Meet the Man Who Said: Clean Energy Policies Are a Greater Threat Than Terrorism
By Dave Anderson
Travis Fisher, a Trump political appointee in the Department of Energy, wrote a 2015 report for the Institute for Energy Research that called clean energy policies "the single greatest emerging threat" to the nation's electric power grid, and a greater threat to electric reliability than cyber attacks, terrorism or extreme weather.
Fisher is now leading up a controversial grid study ordered by Sec. of Energy Rick Perry under the pretense of ensuring the long-term reliability of the nation's electricity supply. If Fisher's past writings on the topic are any indication, the forthcoming DOE study is sure to be a thinly veiled attack on renewable energy aimed at propping up outdated coal and nuclear power plants that can't compete in today's electricity market.
Rick Perry's grid study sounds strikingly similar to the one Travis Fisher wrote for fossil fuel interests in 2015.
Trump's Koch-Funded Appointees Continue Ruthless Attack on Clean Energy Growth https://t.co/4NsyZRlOqW @ALECExposed @prwatch— EcoWatch (@EcoWatch)1495316707.0
In his February 2015 report for the Institute for Energy Research (IER), Fisher attacked wind and solar power as "unreliable" sources of electricity. That same year, IER and its lobbying arm, the American Energy Alliance (AEA), together received millions of dollars from foundations affiliated with the Koch brothers, who have bankrolled an all out campaign to roll back state and federal clean energy policies.
In a 2016 bankruptcy filing, coal producer Peabody Energy also disclosed that it contributed $50,000 to IER in 2015. Fisher wrote in his 2015 IER report:
"The single greatest threat to reliable electricity in the U.S. does not come from natural disturbances or human attacks. Rather, the host of bad policies now coming from the federal government—and unfortunately from many state governments—is creating far greater and more predictable problems with grid reliability."
He also offered this overview:
"New stresses on the electricity delivery system are coming primarily from two types of policies: 1) Regulations that directly shut down reliable sources of electricity, such as coal and nuclear power, and 2) Subsidies and mandates that force increased amounts of unreliable sources of electricity on the grid, such as wind and solar power, and undermine the normal operation of reliable power plants. Together, these two types of policies create a much less reliable grid and increase the chances of a major blackout."
A strikingly similar narrative appeared in the memorandum from Perry, who also serves on President Trump's National Security Council, which ordered a new DOE study on grid reliability be prepared in just 60 days:
"Baseload power is necessary to a well-functioning electric grid. We are blessed as a nation to have an abundance of domestic energy resources, such as coal, natural gas, nuclear and hydroelectric, all of which provide affordable base load power and contribute to a stable, reliable and resilient grid. Over the last few years, however, grid experts have expressed concerns about the erosion of critical baseload resources.
Specifically, many have questioned the manner in which baseload power is dispatched and compensated. Still others have highlighted the diminishing diversity of our nation's electric generation mix, and what that could mean for baseload power and grid resilience. This has resulted in part from regulatory burdens introduced by previous administrations that were designed to decrease coal-fired power generation. Such policies have destroyed jobs and economic growth, and they threaten to undercut the performance of the grid well into the future.
Finally, analysts have thoroughly documented the market-distorting effects of federal subsidies that boost one form of energy at the expense of others. Those subsidies create acute and chronic problems for maintaining adequate baseload generation and have impacted reliable generators of all types."
Perry's memorandum included a specific order to examine, "The extent to which continued regulatory burdens, as well as mandates and tax and subsidy policies, are responsible for forcing the premature retirement of baseload power plants." Perry's words since his memorandum serve as a further reminder of the undue influence of IER and AEA over the Trump administration's energy policies, made possible by AEA's loyal support for Donald Trump during the 2016 election. Perry recently revealed the Trump administration's half-baked and "highly classified" plan to preempt state and local energy policies in the name of national security.
Travis Fisher targeted state and federal clean energy policies for repeal
The clean energy policies that Fisher targeted for repeal in his 2015 study for IER provide some clues about the possible identity of the "mandates and tax and subsidy policies" to which Perry made vague reference in his memo. These included a mix of state and federal policies designed to increase the use of renewable energy, as well as reduce carbon dioxide and mercury emissions from coal-fired power plants. Fisher specifically recommended that policymakers repeal:
• The Environmental Protection Agency's Clean Power Plan and Mercury and Air Toxics Standards
• The federal Production Tax Credit for wind power
• State renewable energy standards
• Net metering incentives for rooftop solarThese are the sort of clean energy policies that have long been targeted for repeal by IER and AEA and their backers in the fossil fuel industry. Beyond Capitol Hill, a similar study with DOE's stamp could reignite failed attacks against renewable energy policies in states like Ohio, where IER and AEA's misleading reports have failed the smell test.
Fisher also referenced "bureaucratic hurdles" at the Nuclear Regulatory Commission, which he claimed has contributed to closure of "reliable" nuclear power plants. He pointed to the NRC as a factor in the closing of the Vermont Yankee nuclear power plant, but failed to mention the plant had been plagued by problems in recent years, including a cooling tower collapse and radioactive tritium leak.
Despite all the doomsday scenarios of electricity blackouts thrown into Travis Fisher's 2015 grid study for IER, he never named a single example where one of these clean energy policies actually caused the lights to go out. Most of these policies had been on the books for years, without causing the sorts of blackouts that Fisher predicted for the near future. Real world experience has proven beyond any reasonable doubt that grid operators and utilities can comply with clean energy policies, while also providing a reliable supply of electricity.
After all, a total of 29 states have renewable energy standards and 39 states have net metering on the books. The Production Tax Credit for wind power has been around since 1992. Utilities have already been complying with the EPA's Mercury and Air Toxics Standard. During the 1970's, electric utilities like American Electric Power ran ads that made the same sort of "doomsday predictions" about the Clean Air Act. In February 2015, the EPA responded to similar attacks on the Clean Power Plan by pointing out that "at no time in the more than 40 years that EPA has been implementing the Clean Air Act has compliance with air pollution standards resulted in reliability problems."
Fisher should heed his own advice
"Heed the advice of grid experts, such as the electrical engineers at NERC, FERC, utilities and regional transmission organizations," Fisher recommended at the end of his 2015 study for IER. What the grid gurus have told us over and over again is that renewable energy is reliable, and we can use much more of it in the years to come using the tools and technologies that are available today. Plus, clean energy policies generate cleaner electricity and a host of co-benefits. For example, previous analyses of state renewable energy standards by two of DOE's national labs have powered new jobs and reduced carbon dioxide and other harmful air pollutants, all at little to no additional cost to consumers. Rick Perry has praised those labs as national scientific and engineering treasures.
Travis Fisher downplayed real threats to the power grid
"Extreme weather places immense stress on the electricity system," Fisher admitted in his 2015 grid study for IER. "In fact, bad weather remains the number one cause of power outages." Fisher's own words exposed his all-too-obvious attempt to mischaracterize clean energy policies as "the single greatest threat to reliable electricity," as he put it.
Meanwhile, DOE published a 2015 report that identified the ways that extreme weather and climate change threaten reliable electricity in every region of the U.S. A total of 8.5 million people lost power during 2012's Hurricane Sandy. The impact of that storm was strengthened by climate change. Long lines formed at gas stations as people sought fuel to power backup generators. Yet Fisher made no mention of Hurricane Sandy in his 2015 IER study. In fact, he avoided any mention of the threat that climate change poses to the electric grid. He instead focused on his attacks on the Clean Power Plan, which set the first-ever national limits on carbon dioxide emissions from power plants that contribute to climate change.
Fisher even mixed in the sort of rhetoric common among the network of fossil fuel funded climate skeptics that IER and AEA are a part of. "The problem with calling it the 'Clean Power Plan' is that carbon dioxide is not dirty but rather a clean, odorless gas," Fisher wrote. To his credit, Fisher did mention that coal and natural gas can face challenges during periods of extreme cold. He focused on how the Polar Vortex disrupted the natural gas market as demand spiked. However, like many coal backers, Fisher either missed or ignored the fact that coal-fired power plants accounted for 26 percentage of outages in the ERCOT and Eastern Interconnections. He also neglected to mention that record wind power had saved electric utility customers money during recent periods of extreme cold.
Fisher also downplayed the threat posed by cyber, electromagnetic pulse, or terrorist attacks on the nation's power supply. He suggested the threat of U.S. retaliation served as an effective deterrent effect against attacks on the nation's power grid. He acknowledged one real world example in San Jose, where quick action by the local utility averted a blackout after a 2014 sniper attack on a power substation.
However, Fisher ignored the 9/11 terrorist attacks of 2011. While terrorists' primary target in New York was the World Trade Center, the attack also knocked out power to Lower Manhattan and destroyed two power substations. More than 2,000 Con Edison employees eventually restored power after they laid down 36 miles of emergency cable to bring electricity back to the impacted area. Initial estimates by Con Edison put the cost of repairs at $400 million. Fisher didn't deny that extreme weather and "human attacks," as he called them, posed significant threats, but he did mischaracterize clean energy policies as an even greater threat to the power grid.
Travis Fisher supported new infrastructure to benefit fossil fuels, but not for renewable energy
The 2015 grid study that Fisher wrote for IER also included support for escalating new oil and gas pipelines by overcoming what he described as "permitting delays" at the Federal Energy Regulatory Commission (FERC) and at the state level. Many environmentalists view FERC as a "rubber stamp" for pipelines, a concern that's only increased since President Trump named his nominees to the commission. Fisher even threw in a pitch for the Keystone XL pipeline, even though oil provides less than one percent of U.S. electricity.
He claimed that reliance on railroads to move tar sands oil meant that less rail capacity was available to transport coal and other things. Fisher wrote that use of fossil fuels was limited by a lack of infrastructure, and he was happy to spend other people's money to fix it. Not so for renewable energy. Fisher argued that the grid should not be updated to integrate more wind and solar power. "In other words, the incompatibility of wind and solar power on the grid is not a major drawback of the grid," Fisher said. "Rather, it is a major drawback of these sources of power." Fisher encouraged government to engage in the very behavior that he and his "free market" allies in the Koch world routinely disparage: picking winners and losers in the energy market.
Travis Fisher is loyal to fossil fuel interests and powerful political donors
Travis Fisher is the subject of one edition of the John William Pope Foundation's "achiever spotlight," which highlights "the lives of individuals who have achieved much, thanks in large part to the generosity of nonprofits and organizations supported by the Foundation." The foundation is led by Art Pope, a financier of right wing causes who plays an outsized role in North Carolina politics. Among the causes Pope has funded: climate denial and attacks on clean energy policies. As a college student at North Carolina State University in 2006, Travis Fisher was enrolled in the school's program on Economic, Legal and Political Foundations of Free Economies, a beneficiary of Pope's largesse. He was also a research intern at the John Locke Foundation, which was launched by Pope during the 1990s and has received money from the Koch brothers, where he worked on "policy alternatives" on issues that included the environment.
The group would later use Fisher's work for IER and AEA to support its attacks on North Carolina's renewable energy standard. After college, Fisher landed a job as an economist at FERC during the summer of 2006. After seven years at the commission, he decided to take a job at IER in 2013. Fisher later shared his thinking on energy policy with the John William Pope Foundation.
"It seems conventional wisdom that government should get more involved in energy," Fisher said in his achiever spotlight on JWPF.org. "It's counter intuitive [sic] to argue that government should get out of energy. But I like the challenge."
Who paid for Travis Fisher to serve on Trump's Department of Energy landing team?
A list of landing team members on GreatAgain.gov, the Trump transition team's website, disclosed Fisher's "current or most recent employer" as IER, but did not list AEA—even though Fisher is listed as an "IER economist" and "AEA economist" on the groups' respective websites. The transition team website also listed "funding source: private" for Fisher, while some other landing team members were identified as volunteers. The site did not disclose the private source of Fisher's funding.
A separate financial disclosure filed by Fisher and published by The Intercept also disclosed his employment by IER, but not AEA. He also disclosed "Employment Assets and Retirement Plans," which included his IER salary and related 401K, as well as his participation in the "Charles Koch Industries 401K." In a section below titled, "Filer Employer Agreements and Arrangement," Fisher disclosed to continue to participate in both 401K plans, but specified that both IER and the "Charles Koch Institute" would no longer make contributions. A Google search revealed no previous record of Fisher's employment with the Charles Koch Institute.
Just the latest sign of IER, AEA influence over Trump
It's no coincidence that, now that Donald Trump is in the White House, some of the same clean energy policies that Fisher targeted for attack in his 2015 grid study for IER are now being rolled back. As a candidate, Donald Trump was one of only two Republicans who responded to an AEA questionnaire. In his response to a question about the Clean Power Plan, Trump pledged that "all EPA rules will be reviewed." Trump also pledged to rescind the Clean Power Plan while in the campaign trail.
During the Trump transition, an IER-AEA memo from the desk of Tom Pyle, which was obtained by the Center for Media & Democracy, predicted that the Clean Power Plan would be withdrawn by the Trump administration—even if courts upheld the rule. Pyle, IER and AEA soon got their wish. Trump signed an executive order that began the process of reviewing the Clean Power Plan during his first 100 days in the White House. His administration also hit the pause button on the EPA's legal efforts to defend the Mercury and Air Toxics Standards, another target of Fisher's 2015 IER report, in court.
With Fisher at the helm, the DOE grid study ordered by Rick Perry could serve as a convenient excuse when the Trump administration's "review" of the Clean Power Plan culminates in a real plan to "suspend, revise or rescind" the rule. It could also be used to justify attempts by the Trump administration to preempt state and local clean energy laws, though any such effort would face an uphill battle. Finally, the new DOE grid study could be used to reignite efforts to rollback renewable energy standards and net metering incentives at the state level. In any case, clean energy supporters will have no shortage of evidence at the ready to debunk any erroneous claims made by Fisher, and make the case that renewable energy is affordable, reliable and benefits our economy and the environment.

A key part of the United States' clean energy transition has started to take shape, but you may need to squint to see it. About 2,000 wind turbines could be built far offshore, in federal waters off the Atlantic Coast, in the next 10 years. And more are expected.
Threats to Birds<p>One of the gravest threats facing birds is climate change, according to Audubon, which found that rising temperatures threaten <a href="https://www.audubon.org/2019climateissue" target="_blank" rel="noopener noreferrer">nearly two-thirds of North America's bird species</a>. That's why the impending development of offshore wind is a good thing, says Shilo Felton, a field manager in the organization's Clean Energy Initiative, but it also comes with dangers to birds that need to be better studied and mitigated.</p><p>The most obvious risk comes from birds colliding with spinning turbine blades. But offshore wind developments can also displace birds from foraging or roost sites, as well as migratory pathways.</p><p>Along the Atlantic Coast four imperiled species are of top concern to conservationists: the endangered piping plover, red knot, roseate tern and black-capped petrel, which is being considered for listing under the Endangered Species Act.</p><p>"Those four species are of utmost importance to make sure that we understand the impacts," says Felton. "But beyond that there are many species that are protected under the Migratory Bird Treaty Act and the Fish and Wildlife Conservation Act that could potentially see more impacts from offshore wind."</p><p>Northern gannets, for example, are at risk not just for collision but <a href="https://www.researchgate.net/publication/308703197_Possible_impacts_of_offshore_wind_farms_on_seabirds_a_pilot_study_in_Northern_Gannets_in_the_southern_North_Sea" target="_blank">habitat displacement</a>.</p>

Researchers are still studying what this may mean for the birds. But a <a href="https://www.sciencedirect.com/science/article/pii/S0141113620305304" target="_blank">study</a> published in December 2020 conducted at Bass Rock, Scotland — home to the world's largest northern gannet colony — found that wind developments could reduce their growth rate, though not enough to cause a population decline.</p><p>Other birds, such as great cormorants and European shags, are <a href="https://www.sciencedirect.com/science/article/abs/pii/S0006320716303196" target="_blank">attracted to wind developments</a> and use the infrastructure to rest while opening up new foraging areas farther from shore.</p><p>"There's plenty of potential for a bird to use a wind farm and still to avoid the turbines themselves," says Felton.</p><p>Birds like pelicans, however, are less versatile in their movements and are at particular risk of collision because of their flight pattern, she says.</p><p>But how disruptive or dangerous offshore turbines will be along the East Coast isn't yet known.</p><p>Federal and state agencies, along with nongovernmental organizations, says Felton, have done good research to try to better understand those potential impacts. "But these are all theoretical, because we don't have a lot of offshore wind yet in the United States."</p>
Threats to Ocean Life<p>Birds aren't the only wildlife of concern. More development in ocean waters could affect a litany of marine species, some of which are already facing other pressures from overfishing, pollution, habitat destruction and climate change.</p><p>Scientists have found that marine mammals like whales and dolphins could be disturbed by the jarring sounds of construction, especially if pile driving is used to hammer the steel turbine platform into the seafloor.</p><p>The noises, though short-lived, could impede communication between animals, divert them from migration routes or cause them to seek less suitable areas for feeding or breeding. Research from Europe found that harbor porpoises, seals and dolphins may avoid development areas during construction. In most, but <a href="https://iopscience.iop.org/article/10.1088/1748-9326/7/4/045101" target="_blank">not all cases</a>, the animals were believed to have returned to the area following construction.</p><p>The biggest concern for conservation groups in the United States is the critically endangered North American right whale. There are fewer than 400 remaining, and the species' habitat overlaps with a number of planned wind development areas along the East Coast.</p><p>"Offshore wind is in no way the cause of the challenges the whales face, but it's going to be another pressure point," says John Rogers, senior energy analyst for the Union of Concerned Scientists.</p><p>Researchers aren't sure how right whales will respond to the noise from pile driving.</p><p>"But we are concerned, based on what we know about how whales react to other noise sources, that they may avoid [wind development] areas," says Kershaw.</p><p>And if that displacement causes them to miss out on important food resources, it could be dangerous for a species already on the brink.</p><p>There are a few other potential threats, too.</p><p>Ships associated with the development — more plentiful during construction — also pose a danger. In the past few years cargo ships, fishing boats and other vessels have caused half of all deaths of North Atlantic right whales.</p>
A juvenile right whale breaches against the backdrop of a ship near the St. Johns River entrance. Florida Fish and Wildlife Conservation Commission / NOAA Research Permit #775-1600-10<p>And after construction, the noise from the spinning turbines will be present in the water at low decibels. "We don't quite know how the great whales will react to those sounds," says Jeremy Firestone, the director of the Center for Research in Wind at the University of Delaware.</p><p>Other marine mammals may also perceive the noise, but at low decibels it's unlikely to be an impediment, <a href="http://www.int-res.com/abstracts/meps/v309/p279-295/" target="_blank">research has found</a>.</p><p>And it's possible that wind development could help some ocean life. Turbine foundations can attract fish and invertebrates for whom hard substrates create habitat complexity — known as the "reef effect," according to researchers from the University of Rhode Island's <a href="https://dosits.org/animals/effects-of-sound/anthropogenic-sources/wind-turbine/" target="_blank" rel="noopener noreferrer">Discovery of Sound in the Sea</a> program. Exclusion of commercial fishing nearby may also help shelter fish and protect marine mammals from entanglements in fishing gear.</p>
Ensuring Safe Development<p>Despite the potential dangers, researchers have gathered a few best practices to help diminish and possibly eliminate some risks.</p><p>When it comes to ship strikes, the easiest thing is to slow boats down, mandating a speed of <a href="https://biologicaldiversity.org/w/news/press-releases/vessel-speed-limits-sought-protect-endangered-north-atlantic-right-whales-2020-08-06/" target="_blank">10 knots</a> in wind development areas, and using visual and acoustic monitoring for whales.</p><p>Adjusting operations to reduce boat trips between the shore and the wind development will also help. A new series of service operating vessels can allow maintenance staff to spent multiple days onsite, says Kershaw, cutting down on boat traffic.</p><p>For construction noise concerns, developers can avoid pile driving during times of the year when whales are present. And, depending on the marine environment, developers could use "quiet foundations" that don't require pile driving. These include gravity-based or suction caisson platforms.</p><p>Floating turbines are also used in deep water, where they're effectively anchored in place — although that poses its own potential danger. "We have concerns that marine debris could potentially become entangled around the mooring cables of the floating arrays and pose a secondarily entanglement risk to some species," says Felton, who thinks more research should be conducted before those become operational in U.S. waters — a process that's already underway in Maine, where a <a href="https://composites.umaine.edu/2020/08/05/diamond-offshore-wind-rwe-renewables-join-the-university-of-maine-to-lead-development-of-maine-floating-offshore-wind-demonstration-project/" target="_blank" rel="noopener noreferrer">demonstration project is being built</a>.</p><p>If loud noises are unavoidable during construction, noise-reducing technologies such as bubble curtains can help dampen the sound. And scheduling adjacent projects to conduct similar work at the same time could limit the duration of disturbances.</p>

Vattenfall / Ulrich Wirrwa / CC BY-NC-ND 2.0<p>Once turbines become operational, reducing the amount of light on wind platforms or using flashing lights could help deter some seabirds, NRDC <a href="https://www.nrdc.org/sites/default/files/harnessing-wind-advance-wind-power-offshore-ib.pdf" target="_blank" rel="noopener noreferrer">researchers reported</a>. And scientists are exploring using ultrasonic noises and ultraviolet lighting to keep bats away. "Feathering," or shutting down the turbine blades during key migration times, could also help prevent fatalities.</p><p>"We need to make sure that offshore wind is the best steward it can be of the marine ecosystem, because we want and expect it to be a significant part of the clean energy picture in some parts of the country," says Rogers. "We also have to recognize that we're going to learn by doing, and that some of these things we're going to figure out best once we have more turbines in the water."</p><p>That's why environmental groups say it's important to establish baseline information on species before projects begin, and then require developers to conduct monitoring during construction and for years after projects are operational.</p><p>Employing an "adaptive management framework" will ensure that developers can adjust their management practices as they go when new information becomes available, and that those best practices are incorporated into the requirements for future projects.</p>
Putting Research Into Action<p>Advancing these conversations at the federal level during the Trump administration, though, has been slow going.</p><p>"We didn't really have any productive discussions with the administration in the last four years," says Kershaw.</p><p>And when it comes to birds, Felton says the Bureau of Ocean Energy Management's recently completed "draft cumulative environmental impact statement" covering offshore wind developments had a lot of good environmental research, but little focus on birds.</p><p>"Part of that comes from the current administration's interpretation of the Migratory Bird Treaty Act," she says.</p><p>President Trump has been hostile to both wind energy <em>and</em> birds, <a href="https://www.nytimes.com/2021/01/05/climate/trump-migratory-bird-protections.html" target="_blank">and finished gutting the Migratory Bird Treaty Act</a> in his administration's the final days, removing penalties for companies whose operations kill migratory birds.</p><p>There's hope that the Biden administration will take a different approach. But where the federal government has been lacking lately, Kershaw says, they've seen states step up.</p><p>New York, for example, has established an <a href="https://www.nyetwg.com/" target="_blank" rel="noopener noreferrer">Environmental Technical Working Group</a> composed of stakeholders to advise on environmentally responsible development of offshore wind.</p><p>The group is led by the New York State Energy Research and Development Authority, but it isn't limited to the Empire State. It's regional in focus and includes representatives from wind developers with leases between Massachusetts and North Carolina; state agencies from Massachusetts to Virginia; federal agencies; and science-based environmental NGOs.</p><p>New York's latest solicitation for clean energy projects includes up to 2,500 megawatts of offshore wind and <a href="https://www.nyetwg.com/announcements" target="_blank" rel="noopener noreferrer">requires developers</a> to contribute at least $10,000 per megawatt for regional monitoring of fisheries and other wildlife.</p><p>Environmental groups have also worked directly with developers, including an agreement with Vineyard Wind — an 800-megawatt project off the Massachusetts coast that could be the first utility-scale wind development in federal waters — to help protect North Atlantic right whales.</p><p>The agreement includes no pile driving from Jan. 1 to April 30, ceasing activities at other times when whales are visually or acoustically identified in the area, speed restrictions on vessels, and the use of noise reduction technology, such as a bubble curtain during pile driving.</p><p>"The developers signed the agreement with us, and then they incorporated, most, if not all of those measures into the federal permitting documents," says Kershaw. "The developers really did a lot of bottom up work to make sure that they were being very protective of right whales."</p><p>Environmental groups are in talks with other developers on agreements too, but Felton wants to see best practices being mandated at the federal level.</p><p>"It's the sort of a role that should be being played by the federal government, and without that it makes the permitting and regulation process less stable and less transparent," she says." And that in turn slows down the build out of projects, which is also bad for birds because it doesn't help us address and mitigate for climate change."</p><p>Kershaw agrees there's a lot more work to be done, especially at the federal level, but thinks we're moving in the right direction.</p><p>"I think the work that's been done so far in the United States has really laid the groundwork for advancing this in the right way and in a way that's protective of species and the environment," she says. "At the same time, it's important that offshore wind does advance quickly. We really need it to help us combat the worst effects of climate change."</p><p><em><a href="https://therevelator.org/author/taralohan/" target="_blank" rel="noopener noreferrer">Tara Lohan</a> is deputy editor of The Revelator and has worked for more than a decade as a digital editor and environmental journalist focused on the intersections of energy, water and climate.

Millions of birds travel between their breeding and wintering grounds during spring and autumn migration, creating one of the greatest spectacles of the natural world. These journeys often span incredible distances. For example, the Blackpoll warbler, which weighs less than half an ounce, may travel up to 1,500 miles between its nesting grounds in Canada and its wintering grounds in the Caribbean and South America.
Blackpoll warbler. PJTurgeon / Wikipedia<p>We used this information to determine how the number of migratory bird species varies based on each city's level of <a href="https://www.britannica.com/science/light-pollution" target="_blank" rel="noopener noreferrer">light pollution</a> – brightening of the night sky caused by artificial light sources, such as buildings and streetlights. We also explored how species numbers vary based on the quantity of tree canopy cover and impervious surface, such as concrete and asphalt, within each city. Our findings show that cities can help migrating birds by planting more trees and reducing light pollution, especially during spring and autumn migration.</p>
Declining Bird Populations<p>Urban areas contain numerous dangers for migratory birds. The biggest threat is the risk of <a href="https://doi.org/10.1650/CONDOR-13-090.1" target="_blank">colliding with buildings or communication towers</a>. Many migratory bird populations have <a href="http://dx.doi.org/10.1126/science.aaw1313" target="_blank">declined over the past 50 years</a>, and it is possible that light pollution from cities is contributing to these losses.</p><p>Scientists widely agree that light pollution can <a href="https://doi.org/10.1073/pnas.1708574114" target="_blank">severely disorient migratory birds</a> and make it hard for them to navigate. Studies have shown that birds will cluster around brightly lit structures, much like insects flying around a porch light at night.

The Power of Citizen Science<p>It's not easy to observe and document bird migration, especially for species that migrate at night. The main challenge is that many of these species are very small, which limits scientists' ability to use electronic tracking devices.</p><p>With the growth of the internet and other information technologies, new data resources are becoming available that are making it possible to overcome some of these challenges. <a href="https://doi.org/10.1038/d41586-018-07106-5" target="_blank">Citizen science initiatives</a> in which volunteers use online portals to enter their observations of the natural world have become an important resource for researchers.</p><p>One such initiative, <a href="https://ebird.org/home" target="_blank" rel="noopener noreferrer">eBird</a>, allows bird-watchers around the globe to share their observations from any location and time. This has produced one of the <a href="https://doi.org/10.1111/ecog.04632" target="_blank" rel="noopener noreferrer">largest ecological citizen-science databases in the world</a>. To date, eBird contains over 922 million bird observations compiled by over 617,000 participants.</p>
Light Pollution Both Attracts and Repels Migratory Birds<p>Migratory bird species have evolved to use certain migration routes and types of habitat, such as forests, grasslands or marshes. While humans may enjoy seeing migratory birds appear in urban areas, it's generally not good for bird populations. In addition to the many hazards that exist in urban areas, cities typically lack the food resources and cover that birds need during migration or when raising their young. As scientists, we're concerned when we see evidence that migratory birds are being drawn away from their traditional migration routes and natural habitats.</p><p>Through our analysis of eBird data, we found that cities contained the greatest numbers of migratory bird species during spring and autumn migration. Higher levels of light pollution were associated with more species during migration – evidence that light pollution attracts migratory birds to cities across the U.S. This is cause for concern, as it shows that the influence of light pollution on migratory behavior is strong enough to increase the number of species that would normally be found in urban areas.</p><p>In contrast, we found that higher levels of light pollution were associated with fewer migratory bird species during the summer and winter. This is likely due to the scarcity of suitable habitat in cities, such as large forest patches, in combination with the adverse affects of light pollution on bird behavior and health. In addition, during these seasons, migratory birds are active only during the day and their populations are largely stationary, creating few opportunities for light pollution to attract them to urban areas.</p>
Trees and Pavement<p>We found that tree canopy cover was associated with more migratory bird species during spring migration and the summer. Trees provide important habitat for migratory birds during migration and the breeding season, so the presence of trees can have a strong effect on the number of migratory bird species that occur in cities.</p><p>Finally, we found that higher levels of impervious surface were associated with more migratory bird species during the winter. This result is somewhat surprising. It could be a product of the <a href="https://www.epa.gov/heatislands" target="_blank">urban heat island effect</a> – the fact that structures and paved surfaces in cities absorb and reemit more of the sun's heat than natural surfaces. Replacing vegetation with buildings, roads and parking lots can therefore make cities significantly warmer than surrounding lands. This effect could reduce cold stress on birds and increase food resources, such as insect populations, during the winter.</p><p>Our research adds to our understanding of how conditions in cities can both help and hurt migratory bird populations. We hope that our findings will inform urban planning initiatives and strategies to reduce the harmful effects of cities on migratory birds through such measures as <a href="https://www.arborday.org/programs/treecityusa/index.cfm" target="_blank" rel="noopener noreferrer">planting more trees</a> and initiating <a href="https://aeroecolab.com/uslights" target="_blank" rel="noopener noreferrer">lights-out programs</a>. Efforts to make it easier for migratory birds to complete their incredible journeys will help maintain their populations into the future.</p><p><em><span style="background-color: initial;"><a href="https://theconversation.com/profiles/frank-la-sorte-1191494" target="_blank">Frank La Sorte</a> is a r</span>esearch associate at the </em><em>Cornell Lab of Ornithology, Cornell University. <a href="https://theconversation.com/profiles/kyle-horton-1191498" target="_blank">Kyle Horton</a> is an assistant professor of Fish, Wildlife, and Conservation Biology at the Colorado State University.</em></p><p><em></em><em>Disclosure statement: Frank La Sorte receives funding from The Wolf Creek Charitable Foundation and the National Science Foundation (DBI-1939187).

Editor's note: This story is part of a nine-month investigation of drinking water contamination across the U.S. The series is supported by funding from the Park Foundation and Water Foundation. Read the launch story, "Thirsting for Solutions," here.
In late September 2020, officials in Wrangell, Alaska, warned residents who were elderly, pregnant or had health problems to avoid drinking the city's tap water — unless they could filter it on their own.
Unintended Consequences<p>Chemists first discovered disinfection by-products in treated drinking water in the 1970s. The trihalomethanes they found, they determined, had resulted from the reaction of chlorine with natural organic matter. Since then, scientists have identified more than 700 additional disinfection by-products. "And those only represent a portion. We still don't know half of them," says Richardson, whose lab has identified hundreds of disinfection by-products. </p>
What’s Regulated and What’s Not?<p>The U.S. Environmental Protection Agency (EPA) currently regulates 11 disinfection by-products — including a handful of trihalomethanes (THM) and haloacetic acids (HAA). While these represent only a small fraction of all disinfection by-products, EPA aims to use their presence to indicate the presence of other disinfection by-products. "The general idea is if you control THMs and HAAs, you implicitly or by default control everything else as well," says Korshin.</p><p>EPA also requires drinking water facilities to use techniques to reduce the concentration of organic materials before applying disinfectants, and regulates the quantity of disinfectants that systems use. These rules ultimately can help control levels of disinfection by-products in drinking water.</p>
Click the image for an interactive version of this chart on the Environmental Working Group website.<p>Still, some scientists and advocates argue that current regulations do not go far enough to protect the public. Many question whether the government is regulating the right disinfection by-products, and if water systems are doing enough to reduce disinfection by-products. EPA is now seeking public input as it considers potential revisions to regulations, including the possibility of regulating additional by-products. The agency held a <a href="https://www.epa.gov/dwsixyearreview/potential-revisions-microbial-and-disinfection-byproducts-rules" target="_blank">two-day public meeting</a> in October 2020 and plans to hold additional public meetings throughout 2021.</p><p>When EPA set regulations on disinfection by-products between the 1970s and early 2000s, the agency, as well as the scientific community, was primarily focused on by-products of reactions between organics and chlorine — historically the most common drinking water disinfectant. But the science has become increasingly clear that these chlorinated chemicals represent a fraction of the by-product problem.</p><p>For example, bromide or iodide can get caught up in the reaction, too. This is common where seawater penetrates a drinking water source. By itself, bromide is innocuous, says Korshin. "But it is extremely [reactive] with organics," he says. "As bromide levels increase with normal treatment, then concentrations of brominated disinfection by-products will increase quite rapidly."</p><p><a href="https://pubmed.ncbi.nlm.nih.gov/15487777/" target="_blank">Emerging</a> <a href="https://pubs.acs.org/doi/10.1021/acs.est.7b05440" target="_blank" rel="noopener noreferrer">data</a> indicate that brominated and iodinated by-products are potentially more harmful than the regulated by-products.</p><p>Almost half of the U.S. population lives within 50 miles of either the Atlantic or Pacific coasts, where saltwater intrusion can be a problem for drinking water supplies. "In the U.S., the rule of thumb is the closer to the sea, the more bromide you have," says Korshin, noting there are also places where bromide naturally leaches out from the soil. Still, some coastal areas tend to be spared. For example, the city of Seattle's water comes from the mountains, never making contact with seawater and tending to pick up minimal organic matter.</p><p>Hazardous disinfection by-products can also be an issue with desalination for drinking water. "As <a href="https://ensia.com/features/can-saltwater-quench-our-growing-thirst/" target="_blank" rel="noopener noreferrer">desalination</a> practices become more economical, then the issue of controlling bromide becomes quite important," adds Korshin.</p>
Other Hot Spots<p>Coastal areas represent just one type of hot spot for disinfection by-products. Agricultural regions tend to send organic matter — such as fertilizer and animal waste — into waterways. Areas with warmer climates generally have higher levels of natural organic matter. And nearly any urban area can be prone to stormwater runoff or combined sewer overflows, which can contain rainwater as well as untreated human waste, industrial wastewater, hazardous materials and organic debris. These events are especially common along the East Coast, notes Sydney Evans, a science analyst with the nonprofit Environmental Working Group (EWG, a collaborator on <a href="https://ensia.com/ensia-collections/troubled-waters/" target="_blank">this reporting project</a>).</p><p>The only drinking water sources that might be altogether free of disinfection by-products, suggests Richardson, are private wells that are not treated with disinfectants. She used to drink water from her own well. "It was always cold, coming from great depth through clay and granite," she says. "It was fabulous."</p><p>Today, Richardson gets her water from a city system that uses chloramine.</p>
Toxic Treadmill<p>Most community water systems in the U.S. use chlorine for disinfection in their treatment plant. Because disinfectants are needed to prevent bacteria growth as the water travels to the homes at the ends of the distribution lines, sometimes a second round of disinfection is also added in the pipes.</p><p>Here, systems usually opt for either chlorine or chloramine. "Chloramination is more long-lasting and does not form as many disinfection by-products through the system," says Steve Via, director of federal relations at the American Water Works Association. "Some studies show that chloramination may be more protective against organisms that inhabit biofilms such as Legionella."</p>
Alternative Approaches<p>When he moved to the U.S. from Germany, Prasse says he immediately noticed the bad taste of the water. "You can taste the chlorine here. That's not the case in Germany," he says.</p><p>In his home country, water systems use chlorine — if at all — at lower concentrations and at the very end of treatment. In the Netherlands, <a href="https://dwes.copernicus.org/articles/2/1/2009/dwes-2-1-2009.pdf" target="_blank">chlorine isn't used at all</a> as the risks are considered to outweigh the benefits, says Prasse. He notes the challenge in making a convincing connection between exposure to low concentrations of disinfection by-products and health effects, such as cancer, that can occur decades later. In contrast, exposure to a pathogen can make someone sick very quickly.</p><p>But many countries in Europe have not waited for proof and have taken a precautionary approach to reduce potential risk. The emphasis there is on alternative approaches for primary disinfection such as ozone or <a href="https://www.pbs.org/wgbh/nova/article/eco-friendly-way-disinfect-water-using-light/" target="_blank" rel="noopener noreferrer">ultraviolet light</a>. Reverse osmosis is among the "high-end" options, used to remove organic and inorganics from the water. While expensive, says Prasse, the method of forcing water through a semipermeable membrane is growing in popularity for systems that want to reuse wastewater for drinking water purposes.</p><p>Remucal notes that some treatment technologies may be good at removing a particular type of contaminant while being ineffective at removing another. "We need to think about the whole soup when we think about treatment," she says. What's more, Remucal explains, the mixture of contaminants may impact the body differently than any one chemical on its own. </p><p>Richardson's preferred treatment method is filtering the water with granulated activated carbon, followed by a low dose of chlorine.</p><p>Granulated activated carbon is essentially the same stuff that's in a household filter. (EWG recommends that consumers use a <a href="https://www.ewg.org/tapwater/reviewed-disinfection-byproducts.php#:~:text=EWG%20recommends%20using%20a%20home,as%20trihalomethanes%20and%20haloacetic%20acids." target="_blank" rel="noopener noreferrer">countertop carbon filter</a> to reduce levels of disinfection by-products.) While such a filter "would remove disinfection by-products after they're formed, in the plant they remove precursors before they form by-products," explains Richardson. She coauthored a <a href="https://pubs.acs.org/doi/10.1021/acs.est.9b00023" target="_blank" rel="noopener noreferrer">2019 paper</a> that concluded the treatment method is effective in reducing a wide range of regulated and unregulated disinfection by-products.</p><br>
Greater Cincinnati Water Works installed a granulated activated carbon system in 1992, and is still one of relatively few full-scale plants that uses the technology. Courtesy of Greater Cincinnati Water Works.<p>Despite the technology and its benefits being known for decades, relatively few full-scale plants use granulated active carbon. They often cite its high cost, Richardson says. "They say that, but the city of Cincinnati [Ohio] has not gone bankrupt using it," she says. "So, I'm not buying that argument anymore."</p><p>Greater Cincinnati Water Works installed a granulated activated carbon system in 1992. On a video call in December, Jeff Swertfeger, the superintendent of Greater Cincinnati Water Works, poured grains of what looks like black sand out of a glass tube and into his hand. It was actually crushed coal that has been baked in a furnace. Under a microscope, each grain looks like a sponge, said Swertfeger. When water passes over the carbon grains, he explained, open tunnels and pores provide extensive surface area to absorb contaminants.</p><p>While the granulated activated carbon initially was installed to address chemical spills and other industrial contamination concerns in the Ohio River, Cincinnati's main drinking water source, Swertfeger notes that the substance has turned out to "remove a lot of other stuff, too," including <a href="https://ensia.com/features/drinking-water-contamination-pfas-health/" target="_blank" rel="noopener noreferrer">PFAS</a> and disinfection by-product precursors.</p><p>"We use about one-third the amount of chlorine as we did before. It smells and tastes a lot better," he says. "The use of granulated activated carbon has resulted in lower disinfection by-products across the board."</p><p>Richardson is optimistic about being able to reduce risks from disinfection by-products in the future. "If we're smart, we can still kill those pathogens and lower our chemical disinfection by-product exposure at the same time," she says.</p><p><em>Reposted with permission from </em><em><a href="https://ensia.com/features/drinking-water-disinfection-byproducts-pathogens/" target="_blank">Ensia</a>. </em><a href="https://www.ecowatch.com/r/entryeditor/2649953730#/" target="_self"></a></p>
