It’s the Obama playbook, but different.

It was — against all odds — an energy debate.
Just look at the statistics. The word “fracking” was mentioned 10 times. “Oil” came up seven times. Even “climate change,” which Donald Trump was not very eager to talk about, was mentioned four times. And while that may not seem like a lot for such a vast and globe-spanning problem, climate change came up only three times in all of 2016’s debates combined.
Even more than when talking about trade or inflation, Vice President Kamala Harris and former President Donald Trump used energy to make their economic vision concrete and meaningful to Americans. For Harris, that meant recognizing the scale of the country’s fossil fuel resources today while gesturing toward a cleaner and lower-carbon future that will produce (in theory, at least) lots of high-wage manufacturing jobs for America’s middle class. For Trump, the energy industry — and, really, the fossil fuel industry — is central to his fleshy, authoritarian vision of American strength. Seemingly any attempt to replace hydrocarbons with something cleaner or less polluting arises from nothing less than an elite conspiracy to weaken the country and sell out its people.
For such a stark contrast — and for such an outlandish contrast, to be clear — it was a surprisingly substantive debate. Which isn’t to say we learned much, especially about Trump. The Republican nominee was the same man we’ve seen for the past nine years, the same politician who has defined the extreme GOP position on global warming. Over the past near-decade, Trump has called climate change a “hoax” and has seemed to revel in emissions-increasing policies. That isn’t changing. Asked directly what he would do about climate change on Tuesday night, he did not address the question at all. Instead, he talked about how car factories are getting built in Mexico, and he claimed in a difficult-to-follow rant that Joe Biden is getting paid off by China.
About Harris, we learned far more. Harris struck a careful, moderate tone during the debate between the need for climate action and the ongoing importance of fossil fuel extraction. She spoke about the Inflation Reduction Act, the Biden administration’s signature climate policy, but also discussed how it increased federal leasing for oil and gas. She spoke about climate change in terms of its higher everyday costs for Americans, and not — as Biden did — as an existential threat to the country.
“What we know is that [climate change] is very real,” she said. “You ask anyone who lives in a state who has experienced these extreme weather occurrences, who now is either being denied home insurance or [it] is being jacked up.”
She bragged about the Biden administration’s oil and gas record in the same breath as she discussed its enormous investments in clean energy. American oil and gas production is at an all-time high — it is higher, in fact, than Saudi Arabia’s — but I can’t remember hearing a Biden administration official bragging about that.
“I am proud that as vice president over the last four years, we have invested a trillion dollars in a clean energy economy while we have also increased domestic gas production to historic levels,” she said.
In a way, Harris has essentially returned to Obama’s 2012 “all of the above” energy policy. That approach remains unpopular with climate activists, who think it did too much for the oil and gas industry; personally, I think it’s an open question whether Obama actually believed in the “all of the above” approach or was subtly trying to help renewables all along. But more importantly, the underlying policy context is totally different now than it was 12 years ago: With the Inflation Reduction Act in place, the government can more easily bless all forms of energy development because it is, in fact, helping clean energy take root.
What’s most important, though — and what I hope climate advocates do not overlook — is that Harris’s tack here reflects the broad state of American public opinion. While most Americans want to reduce greenhouse gas emissions, they do not seem to want an energy revolution: More than two-thirds of Americans believe the country should use a mix of renewables and fossil fuels, according to the Pew Research Center, and less than a third believe the country should rely “entirely” on renewables. In the same poll, most Americans said they oppose federal rules that would aim to make electric vehicles half of all new cars sold by 2032.
This is not to say that Americans are big oil lovers. Most Americans think the country should prioritize various forms of zero-carbon energy development over fossil fuels. And while Republican support for renewables has dropped over the past few years — and has fallen further over the past few months, as my colleague Matthew Zeitlin wrote recently — a generation gap has emerged wherein younger Republicans are much more likely to champion solar and wind than older party members.
Even among seemingly environmental-aligned demographics, greater support exists for fossil fuels than one might expect. Most Democrats say they would not “favor” expanding fracking or offshore drilling — but about a quarter of Democrats would favor more fossil fuel drilling. So would roughly 45% of independents and, of course, a large majority of Republicans, according to Pew.
Of course, these facts of public opinion sit uneasily with what we know about climate change, which is that greenhouse gas emissions — and fossil fuel development with it — should plan to scale down soon. The International Energy Association has said that the most likely pathway for keeping global warming to 1.5 degrees Celsius requires the development of “no new long lead-time upstream oil or gas projects.” This observation provides less guidance for American policy makers than it might initially seem, because it is really focused on the opening of new, massive oil fields like Guyana’s. (The IEA also says, in almost the same breath, that “continued investment is required in some existing oil and gas projects,” which could possibly justify ongoing extraction from Texas’s well-established oil and gas fields.)
But even then, the non-negotiable fact would remain: The world must move away from fossil fuels. And the American people are not generally ready to do that today. The country wants something closer to an “all of the above” strategy than it wants a Green New Deal.
That strategy brings climate policy out of the ideological realm and into the pragmatic. Americans, polling suggests, like renewables in part because they will let the United States reduce its dependence on foreign oil, a popular idea in and of itself and talking point of both parties going back decades.
When Heatmap polled more than 5,000 Americans last month, more than half said that a “strong benefit” of a given clean energy project would be its ability to reduce the country’s dependence on foreign oil and natural gas. Among respondents, those putative energy independence benefits were the No. 2 most popular reason to support clean energy; the only more popular rationale for backing a project was that it would cut utility bills.
Harris directly echoed that appeal on Tuesday. “My position is that we have got to invest in diverse sources of energy so we reduce our reliance on foreign oil,” she said. “We have had the largest increase in domestic oil production in history because of an approach that recognizes that we cannot over rely on foreign oil.”
I can’t remember Biden making an appeal like this. When he talks about clean energy or the IRA, he tends to focus on its potential to grow the economy. Harris did some of that on Tuesday, bragging about the 800,000 new manufacturing jobs created during her vice presidency. But her focus on the national interest — and on the Biden administration’s appreciation of the ongoing fossil boom — was new.
Such an approach is unlikely to help her appeal to climate activists and advocates, who want the government to affirmatively begin to shutter fossil capacity. The Sunrise Movement, a climate activist group, criticized Harris on Tuesday for spending “more time promoting fracking than laying out a bold vision for a clean energy future.”
What I’d advise those advocates to keep in mind is that their views are legitimately not very popular, and Harris is trying to win a very close election in a race that her team believes has potentially existential stakes for American democracy. She also remembers the 2020 primary, when she tacked left on virtually every issue — she promised to ban fracking, for instance — and still lost. (If that’s because many of the groups wound up backing Bernie Sanders in that primary, that only reinforces the view that she can’t win over those voters in the first place.)
Harris isn’t defying the left on every issue — she has resisted neoliberal dogma and pandered to the public’s views on price gouging, for instance, putting her more in line with the Democratic Party’s Elizabeth Warren wing. But unlike Biden, she refuses to pay an electoral price for backing left-wing policies. Indeed, she seems to believe that she cannot pay such a price and still win. If Harris is now bragging about her administration’s support for fossil fuels, if she is casting the Inflation Reduction Act as a law that helped fracking, that means climate activists have much more work to do to persuade the public on what they believe. The Democratic Party’s candidate will not do that persuasion for them. And in any case, activists are not going to convince the public to believe something in the next 54 days that they’ve failed to do in the past five years.

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.
Beyond Fish Sticks
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.”
