The fourth edition of the annual Solar Means Business Report, which identifies major commercial solar projects and ranks America’s top 25 corporate solar users, was released today by the Solar Energy Industries Association (SEIA).
The report revealed that the amount of solar installed by America’s top companies has nearly tripled since the first edition was released.
Walmart is once again America’s commercial solar leader for the third year in a row with nearly 142 megawatts (MW) installed at 348 installations across its locations.
1. #ActOnClimate
The release of SEIA’s new rankings of the top corporate solar users in America coincides with commitments made by Walmart and 80 other U.S. companies to the American Business Act on Climate Pledge.
By signing the pledge, these companies provided new and ongoing plans for reducing, avoiding and mitigating greenhouse gas (GHG) levels in their operations. The pledge was also a showing of strong support to leaders from around the world who are meeting in Paris this week to solidify broader commitments from countries that are working to address climate change.

These companies are influential and successful brands that have operations in all 50 states, employ more than nine million people, represent more than $3 trillion in annual revenue and have a combined market capitalization of more than $5 trillion.
Deploying more clean energy is a significant way these companies are reducing their emissions and building more sustainable businesses.
In 2014, 26 percent of Walmart’s electricity was generated from renewable sources. In fact, Walmart pledged to double the number of on-site solar energy projects at its U.S. stores, Sam’s Clubs and distribution centers by 2020, compared with its 2013 baseline.
2. #SolarMeansBiz
Choosing to go solar is a surefire way for companies to take action on climate, but it’s also a smart business decision.
For commercial users, average electricity rates have increased more than 20 percent in 10 years, moving from eight cents per kilowatt-hour (kWh) to more than 10 cents per kWh.
This report shows that companies are taking advantage of this cost savings by increasingly adopting solar or adding to their existing systems to power their operations.
While the report does not provide a complete dataset of corporate solar systems in the U.S., the companies sampled installed 1,686 systems totaling 907 MW, generating enough electricity to power more than 158,000 homes.
This represents a 59 percent increase over the findings of last year's report.
Commercial solar prices are the lowest they have ever been and are continuing to fall, making solar a cost-effective decision that pays in both dividends for the environment and the bottom line.

In a wildfire, hurricane, or other disaster, people with pets should heed the Humane Society's advice: If it isn't safe for you, it isn't safe for your animals either.
<p>Whether your charge is a lap dog, bird, outdoor cat, or farm animal, planning ahead for a potential evacuation can help you protect your animals and also first responders, who may risk their safety to save your pets.</p><p>Take the following measures now to help keep family pets safe should an evacuation become necessary:</p>
<p><em>Reposted with permission from </em><em><a href="https://yaleclimateconnections.org/2021/01/how-to-evacuate-with-pets-during-a-wildfire-hurricane-or-other-disaster/" target="_blank">Yale Climate Connections</a>.</em><a href="https://www.ecowatch.com/r/entryeditor/2650067972#/" target="_self"></a></p>
1. Stay Informed
<p>A first order of business in pet evacuation planning is to understand and be ready for the possible threats in your area. Visit <a href="https://www.ready.gov/be-informed" target="_blank">Ready.gov</a> to learn more about preparing for potential disasters such as floods, hurricanes, and wildfires. Then pay attention to related updates by tuning <a href="http://www.weather.gov/nwr/" target="_blank">NOAA Weather Radio</a> to your local emergency station or using the <a href="https://www.fema.gov/mobile-app" target="_blank">FEMA app</a> to get National Weather Service alerts.</p>2. Ensure Your Pet is Easily Identifiable
<p><span>Household pets, including indoor cats, should wear collars with ID tags that have your mobile phone number. </span><a href="https://www.avma.org/microchipping-animals-faq" target="_blank" rel="noopener noreferrer">Microchipping</a><span> your pets will also improve your chances of reunion should you become separated. Be sure to add an emergency contact for friends or relatives outside your immediate area.</span></p><p>Additionally, use <a href="https://secure.aspca.org/take-action/order-your-pet-safety-pack" target="_blank" rel="noopener noreferrer">'animals inside' door/window stickers</a> to show rescue workers how many pets live there. (If you evacuate with your pets, quickly write "Evacuated" on the sticker so first responders don't waste time searching for them.)</p>3. Make a Pet Evacuation Plan
<p> "No family disaster plan is complete without including your pets and all of your animals," says veterinarian Heather Case in <a href="https://www.youtube.com/watch?v=Q9NRJkFKAm4" target="_blank">a video</a> produced by the American Veterinary Medical Association.</p><p>It's important to determine where to take your pet in the event of an emergency.</p><p>Red Cross shelters and many other emergency shelters allow only service animals. Ask your vet, local animal shelters, and emergency management officials for information on local and regional animal sheltering options.</p><p>For those with access to the rare shelter that allows pets, CDC offers <a href="https://www.cdc.gov/healthypets/emergencies/pets-in-evacuation-centers.html" target="_blank">tips on what to expect</a> there, including potential health risks and hygiene best practices.</p><p>Beyond that, talk with family or friends outside the evacuation area about potentially hosting you and/or your pet if you're comfortable doing so. Search for pet-friendly hotel or boarding options along key evacuation routes.</p><p>If you have exotic pets or a mix of large and small animals, you may need to identify multiple locations to shelter them.</p><p>For other household pets like hamsters, snakes, and fish, the SPCA recommends that if they normally live in a cage, they should be transported in that cage. If the enclosure is too big to transport, however, transfer them to a smaller container temporarily. (More on that <a href="https://www.spcai.org/take-action/emergency-preparedness/evacuation-how-to-be-pet-prepared" target="_blank" rel="noopener noreferrer">here</a>.)</p><p>For any pet, a key step is to establish who in your household will be the point person for gathering up pets and bringing their supplies. Keep in mind that you may not be home when disaster strikes, so come up with a Plan B. For example, you might form a buddy system with neighbors with pets, or coordinate with a trusted pet sitter.</p>4. Prepare a Pet Evacuation Kit
<p>Like the emergency preparedness kit you'd prepare for humans, assemble basic survival items for your pets in a sturdy, easy-to-grab container. Items should include:</p><ul><li>Water, food, and medicine to last a week or two;</li><li>Water, food bowls, and a can opener if packing wet food;</li><li>Litter supplies for cats (a shoebox lined with a plastic bag and litter may work);</li><li>Leashes, harnesses, or vehicle restraints if applicable;</li><li>A <a href="https://www.avma.org/resources/pet-owners/emergencycare/pet-first-aid-supplies-checklist" target="_blank">pet first aid kit</a>;</li><li>A sturdy carrier or crate for each cat or dog. In addition to easing transport, these may serve as your pet's most familiar or safe space in an unfamiliar environment;</li><li>A favorite toy and/or blanket;</li><li>If your pet is prone to anxiety or stress, the American Kennel Club suggests adding <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">stress-relieving items</a> like an anxiety vest or calming sprays.</li></ul><p>In the not-unlikely event that you and your pet have to shelter in different places, your kit should also include:</p><ul><li>Detailed information including contact information for you, your vet, and other emergency contacts;</li><li>A list with phone numbers and addresses of potential destinations, including pet-friendly hotels and emergency boarding facilities near your planned evacuation routes, plus friends or relatives in other areas who might be willing to host you or your pet;</li><li>Medical information including vaccine records and a current rabies vaccination tag;</li><li>Feeding notes including portions and sizes in case you need to leave your pet in someone else's care;</li><li>A photo of you and your pet for identification purposes.</li></ul>5. Be Ready to Evacuate at Any Time
<p>It's always wise to be prepared, but stay especially vigilant in high-risk periods during fire or hurricane season. Practice evacuating at different times of day. Make sure your grab-and-go kit is up to date and in a convenient location, and keep leashes and carriers by the exit door. You might even stow a thick pillowcase under your bed for middle-of-the-night, dash-out emergencies when you don't have time to coax an anxious pet into a carrier. If forecasters warn of potential wildfire, a hurricane, or other dangerous conditions, bring outdoor pets inside so you can keep a close eye on them.</p><p>As with any emergency, the key is to be prepared. As the American Kennel Club points out, "If you panic, it will agitate your dog. Therefore, <a href="https://www.akc.org/expert-advice/home-living/create-emergency-evacuation-plan-dog/" target="_blank" rel="noopener noreferrer">pet disaster preparedness</a> will not only reduce your anxiety but will help reduce your pet's anxiety too."</p>Evacuating Horses and Other Farm Animals
<p>The same basic principles apply for evacuating horses and most other livestock. Provide each with some form of identification. Ensure that adequate food, water, and medicine are available. And develop a clear plan on where to go and how to get there.</p><p>Sheltering and transporting farm animals requires careful coordination, from identifying potential shelter space at fairgrounds, racetracks, or pastures, to ensuring enough space is available in vehicles and trailers – not to mention handlers and drivers on hand to support the effort.</p><p>For most farm animals, the Red Cross advises that you consider precautionary evacuation when a threat seems imminent but evacuation orders haven't yet been announced. The American Veterinary Medical Association has <a href="https://www.avma.org/resources/pet-owners/emergencycare/large-animals-and-livestock-disasters" target="_blank">more information</a>.</p>Bottom Line: If You Need to Evacuate, So Do Your Pets
<p>As the Humane Society warns, pets left behind in a disaster can easily be injured, lost, or killed. Plan ahead to make sure you can safely evacuate your entire household – furry members included.</p>From Your Site Articles

The growing Texas solar industry is offering jobs to unemployed oil and gas professionals. King Lawrence / Getty Images
The growing Texas solar industry is offering a safe harbor to unemployed oil and gas professionals amidst the latest oil and gas industry bust, this one brought on by the novel coronavirus pandemic, the Houston Chronicle reports.
<p>With the fracking sector in turmoil, many workers are looking to apply their skills — from construction to negotiating land use agreements — to the solar industry. </p><p>"No question, we are getting workers moving over from oil and gas," Kevin Smith, Lighthouse BP's CEO in the Americas, said. "A lot of the oil and gas skills are applicable to solar." </p><p>Renewables are the fastest-growing energy sector in the country and Texas' topography, climate, and grid make it an attractive market for solar energy. </p><p>"Clean energy is growing and growing fast in Texas... This is where the jobs are going to be and where the economy is heading," Raj Prahbu, CEO of the Austin-based research firm Mercom Capital Group, told the Chronicle. </p><p>"If you're not going to make the shift, you're going to be left behind."</p>

A 2019 Basel Convention amendment targeting plastic waste exports went into effect on Jan. 1. Boris Horvat / AFP / Getty Images
This month, a new era began in the fight against plastic pollution.
<p>In 2019, 187 nations within the United Nations amended the 1989 <a href="https://www.ecowatch.com/tag/basel-convention" target="_self">Basel Convention</a>, which governs trade in hazardous materials, <a href="https://www.ecowatch.com/plastic-pollution-agreement-2636986814.html" target="_self">to include plastic waste</a>. The historic treaty created a legally binding framework to make global trade in <a href="https://www.ecowatch.com/tag/plastics" target="_self">plastic</a> waste more transparent and better regulated, the UN Environment Program (UNEP) said in a <a href="https://www.unenvironment.org/news-and-stories/press-release/governments-agree-landmark-decisions-protect-people-and-planet" target="_blank">press release</a>.</p><p>The amendment to the Basel Convention, which went into effect on Jan. 1, 2021, will result in a cleaner ocean within five years and allow developing nations like Vietnam and Malaysia to refuse low-quality and difficult-to-recycle waste before it ever gets shipped, a UN transboundary waste chief told <a href="https://www.theguardian.com/environment/2020/dec/29/new-rules-to-tackle-wild-west-of-plastic-waste-dumped-on-poorer-countries" target="_blank">The Guardian</a>.</p><p>"It is my optimistic view that, in five years, we will see results," Rolph Payet, the executive director of the Basel Convention, told The Guardian. "People on the frontline are going to be telling us whether there is a decrease of plastic in the ocean. I don't see that happening in the next two to three years, but on the horizon of five years. This amendment is just the beginning."</p><p>"Pollution from <a href="https://www.ecowatch.com/tag/plastic-waste" target="_self">plastic waste</a>, acknowledged as a major environmental problem of global concern, has reached epidemic proportions with an estimated 100 million tons of plastic now found in the oceans, 80-90 percent of which comes from land-based sources," the UNEP release noted, explaining a primary rationale behind the amendment's passage.</p><p>Once in the oceans, plastic continues to cause harm. It degrades into <a href="https://www.ecowatch.com/tag/microplastics" target="_self">microplastics</a>, which <a href="https://www.ecowatch.com/seafood-study-plastic-contamination-2646982206.html" target="_self">end up in our seafood</a> and <a href="https://www.ecowatch.com/microplastics-found-human-organs-2647014349.html#:~:text=According%20to%20PlasticsEurope.org%2C%20359,74%2C000%20microplastic%20particles%20a%20year." target="_self">ultimately us</a>. A recent study also found that <a href="https://www.ecowatch.com/ocean-acidification-plastic-polllution-2648847023.html" target="_self">plastic pollution increases ocean acidification</a>.</p>
<p>The amendment now requires "prior notice and consent" in writing from importing and transit countries before shipping plastic waste for recycling, the <a href="http://requirements/" target="_blank">Environmental Protection Agency (EPA)</a> explained. Exporting countries must detail whether a shipment is mixed or contaminated. If permission isn't granted to receive the goods, they must remain in their country of origin.</p><p>The new international rule aims to level the playing field between wealthy nations that dump contaminated plastic waste and poorer ones that have traditionally received it. According to The Guardian, before the new rule, shipments containing contaminated, non-recyclable and low-quality plastics were often sold to developing nations for recycling. After China refused to continue accepting contaminated waste in 2018, the onus fell on other developing nations to accept it, a 2020 <a href="https://www.greenpeace.org/international/press-release/43469/waste-trade-woes-plastic-waste-from-developed-countries-add-to-malaysias-environmental-crisis/" target="_blank">Greenpeace report </a>found. Once received, the waste was often illegally burned or dumped in landfills and waterways because it was unusable and unrecyclable.</p><p>Heng Kiah Chun, a Greenpeace Malaysia campaigner, called the impact from illegally dumping plastic waste from more than 19 countries worldwide "an indelible mark" left throughout Southeast Asia, the report added.</p><p>According to the EPA, the Basel Convention made an exception for pre-sorted, clean, uncontaminated and recycling-bound plastic scrap: it will not be subject to informed consent requirements. The idea is to encourage exports of commercially viable plastics for recycling rather than the unrestricted dumping of plastic trash that previously occurred.</p><p>In Dec. 2020, the European Union passed <a href="https://www.ecowatch.com/eu-bans-plastic-waste-exports-2649639389.html" target="_self">additional regulations</a> that are even stricter than the Basel Convention amendment, including a ban on sending unsorted plastic waste, which is harder to recycle, to poorer countries. </p>
<p>Despite <a href="https://www.ecowatch.com/world-plastic-waste-leader-us-2648607158.html" target="_self">leading the world in plastic waste</a>, the U.S. did not agree to the amendment in 2019. However, the amendment still applies to the U.S. anytime it tries to trade plastic waste with another of the 187 participating countries, <a href="https://www.cnn.com/2019/05/11/world/basel-convention-plastic-waste-trade-intl/index.html" target="_blank">CNN</a> reported.</p><p>Rather than framing the plastic problem as an issue between developed and developing nations, some critics would rather see <a href="https://www.ecowatch.com/plastic-pollution-producer-responsibility-2649792843.html" target="_self">commercial producers take responsibility</a>. Others, noting that <a href="https://www.ecowatch.com/plastic-recycling-myth-2647706452.html?rebelltitem=1#rebelltitem1" target="_self">recycling</a> models, especially in the U.S., aren't working, are encouraging a cultural shift away from using plastics, stemming the problem of plastic pollution at the source.</p><p>Nevertheless, the convention is a "crucial first step towards stopping the use of developing countries as a dumping ground for the world's plastic waste, especially those coming from rich nations," Von Hernandez, Break Free From Plastic global coordinator, told CNN.</p><p>"Countries at the receiving end of mixed and unsorted plastic waste from foreign sources now have the right to refuse these problematic shipments, in turn compelling source countries to ensure exports of clean, recyclable plastics only," Hernandez added. "Recycling will not be enough, however. Ultimately, production of plastics has to be significantly curtailed to effectively resolve the plastic pollution crisis."</p>

Reindeers at their winter location in northern Sweden on Feb. 4, 2020, near Ornskoldsvik. JONATHAN NACKSTRAND / AFP via Getty Images
Sweden's reindeer have a problem. In winter, they feed on lichens buried beneath the snow. But the climate crisis is making this difficult. Warmer temperatures mean moisture sometimes falls as rain instead of snow. When the air refreezes, a layer of ice forms between the reindeer and their meal, forcing them to wander further in search of ideal conditions. And sometimes, this means crossing busy roads.
<p>Luckily, Sweden's transport authorities have a solution. They are planning to build a dozen bridges in northern Sweden so that the reindeer can cross in peace, Swedish public science radio <a href="https://sverigesradio.se/artikel/7649066" target="_blank">Vetenskapsradion reported Monday</a>, according to <a href="https://www.thelocal.se/20210119/sweden-to-build-reindeer-bridges-so-they-can-cross-roads-to-find-food" target="_blank">The Local Sweden</a>.</p><p>"In a changing climate with difficult snow conditions, it will be extra important to be able to find and access alternative pastures," Swedish University of Agricultural Sciences landscape ecologist Per Sandström told the radio, as <a href="https://www.theguardian.com/world/2021/jan/20/sweden-to-build-bridges-for-reindeer-to-safely-cross-roads-and-railways?CMP=fb_gu&utm_medium=Social&utm_source=Facebook&fbclid=IwAR2nkVyCQKM6c-SKoghZwJbXw0zrgKjcJhjkh9KqZkd1utAWq1LFzaBTveU#Echobox=1611148969" target="_blank">The Guardian translated</a>.</p><p>The new bridges will be called "renoducts," a combination of the Swedish word for reindeer (ren) and viaduct.</p>
<p><a href="https://www.ecowatch.com/tag/wildlife" target="_self">Wildlife</a> bridges are an effective solution to the problem of helping animals to travel through a world criss-crossed by highways. The <a href="https://www.ecowatch.com/san-antonio-wildlife-bridge-2649485994.html" target="_self">first</a> was constructed in France in the 1950s, and they can significantly reduce collisions between animals and vehicles.</p><p>Work will begin this year on the first of the Swedish renoducts over the E4 motorway north of the city of Umeå, Vetenskapsradion reported. This motorway now has to be shut down entirely every time a herd attempts to cross.</p><p>The renoducts aren't only a boon for Sweden's 250,000 reindeer. They are also a help to the 4,500 Indigenous Sami who have special authorization to herd them, The Guardian explained.</p>
<p>The changing climate has driven up costs and extended the time it takes to herd the reindeer, according to an AFP story published in <a href="https://www.thelocal.se/20200529/how-swedens-sami-reindeer-herders-are-being-forced-to-adapt-to-climate-change" rel="noopener noreferrer" target="_blank">The Local Sweden in May 2020</a>. Sami couple Margret Fjellstrom and Daniel Viklund told AFP that it took them twice as long to move their reindeer from their summer to winter pastures last year than it would have under regular weather conditions.</p><p>"It can rain in January, it can snow in May, there's no logic to it any more," Fjellstrom told AFP.</p><p>Sami herders hope the new renoducts will help.</p><p>"I'm looking forward to us being able to cross undisturbed," reindeer herder Tobias Jonsson told Vetenskapsradion, as The Guardian translated.</p><p>He said that herders had helped with the design of the renoducts so that the reindeer would be more likely to use them. They recommended two meter (approximately seven foot) barriers so that the reindeer would not fall off but insisted that the bridges be open on top so that the reindeer would not be too frightened to cross.</p><p>Sweden's reindeer aren't the only ones in trouble because of climate change. A <a href="https://www.ecowatch.com/reindeer-population-climate-change-2623281571.html" target="_self">2018 report</a> found that reindeer and caribou numbers across the Arctic had fallen by 56 percent in the preceding two decades.</p>

The Great Lakes, including Lake Michigan, experienced some of their warmest temperatures on record in the summer of 2020. Ken Ilio / Moment / Getty Images
Heatwaves are not just distinct to the land. A recent study found lakes are susceptible to temperature rise too, causing "lake heatwaves," The Independent reported.
<p>For the first time, researchers showed how lakes experience <a href="http://www.ecowatch.com/tag/heat-wave" target="_self">heatwaves</a> and are sensitive to variations in the climate, lead author Dr. Iestyn Woolway, a research fellow at the European Space Agency's Climate Office in the UK, told The Independent.</p><p>Published on Wednesday in Nature, the study analyzed how hundreds of lake temperatures changed across the world, from the period between 1901 to 2099. If greenhouse gas emissions continue to rise, lakes will experience hotter and longer heatwaves, researchers <a href="https://www.nature.com/articles/s41586-020-03119-1" target="_blank">found.</a></p>
<p>Woolway and his team studied lake temperatures during heatwaves under two scenarios: high greenhouse gas emissions and low greenhouse gas emissions. Compared to data from the period between 1970-1999, the average temperature of global lakes could increase to about 1.7°C during heatwaves by the end of the century in a high greenhouse gas emission future, <a href="https://www.independent.co.uk/environment/climate-change/climate-crisis-lake-heatwaves-lethal-b1790076.html" target="_blank">The Independent reported.</a></p><p>But high greenhouse gas emissions could increase more than just a lake's temperature during a heatwave. The average length of a heatwave could also increase from eight days to 95 days by the end of the century, The Independent reported.</p><p>"As lakes warm during the twenty-first century, their heatwaves will begin to extend across multiple seasons, with some lakes reaching a permanent heatwave state," <a href="https://www.nature.com/articles/s41586-020-03119-1" target="_blank" rel="noopener noreferrer">the study noted</a>.</p>
<p>Over the summer, the Great Lakes experienced some of their warmest temperatures on record. Surface water temperature in all the Great Lakes, except for Lake Superior, experienced temperatures in the 70s, <a href="https://www.washingtonpost.com/weather/2020/07/14/great-lakes-record-warm-water/" target="_blank">The Washington Post</a> reported in July. Lake Erie even reported temperatures in the 80s, similar to that of Virginia Beach.</p><p>"Ultimately, lake temperatures follow the temperatures of the atmosphere," Dr. Woolway told The Independent.</p><p>The Great Lakes water temperatures were six to eleven degrees warmer than normal this past summer, responding to air temperatures in the region that were some of the warmest ever reported, The Washington Post reported.</p><p>"Last year was really cold and there was a lot of rain. This year there hasn't been as much rain, and it's been persistently hot," Andrea Vander Woude, manager of the Great Lakes CoastWatch program at NOAA, told The Washington Post.</p>
<p>Some locals in the Great Lake region had nothing to complain about. "I'm loving this," Whitney Miller, a Michigan-based swim instructor, told the Record-Eagle, a newspaper in the region, according to The Washington Post. "Last year I was in a wetsuit up through the 15th of July ... I was a popsicle." However, high temperatures in lakes pose a serious threat to the survival of natural ecosystems, the study found.</p><p>Serving as more than just a recreational hotspot, the Great Lakes are an important source for clean water and economic livelihood. Nearly 90 percent of the freshwater in the United States and approximately 20 percent of the world's fresh water supply comes from the Great Lakes, <a href="https://www.noaa.gov/education/resource-collections/freshwater/great-lakes-ecoregion#:~:text=Lawrence%20Seaway.,system%20for%20clean%20drinking%20water" target="_blank">according to NOAA</a>. Millions of pounds of fish are also extracted out of the lakes each year.</p><p>Increases in water temperature will reduce habitat for coldwater fish, making the lakes more suitable habitats for invasive species and susceptible to dangerous algal blooms, <a href="https://www.nwf.org/Educational-Resources/Wildlife-Guide/Wild-Places/Great-Lakes" target="_blank" rel="noopener noreferrer">The National Wildlife Federation reported</a>.</p><p>But meeting the <a href="https://www.ecowatch.com/tag/paris-agreement">Paris agreement'</a>s goal of limiting global warming below 2°C compared to pre-industrial levels could slow temperature increases and reduce heatwave length in lakes, the study found.</p>
<p>Relative to the period between 1970 and 1999, lake temperatures during heatwaves could be limited to just a 0.3°C increase by the end of the century if this goal is met. A lake's heatwave duration could also be limited, increasing by only 27 days, rather than 95 days in a high emissions future, according to the study.</p><p>To avoid major changes to lake ecosystems, action must be taken now, the researchers stress. "Reducing greenhouse gas emissions must remain at the forefront of our agenda," Dr. Woolway told The Independent. </p>
