On the real copper gap, Illinois’ atomic mojo, and offshore headwinds

Last week, the Environmental Protection Agency repealed the “endangerment finding” that undergirds all federal greenhouse gas regulations, effectively eliminating the justification for curbs on carbon dioxide from tailpipes or smokestacks. That was great news for the nation’s shrinking fleet of coal-fired power plants. Now there’s even more help on the way from the Trump administration. The agency plans to curb rules on how much hazard pollutants, including mercury, coal plants are allowed to emit, The New York Times reported Wednesday, citing leaked internal documents. Senior EPA officials are reportedly expected to announce the regulatory change during a trip to Louisville, Kentucky on Friday. While coal plant owners will no doubt welcome less restrictive regulations, the effort may not do much to keep some of the nation’s dirtiest stations running. Despite the Trump administration’s orders to keep coal generators open past retirement, as Heatmap’s Matthew Zeitlin wrote in November, the plants keep breaking down.
At the same time, the blowback to the so-called climate killshot the EPA took by rescinding the endangerment finding has just begun. Environmental groups just filed a lawsuit challenging the agency’s interpretation of the Clean Air Act to cover only the effects of regional pollution, not global emissions, according to Landmark, a newsletter tracking climate litigation.
Copper prices — as readers of this newsletter are surely well aware — are booming as demand for the metal needed for virtually every electrical application skyrockets. Just last month, Amazon inked a deal with Rio Tinto to buy America’s first new copper output for its data center buildout. But new research from a leading mineral supply chain analyst suggests the U.S. can meet 145% of its annual demand using raw copper from overseas and domestic mines and from scrap. By contrast, China — the world’s largest consumer — can source just 40% of its copper that way. What the U.S. lacks, according to Benchmark Mineral Intelligence, is the downstream processing capacity to turn raw copper into the copper cathode manufacturers need. “The U.S. is producing more copper than it uses, and is far more self-reliant than China in terms of raw materials,” Benchmark analyst Albert Mackenzie told the Financial Times. The research calls into question the Trump administration’s mineral policy, which includes stockpiling copper from jointly-owned ventures in the Democratic Republic of the Congo and domestically. “Stockpiling metal ores doesn’t help if you don’t have midstream processing,” Stephen Empedocles, chief executive of US lobbying firm Clark Street Associates, told the newspaper.

Illinois generates more of its power from nuclear energy than any other state. Yet for years the state has banned construction of new reactors. Governor JB Pritzker, a Democrat, partially lifted the prohibition in 2023, allowing for development of as-yet-nonexistent small modular reactors. With excitement about deploying large reactors with time-tested designs now building, Pritzker last month signed legislation fully repealing the ban. In his state of the state address on Wednesday, the governor listed the expansion of atomic energy among his administration’s top priorities. “Illinois is already No. 1 in clean nuclear energy production,” he said. “That is a leadership mantle that we must hold onto.” Shortly afterward, he issued an executive order directing state agencies to help speed up siting and construction of new reactors. Asked what he thought of the governor’s move, Emmet Penney, a native Chicagoan and nuclear expert at the right-leaning Foundation for American Innovation, told me the state’s nuclear lead is “an advantage that Pritzker wisely wants to maintain.” He pointed out that the policy change seems to be copying New York Governor Kathy Hochul’s playbook. “The governor’s nuclear leadership in the Land of Lincoln — first repealing the moratorium and now this Hochul-inspired executive order — signal that the nuclear renaissance is a new bipartisan commitment.”
The U.S. is even taking an interest in building nuclear reactors in the nation that, until 1946, was the nascent American empire’s largest overseas territory. The Philippines built an American-made nuclear reactor in the 1980s, but abandoned the single-reactor project on the Bataan peninsula after the Chernobyl accident and the fall of the Ferdinand Marcos dictatorship that considered the plant a key state project. For years now, there’s been a growing push in Manila to meet the country’s soaring electricity needs by restarting work on the plant or building new reactors. But Washington has largely ignored those efforts, even as the Russians, Canadians, and Koreans eyed taking on the project. Now the Trump administration is lending its hand for deploying small modular reactors. The U.S. Trade and Development Agency just announced funding to help the utility MGEN conduct a technical review of U.S. SMR designs, NucNet reported Wednesday.

Despite the American government’s crusade against the sector, Europe is going all in on offshore wind. For a glimpse of what an industry not thrust into legal turmoil by the federal government looks like, consider that just on Wednesday the homepage of the trade publication OffshoreWIND.biz featured stories about major advancements on at least three projects totaling nearly 5 gigawatts:
That’s not to say everything is — forgive me — breezy for the industry. Germany currently gives renewables priority when connecting to the grid, but a new draft law would give grid operators more discretion when it comes to offshore wind, according to a leaked document seen by Windpower Monthly.
American clean energy manufacturing is in retreat as the Trump administration’s attacks on consumer incentives have forced companies to reorient their strategies. But there is at least one company setting up its factories in the U.S. The sodium-ion battery startup Syntropic Power announced plans to build 2 gigawatts of storage projects in 2026. While the North Carolina-based company “does not reveal where it manufactures its battery systems,” Solar Power World reported, it “does say” it’s establishing manufacturing capacity in the U.S. “We’re making this move now because the U.S. market needs storage that can be deployed with confidence, supported by certification, insurance acceptance, and a secure domestic supply chain,” said Phillip Martin, Syntropic’s chief executive.
For years now, U.S. manufacturers have touted sodium-ion batteries as the next big thing, given that the minerals needed to store energy are more abundant and don’t afford China the same supply-chain advantage that lithium-ion packs do. But as my colleague Katie Brigham covered last April, it’s been difficult building a business around dethroning lithium. New entrants are trying proprietary chemistries to avoid the mistakes other companies made, as Katie wrote in October when the startup Alsym launched a new stationary battery product.
Last spring, Heron Power, the next-generation transformer manufacturer led by a former Tesla executive, raised $38 million in a Series A round. Weeks later, Spain’s entire grid collapsed from voltage fluctuations spurred by a shortage of thermal power and not enough inverters to handle the country’s vast output of solar power — the exact kind of problem Heron Power’s equipment is meant to solve. That real-life evidence, coupled with the general boom in electrical equipment, has clearly helped the sales pitch. On Wednesday, the company closed a $140 million Series B round co-led by the venture giants Andreessen Horowitz and Breakthrough Energy Ventures. “We need new, more capable solutions to keep pace with accelerating energy demand and the rapid growth of gigascale compute,” Drew Baglino, Heron’s founder and chief executive, said in a statement. “Too much of today’s electrical infrastructure is passive, clunky equipment designed decades ago. At Heron we are manifesting an alternative future, where modern power electronics enable projects to come online faster, the grid to operate more reliably, and scale affordably.”
New data from the Clean Investment Monitor shows the first year-over-year quarterly decline since the project began.
Investment in the clean economy is flagging — and the electric vehicle supply chain is taking the biggest hit.
The Clean Investment Monitor, a project by the Rhodium Group and the Massachusetts Institute of Technology’s Center for Energy and Environmental Policy Research that tracks spending on the energy transition, found that total investment in clean technology in the last three months of 2025 was $60 billion. That compares to $68 billion in the fourth quarter of 2024 and $79 billion in the third quarter of last year. While total clean investment in 2025 was $277 billion — the highest the group has ever recorded — the fourth quarter of 2025 was the first time since the Clean Investment Monitor began tracking that the numbers fell compared to the same quarter the year before.
“Since 2019, quarterly investment has surpassed the level observed in the same period of the previous year — even when quarter-on-quarter declines occurred,” the report says. “That trend ended in Q4 2025, when investment declined 11% from the level observed in Q4 2024.”
It starts downstream, with consumer purchases of clean energy technology once favored by federal tax policy: electric vehicles, heat pumps, and home electricity generation. Consumer purchases fell 36% from the third quarter to the fourth quarter, after the $7,500 federal EV credit expired on September 30.
With a consumer market for EVs being undercut, car companies responded by canceling projects and redirecting investment.
“There were a lot of big, multi-billion dollar cancellations coming from Ford specifically,” Harold Tavarez, a research analyst at Rhodium, told me. There’s been a lot of pivots from having fully electric vehicles to doing more hybrids, more internal combustion, and even extended range EVs.”
Ford alone took an almost $20 billion hit on its EV investments in 2025. The company suspended production of its all-electric F-150 Lightning late last year, despite its status as the best-selling electric pickup in the country for 2025, and announced a pivot into hybrids and extended-range EVs (which have gasoline-powered boosters onboard), including a revamped Lightning. It has also announced plans to convert some manufacturing facilities designed to produce EVs back into internal combustion plants, but it hasn’t abandoned electricity entirely. Other decommissioned EV factories will instead produce battery electric storage systems, and the company has announced a pivot to smaller, cheaper EVs.
Ford is far from alone in its EV-related pain, however. Rival Big Three automaker GM also booked $6 billion in losses for 2025, while Stellantis, the European parent company of the Chrysler, Dodge, and Jeep brands, will take as much as $26 billion in charges. EV sales fell some 46% in the fourth quarter of last year compared to the third quarter, and 36% compared to the fourth quarter of 2024, according to Cox Automotive.
Looking at the investment data holistically, the true dramatic decline was in forward-looking announcements, again heavily concentrated in the EV supply chain. The $3 billion in clean manufacturing announced in the fourth quarter of last year was an almost 50% drop from the previous quarter, “marking this quarter as the lowest period of announcements since Q4 2020,” the report says. Announcements were down about 25% for the year as a whole compared to 2024. Of the $29 billion of canceled projects Clean Investment Monitor tracked from 2018 through the end of last year, almost three quarters — some $23 billion — happened in 2025.
“Collectively, we estimate around 27,000 operational jobs in the manufacturing segment were affected by cancellations,” the report says, “two-thirds (68%) of which were tied to projects canceled in 2025.”
“One of the most frustrating parts of watching Trump wage war on all things clean energy is the apparent lack of understanding — or care — of how it impacts his stated goals,” Alex Jacquez, a former Biden economic policy official who is chief of policy and advocacy at the Groundwork Collective, told me. “The IRA built a real, competitive manufacturing base in the U.S. in a new sector for the first time in decades. Administration priorities are being hampered by blind opposition to anything Biden, IRA, or clean energy.”
