Whether they can continue to do so depends on how long the green freeze lasts.

This story is part of a Heatmap series on the “green freeze” under Trump.
By now I’ve come to expect the responses. “We’re continuing to assess the situation and aren’t able to speak on it at this time.” “We are not able to provide comment on this matter.” Oftentimes, all I’ll receive is a Gmail prompt to an unanswered email: Sent 9 days ago. Follow up?
This week, my colleagues and I are covering the “green freeze,” an economy-wide trend of canceled clean energy projects, a retreat from climate tech investments, and a tightening of purse strings perhaps best epitomized by Breakthrough Energy’s pullback from grantmaking and policy advocacy. I aimed to look more closely at how nonprofits are navigating the new political and economic landscape — with climate no longer a key policy focus of the White House, would related causes lose their appeal to donors? Or would the opposite be true: Given the federal funding gap, would philanthropy surge to fill the vacuum? Would it even be prudent to do so?
“In my experience, when the government takes a step back from a particular impact area — and climate is no different — often philanthropists end up leaning in,” Amy Duffuor, a co-founder and partner at Azolla Ventures, told me. Azolla invests in climate tech start-ups using both traditional venture capital and catalytic capital, the latter of which comes primarily from philanthropists. But for many organizations, especially at the grassroots level or in the environmental justice space, it might not be that simple.
Talking about donors is always delicate and awkward, but I was still surprised by how closed-lipped local and national nonprofits became when I started asking these questions. Many groups that have spoken candidly with Heatmap News in the past declined to talk to me on the topic, even on background. One media relations manager for a conservation organization that receives federal grants delicately implied, while turning down my request for comment, that no one wants to stick their neck out when there’s a climate witch-hunt going on.
“Nonprofits have to be really conscious of where their support comes from and how they protect that,” Cyrus Wadia, the CEO of Activate, a nonprofit that offers fellowship support for early-stage science entrepreneurs looking to launch climate start-ups, told me when I explained what I was seeing.
He’s right that the wariness is understandable. The Trump administration is attempting to claw back some $20 billion in funds awarded to climate nonprofits under President Joe Biden, including hundreds of grants from the Environmental Protection Agency, many of which were earmarked for local environmental justice nonprofits. A number of these nonprofits are, as a result, facing unexpected funding shortfalls, forcing them to consider cuts to staff and programs in the weeks and months ahead. “If this lasts much longer … then we’re going to start seeing more organizations saying this program and that program have to shut down, they’re having to reduce capacity because they can’t make payroll, or they’re closing their doors,” Rick Cohen, the chief communications officer for the National Council of Nonprofits, recently told The Chronicle of Philanthropy.
There is a sense among some in the nonprofit space that the hesitation among donors might be more of a reassessment than an actual freeze. “There is definitely a ‘pause and wait and see and figure out our strategy and maybe start over’ moment that I think a couple of these foundations are having,” Lara Pierpoint, the managing director of Trellis Climate — a 501(c)(3) that helps philanthropists, donors, and foundations invest in climate opportunities that wouldn’t go forward without philanthropic support — told me. A policy director for a national policymaking and advocacy group similarly suggested to me that the election of Trump caught some of their donors flat-footed, adding that they “didn’t have strategies ready to go.”
That doesn’t necessarily indicate a broader trend. “The good news is that we aren’t seeing a huge amount of change just yet among our donor set,” she told me. “I think our donor set tends to be folks who are already very focused on climate,” she went on. “They are not only not afraid of the word ‘climate,’ but I think they really see the need to focus on it, particularly given what’s going on.”
She did note, however, that it’s still early, and that there are two main headwinds she and her peers are facing. “Some of the donors that we’ve spoken to have said, ‘Hey, we can’t really talk right now or commit to anything because we’re doing a wholesale reevaluation of our portfolio and how we approach giving,’” she said. Additionally, philanthropists who think of themselves more as investors might have questions about how viable their investments will be, given what’s happening with both federal priorities and the gyrating economy.
As my colleague Katie Brigham has reported, climate tech investment had already started to slow down from the frothy days of the early Biden administration; some companies had started to pivot away from promoting the clean, green climate perks of their business models even before Trump took office. (Bloomberg has labeled this semantic game “greenhushing”; the general wisdom is, “it’s still a great time to start a climate startup. Just don’t call it a climate startup.”) Anxieties about the economy can, as a rule, also impact the giving patterns of donors.
“At the end of the day, for very good reasons, philanthropists want to invest in projects and ideas that are likely to be successful and go forward and do the things they are meant to do,” Pierpoint said. “And all of that is under threat right now because climate tech is hard, it’s expensive, it’s competing with fossil fuels, and counting out government support and tax credits, the picture is daunting.”
Others were similarly cautiously optimistic about the days ahead. “There’s a gap, and philanthropy is often well-suited to close gaps,” said Duffuor, the partner at Azolla Ventures. (Both Azolla Ventures and Trellis Climate are part of Prime Coalition, a nonprofit focused on climate financing.)
Like Pierpoint, Duffuor expects to see a “doubling down” by philanthropists who are motivated by climate. Donors who were more on the cusp to begin with — who saw climate investment as en vogue, or were more driven by financial returns — might back away, she agreed. But it seems unlikely that people who genuinely believe in climate causes will be dissuaded by who’s in the White House. “I think people are waiting to see where the gaps are most effective,” she said.
Wadia, the CEO of the venture capital firm Activate, who spoke with me from the CERAWeek energy conference in Houston, agreed that while the language around giving may change, he is still seeing a “momentum for innovation.”
“If we all just step back, what are we really trying to do?” he said, speaking of nonprofits, philanthropists, and start-ups alike. “Everybody might have a different version of how we do it, but we’re all working towards trying to make the planet a better place for people — for all species on this planet. There’s a general consensus that’s a good thing.”
The nonprofit sector is large and diverse, and the impacts of the political and economic moment will not be felt equally. Local environmental justice nonprofits that relied on federal grants will undoubtedly be worse off than the better-insulated climate financing organizations like Activate, although the turbulence at Breakthrough suggests that even the deepest of pockets can still close to climate causes. (Tellingly, companies funded by Breakthrough’s investment arm, Breakthrough Ventures, do not appear to be affected.) The tension and anxiety aren’t likely to break soon; uncertainty and fear remain pervasive.
If anything can be counted on, though, it’s that climate causes — whether local, national, community-focused, or innovation-related — will need their donors more than ever. The people I spoke with expect them to step up. But is that even a good thing?
“It’s not just the immediate impact — the question mark around grant funding and things like that,” Pierpoint of Trellis Climate told me. “It’s also the question of, is this, in the long term, going to reduce trust in the federal government in a way that lowers investment when folks are trying to leverage dollars?” She paused. “I think it would be bluntly catastrophic for climate development if we get into that world.”
Editor’s note: This story has been updated to reflect the fact that Activate is a nonprofit, not a venture capital firm.

On China’s H2 breakthrough, vehicle-to-grid charging, and USA Rare Earth goes to Brazil
Current conditions: In the Atlantic, Tropical Storm Fernand is heading northward toward Bermuda • In the Pacific, Tropic Storm Juliette is active about 520 miles southwest of Baja California, with winds of up to 65 miles per hour • Temperatures are surging past 100 degrees Fahrenheit in South Korea.
Nearly two weeks ago, Vineyard Wind sued one of its suppliers, GE Vernova, to keep the industrial giant from exiting the offshore wind project off the coast of Nantucket in Massachusetts. Now a U.S. court has ordered GE Vernova to finish the job, saying it would be “fanciful” to imagine a new contractor could complete the installation. GE Vernova had argued that Vineyard Wind — a 50/50 joint venture between the European power giant Avangrid and Copenhagen Infrastructure Partners — owed it $300 million for work already performed. But Vineyard Wind countered that the manufacturer remains on the hook for about $545 million to make up for a catastrophic turbine blade collapse in 2024, according to WBUR. “The project is at a critical phase and the loss of [Vineyard Wind]’s principal contractor would set the project back immeasurably,” the Suffolk County Superior Court Judge Peter Krupp wrote in his decision, repeatedly using the name of GE Vernova’s renewables subsidiary. “To pretend that [Vineyard Wind] could go out and hire one or more contractors to finish the installation and troubleshoot and modify [GE Renewables’] proprietary design without [GE Renewables’] specialized knowledge is fanciful.”
Charlotte DeWald fears the world is sleepwalking into tipping points beyond which the Earth’s natural carbon cycles will render climate change uncontrollable. By the time we realize what it means for global weather and agricultural systems that there’s no sea ice in the Arctic sometime in the 2030s, for example, it may be too late to try anything drastic to buy us more time. Much of the discourse around what to do concerns a specific kind of geoengineering called stratospheric aerosol injections, essentially spraying reflective particles into the sky to block the sun’s heat from permeating the increasingly thick layer of greenhouse gases that prevent that energy from naturally radiating back into space. That’s something DeWald, a former Pacific Northwest National Laboratory researcher and climate scientist by training who specialized in modeling aerosol-cloud interactions, knows all about. But her approach is different, using a technology known as mixed-phase cloud thinning, a process similar to cloud seeding. “The idea is that you could dissipate clouds over the Arctic to release heat from the surface to, for example, increase sea ice extent or thickness or integrity,” she told me. “There’s some early modeling that suggests that it could yield significant cooling over the Arctic Ocean.”
With all that context, you can now appreciate the exclusive bit of news I have for you this morning: DeWald is launching a new nonprofit called the Arctic Stabilization Initiative to “evaluate whether targeted interventions can slow dangerous” warming near the Earth’s northern pole. So far, ASI has raised $6.5 million in philanthropic funding toward a five-year budget goal of $55 million to study whether MCT, as mixed-phase cloud thinning is known, could help save the Arctic. The nonprofit has an advisory board stacked with veteran Arctic scientists and put together a “stage-gated” research plan with offramps in case early modeling suggests MCT won’t work or could cause undue environmental damage. The project also has an eye toward engaging with Indigenous peoples and “will ground all future work in respect for Indigenous sovereignty, before any field-based research activity is pursued.” The statement harkens to Harvard University’s SCoPEx trial, a would-be outdoor experiment in spraying reflective aerosols into the atmosphere over Sweden that ran aground after researchers initially failed to consult local stakeholders and a body representing the Indigenous Saami people in the northern reaches of Nordic nations came out against the testing. (By repeatedly invoking ASI’s nonprofit status, DeWald also seemed to draw a contrast with for-profit stratospheric aerosol injection startup Stardust Solutions, which last year Heatmap’s Robinson Meyer reported had raised $60 million.) “We are continuing to move toward critical planetary thresholds without a bible plan for things like tipping points,” DeWald said. “That was the inflection point for me.”

China just took yet another step closer to energy independence, despite its relatively tiny domestic reserves of oil and gas, kicking off the world’s largest project to blend hydrogen into the natural gas system. As part of the experiment, roughly 100,000 households in the center of the Weifang, a prefecture-level city in eastern Shandong province between Beijing and Shanghai, will receive a blend of up to 10% hydrogen through existing gas pipes. The pilot’s size alone “smashes” the world record, according to Hydrogen Insight. Whether that’s meaningful from a climate perspective depends on how you look at things. A fraction of 1% of China’s hydrogen fuel comes from electrolyzer plants powered by clean renewables or nuclear electricity. But the People’s Republic still produces more green hydrogen than any other nation. Last year, the central government made cleaning up heavy industry with green hydrogen a higher priority — a goal that’s been supercharged by the war in Iran. Therein lies the real biggest motivator now. While China relies on imports for natural gas, swapping out more of that fuel for domestically generated hydrogen allows Beijing to claim the moral high ground on emissions and air pollution — all while becoming more energy independent.
Meanwhile, China’s container ships are the latest sector to experiment with going electric and forgoing the need for costly, dirty bunker fuel. A 10,000-ton fully electric cargo vessel capable of carrying 742 shipping containers just started up operations in China this week, according to a video posted on X by China’s Xinhua News service.

The ability of electric vehicles to serve as distributed energy resources, charging in times of low demand and discharging back onto the grid when demand peaks, has long been a dream of EV enthusiasts and DER advocates alike. California’s PG&E utility launched a small bi-directional charging program in 2023, allowing owners of Ford F-150 Lightnings to use their trucks as home backup power, and eventually feed energy back onto the grid. The utility added a host of General Motors EVs to the program back in 2025. On Monday, it announced its latest vehicle participant: Tesla’s Cybertruck. The Tesla vehicle will be the first in the program to run on alternating current, which simplifies the equipment necessary and lowers costs for consumers, according to PG&E’s announcement.
In January, I told you about the then-latest company to benefit from President Donald Trump’s dabbling in what you might call state capitalism with American characteristics: USA Rare Earth. The vertically integrated company, which aims to mine rare earths in Texas, took big leaps forward in the past year toward building factories to turn those metals into the magnets needed for modern technologies. For now, however, the company needs ore. On Monday, USA Rare Earth announced plans to buy Brazilian rare earth miner Serra Verde in a deal valued at $2.8 billion in cash and shares. The transaction is expected to be complete by the end of the third quarter of this year. The company pitched the move as a direct challenge to China, which dominates both the processing of rare earths mined at home and abroad. “The world has become too dependent on a single source and it’s high time to break that dependency,” USA Rare Earth CEO Barbara Humpton told CNBC’s “Squawk Box” on Monday.
As if we needed more evidence that the data center backlash is “swallowing American politics,” here’s Heatmap’s Jael Holzman with yet another data point: According to tracking from the Heatmap Pro database, fights against data centers now outnumber fights against wind farms in the U.S. That includes both onshore and offshore wind developments. “Taken together,” Jael wrote, “these numbers describe the tremendous power involved in the data center wars.”
Fights over AI-related developments outnumber those over wind farms in the Heatmap Pro database.
Local data center conflicts in the U.S. now outnumber clashes over wind farms.
More than 270 data centers have faced opposition across the country compared to 258 onshore and offshore wind projects, according to a review of data collected by Heatmap Pro. Data center battles only recently overtook wind turbines, driven by the sudden spike in backlash to data center development over the past year. It’s indicative of how the intensity of the angst over big tech infrastructure is surging past current and historic malaise against wind.
Battles over solar projects have still occurred far more often than fights over data centers — nearly twice as many times, per the data. But in terms of megawatts, the sheer amount of data center demand that has been opposed nearly equals that of solar: more than 51 gigawatts.
Taken together, these numbers describe the tremendous power involved in the data center wars, which is now comparable to the entire national fight over renewable energy. One side of the brawl is demand, the other supply. If this trend continues at this pace, it’s possible the scale of tension over data centers could one day usurp what we’ve been tracking for both solar and wind combined.
The enhanced geothermal darling is spending big on capex, but its shares will be structured more like a software company’s.
Fervo, the enhanced geothermal company that uses hydraulic fracturing techniques to drill thousands of feet into the Earth to find pockets of heat to tap for geothermal power, is going public.
The Houston-based company was founded in 2017 and has been a longtime favorite of investors, government officials, and the media (not to mention Heatmap’s hand-selected group of climate tech insiders) for its promise of producing 24/7 clean power using tools, techniques, and personnel borrowed from the oil and gas industry.
After much speculation as to when it would go public, Fervo filed the registration document for its initial public offering on Friday evening. Here’s what we were able to glean about the company, its business, and the geothermal industry from the filing.
The main theme of the document, known as an S-1, is the immense potential enhanced geothermal — and, thus, Fervo — has.
The company says that its Cape Station site in Utah, where it’s currently developing its flagship power plants, had “4.3 gigawatts of capacity potential” alone. That’s more than the 3.8 gigawatts of conventional geothermal capacity currently on the grid. Enhanced geothermal technology, otherwise known as EGS, “has the potential to make geothermal generation as ubiquitous as solar generation is in the U.S. today,” the company projects. (There’s about 280 gigawatts of installed solar capacity currently in the U.S., according to the Solar Energy Industries Association) “A broader subset of our reviewed leases represents over 40 gigawatts” of capacity, the document goes on.
Like all investor pitches, the S-1 features some eye-popping “total addressable market” figures. Citing analysis by the consulting firm Rystad, the document says that if there’s a sufficient shortfall in capacity due to retiring power plants (98 gigawatts by 2035), the annual market for enhanced geothermal would be approximately $70 billion by 2035, and that this would represent some $2.1 trillion in revenue potential over 30 years.
The company is already producing 3 megawatts at its Nevada Project Red site for the Nevada grid as part of a deal with Google. It also expects to begin generating power from the Cape Station site “by late 2026,” according to the filing, and get up to 100 megawatts “by early 2027.” In total, Fervo has “658 megawatts of binding power purchase agreements,” which it says represents ”approximately $7.2 billion in potential revenue backlog.”
Beyond that, Fervo says it has 2.6 gigawatts “in advanced development,” and “over 38 gigawatts” in “early-stage development,” where it’s still doing feasibility studies to “validate and confirm the path toward commercial development.”
Fervo says that the energy produced from its Cape Station facility will come in at around $7,000 per kilowatt. That’s already cheaper than “traditional and small modular nuclear power,” which the Department of Energy has estimated costs $6,000 to $10,000 per kilowatt, the filing says. Fervo is aiming to get the total project costs down to $3,000 per kilowatt, at which point it says it would outcompete natural gas without any of the price volatility due to fuel costs going up and down.
But Fervo’s upfront spending is still immense. Fervo says that it expects some $1.2 billion in capital expenditure this year, of which only $125 million is going toward the first phase of its Cape Station project, which it has said would deliver 100 megawatts of power. (Meanwhile, the $940 million it expects to spend on the second phase, which is due to be 400 megawatts, is mostly unfunded.) The company says the public offering will fund “project-level capital expenditures,” as well as land holdings and general corporate expenditures.
Google comes up some 36 times in the document, most times in reference to the “Geothermal Framework Agreement” Fervo signed with the hyperscaler this past March. The S-1 describes the deal as a “3-gigawatt framework agreement … to advance and structure potential power offtake opportunities for current and planned data centers in both grid-connected and alternative energy solutions.” This deal, the company says, “establishes a structured process for the development of geothermal projects across specified regions of the United States,” and could involve the offtake by Google of up to 3 gigawatts of Fervo-generated electricity by the end of 2033.
What the framework is not is a power purchase agreement. One of the risk factors Fervo lists in the IPO document says, “The GFA is a non-binding agreement, and does not obligate Google to purchase power from us.” Instead, it is “a binding framework under which we may propose geothermal development projects to Google, but it does not obligate Google to accept any project, execute any power purchase agreement or provide us with any project financing.”
The agreement also places limits on Fervo, including from whom it can accept investment or financing. (The deal outlines a “broad category of entities defined as competitors,” which are all no-nos.) Overall, the company says, the arrangement gives Google “significant priority over our near-term development pipeline and may limit our flexibility to pursue alternative commercial, strategic, or financing arrangements that would otherwise be available to us.”
Upon going public, the company will have two shares of stock: Class A shares available to the public, and Class B shares owned by its founders, chief executive officer Tim Latimer, and chief technology officer Jack Norbeck. These Class B shares will have 40 times the voting rights of the class A shares and will allow Latimer and Norbeck to “collectively continue to control a significant percentage of the combined voting power of our common stock and therefore are able to control all matters submitted to our stockholders for approval.”
These arrangements are familiar with venture-backed, founder-led software companies. Alphabet and Meta are the most prominent examples of large, publicly traded companies that are under the effective control of their founders thanks to dual class share structures. Tesla, rather famously, does not have a dual class share structure, which is why CEO Elon Musk convinced his board to award him more shares so that he would maintain a high degree of influence over the company.
While other technology companies such as Stripe pile up billions in revenue without any near term prospects of going public, Fervo largely has spending to report on its income statement.
In 2025, the company reported just $138,000 in revenues with a $58 million net loss; that’s compared to a $41 million net loss in 2024. The revenues were “ancillary fees associated with rights to geothermal production at Project Red,” the company said. “This type of revenue is not expected to be significant to our long-term revenue generation, as we have not yet commenced large-scale commercial operations.”
And there’s more spending to come.
Fervo expects that the second phase of its Cape Station project will “require approximately $2.2 billion in capital expenditures through 2028,” which it hopes to pay for with project-level financing.
Fervo said it is “continuing to evaluate the effect of the OBBB” — that is, the One Big Beautiful Bill Act, which slashed or curtailed tax credits for clean energy companies — and that it wasn’t able to “reasonably” estimate the effect on its financial statements by the end of last year. The company does say, however, that it “may benefit from ITCs and PTCs (including the energy community and domestic content bonuses available under the ITC and PTC, in certain circumstances) with respect to qualifying renewable energy projects,” referring to the investment and production tax credits, which acquired a strict set of eligibility rules under OBBBA. It cautioned that the current guidance regarding tax credit eligibility is “subject to a number of uncertainties,” and that “there can be no assurance that the IRS will agree with our approach to determining eligibility for ITCs and PTCs in the event of an audit.”
The company also disclosed that earlier this month, it reached a deal with Liberty Mutual, the insurance company “to sell and transfer tax credits generated at Cape Station Phase I,” taking advantage of a provision of the law that allows credits to be sold to other entities with tax liability, and not just harvested by investors in the project.
