach toxic metals such as mercury from submerged soil.</p><p>We wanted to know whether dams also impact river systems farther away, at the coastlines where <a href="http://www.ecowatch.com/tag/rivers">rivers</a> flow into the sea. So we performed a <a href="http://doi.org/10.1126/sciadv.aau9875" target="_blank">natural experiment comparing four rivers</a> along Mexico's Pacific coast — two that are dammed and two that remain free-flowing. We found that damming rivers has measurable negative ecologic and economic effects on coastal regions more than 60 miles downstream.</p>
<h2>Feeding or Starving Coastlines</h2><p>We studied four river outflows along the Pacific Coast of Mexico in the states of Sinaloa and Nayarit. Two of these were from the San Pedro and Acaponeta rivers, which are relatively unrestricted, with over 75% of their flow unobstructed.</p><p>The other two outflows came from the nearby Santiago and Fuerte rivers, which have over 95% of their flow retained in reservoirs. In addition to restricting water flow, these reservoirs trap sediments — over 1 million tons per year along the two rivers combined.</p><p>In unobstructed rivers, sediment flows downstream and is eventually deposited along the coast, helping to stabilize the shoreline and sometimes even to build it up. We found that this was happening along the free-flowing Acaponeta and San Pedro rivers.</p><p>However, because the sediment from the dammed Santiago and Fuerte rivers is no longer carried downstream, wave action takes over at the coast. At the mouths of these two rivers, we found that waves were eroding up to 33 hectares of combined land — equivalent to about 62 football fields — each year, with widespread ecologic and economic effects on the surrounding regions.</p>
<img lazy-loadable="true" src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xOTUzOTc3MS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY0ODg3MDY2MX0.64bEwSTZiIy4D-loe57hnKHBBK37cf4WBqj3UhECKyw/img.jpg?width=980" id="65759" class="rm-shortcode" data-rm-shortcode-id="30cd5fb4eaa720d8ba3b5d0f19e30cad" data-rm-shortcode-name="rebelmouse-image" />
The dammed Fuerto and Santiago Rivers show greater erosion where they reach the Pacific coast than the free-flowing San Pedro and Acaponeta rivers. Images at right show coastline changes during the two periods: blue indicates land accretion, red indicates erosion.
Ezcurra et al., 2019., CC BY-NC
<h2>The Ecology of Healthy Coasts</h2><p>Our field research clearly showed that coastal instability resulting from sediment loss at the mouths of the dammed rivers was harming ecosystems along the shore. For example, we found that coastal regions downstream of free-flowing rivers had significantly more plant diversity. Many of these plants were found only in coastal areas, and therefore had high conservation value.</p><p>Coastal erosion due to lack of sediment input from the rivers also reduces critical nursery habitat, such as mangrove forest, where many commercially important fish species <a href="https://doi.org/10.1073/pnas.0804601105" target="_blank">spend their juvenile stage</a>. We found that fishing activity at the mouth of the free-flowing San Pedro River was much higher than around the mouth of the dammed Fuerte River. This loss of fishing potential comes at a cost of around $1.3 million every year.</p><p>Reduced sediment flow also deprives coastal estuaries of nutrients. Lucrative shrimp and oyster fisheries in the region we studied rely heavily on nutrient inputs from rivers. In the San Pedro River region, these fisheries generate around $5.8 million yearly; near the dammed rivers, they have been all but abandoned.</p><p>Coastal mangrove wetlands also <a href="https://theconversation.com/mangroves-protect-coastlines-store-carbon-and-are-expanding-with-climate-change-81445" target="_blank">protect shorelines</a> from hurricanes and tropical storms, and serve as recreational areas and conservation habitat for <a href="http://www.ecowatch.com/tag/wildlife" target="_self">wildlife</a>. Knowing this, we calculated that the loss of these ecosystem services around the dammed rivers totals $3.9 million annually.</p>

<p>Still another valuable function that mangrove wetlands perform is <a href="https://theconversation.com/mapping-the-worlds-blue-carbon-hot-spots-in-coastal-mangrove-forests-105793" target="_blank">storing "blue carbon"</a> in plant tissue and <a href="http://www.ecowatch.com/tag/soil">soils</a>, reducing the effects of <a href="https://www.ecowatch.com/tag/climate-change">climate change</a>. But when coastlines recede and mangroves are destroyed, this carbon is released. We calculated that mangrove loss in our study region represented a loss of around $130,000 in annual carbon trading potential for this region.<br></p><p>Adding up all of the ecological services that coastal ecosystems provide, we estimate that the economic consequences of shoreline loss around the Santiago and Fuerte rivers related to hydroelectric damming totaled well over $10 million yearly.</p>
<h2>Letting More Sediment Flow</h2><p>Because sediments are so essential to areas around river mouths, <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1002/2013EF000184" target="_blank">reducing sediment trapping</a> behind dams could mitigate some harmful impacts on coastal areas. There are several ways to do this — notably, sediment bypassing, or diverting a portion of the sediments flowing from upriver around dams and allowing it to rejoin the river downstream.</p><p>This strategy can be included in new construction or incorporated into existing dams. In addition to reducing dams' environmental impacts, it also increases dams' service lives by reducing the rate at which their reservoirs fill up with silt.</p><p>To date, environmental impact assessments of large inland dams have often failed to properly analyze the impacts that these dams will have downriver on coastlines, estuaries, deltas and lagoons. Our study shows how important it is to fully account for dams' environmental and economic impacts along coasts and basins.</p>

<p>Mexico may be at a juncture in its approach to hydropower. The Mexican government recently contracted with Hydro-Quebec, the world's largest hydroelectric power producer, to <a href="https://www.eluniversal.com.mx/english/hydro-quebec-boost-clean-energy-generation-mexico" target="_blank">revamp existing dams across the country</a>. And a recent study by a Mexican nongovernment organization, SuMar-Voces por la Naturaleza, <a href="https://aristeguinoticias.com/2702/mexico/hidroelectrica-las-cruces-no-es-necesaria-hoy-ni-a-futuro-revela-estudio/" target="_blank">reported</a> that a long-disputed proposal to build a new hydroelectric dam at Las Cruces is neither financially feasible nor needed to meet energy demand for the region, prompting national groups to call for the final cancellation of the project.<br></p><p>We believe that Mexico and all nations working to develop efficient, low-impact energy sources should take a holistic approach to future dam-related projects, so they can weigh their potentially harmful consequences. The coastal effects that we documented should be part of those reviews.</p>

Only a little more than one-third of the world's 246 longest rivers remain free-flowing, drastically reducing the diverse benefits that healthy rivers provide to people and nature everywhere, according to a new study by World Wildlife Fund (WWF) and partners.
<p>A team of researchers from WWF, McGill University, and other institutions studied about 7.5 million miles of rivers worldwide to determine whether they're well connected. They found that only 37 percent are free-flowing — meaning they're largely unaffected by human-made changes to its flow and connectivity. <a href="https://www.ecowatch.com/tag/dams">Dams</a> built in the wrong place and <a href="https://www.ecowatch.com/climate-change/">climate change</a> are impacting river health worldwide, and the planet's remaining free-flowing rivers are largely restricted to remote regions of the Arctic, the Amazon Basin and the Congo Basin.</p><h2>Vanishing Free-Flowing Rivers</h2><p>Long free-flowing rivers are vanishing. Around the world, rivers are becoming increasingly fragmented by dams and other development — such as roads or dikes — endangering freshwater ecosystems and the people and wildlife that rely on them. Free-flowing rivers transport water, nutrients and species that sustain biodiversity and benefit millions of people. To help countries and communities better protect their freshwater resources, WWF and partners came up with a technical definition of a free-flowing river and then created a first-of-its-kind, scientifically backed map — a <a href="http://dx.doi.org/10.1038/s41586-019-1111-9" target="_blank">comprehensive inventory</a> of the world's last free-flowing rivers, rivers with good connectivity and impacted rivers.</p><h2>1. Mura River — Slovenia </h2>

</p>
<p>Called the "Amazon of Europe," the Mura River provides critical habitat for endangered and rare species such as otters, Danube salmon and black stork. After urging from WWF and others, in February 2019, the Slovenian government signed an agreement to stop all hydropower plant development that would devastate the Mura.</p><h2>2. Usumacinta River — Mexico </h2>
<p class="shortcode-media shortcode-media-rebelmouse-image">

</p>
<p>In June 2018, guided by WWF and partners, Mexico established water reserves across nearly 300 river basins, guaranteeing water supplies for 45 million people for the next 50 years. Ninety-three percent of the water in the Usumacinta — the longest, most biodiverse river in Central America and one of Mexico's — is now federally protected.<br/></p><h2>3. Bita River - Colombia </h2>
<p class="shortcode-media shortcode-media-rebelmouse-image">
<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xOTQ1NjExMi9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTYzODAyOTc4OX0.x4bRFXGDcpzWl6EcBNPgWuQH0ZhkS-3hMwLe_5Js0Zs/img.png?width=980" id="a29ad" class="rm-shortcode" data-rm-shortcode-id="2f6f8caa2cc98cacd3e609bc42832b98" data-rm-shortcode-name="rebelmouse-image" />
</p>
<p>The Colombian government named the Bita River basin a Ramsar site — a wetland of international importance — in June 2018, thanks in large part to the work of WWF and partners. Covering 825,000 hectares, it's the largest of the country's 11 Ramsar sites and one of the few in the world to encompass an entire free-flowing river watershed.<br/></p><h2>4. Paraguay Basin — Brazil </h2>
<p class="shortcode-media shortcode-media-rebelmouse-image">
<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xOTQ1NjExOS9vcmlnaW4ucG5nIiwiZXhwaXJlc19hdCI6MTY3NzUyOTA0M30.uc-LALAFEzniDc8vN9y8a6AoRdbEsRlYmfaRmKgmLQM/img.png?width=980" id="455d6" class="rm-shortcode" data-rm-shortcode-id="19979a4b80ea38807c6cdc7e41af4c17" data-rm-shortcode-name="rebelmouse-image" />
</p>
<p>More than 100 dams planned for the Upper Paraguay Basin could hurt water supplies, biodiversity and local communities. After tremendous efforts from a coalition including WWF, Brazil's National Water Agency suspended new dam development there until May 2020. But the suspension only applies to rivers under federal jurisdiction — so just 20 of the 100 dams will be suspended.<br/></p><h2>5. Luangwa River — Zambia </h2>
<p class="shortcode-media shortcode-media-rebelmouse-image">

</p>
<p>The Luangwa, which is free but impacted by a dam on a nearby river, is at risk. A proposed dam at Ndevu Gorge threatens this wild waterway, which shelters abundant wildlife and human populations. In Zambia, WWF is advocating on behalf of people and nature, pushing the government to reconsider its energy plans and ensuring that local people maintain their rights to natural resources.<br/></p><h2>6. Irrawaddy and Salween Rivers — Myanmar</h2>
<p class="shortcode-media shortcode-media-rebelmouse-image">

<p>In Myanmar, an in-depth Strategic Environmental Assessment recommended that the main stems of the Irrawaddy and Salween rivers — two of the last long free-flowing rivers in southeast Asia — should remain free of dams. But there is still risk, making alternative energy such as solar and wind power even more important for people, rivers, and the country's economy.</p><p><strong><a href="https://www.worldwildlife.org/pages/free-flowing-rivers/" target="_blank">Learn more about free-flowing rivers and WWF's efforts to protect them</a>.</strong></p>

<h2>Mapping Downs</h2><p>Dams provide safe drinking water and electricity to millions of people. But when built in the wrong place — for instance, a river's main stem — they can impede a river's flow, causing drastic declines in biodiversity and affecting fish migration, agriculture and livelihoods. Today there are more than 60,000 major dams around the world — a number that's increasing to meet demand for hydropower. WWF is helping national governments, industries and developers consider both the long-term impacts on local people and habitats and other potential alternative options for meeting water and energy supply needs, as well as helping them identify the best opportunities for river restoration projects. Solar and wind prices are going down, making them attractive alternatives.</p>

Illegal deforestation in Pirititi indigenous land, Roraima, Brazil on May 8, 2018. Felipe Werneck / Ibama / CC BY-SA 2.0
By Robert T. Walker
Over the past 25 years that I have been conducting environmental research in the Amazon, I have witnessed the the ongoing destruction of the world's biggest rainforest. Twenty percent of it has been deforested by now—an area larger than Texas.
I therefore grew hopeful when environmental policies began to take effect at the turn of the millennium, and the rate of deforestation dropped from nearly 11,000 square miles per year to less than 2,000 over the decade following 2004.
<p>
But a new political climate in Brazil, which set in even before President <a href="https://theconversation.com/what-bolsonaros-presidency-means-for-brazil-5-essential-reads-105894" target="_blank">Jair Bolsonaro</a> took office in January 2019, has led to a <a href="https://www.theguardian.com/environment/2018/nov/24/brazil-records-worst-annual-deforestation-for-a-decade" target="_blank">recent increase in the pace of rainforest felling</a>. And Bolsonaro, a former army officer, made <a href="https://theconversation.com/jair-bolsonaros-brazil-would-be-a-disaster-for-the-amazon-and-global-climate-change-104617" target="_blank">Amazonian development</a> a core campaign pledge.

</p><h2>Damming the Tapajós<br>
</h2><p>
At stake is what becomes of the region around the <a href="http://www.earthisland.org/journal/index.php/magazine/entry/to_keep_a_river_running/" target="_blank">Tapajós River</a>, one of the Amazon's largest tributaries and home to about <a href="https://pib.socioambiental.org/en/Povo:Munduruku#Location_and_population" target="_blank">14,000 Munduruku tribal people</a>. The Munduruku have until now successfully slowed down and seemingly halted many efforts to turn the Tapajós into the "<a href="https://doi.org/10.1080/00139157.2018.1418994" target="_blank">Mississippi of Brazil</a>."
</p><p>
The Tapajós River is the Amazon's last undammed <a href="https://www.doi.org/10.1126/science.225.4658.129" target="_blank">clearwater tributary</a>. The basin that surrounds it is roughly equal to 15 percent of the Brazilian Amazon region and about the size of France. This remote area has a <a href="https://www.csmonitor.com/Environment/2018/0924/Camp-Amazon-Inside-the-lungs-of-the-Earth" target="_blank">great deal of biodiversity</a>, and its trees store large quantities of carbon.
</p><p>
Because the Amazon <a href="https://www.ecowatch.com/tag/rainforests">rainforest</a> absorbs a lot of the carbon emitted through the burning of fossil fuels, <a href="https://doi.org/10.1111/gcb.14413" target="_blank">climate scientists</a> consider its preservation key to preventing an uptick in the pace of global warming.
</p><p class="shortcode-media shortcode-media-rebelmouse-image">

</p><p>
Brazil is planning to build a series of big new <a href="https://www.theguardian.com/world/2017/oct/05/brazil-amazon-tapajos-hydrovia-scheme" target="_blank">hydroelectric dams and webs of waterways</a>, <a href="https://lab.org.uk/tapajos-under-attack-8-the-rush-to-turn-the-amazon-into-a-soy-transport-corridor/" target="_blank">rail lines, ports and roads</a> that can overcome logistical obstacles standing in the way of <a href="https://news.mongabay.com/2018/10/grainrail-2nd-revolution-in-brazilian-agribusiness-and-amazon-threat/" target="_blank">exporting commodities and other goods</a>.<br>
</p><p>
The government did suspend plans to build an <a href="https://www.theguardian.com/world/2016/apr/22/brazil-amazon-dam-project-suspended-indigenous-munduruku-sao-luiz-do-tapajos" target="_blank">8,000-megawatt dam</a> at the heart of this sprawling project in 2016. At the time, it cited the "unviability of the project given the indigenous component" and stated it would <a href="https://news.mongabay.com/2018/01/brazil-announces-end-to-amazon-mega-dam-building-policy/" target="_blank">stop building big dams</a> in 2018, before Bolsanaro took office.
</p><p>
Yet many observers remain very concerned about how Bolsonaro's presidency will affect the Munduruku and the rainforest they protect. Groups like <a href="https://www.internationalrivers.org/resources/about-international-rivers-3679" target="_blank">International Rivers</a>—a nonprofit dedicated to the "protection of rivers and the rights of communities that depend on them"—are not about to declare victory.
</p><h2>South American Gambit</h2><p>
Brazil's Amazon development plans are part of a broader gambit that includes all the <a href="http://www.iirsa.org/" target="_blank">South American nations</a>. First conceived in 2000, the Initiative for the Integration of the Regional Infrastructure of South America is designed to build a continental economy through new infrastructure that provides electricity for industrialization and facilitates trade and transportation.
</p><p>
Known widely by its Spanish and Portuguese abbreviations as IIRSA, this initiative is turning <a href="https://onlinelibrary.wiley.com/doi/10.1111/btp.12610" target="_blank">the Amazon</a>, <a href="https://www.britannica.com/place/Amazon-Rainforest" target="_blank">60 percent</a> of which is located on Brazilian territory, into a source of <a href="https://www.ecowatch.com/tag/hydropower">hydropower</a> and a transportation hub connecting the Atlantic and Pacific oceans. It will become easier to <a href="https://www.hellenicshippingnews.com/brazil-logistics-worry-soy-farmers-exporters-as-harvest-starts/" target="_blank">ship Brazilian soybeans to global markets</a>, and manufacturing will expand, stimulating <a href="https://doi.org/10.1080/00139157.2018.1418994" target="_blank">population growth in the Amazon</a>.
</p><p>
The <a href="https://doi.org/10.1111/btp.12610" target="_blank">blueprint for this bid to develop the Amazon</a>, which also includes portions of <a href="https://rainforests.mongabay.com/amazon/amazon_countries.html" target="_blank">Peru, Bolivia</a> and six other countries, calls for building more than 600 dams, 12,400 miles of waterways, about 1.2 million miles of roads, a transcontinental railway and a system of ports, much of it in the tropical wilderness.
</p><h2>New Wave of Development</h2><p class="shortcode-media shortcode-media-rebelmouse-image">
<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8xOTEyMzc5MC9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY3MTI5NjQwMn0.dtkBFc31ki73jwXyfglyY8-ha9VFUtmEB_uJxY0c9Nk/img.jpg?width=980" id="8422e" class="rm-shortcode" data-rm-shortcode-id="bb44e222dd88826bc2902be0af801d67" data-rm-shortcode-name="rebelmouse-image">

</p><p>
Bolsonaro has not yet confronted the Munduruku or taken concrete actions to keep his promises about developing the Amazon. But he has taken steps that point in this direction with the <a href="https://www.doi.org/10.1126/science.aaw7608" target="_blank">officials he has selected for key posts</a>. He has also <a href="https://www.abc.net.au/news/2019-01-02/new-brazilian-president-removes-indigenous-protections/10680166" target="_blank">transferred responsibilities</a> for demarcating indigenous lands from the Ministry of Justice to the Ministry of Agriculture, which an <a href="https://www.dw.com/en/brazils-indigenous-people-fight-back-against-bolsonaros-attacks-on-amazon/a-46974782" target="_blank">agricultural lobbyist is running</a>.<br>
</p><p>
The new Brazilian president's plans for the Amazon come on the heels of decades of deforestation following the construction of roads and hydropower facilities during the 1960s and 1970s. This initial wave of construction opened the sparsely populated region to an influx of newcomers, and contributed to the <a href="https://www.tandfonline.com/doi/pdf/10.1080/24694452.2018.1489215?needAccess=true" target="_blank">destruction of about a fifth</a> of the forest over four decades.
</p><p>
Then came a wave of <a href="https://theconversation.com/brazils-thriving-soy-industry-threatens-its-forests-and-global-climate-targets-56973" target="_blank">stronger environmental policies</a>—such as the stricter enforcement of logging laws, the expansion of protected areas and the voluntary decision by soybean farmers to refrain from clearing the forest—<a href="https://www.doi.org/10.1126/science.1182108" target="_blank">which lowered Brazil's Amazon deforestation rate</a> after 2000. It seemed to me and others that a new era of <a href="https://rainforests.mongabay.com/amazon/deforestation_calculations.html" target="_blank">Amazonian conservation had dawned</a>.
</p><p>
But that was before I understood the full implications of the Initiative for the Integration of the Regional Infrastructure of South America.
</p><p>
This plan is far more ambitious than earlier infrastructure projects which were completed by the <a href="https://doi.org/10.1080/24694452.2018.1489215" target="_blank">end of the 1970s</a>, and I believe that it could wreak even more destruction.
</p><p>
Should all of its components be built, the new transportation and energy infrastructure would be likely to spark a new wave of deforestation that I fear could have disastrous impacts on the indigenous communities living in the region. The new projects need only to repeat what the earlier projects did. This would bring total deforestation to 40 percent.
</p><p>
Climate scientists such as <a href="https://www.wri.org/profile/carlos-nobre" target="_blank">Carlos Nobre</a> worry that this magnitude of forest loss would push the Amazon to a "tipping point" and undermine the <a href="https://doi.org/10.1016/j.cosust.2009.07.003" target="_blank">process of rainfall recycling</a>, which <a href="https://forestsnews.cifor.org/54600/rainfall-recycling-trees-rainmakers?fnl=en" target="_blank">replenishes the Amazon's supply of water</a>. The outcome would be a drier climate in the Amazon, which has already begun to <a href="https://doi.org/10.1038/s41467-018-05668-6" target="_blank">experience droughts</a>, and the transformation of the forest into savanna. Indigenous people would suffer, and the Amazon's biodiversity would disappear.
</p><p>
A massive increase in the pace of Amazonian deforestation could bring about <a href="https://www.ecowatch.com/tag/climate-change">climatic changes</a> in both South and North America. Scientists predict that precipitation would decline in many areas of the Americas, including the <a href="https://www.doi.org/10.1126/sciadv.aat2340" target="_blank">southeastern part of South America</a> and the <a href="https://journals.ametsoc.org/doi/pdf/10.1175/JHM406.1" target="_blank">Mississippi River Valley</a>. The whole world would suffer from reduced agricultural production in these two regions, which are <a href="http://www.agriacorp.com/market.asp?id=10" target="_blank">important global suppliers</a> of agricultural commodities like <a href="https://www.nps.gov/miss/riverfacts.htm" target="_blank">corn and soybeans</a>.

</p><h2>Attacking the Amazon<br>
</h2><p>
To be sure, some of this construction is already underway in Brazil, particularly for hydropower. So far, <a href="https://www.popsci.com/environmental-damage-amazon-river-dams" target="_blank">140 dams</a> have either been built or are under construction, notably <a href="https://www.economist.com/the-americas/2013/05/04/the-rights-and-wrongs-of-belo-monte" target="_blank">the Belo Monte Dam</a> on the Xingu River and the <a href="https://doi.org/10.1016/j.envsci.2013.11.004" target="_blank">Santo Antônio and Jirau</a> dams on the Madeira Rivers. And Bolsonaro's predecessors had <a href="https://doi.org/10.1080/00139157.2018.1418994" target="_blank">downsized some of the Amazon's protected areas to facilitate development</a>.
</p><p>
These <a href="https://doi.org/10.1073/pnas.0806059106" target="_blank">protected tracts of land</a> cover 43 percent of the Brazilian Amazon and are essential to maintaining <a href="http://www.ecowatch.com/tag/biodiversity">biodiversity</a> and <a href="https://phys.org/news/2017-02-carbon-uptake-amazon-forests-region.html" target="_blank">sequestering carbon</a>.
</p><p>
When Bolsonaro addressed world leaders at the World Economic Forum in Davos, Switzerland for the first time, he promised to protect the environment in his country—which he called "<a href="https://qz.com/1530219/brazils-bolsonaro-tells-davos-he-wants-to-protect-the-amazon/" target="_blank">a paradise</a>."
