Some of the Loan Programs Office’s signature programs are hollowed-out shells.

With a stroke of President Trump’s Sharpie, the One Big Beautiful Bill Act is now law, stripping the Department of Energy’s Loan Programs Office of much of its lending power. The law rescinds unobligated credit subsidies for a number of the office’s key programs, including portions of the $3.6 billion allocated to the Loan Guarantee Program, $5 billion for the Energy Infrastructure Reinvestment Program, $3 billion for the Advanced Technology Vehicle Manufacturing Program, and $75 million for the Tribal Energy Loan Guarantee Program.
Just three years ago, the Inflation Reduction Act supercharged LPO, originally established in 2005 to help stand up innovative new clean energy technologies that weren’t yet considered bankable for the private sector, expanding its lending authority to roughly $400 billion. While OBBBA leaves much of the office’s theoretical lending authority intact, eliminating credit subsidies means that it no longer really has the tools to make use of those dollars.
Credit subsidies represent the expected cost to the government of providing a loan or a loan guarantee — including the possibility of a default — and thus how much money Congress must set aside to cover these potential losses. So by axing these subsidies, Congress is effectively limiting the amount of lending that the LPO can undertake, given that many third-party lenders would be reluctant to finance riskier, more novel, or larger projects in the absence of federal credit support.
“The LPO is statutorily allowed to take loans on its books to finance these projects in these categories, but it has no credit subsidy by which to take the risk required to do so,” Advait Arun, senior associate of energy finance at the Center for Public Enterprise and a Heatmap contributor, told me.
The particular programs that have been eliminated support new and improved energy technologies, clean energy infrastructure, fuel efficient vehicles, and help native communities access energy project financing. The long-running Loan Guarantee Program and the advanced vehicles program in particular are behind some of the best known LPO efforts, supporting companies such as Tesla, Ford, and NextEra Energy, and projects such as Georgia’s Vogtle nuclear reactors, the Thacker Pass lithium mine, and Shepherd’s Flat, one of the world’s largest wind farms.
The Loan Guarantees Program is “the big Kahuna,” Arun told me. “This is the longest-standing program of the LPO. So to see this defunded is like, you’re decapitating the LPO’s crown jewel.”
The program only has about $11 million left over in credit subsidies, consisting of funding that it received prior to the IRA’s appropriations. That won’t be enough to make any meaningful loans, Arun said, and is more likely to be used to “keep a skeleton crew online” for any remaining administrative tasks.
Then there’s the Energy Infrastructure Reinvestment Program, which the IRA stood up with a whopping $250 billion in lending authority to transition and transform existing fossil fuel infrastructure for clean energy purposes. Now, OBBBA has axed the program’s remaining $5 billion in credit subsidies and replaced it with $1 billion in new subsidies for projects that “retool, repower, repurpose, or replace” existing energy infrastructure, with a focus on expanding capacity and output as opposed to decarbonizing the economy. It also refashioned the program as the predictably-named “Energy Dominance Financing” initiative.
The new-old program — which the law extended through 2028 — no longer requires LPO-funded infrastructure to reduce or sequester emissions, broadening the office’s lending authority to include support for fossil fuel and critical minerals projects. It also adds language encouraging the LPO to “support or enable the provision of known or forecastable electric supply,” which Arun fears is a “backend way of penalizing the addition of renewable energy” on previously developed land.
“Under the Trump administration’s direction, [the LPO] can use that term, ‘known and forecastable,’ to actually just say, well, guess what? Renewables are not known or forecastable because they are intermittent due to the weather,” Arun told me. So while government and private industry were once excited about, say, turning sites originally developed for coal mining or coal ash disposal into solar and battery facilities, those days are probably over.
Carbon capture in particular stands to suffer from this reprogramming, Arun said, explaining that while the Biden LPO saw potential in adding carbon capture to natural gas and coal plants, its current incarnation will no longer allocate funding in any meaningful amount “because reducing emissions is no longer part of the LPO’s mandate.” Some policymakers and clean energy developers had also hoped that excess renewable energy would make it economically feasible to power the production of hydrogen fuel with renewable energy. But with this law — and really each passing day under Trump — a mass buildout of solar and wind seems less and less likely, making it doubtful that green hydrogen will move down the cost curve.
As bleak as this looks, it’s better than it could have been. There was no guarantee that Trump would keep the LPO around at all. Even in this denuded state, the office can still fund the expansion of existing nuclear projects, and perhaps even the buildout of transmission lines or battery projects on brownfield sites, Arun said, depending on how LPO’s leadership ends up interpreting what it means to “increase the capacity output of operating infrastructure.”
But in many ways, what happened with the LPO looks like another instance of the Trump administration picking winners and losers: Yes to clean, firm energy and fossil fuels, no to solar, wind, and electric vehicles.
Take the Advanced Technology Vehicle Manufacturing Program, for example. OBBBA nixed both its credit subsidies and its tens of billions of dollars in lending authority. That’s hardly a surprise, given that the Bush administration created the program in 2007 explicitly to support the domestic development and manufacture of fuel-efficient vehicles and components. But it means that unlike the LPO programs for which lending authority still stands, even if Congress wanted to, it could not redesign the advanced vehicles program to serve a more Trump-aligned purpose. Safer, I suppose, to cut off any opening for funding EVs and hybrids.
The latest LPO rescissions add to the growing list of reasons the private sector has to be wary of the consistently inconsistent landscape for federal funding, Arun told me. He worries that slashing the LPO’s authority at the same time as there’s so much uncertainty around tax credit eligibility will lead some companies to forgo federal funding opportunities altogether.
“We’ll see if private developers even want to play around with the LPO,” Arun told me, “given the uncertainty around the rest of the federal landscape here.”

This year’s ocean-heating phenomenon could make climate change seem less bad than it really is — at least in the U.S.
You may have heard that we could be in for a “super” or even a “super duper” El Niño this year. The difference is non-technical, a matter of how warm the sea surface temperature in the El Niño-Southern Oscillation region of the central-eastern Pacific Ocean gets. An El Niño forms when the region is at least half a degree Celsius warmer than average, which causes more heat to be released into the atmosphere and affects global weather patterns. A super El Niño describes an anomaly of 2 degrees or higher. Some models predict an anomaly of over 3 degrees higher than average for this year.
If a super El Niño forms — and that is still a big if, about a one-in-four chance — it would be the fourth such event in just over 40 years. But the impacts could be even more severe, simply because the world is hotter today than it was in the previous super El Niño years of 1983, 1998, and 2016.
“2016 would be an unusually cold year if it occurred today,” Zeke Hausfather, the climate research lead for payment processing giant Stripe and a research scientist at Berkeley Earth, told me. “1998 would be exceptionally cold.”
And yet in a strange twist, a 2026-2027 El Niño event might actually make Americans care less about climate change. Though many parts of the world are likely to get clobbered by El Niño’s characteristic combination of hotter, drier weather, the phenomenon has the potential to alleviate some of the extreme weather we’ve seen recently in the United States.
For example, warmer, wetter conditions in the southern U.S., milder winters in the north, and increased wind shear in the Atlantic hurricane basin are all classic El Niño signatures in North America.
“It may actually mean a better snow season for the Western U.S. and the mountains, hopefully recovering our snowpack if it’s not too warm,” Hausfather said. “We might benefit from higher rainfall” next winter, which could help lift widespread drought conditions in the southwest. High wind shear usually results in reduced hurricane activity in the Atlantic by depriving the storm systems of their heat engines and causing them to be too lopsided to organize into a full-blown cyclone.
Though the body of evidence for climate change remains incontrovertible, the temporary reprieve in some of its more visible effects will almost certainly make some Americans less concerned. Blame it on evolutionary biology. Brett Pelham, a social psychologist at Montgomery College who researches egocentrism and biases, told me that humans are hardwired to pay attention to the conditions happening directly around them. “That’s great if you’re living 20,000 or 80,000 years ago,” he said. “But today, we’re pumping tons of greenhouse gases into the atmosphere, and it’s a recipe for disaster because people only care deeply about that problem if they feel the heat on a pretty chronic basis where they live.”
People are generally less likely to believe the planet is warming on a snowy day in March than they are in the summer, and a lower average state temperature is about as reliable a predictor of climate change skepticism as being a Republican, even when controlling for income, party affiliation, education, and age. Given that it is, in theory, easier to convince someone living in scorching hot Phoenix that greenhouse gases are warming the atmosphere than someone living by a lake in Minnesota, if an El Niño mellows out some extreme weather trends in the U.S. this year and next, it could also mellow some of the sense of urgency to act.
“It’s a definite implication of my work that day-to-day variation, monthly variation, and geographical variation matter,” Pelham said.
“If my data are true,” he added, “it’s going to be true on average that in places that have an unseasonably cool summer or winter, there’s going to be a temporary shift in the average attitude.”
Such shifts affect the average by just a few points either way — “they’re not night and day, like ‘I believed in climate change and now I don’t,’” Pelham stressed. But it’s undoubtedly ironic — and concerning — that heading into what could be one of the hottest years on the planet in recent history, Americans may be predisposed to feeling relatively safe.
Other parts of the world won’t have such luxury. Even a normal-strength El Niño, which looks all but certain to form this year, could cause major damage, from wildfires in parched Indonesia to catastrophic floods in East Africa to water rationing in South America. In Peru and Ecuador, El Niño is already a “current event,” Ángel F. Adames Corraliza, an atmospheric researcher at the University of Wisconsin-Madison and a 2025 MacArthur Fellow, told me. Warm coastal conditions off the continent — a known, albeit not guaranteed, global El Niño precursor — are causing deluges, landslides, and heat waves in the upper northwest corner of South America. “You can see how the impacts start extending towards other parts of the world until it reaches us,” he said.
It is possible to combat local biases. Pelham told me other researchers have found that images can break through our egocentrism. So “if we see more pictures of melting glaciers or waters rising in our own backyards, we would start to say, ‘Oh my goodness, we really have to do something about this global problem,” he said.
But to that end, coverage of climate change that might have this effect is becoming rarer. Stories about global warming have dropped about 38% since 2021; even people working in climate-related industries have “a kind of exhaustion with ‘climate’ as the right frame through which to understand the fractious mixture of electrification, pollution reduction, clean energy development, and other goals that people who care about climate change actually pursue,” my colleague Robinson Meyer wrote based on the results of latest Heatmap Insiders Survey.
Of course, there is no promise that the U.S. will skirt disaster because of El Niño. Increased rainfall means more floods and landslides; if the El Niño pushes temperatures up too high, snowpack will once again be an issue next winter. All it takes is one big hurricane forming and making landfall for it to be considered a bad storm year, which is as much a roll of the dice as anything else. And because El Niño releases ocean heat into the atmosphere, the periods immediately following it are often about two-tenths of a degree Celsius warmer, increasing the severity of heat waves and droughts. Compounded by climate change, that puts 2027 on track to be potentially the hottest year the planet has seen in human history.
“We might be at 1.45 degrees Celsius [above preindustrial levels] next year from human activity, and we might end up at 1.65 degrees because there’s a very strong El Niño,” Hausfather said. But for context, “we are seeing that much warmth added to the climate system from human activity roughly every decade,” he told me. That is, “— we’re adding a permanent super El Niño-worth of heat to the climate system” via the continued burning of fossil fuels.
There couldn’t be a worse time to let up on our collective sense of climate urgency, to put it mildly. But if El Niño makes conditions in the U.S. appear any better, then even if there’s disaster elsewhere, “you’re going to give a sigh of relief,” Pelham predicted. “You’re going to feel like [climate change is] not as bad as people have hyped it up to be.”
Current conditions: Wildfires are raging across the Southeast, with more than 27,000 acres alight in southern Georgia alone • At least two separate blazes have also broken out in Japan’s northeastern Iwate prefecture • A late blizzard is dumping as much as 20 inches of snow on northern Manitoba, Canada.
Yet another French energy giant is lining up for a payout from the Trump administration to abandon its offshore wind projects in the United States. Utility giant Engie is in talks with the federal government about a “possible refund” for its U.S. offshore wind leases as President Donald Trump looks to halt expansion of an energy source that’s quickly growing in Europe and Asia. Since Trump returned to office last year, the company has paused development on three offshore wind projects and already took a loss on its joint venture Ocean Winds. In an interview with Reuters, Engie CEO Catherine MacGregor confirmed that the utility was pursuing the kind of deal that French oil and gas giant TotalEnergies negotiated in recent weeks. “We’ll see about these terms. An agreement is possible depending on the discussions.” She noted that she wasn’t against offshore wind. “Economically and also in terms of public acceptance, I strongly believe in offshore wind power. Of course, you have to plan the projects well, you have to involve the fishermen,” she added. Still, “new offshore wind projects are going to be complicated regardless of the administration.”
The $1 billion TotalEnergies deal may also stand on shaky ground. As Heatmap’s Emily Pontecorvo reported in back-to-back scoops, documents suggest the Trump administration’s legal argument for drawing on a federal settlement fund rests on shaky ground. Other documents show that TotalEnergies isn't required to make any new investments in U.S. oil and gas under the agreement, contrary to what Trump officials said about the deal.

Long accused of maintaining an overcapacity of factories to churn out solar panels, China’s photovoltaic output is now in soaring demand as the world scrambles to cope with the energy shock brought on by the Iran War’s closure of the Strait of Hormuz. New data from the think tank Ember shows that China’s solar exports reached a record 68 gigawatts in March, double the previous month. When Ember analyzed the Chinese customs authority data, its researchers found that the exports are equivalent to Spain’s entire solar capacity, surpassing the previous record set in August 2025 by 49%. At least 50 countries — you read that right — set all-time records for Chinese solar imports in March, with another 60 seeing the highest levels in six months. Compared to February numbers (the war began on February 28), Chinese solar exports grew by 141% to India, 384% to Malaysia, 391% to Ethiopia, and 519% to Nigeria.
“Fossil shocks are boosting the solar surge,” Euan Graham, senior analyst at Ember, said in a statement. “Solar has already become the engine of the global economy, and now the current fossil fuel price shocks are taking it up a gear. Countries are importing solar panels at record levels, and building up their own domestic assembly and manufacturing capabilities to address surging global demand.”
Elon Musk is betting even bigger on artificial intelligence. Tesla plans to boost spending to $25 billion this year as the electric automaker cum battery and solar giant invests in self-driving taxis, zero-emissions trucks, robots, and a sweeping new chip factory to power its AI ambitions. During a call with investors on Thursday, Musk said there would be a “very significant increase in capital expenditure” this year, which “will be well justified considering substantially increased revenue streams,” according to the Financial Times. The forecast is nearly triple the $8.5 billion Tesla spent last year.
The shift comes as the U.S. faces what Heatmap contributor Andrew Moseman called the “great American EV contraction” that took place after the Trump administration ended federal tax credits for electric vehicles last fall.

In a nuclear industry filled with startups promising to reinvent the reactor, Blue Energy stands out as a company promising instead to transform how good old-fashioned light water reactors are built. The firm wants to prefabricate its small modular reactors in a factory, making each one as uniform and replicable as possible. “For the first time, a nuclear project is designed so that it doesn’t need to rely primarily on taxpayer dollars and ratepayers to backstop risk,” Jake Jurewicz, Blue Energy chief executive and co-founder, told S&P Global. In a press release, Jurewicz called its forthcoming debut facility, a 1.5-gigawatt complex in Texas, “the first project-financeable nuclear plant.”
Shares in GE Vernova spiked 14% on Wednesday after the energy industrial giant reported surging demand for its gas turbines and nuclear reactors to power the AI boom in its latest quarterly earnings. As I told you yesterday, GE Vernova’s head of government affairs and policy, Roger Martella, said this week that the project to build North America’s first small modular reactor at Ontario Power Generation’s Darlington plant was on track to produce power by 2030. In a note to investors, the investment bank Jeffries said soaring gas demand and “green-shoots for nuclear” sent the price upward.
If online gambling services like Kalshi and Polymarket allow people to bet on something, do the incentives for the worse outcome change? Turns out, obviously, the answer is yes. Just consider this example. Polymarket allowed people to bet on daily temperatures from some official weather stations. Now Météo-France, the official French meteorological agency, is accusing someone of using an artificial heat source to manipulate reads at a station and win bets.
Rob dives into Fervo’s S-1 filing with Princeton professor Jesse Jenkins and Heatmap’s Matthew Zeitlin.
Fervo Energy has become a darling of the clean energy industry by using workers and technology from the oil and gas sector to unlock zero-carbon, all-day geothermal electricity. Last week, Fervo filed to go public, giving us the first deep look at its finances and long-term expansion plans. What’s the bull case, the bear case, and the fine print?
On this week’s episode of Shift Key, Rob is joined by Jesse Jenkins, a professor of energy systems engineering at Princeton University, as well as Heatmap’s Matthew Zeitlin to discuss the big news from Fervo’s new filing. Why are people so excited about Fervo? What are the biggest financial questions in its growth plans? And why does it need to go public now?
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap News.

Here is an excerpt of their conversation:
Robinson Meyer: Jesse, one of the things that people are most excited about with Fervo — and one of the things, frankly, that you got me excited about with regard to Fervo and other enhanced geothermal companies — is that this is dispatchable power. It’s not only that it’s 24-7, but much like like we currently flex gas plants up or down to meet demand on the grid, we might be able to flex geothermal plants up and down. Can you just describe like how that would work and why it’s important to kind of overall value of this energy technology?
Jesse Jenkins: Yeah, so most people think of geothermal as a kind of zero marginal cost resource. It has no fuel cost, right? It’s producing power that’s on the margin, basically free. And so it would make sense to operate it like a “baseload resource” running 24-7, because why would you ever turn off?
The reality is that if you are deploying geothermal in a world with lots of cheap solar, for example, or wind in other parts of the West, there are many hours when power is literally worthless or very inexpensive, right? You’ve got wind and solar flooding the market at also zero marginal cost. And so producing power in those hours, you can do it, but why would you? It’s not valuable. When it’s valuable is the times when the sun is setting and the wind is dying down and you would otherwise have to fire up gas power plants.
So one of the cool things about enhanced geothermal is that you’re basically engineering a fracture network inside a very impermeable rock, right? You basically have a container around it of granite. And that means that very little fluid or pressure will leak out of the reservoir if you inject more fluid into it. And so you’ve basically built yourself a pumped hydrate reservoir underground for free, because that’s what you needed to create your heat exchanger to get the heat out for your power plant.
