The president’s executive order is already too late to save at least one Arizona plant.

The Trump administration is trying to save coal again. But despite the president’s seemingly forceful actions, there’s little indication he’ll be any more successful at it this time than he was the last time around.
Backed by coal miners in hard hats and high visibility jackets, Trump on Tuesday announced a series of executive orders meant to boost “beautiful, clean coal.” The orders lift barriers to extracting coal on public lands, ask the Department of Energy to consider metallurgical coal a critical mineral, push out compliance with some air quality rules by two years, instruct the Department of Energy to use emergency authorities to keep coal plants open, and direct the attorney general to go after state climate laws that Trump claimed “discriminate” against greenhouse gas-emitting energy sources like coal.
What’s not clear is how much these orders will boost the coal industry, let alone save it. It’s not even clear whether the specific plant Trump said he was saving will burn coal again.
During the announcement, Trump said that his administration would keep open the Cholla Generating Station, an Arizona coal plant that began operating in 1962. The plant’s final two units were slated to be retired this year.
“We will ensure our nation’s critical coal plants remain online and operational,” Trump said. “To that end, I’m instructing Secretary Wright to save the Cholla coal plant in Arizona.”
But according to Arizona Public Service, the utility that co-owns the plant, the plant has already stopped generating power. A spokesperson told me the utility was “aware” of the president’s statement and is “evaluating what it means for the plant.” APS plans on preserving the site, possibly for nuclear power and has “procured reliable and cost-effective generation that will replace the energy previously generated by Cholla Power Plant,” the spokesperson said.
The Department of Energy didn’t return a request for comment.
Trump’s orders repeatedly cite Section 202 of the Federal Power Act, which allows the Secretary of Energy “during a continuance of a war in which the United States is engaged or when an emergency exists” to allow energy facilities to continue to operate on a temporary basis that otherwise would not.
In 2017, the first Trump administration used Section 202 to allow two coal plant units in Virginia to continue operating occasionally when necessary for grid reliability, despite their having been due to close to comply with air quality regulations. Two years later, the electricity market PJM told the Department of Energy that a new transmission line had rendered the emergency authorization unnecessary, and the plants closed in 2019.
The executive orders “don’t seem to realize that natural gas killed coal and if they aren’t banning fracking, none of this matters,” Grid Strategies president Rob Gramlich wrote on X. “Nothing here seems to change the economics, and it’s the economics that have held coal-fired power production down.” (Gramlich is also a Heatmap contributor.)
Of course, the United States has plenty of coal. But many of its uses — including electricity generation — can be easily substituted with other sources, such as natural gas. That’s why U.S. coal production has been falling since 2008.
“Coal is increasingly uncompetitive in deregulated electricity markets,” Seaver Wang, director of climate and energy at the Breakthrough Institute, told me. That’s because operating a coal-fired power plant comes with all sorts of extra costs that natural gas doesn’t, including the transportation and storage of coal — compare the barges and trains required to move rocks to the neat pipelines gas flows through. The energy research group Energy Innovation has found that nearly all coal plants are more expensive to run than the combinations of wind, solar, and storage that might replace them.
“I don’t see the demand drivers for this to remotely bring coal back. I have no idea who would ever invest as a result of this executive order or related policies,” Wang said.
While existing coal plants may stick around for another few years as a result of heightened demand or relaxed regulatory burdens, that’s a far cry from building new coal plants or opening new coal mines. A large coal plant hasn’t opened in the United States since 2013. In 2024, wind and solar generation surpassed coal generation on the grid, according to Ember.
Some 12.3 gigawatts of coal capacity are scheduled to be retired in 2025, according to the Energy Information Administration, making up two-thirds of planned retirements by capacity this year. But coal retirements have also been slowing down, according to EIA data. The 7.5 gigawatts retired last year was the least since 2011.
Jefferies analysts estimated that over 12 gigawatts of coal capacity is due for retirement in 2028. That could be pushed back thanks to the relaxation of the mercury and air toxics rules the president announced Tuesday.
“There is logic to delaying coal retirements to serve incremental high-density load customers like data centers,” the Jefferies analysts wrote. “Not all coal retirements are alike, and the economic-driven transitions will continue to draw support, but the calculus will change with more expensive renewables and natural gas alternatives from tariffs and potential changes to the Inflation Reduction Act.”
This is not the first time a Trump White House has tried to rescue this declining industry. During his first term, then Secretary of Energy Rick Perry proposed that coal and nuclear plants at risk of closing because of low demand have guaranteed payments, known as cost recovery, in order to stay open. The Federal Energy Regulatory Commission, with a Republican majority, said no to Perry by a vote of 5-0.
Despite the president’s promises throughout his campaign, the coal industry shrunk by a huge degree during his first term, part of a longer trend that brought down coal’s share in the electricity generating sector from about half in 2007 to 16% in 2023. During Trump’s time in office, coal mining jobs declined from 51,000 to 38,000 during the pandemic, and have recovered only to 40,000 today.
When it comes to mines, Wang said, investors would likely be leery of putting money into the sector, given the strong likelihood that a future Democratic administration would be far less friendly to coal. Coal investors “are going to be accounting for the fact that any policy swings are short lived,” Wang told me.
“We all know that lead times for mines are long. Everyone knows this administration only has four years in office. I don’t really expect that this will drive a lot of investment interest,” Wang said.
The critical mineral designation for coal, if it makes it through the Department of Energy’s process, may not change much initially, Wang explained. It could lead to some “beneficial outcomes in terms of agency prioritization,” he said. But much critical minerals policy is still being worked out, and there are few programs that specifically and programmatically target the critical minerals included on lists maintained by either the Department of Energy or the United States Geological Service.
“A lot of the politicking over critical minerals designation is about the expectation of future outcomes that would arise from broad bipartisan interest in critical minerals as a category,” Wang said.
And unlike with other critical minerals, the U.S. is essentially self-sufficient for coal’s industrial and energy uses. We’re not talking about graphite here, let alone praseodymium.
At least so far, the coal industry has not thrilled to having a more friendly figure in the White House, although the share prices of some coal companies are up in afternoon trading. Coal exports in January, the most recent month for which there is data, stood at 7.7 million short tons, compared to 8.4 million short tons a year prior. Central Appalachia coal prices stand at $78 per short ton, compared to $77.35 a year ago.
If nothing else, the announcements provided Trump with the type of photo-op he craves. He even got the opportunity to bash Hillary Clinton. “One thing I learned about the coal miners … they want to mine coal. She was gonna put them in a high-tech industry where you make little cell phones and things,” he told the audience in the White House. Of course, Secretary of Commerce Howard Lutnick on Sunday touted the “army of millions and millions of people screwing in little, little screws to make iPhones” that Trump’s tariffs will also help generate. But no matter what the president says or does, the coal industry may still be screwed.

The Trump administration’s rollback of coal plant emissions standards means that mercury is on the menu again.
It started with the cats. In the seaside town of Minamata, on the west coast of the most southerly of Japan’s main islands, Kyushu, the cats seemed to have gone mad — convulsing, twirling, drooling, and even jumping into the ocean in what looked like suicides. Locals started referring to “dancing cat fever.” Then the symptoms began to appear in their newborns and children.
Now, nearly 70 years later, Minimata is a cautionary tale of industrial greed and its consequences. Dancing cat fever and “Minamata disease” were both the outward effects of severe mercury poisoning, caused by a local chemical company dumping methylmercury waste into the local bay. Between the first recognized case in 1956 and 2001, more than 2,200 people were recognized as victims of the pollution, which entered the population through their seafood-heavy diets. Mercury is a bioaccumulator, meaning it builds up in the tissues of organisms as it moves up the food chain from contaminated water to shellfish to small fish to apex predators: Tuna. Cats. People.
In 2013, 140 countries, including the U.S., joined the Minamata Convention, pledging to learn from the mistakes of the past and to control the release of mercury into the environment. That included, explicitly, mercury in emissions from “coal-fired power plants.” Last month, however, the U.S. Environmental Protection Agency retreated from the convention by abandoning the 2024 Mercury and Air Toxics Standards, which had reduced allowable mercury pollution from coal-fired plants by as much as 90%. Nearly all of the 219 operating coal-fired plants in the U.S. already meet the previous, looser standard, set in 2012; Trump’s EPA has argued that returning to the older rules will save Americans $670 million in regulatory compliance costs by 2037.
The rollback — while not a surprise from an administration that has long fetishized coal — came as a source of immense frustration to scientists, biologists, and activists who’ve dedicated their careers to highlighting the dangers of environmental contaminants. Nearly all human exposure to methylmercury in the United States comes from eating seafood, according to the EPA, and it’s well-documented that adding more mercury to the atmosphere will increase levels in fish, even those caught far from fenceline communities.
“Mercury is an extremely toxic metal,” Nicholas Fisher, an expert in marine pollution at Stony Brook University, told me. “It’s probably among the most toxic of all the metals, and it’s been known for centuries.” In his opinion, it’s unthinkable that there is still any question of mercury regulations making Americans safer.
Gabriel Filippelli, the executive director of the Indiana University Environmental Resilience Institute, concurred. “Mercury is not a trivial pollutant,” he told me. “Elevated mercury levels cost millions of IQ points across the country.” The EPA rollback “actually costs people brain power.”
When coal burns in a power plant, it releases mercury into the air, where it can travel great distances and eventually end up in the water. “There is no such thing as a local mercury problem,” Filippelli said. He recalled a 2011 study that looked at Indianapolis Power & Light, a former coal plant that has since transitioned to natural gas, in which his team found “a huge plume of mercury in solids downwind” of the plant, as well as in nearby rivers that were “transporting it tens of kilometers away into places where people fish and eat what they catch.”
Earthworms and small aquatic organisms convert mercury in soils and runoff into methylmercury, a highly toxic form that presents the most danger to people, children, and the fetuses of pregnant women as it moves up the food chain. Though about 70% of mercury deposited in the United States comes from outside the country — China, for example, is the second-greatest source of mercury in the Great Lakes Basin after the U.S., per the National Oceanic and Atmospheric Administration — that still leaves a significant chunk of pollution under the EPA’s control.
There is, in theory, another line of defense beyond the EPA. For recreational fishers, of whom there are nearly 60 million in the country each year, state-level advisories on which waterways are safe to fish in based on tests of methylmercury concentrations in the fish help guide decisions about what is safe to eat. Oregon, for example, advises that people not eat more than one “resident fish,” such as bass, walleye, and carp, caught from the Columbia River per week — and not eat any other seafood during that time, either. Forty-nine states have some such advisories in place; the only state that doesn’t, coal-friendly Wyoming, has refused to test its fish. One also imagines that safe waterways will start to become more limited if the coal-powered plants the Trump administration is propping up forgo the expensive equipment necessary to scrub their emissions of heavy metals.
“It’s not something where you’re going to see a dramatic change overnight,” Tasha Stoiber, a senior scientist with the Environmental Working Group, a research and advocacy nonprofit that focuses on toxic chemicals, told me. “But depending on the water body that you’re fishing in, you want to seek out state advisories.”
For people who prefer to buy their fish at the store, the Food and Drug Administration sets limits on the amount of mercury allowed in commercial seafood. But Kevin McCay, the chief operations officer at the seafood company Safe Catch, told me the FDA’s limit of 1 part per million for methylmercury is outrageously high compared with limits in the European Union and Japan. “It has to be glowing red before the FDA is actually going to do anything,” he said. (Watchdog groups have likewise warned that the hemorrhaging of civil servants from the FDA will have downstream consequences for food safety.)
McCay also told me that he “certainly” expects mercury levels in the fish to rise due to the EPA’s decision. Unlike other canned tuna companies that test batches of fish, Safe Catch drills a small test hole in every fish it buys to ensure the mercury content is well below the FDA’s limits. (Fish that are lower on the food chain, like salmon, are the safest choices, while fish at the top of the food chain, like tuna, sharks, and swordfish, are the worst.)
The obsessive oversight gives the company a front-seat view of where and how methylmercury is working its way up the food chain, and McCay worries his company could face more limited sourcing options in the coming years if policies remain friendly to coal. (An independent investigation by Consumer Reports in 2023 found that even fish sourced by an ultra-cautious company like Safe Catch contain some level of mercury. “There’s probably no actual safe amount,” McCay told me, recommending that customers should eat a diverse range of seafood to limit exposure.)
Even people who don’t eat fish should be concerned, though. That’s because, as Filippelli told me, “a lot of [contaminated] fish meal is being incorporated into pet food.”
There are no regulatory standards for mercury in pet foods. But avoiding mercury is not as simple as bypassing the tuna-flavored kibble, Sarrah M. Dunham-Cheatham, who authored a 2019 study on mercury in pet food, told me. Even many brands that don’t list fish among their ingredients contain fish meal that is high in mercury, she said.
Different species also have different sensitivities to mercury, with chimpanzees and cats being among the most sensitive. “I don’t want to be alarmist or scare people,” Dunham-Cheatham said. But because of the issues with labeling pet food, there isn’t much to be done to limit mercury intake in your pets — that is, short of dealing with the emissions on local and planetary scales. “We’re expecting there to be more emissions to the atmosphere, more deposition to aquatic environments, and therefore more mercury accumulated into proteins that will go into making the pet foods,” she said.
To Fisher, the Stony Brook professor, the Trump administration’s decision to walk back mercury restrictions makes no sense at all. The Ancient Romans understood the dangers of mercury; the dancing cats of Minamata are now seven decades behind us. “Why should we make the underlying assumption that the mercury is innocent until proven guilty?” he said.
On Qatari aluminum, floating offshore wind, and Taiwanese nuclear
Current conditions: Upstate New York and New England are facing another 2 inches of snow • A heat wave in India is sending temperatures in Gujarat beyond 100 degrees Fahrenheit • Record-breaking rain is causing flash flooding in South Australia, New South Wales, and Victoria.
The war with Iran is shocking oil and natural gas prices as the Strait of Hormuz effectively closes and Americans start paying more at the pump. “So despite the stock market overall being down, clean energy companies’ shares are soaring, right?” Heatmap’s Matthew Zeitlin wrote yesterday. “Wrong. First Solar: down over 1% on the day. Enphase: down over 3%. Sunrun: down almost 8%; Tesla: down around 2.5%.” What’s behind the slump? Matthew identified three reasons. First, there was a general selloff in the market. Second, supply chain disruptions could lead to inflation, which might lead to higher interest rates, or at the very least slow the planned cycle of cuts. Third, governments may end up trying “to mitigate spiking fuel prices by subsidizing fossil fuels and locking in supply contracts to reinforce their countries’ energy supplies,” meaning renewables “may thereby lose out on investment that might more logically flow their way.”
The U.S. liquified natural gas industry is certainly looking at boom times. U.S. developers signed sale and purchase agreements for 40 million tons per year in 2025 from planned export facilities, according to new Department of Energy data the Energy Information Administration posted. That’s the highest volume since 2022, when Russia’s invasion of Ukraine sent demand for American LNG soaring. That conflict, too, is still having its effects on global fossil fuel supplies. A Russian-flagged LNG tanker is on fire in the Mediterranean Sea as the result of a drone strike by Ukraine, The Independent reported Wednesday.
It’s not just fossil fuels. Qatari smelter Qatalum started shutting down on Tuesday as 50% shareholder Norsk Hydro issued a force majeure notice to customers. “The decision to shut down was made after the company’s gas supplier informed it of a forthcoming suspension of its gas supply,” the company said in a statement to Mining.com. QatarEnergy — which owns 51% of Qatalum’s other shareholder, Qatar Aluminum Manufacturing Co. — had previously suspended production after halting output of natural gas due to Iranian drone attacks.

Panel manufacturer Silfab Solar paused production at its South Carolina factory in Fort Mill after a chemical spill triggered a regulatory investigation. The plant accidentally spilled approximately 300 gallons of a water solution containing less than 0.3% potassium hydroxide. Experts told WCNC, the Charlotte-area NBC News affiliate, that the volume of the caustic chemical that spilled will be harmless. But the state Department of Environmental Services “asked Silfab to cease receipt of additional chemicals at their facility until an investigation is complete.” Such accidents risk political backlash at a time of heightened public health anxiety over clean energy technologies. As Heatmap’s Jael Holzman wrote last summer, the Moss Landing battery factory fire sparked a nationwide backlash.
Two-thirds of offshore wind potential is located at sites where the water is too deep for traditional turbine platforms. But the first wind farm with floating platforms only came into operation nine years ago. The largest so far, located in Norway’s stretch of the North Sea, is just under 100 megawatts. So, if completed, Spanish developer Ocean Winds’ in the United Kingdom would be by far the largest plant. The company took a step forward on the 1.5-gigawatt project when the company signed the lease agreement this week, according to OffshoreWIND.biz.
In Denmark, meanwhile, right-wing politicians are campaigning against the country’s offshore wind giant, Orsted. The country’s conservative Liberal party campaigned on divesting from the company, which claims the Danish government as its largest shareholder, back in 2022. Now, Bloomberg reported, the party is once against renewing its calls to exit Orsted after this year’s election.

Facing surging electricity demand and mounting threats of blackouts from Chinese attacks on energy imports, Taiwan is taking yet another step toward reversing its nuclear phaseout. Nearly a year after the island nation’s last reactor shut down, Taiwanese Premier Cho Jung-tai, a member of the ruling Democratic Progressive Party that has long opposed atomic energy, announced new proposals to allow the state-owned Taiwan Power Company to submit plans to restart at least two of the country’s three shuttered nuclear stations. (A fourth plant, called Lungmen, was nearly completed in the late 2010s before the DPP government canceled its construction.) The government report also said Taiwan may consider building new nuclear technologies, such as small modular reactors or fusion plants.
In June 2023, thousands of lightning strikes in heat wave-baked Quebec sparked more than 120 wildfires that ultimately scorched nearly 7,000 acres of parched forests. Lightning, in fact, starts almost 60% of wildfires. Now a Vancouver-based weather modification startup called Skyward Wildfire says it can prevent catastrophic blazes by stopping lightning strikes through cloud seeding. MIT Technology Review found some good reasons to doubt the company’s claims. But experts said preventing wildfires is cheaper than putting them out, so it may have some merit.
The attacks on Iran have not redounded to renewables’ benefit. Here are three reasons why.
The fragility of the global fossil fuel complex has been put on full display. The Strait of Hormuz has been effectively closed, causing a shock to oil and natural gas prices, putting fuel supplies from Incheon to Karachi at risk. American drivers are already paying more at the pump, despite the United States’s much-vaunted energy independence. Never has the case for a transition to renewable energy been more urgent, clear, and necessary.
So despite the stock market overall being down, clean energy companies’ shares are soaring, right?
Wrong.
First Solar: down over 1% on the day. Enphase: down over 3%. Sunrun: down almost 8%; Tesla: down around 2.5%.
Why the slump? There are a few big reasons:
Several analysts described the market action today as “risk-off,” where traders sell almost anything to raise cash. Even safe haven assets like U.S. Treasuries sold off earlier today while the U.S. dollar strengthened.
“A lot of things that worked well recently, they’re taking a big beating,” Gautam Jain, a senior research scholar at the Columbia University Center on Global Energy Policy, told me. “It’s mostly risk aversion.”
Several trackers of clean energy stocks, including the S&P Global Clean Energy Transition Index (down 3% today) or the iShares Global Clean Energy ETF (down over 3%) have actually outperformed the broader market so far this year, making them potentially attractive to sell off for cash.
And some clean energy stocks are just volatile and tend to magnify broader market movements. The iShares Global Clean Energy ETF has a beta — a measure of how a stock’s movements compare with the overall market — higher than 1, which means it has tended to move more than the market up or down.
Then there’s the actual news. After President Trump announced Tuesday afternoon that the United States Development Finance Corporation would be insuring maritime trade “for a very reasonable price,” and that “if necessary” the U.S. would escort ships through the Strait of Hormuz, the overall market picked up slightly and oil prices dropped.
It’s often said that what makes renewables so special is that they don’t rely on fuel. The sun or the wind can’t be trapped in a Middle Eastern strait because insurers refuse to cover the boats it arrives on.
But what renewables do need is cash. The overwhelming share of the lifetime expense of a renewable project is upfront capital expenditure, not ongoing operational expenditures like fuel. This makes renewables very sensitive to interest rates because they rely on borrowed money to get built. If snarled supply chains translate to higher inflation, that could send interest rates higher, or at the very least delay expected interest rate cuts from central banks.
Sustained inflation due to high energy prices “likely pushes interest rate cuts out,” Jain told me, which means higher costs for renewables projects.
While in the long run it may make sense to respond to an oil or natural gas supply shock by diversifying your energy supply into renewables, political leaders often opt to try to maintain stability, even if it’s very expensive.
“The moment you start thinking about energy security, renewables jump up as a priority,” Jain said. “Most countries realize how important it is to be independent of the global supply chain. In the long term it works in favor of renewables. The problem is the short term.”
In the short term, governments often try to mitigate spiking fuel prices by subsidizing fossil fuels and locking in supply contracts to reinforce their countries’ energy supplies. Renewables may thereby lose out on investment that might more logically flow their way.
The other issue is that the same fractured supply chain that drives up oil and gas prices also affects renewables, which are still often dependent on imports for components. “Freight costs go up,” Jain said. “That impacts clean energy industry more.”
As for the Strait of Hormuz, Trump said the Navy would start escorting ships “as soon as possible.”
