On the IEA’s latest report, wildfires in North Carolina, and EV adoption
Current conditions: A wildfire in New Jersey’s Wharton State Forest has burned 2,300 acres • An ancient Roman bridge collapsed in central Spain after extreme rainfall from four consecutive storms • Los Angeles could see record-breaking March heat today with temperatures nearing 90 degrees Fahrenheit.
The ballooning price tag of President Trump’s tax cut wishlist and preliminary budget negotiations on the Hill are pointing toward a budgetary showdown in which many of the Inflation Reduction Act’s benefits could become fiscal casualties. D.C. veterans, including former GOP Hill staff, tell Heatmap that even the most bipartisan parts of the IRA could be sacrificed in the budget reconciliation process in order to make room for Trump’s biggest legislative priorities, including extending the 2017 Tax Cuts and Jobs Act, eliminating taxes on tips, overtime pay, and Social Security, and removing the cap on the state and local tax liability deductions.
The Congressional Budget Office, as well as third-party groups like the Tax Foundation and the Penn Wharton Budget Model, have estimated that an extension of the 2017 tax cuts would cost between $3.7 and $4.5 trillion through 2034. If all of Trump’s additional proposed tax cuts were enacted, the cost would jump to $6.8 trillion, according to Penn Wharton. Congress is still at the beginning of the reconciliation process. The next step is for the House and Senate to negotiate a topline number and issue instructions to the committees that will write the final bill on the levels of spending they’re allowed to include.
As Heatmap’s Emily Pontecorvo and Jael Holzman explain, the dollar amount assigned to each committee is a ceiling, and it’s calculated on a net basis. So if the Ways and Means committee, which oversees tax legislation, is assigned a $4.5 trillion deficit ceiling, as it was in the version of the reconciliation instructions that recently passed the House, it’s going to have to find several trillion dollars worth of spending programs to cut. Fully repealing the Inflation Reduction Act’s green energy tax credits — which, according to new modeling from the nonpartisan Tax Foundation, would raise about $850 billion — will start to look harder to avoid.
Major wildfires erupted in the Carolinas over the weekend, burning more than 4,000 acres and threatening some areas that were hit hard by Hurricane Helene six months ago. Debris from hurricanes makes already battered areas more vulnerable to fires, Colleen Hagerty wrote for Heatmap in the aftermath of Helene. And as Heatmap’s Jeva Lange wrote more recently, researchers are pointing to the South as a new area of wildfire concern.
South Carolina’s governor declared a state of emergency Saturday as the Table Rock fire spread to cover 300 acres in the Blue Ridge Mountains, prompting evacuations. In North Carolina, several large fires are raging out of control in Polk County, southeast of Ashville, where last year’s Hurricane Helene brought devastating floods and debris. Much of Polk County is enduring drought conditions. High winds, dry vegetation, and low humidity are fueling the fires, but response efforts are also hampered by steep terrain and hurricane debris that has yet to be cleared. Mandatory evacuations were in effect for some parts of Polk County.

Global energy demand rose by 2.2% last year, faster than the average pace seen over the past decade or so, according to the International Energy Agency’s Global Energy Review 2025 report. The rise was led mostly by the power sector as record warmth meant greater need for air conditioning, especially in emerging and developing countries. “Nearly all of the rise in electricity demand was met by low-emissions sources,” the report said, with renewables and nuclear providing 80% of the growth in global electricity generation. Energy-related carbon dioxide emissions rose last year (by 0.8%) but at a slower rate than in 2023. “The global increase of 300 million tonnes of CO2 was influenced by record high temperatures,” the report said. “If weather in 2024 had remained consistent with 2023, itself the second-hottest year on record, about half of the increase in global emissions would have been avoided.”
In case you missed it: We now know which grants the Environmental Protection Agency has canceled. A document the EPA shared with the Sierra Club in response to a Freedom of Information Act request shows 49 individual grants that were either “canceled” or prevented from being awarded from January 20 through March 7. The grants’ total cumulative value is more than $230 million, although some $30 million appears to have already been paid out to recipients. Nearly half of the canceled grants are related to environmental justice initiatives. Here’s the full list of grants, by program.
A new study finds that political views remain a key factor in determining whether someone chooses to buy an electric vehicle. The report, from the National Bureau of Economic Research, examined new EV registration data at a county level between 2012 and 2023 and found that during those years, the scale of the EV market expanded, yet nearly half of all sales were in the 10% most Democratic counties. Researchers controlled for other factors, such as income and gas prices, and still, the strong correlation between political ideology and EV adoption remains. And it hasn’t decreased over time. “We find little evidence that the U.S. EV market has broadened across the political spectrum from 2012 to 2023,” the researchers say. There were some exceptions, though: EV trucks and vans are “significantly less concentrated” in left-leaning counties compared to electric cars and SUVs.
California now has nearly 50% more EV chargers than it does gas pumps. According to the California Energy Commission, there are roughly 178,000 EV chargers in the state, compared with approximately 120,000 gas nozzles.

It’s already conquered solar, batteries, and EVs. With a $2 billion new turbine factory in Scotland, it may have set its next target.
Batteries, solar panels, electric vehicles. The story of renewable energy deployment globally is increasingly one of China’s fiercely competitive domestic industries and deep supply chains exporting their immense capacity globally. Now, it may be wind’s turn.
The Chinese turbine manufacturer Ming Yang announced last week that it plans to invest $2 billion in a factory in Scotland. The facility is scheduled to start production in late 2028, churning out offshore wind equipment for use in the United Kingdom, which has over 15 gigawatts of offshore wind capacity, as well as for export, likely in Europe.
The deal comes as China finds itself at a kind of domestic clean energy crossroads, in terms of both supply and demand. On the former, the country has launched a campaign aimed at softening the cutthroat domestic competition, overproduction, and price wars that have defined many of its green industries, especially electric vehicles.
At the same time, China is setting out to alter its electricity markets to put renewable energy on a more market-based footing, while also paying coal-fired power plants to stay on the grid, as University of California, San Diego researcher Michael Davidson explained on a recent episode of Shift Key. These changes in electricity markets will reduce payments to solar and wind producers, making foreign markets potentially more attractive.
“We anticipate Chinese original equipment manufacturers will intensify their push toward international expansion, with Mingyang’s planned investment a signal of this trend,” Morningstar analyst Tancrede Fulop wrote in a note to clients. “This poses a challenge for Western incumbents, as Chinese players can capitalize on their cost advantages in a market driven by price.”
Ironically, Fulop said, the market changes will make the Chinese market more like Europe’s, which has become more price conscious as the market has matured and reductions in cost have slowed or outright stopped. “The transition is expected to make renewable developers increasingly price-sensitive as they seek to preserve project returns, ultimately weighing on wind turbine manufacturers’ profitability,” he wrote.
There’s a “cliff” coming in Chinese renewable energy deployment, Kyle Chan, a postdoctoral researcher at Princeton University, told me. “Overall, the net effect is expected to be a pretty sharp drop, and we’re already starting to see some of the effects of that.”
And turbine manufacturers would not be the first Chinese renewable industry to show up in Europe.
“There’s already an existing model” for Chinese manufacturers to set up shop in Western countries, Chan said. Chinese companies are already planning to manufacture solar modules in France, while Chinese EV maker BYD’s is planning factories in Hungary, Turkey, and potentially Spain.
China as a whole is responsible for over half of all new offshore wind capacity added in 2024, according to Global Energy Monitor, and has been growing at a 41% annual rate for the past five years. The energy intelligence firm Rystad estimates that China will make up 45% of all offshore wind capacity by 2030. Ming Yang itself claims to be behind almost a third of new offshore wind capacity built last year.
Meanwhile, offshore wind projects in the West — especially the United States — have faced the omnicrisis of high interest rates, backed-up supply chains, and Donald Trump. News of Ming Yang’s Scotland factory sent yet another shock through the ailing Western offshore wind market, with shares in the Danish company Vestas down 4% when the market opened Monday.
But with Chinese products and Chinese investment comes controversy and nerves among European political leaders. “There’re questions about tech transfer and job creation,” Chan said. “They also face some security issues and potential political backlash.”
In August, the German asset manager Luxcara announced that it would use Siemens Gamesa turbines for a planned offshore wind project instead of Ming Yang ones after backlash from German defense officials. “We see this as further evidence that a Chinese entry into the European wind market remains challenging,” analysts at Jefferies wrote to clients in August.
They were right to be skeptical — Chinese turbines’ entry into the European market has been long predicted and yet remains unrealized. “China’s increasingly cheap wind turbines could open new markets,” S&P Global Insights wrote in 2022, citing the same cost advantages as Morningstar did in reference to the Ming Yang factory announcement.
“China was already trying to angle into the European market,” Chan told me, seeing it as comparable to the U.S. in size and potentially more open to Chinese investment. “If they were kind of thinking about it before, now it’s gotten a greater sense of commercial urgency because I think the expectation is that their profit margins are really going to get squeezed.”
While China leads the world in building out renewable energy capacity domestically and exporting technology abroad, it has “decided not to decide” on pursuing a rapid, near-term decarbonization, Johns Hopkins University China scholar Jeremy Wallace recently argued in Heatmap.
While that means that the Paris Agreement goals are even farther out of reach, it may be fine for Chinese industries, including wind, as they look to sell abroad.
“Chinese firms have lots of reasons to want to build things abroad: Diversification away from the Chinese market, the zero or negative profits from selling domestically, and geopolitical balancing,” Wallace told me.
“If Brits want to have their citizens making the turbines that will power the country,” Wallace said, “this seems like a reasonable opportunity.”
Current conditions: A major Pacific storm is drenching California and bringing several inches of snow to Montana, Idaho, and Wyoming • A tropical storm in the Atlantic dumped nearly a foot of water on South Carolina over three days • Algeria is roasting in temperatures of more than 105 degrees Fahrenheit.
The Department of Energy notified workers in multiple offices Friday that they were likely to be fired or reassigned to another part of the agency, E&E News reported Tuesday. Staffers at the Office of Clean Energy Demonstrations and the Office of State and Community Energy Programs received notices stating that the offices would “be undergoing a major reorganization and your position may be reassigned to another organization, transferred to another function or abolished.” Still, the notice said “no determination has been made concerning your specific position” just yet.
At least five offices received “general reduction in force notices,” as opposed to official notification of a reduction in force, according to a Latitude Media report. These included the Office of Clean Energy Demonstrations, the Office of Energy Efficiency and Renewable Energy, the Office of State and Community Energy Plans, and the Office of Fossil Energy. Nearly 200 Energy Department employees received direct layoff notices.
Catastrophic floods brought on by the remnants of a typhoon devastated the Alaska Native village of Kipnuk on Sunday. Five months ago, the Trump administration canceled a $20 million grant intended to protect the community against exactly this kind of extreme flooding, The New York Times reported Tuesday. The grant from the Environmental Protection Agency was meant to stabilize the riverbank on which Kipnuk is built. But in May, the agency yanked back the Biden-era grant, which EPA Administrator Lee Zeldin said was “no longer consistent” with the government’s priorities. In a post on X, Zeldin said the award was part of "wasteful DEI and Environmental Justice grants,” suggesting the funding was part of an ideological push for diversity, equity, and inclusion rather than a practical infrastructure boost to an Indigenous community facing serious challenges.
Zealan Hoover, a Biden-era senior adviser at the EPA, accused Zeldin of using “inflammatory rhetoric” that misrepresented the efforts in places like Kipnuk. “For decades, E.P.A. has been a partner to local communities,” Hoover said. “For the first time under this administration, E.P.A. has taken an aggressively adversarial posture toward the very people and communities that it is intended to protect.”

Late last Thursday, Heatmap’s Jael Holzman observed that the status of the 6.2-gigawatt Esmeralda 7, the nation’s largest solar project, had changed on the Bureau of Land Management’s website to “canceled.” The news sent shockwaves nationwide and drew blowback even from Republicans, including Utah Governor Spencer Cox, as I reported in this newsletter. Now, however, the bureau’s parent agency is denying that it made the call to cancel the project. “During routine discussions prior to the lapse in appropriations, the proponents and BLM agreed to change their approach for the Esmeralda 7 Solar Project in Nevada,” a spokesperson for the Department of the Interior told Utility Dive. “Instead of pursuing a programmatic level environmental analysis, the applicants will now have the option to submit individual project proposals to the BLM to more effectively analyze potential impacts.”
That means the project could still move forward with a piecemeal approach to permitting rather than one overarching approval, which aligns with what one of the developers involved told Jael last week. A representative for NextEra said that it is “in the early stage of development” with its portion of the Esmeralda 7 mega-project, and that the company is “committed to pursuing our project’s comprehensive environmental analysis by working closely with the Bureau of Land Management.” Still, the move represents a devastating setback for the solar installation, which may never fully materialize.
Ethane exports are rising as export capacity soars.EIA
U.S. exports of ethane, a key petrochemical feedstock extracted from raw natural gas during processing, are on track for “significant growth” through 2026, according to new analysis from the Energy Information Administration. Overseas sales are projected to grow 14% this year compared to the previous year, and another 16% next year. Ethane is mostly used as a feedstock for ethylene, a key ingredient in plastics, resins, and synthetic rubber. China has been the fastest growing source of demand for American ethane in recent years, rising to the largest single destination with 47% of exports last year.
Spain’s electricity-grid operator shrugged off concerns of another major blackout after detecting two sharp voltage variations in recent weeks. Red Electrica, which operates Spain’s grid, said that what The Wall Street Journal described as “recent voltage swings” didn’t threaten to knock out the grid because they stayed within acceptable limits. But the operator warned that variations could jeopardize the electricity supply if the grid didn’t overhaul its approach to managing a system that increasingly relies on intermittent, inverter-based generating sources such as solar panels. Red, which is 20% owned by the Spanish government, acknowledged that the high penetration of renewables was responsible for the recent fluctuations. Among the changes needed to improve the grid: real-time monitoring, which Heatmap’s Matthew Zeitlin noted in April “is necessary because traditionally, grid inertia is just thought of as an inherent quality of the system, not something that has to be actively ensured and bolstered.”
It’s not just Spain facing blackouts. New York City will have a power deficiency equivalent to the energy needed to power between 410,000 and 650,000 homes next summer — and that number could double by 2050, the state’s grid operator warned this week in its latest five-year report. “The grid is at a significant inflection point,” Zach Smith, senior vice president of system and resource planning for NYISO, said in a statement to Gothamist. “Depending on future demand growth and generator retirements, the system may need several thousand megawatts of new dispatchable generation within the next 10 years.”
Sodium-ion batteries are all the rage, as Heatmap’s Katie Brigham reported yesterday about the commercial breakthrough by the startup Alsym. But a major challenge facing sodium-ion batteries compared to lithium-ion rivals is the stability of the cathode material in air and water, which can degrade the battery’s performance and lifespan. A new study by researchers at Tokyo University of Science found that one ingredient can solve the problem: Calcium. By discovering the protective effects of calcium doping in the batteries, “this study could pave the way for the widespread adoption” of sodium-ion batteries.
Rob talks with the author and activist about his new book, We Survived the Night.
Julian Brave NoiseCat is a writer, Oscar-nominated filmmaker, champion powwow dancer, and student of Salish art and history. His first book, We Survived the Night, was released this week — it uses memoir, reporting, and literary anthology to tell the story of Native families across North America, including his own.
NoiseCat was previously an environmental and climate activist at groups including 350.org and Data for Progress. On this week’s episode of Shift Key, Rob talks with Julian about Native American nations and politics, the complexity and reality of Native life in 2025, and the “trickster” as a recurring political archetype.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University. Jesse is off this week.

Here is an excerpt from our conversation:
Robinson Meyer: What were lessons that you took away from the writing of the book, or from the reporting of the book, that changed how you thought about climate or the environment in some way that maybe wasn’t the case when you were working on these issues full time?
Julian Brave NoiseCat: I would say that while I was working on climate issues, I was actually, myself, really changing a lot in terms of my thoughts on how politics worked and did not work. I think I came into my period of my life as a climate activist really believing in the power of direct action, and protest, and, you know, if you get enough people in the streets and you get enough politicians on your side, you eventually can change the laws. And I think that there is some truth to that view.
But I think being in DC for four years, being really involved in this movement, conversation — however you want to put that — around the Green New Deal, around eventually a Biden administration and how that would be shaped around how they might go about actually taking on climate change for the first time in U.S. history in a significant way, really transformed my understanding of how change happens. I got a greater appreciation, for example, for the importance of persuading people to your view, particularly elites in decision-making positions. And I also started to understand a little bit more of the true gamesmanship of politics — that there is a bit of tricks and trickery, and all kinds of other things that are going on in our political system that are really fundamental to how it all works.
And I bring that last piece up because while I was writing the book, I was also thinking really purposefully about my own people’s narrative traditions, and how they get at transformations and how they happen in the world. And it just so happens that probably the most significant oral historical tradition of my own people is a story called a coyote story, which is about a trickster figure who makes change in the world through cunning and subterfuge and tricks, and also who gets tricked himself a fair amount.
And I think that in that worldview, I actually found a lot of resonance with my own observations on how political change happened when I was in Washington, D.C., and so that insight did really deeply shape the book.
