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.

The Iran war has been a gift to the country’s vehicle, solar, and battery business.
This is Heatmap Daily, a weekday evening digest written by our executive editor.
Happy Monday and welcome back. For months now, we’ve been talking about how the U.S. and Israel’s war in Iran has been a boon for electric vehicles, clean energy, and (unfortunately) coal.
But today we got data that confirms: This clean energy export boom is not just a side story. It is one of the brighter spots in the overall Chinese economy, which remains the world’s second largest.
According to economic data released on Monday, China grew 4.5% during the summer quarter as compared to the quarter from a year earlier. That means the country will likely hit its growth target this year, albeit on the low end.
The country’s economic expansion wasn’t driven by domestic consumption, however. Consumer confidence remains low, and residential investment has yet to return after the property crash earlier this decade.
Instead, booming exports are now driving China’s economy. Exports were more than 36% higher in September than a year earlier, driven by chips, ships, electric vehicles, and solar panels and batteries. The country will likely record its biggest trade surplus ever this year.
Some of those categories are clearly flourishing thanks to the global AI boom — think chips and even batteries. But the preponderance of vehicle exports suggests surging oil prices aren’t hurting. Sales of ‘new energy vehicles,’ a category that includes 100% electric vehicles and plug-in hybrids, were up more than 13% on a year-over-year basis in September, according to the Chinese car manufacturer’s trade group. But exports of these vehicles are booming. Battery electric vehicles were up 130% last month compared to the same period in 2025, and plug-in hybrid exports were up more than 200%.
It’s interesting to consider how much the Chinese and U.S. economy are mirroring each other at this moment. Americans are dealing with a remarkable investment boom, which is buoying the labor market and stubbornly maintaining high inflationary pressure. China is struggling with deflation, and exports are its quickest path to growth. (Consumer sentiment in both countries, interestingly, seems to be in the doldrums, even though American consumers appear to be in much better shape.)
When thinking about what artificial intelligence could do for the United States over the next decade, some subject-matter prognosticators (and even some Anthropic employees) imagine a world of 4%, 5%, or even 7% GDP growth. Such a growth rate is difficult even to envision in the modern era, of course, and it seems like it could propel the U.S. economy to staggering prosperity.
I know better than to make a prediction about where we’re headed. But amateur economic commentators should keep China in mind, too: a country that dominates along many technological axes, but where the standard economic math of supply, demand, and consumer sentiment still holds. Except if the United States economy were to stumble, no exterior source of demand will come to our rescue.
Endurance Energy hoped its generator would run for a full year, but the team isn’t afraid of the “error” in “trial and error.”
About 300 miles off the Oregon coast, a mile beneath the ocean’s surface, a startup just drilled the world’s first subsea geothermal well. And for a grand total of exactly 8.7 seconds, its prototype power plant generated about 2 kilowatts of net power. It wasn’t quite the result the Seattle-based Endurance Energy was hoping for — the company’s goal was to run its 100-kilowatt generator for a full year. But it’s not nothing.
“We really proved with this mission that a geothermal well could be drilled and completed on the seafloor, and doing that within 21 months of the company existing I think is really a testament to our pace of progress,” Endurance CEO Andrew Redd told me.
A former SpaceX engineer — as so many climate tech founders seem to be — Redd appears quite comfortable with the rapid trial-and-error cycles that hard tech startups often demand. Or as he stated in the company’s press release, which provides a refreshingly frank account of what this first test did and didn’t accomplish, “We follow the adage ‘make it exist, then make it good.’”
Investors seem to be buying it. In June, the startup raised a $54 million Series A, led by Peter Thiel’s Founders Fund — Endurance’s second funding round in less than two years of existence. Still, the team certainly has their work cut out for them. The ocean is a notoriously difficult operating environment: Saltwater is corrosive and offshore infrastructure is difficult and expensive to build, maintain, and repair.
Indeed, Endurance spent the first 11 days of its three-week stint at sea debugging its drill, which the team had never operated underwater before. But with a vessel chartered and a locked-in deployment date, the company couldn’t afford to wait for everything to work out perfectly. “We were still working on that generator hours before it got on the seafloor,” Redd told me. He’s used to that sort of thing, though, comparing it to making final tweaks to rockets already sitting on the launchpad. “That’s kind of the name of the game,” he said.
The trial took place at Axial Seamount, an active underwater volcano and the only place in the world with a cluster of hydrothermal vents connected to shore by fiber optic cable, which allows the Endurance team to monitor and control its system in real time from Seattle. While this was the company’s fifth deep-sea mission, it was the team’s first attempt to actually drill their own well.
After lowering their drill about a mile below the surface, the team bored two holes and turned the second into a well about 2 inches wide, lining it with pipe and sealing it with cement. But after losing so much time to debugging, the team only managed to drill about 52 feet deep — far short of its original 200-foot target.
Water then flowed up the well at about 260 degrees Celsius (around 500 degrees Fahrenheit), but the narrow borehole proved too restrictive to deliver enough heat for the generator to operate. So the team pivoted, connecting the generator directly to a naturally flowing, hotter hydrothermal vent instead. The generator then ran for a total of 29 seconds, producing about 2 kilowatts of net power for 8.7 seconds. That represents the total electricity the turbine generated, minus the 7 to 8 kilowatts needed to run its supporting components, such as the refrigerant pump and other onboard equipment.
Then a software glitch triggered the onboard battery safety system, which shut down the plant. When the team tried to restart the system, the power cable feeding the refrigerant pump failed, leaving the pump unable to restart. That was the end of the road. The mission wrapped up after three weeks at sea, a far shorter run than the team had hoped.
“The success criteria would be if we had left with the generator still on the seafloor; that would have been an example of sustained net power, and we didn’t get there,” Redd told me. Instead, the team brought the system back to Endurance’s Seattle headquarters, where it’s fixing the software as well as refurbishing and upgrading the hardware — which includes changing how it builds and tests subsea cables — to prepare for another mission sometime this winter. This time, the goal will be to generate sustained power from a much deeper well.
The team will need to demonstrate progress soon to keep its next major milestone on track: a planned 2-megawatt deployment off the coast of Tonga by the end of 2027. The project aims to supply electricity directly to the Tongan grid, which today is heavily dependent on expensive, imported diesel. Redd expects subsea geothermal to be cost-competitive with that fuel in this first pilot.
Getting there, however, is a formidable engineering challenge. While it’s long been a subject of academic curiosity, no one prior to Endurance had ever drilled an offshore geothermal well before, meaning the team can’t simply transplant existing land-based technology to the seafloor. “Every component that you would use terrestrially now needs to be either modified or built completely from scratch,” Redd explained. “And so you multiply that across every component required to make these kinds of infrastructure projects happen, and it’s a lot of work.”
No kidding. But if Endurance can pull it off, Redd sees this resource as “the perfect energy source for the future.” A conference paper presented by the geoscience company Viridien last year estimates that offshore geothermal resources worldwide could yield about 6 terawatts of recoverable electric power — nearly twice the world’s current continuous electricity output.
“We can access terawatts of power. There’s no fuel. We can site next to extremely large cities around the Pacific. We have no surface presence,” Redd said, ticking off the advantages. Plus, the three necessary ingredients for a high-quality geothermal well — permeable rock, high heat, and water — are widely accessible offshore, he added. Eventually, he expects subsea geothermal to undercut natural gas in Endurance’s target markets: electricity grids, industrial facilities, and data centers across the Pacific Islands, the U.S. West Coast, and Northeast Asia, all of which sit along the undersea volcanic zone known as the “Ring of Fire.”
The way Redd sees it, advances in subsea technology pioneered by the offshore wind, oil, and gas industries have cleared much of the technological path to making underwater geothermal a viable clean energy resource. In his view, what’s been missing is simply the ambition to chase the opportunity in the private market. SpaceX, he said, really proved what’s possible for a scrappy startup to achieve.
“It is quite new at industrial scale for a small company with a bunch of fairly young people to go after something like this,” he told me. “Before SpaceX went to launch a rocket as a private company, no one thought you could get to orbit as a private company. And so that has really seeded this ambition.”
On Greenland’s deepsea mining ban, Indonesia floating nuclear, and a solar boom
Current conditions: Hurricane Trudy has weakened from its peak as a Category 2 storm but still threatens up to 8 inches of rain as it swirls off Baja California • A nor’easter is howling through the Mid-Atlantic this week, hammering the coast with winds of up to 70 miles per hour • A humid overcast has settled over Paris this week as French authorities struggle to regain control after protests over living costs gave way to anarchic riots.
At least 47 major data center projects have been delayed, withdrawn, or blocked so far this year, according to data the regulatory intelligence service RegLayer shared with the Financial Times — and that may be a “conservative estimate.” Just 35% of planned data centers are “credible,” analysts told the newspaper, as more than 1,000 communities across the United States now have restrictions on artificial intelligence infrastructure. The data comes as investors look increasingly jittery about AI following ChatGPT-maker OpenAI’s missing a key revenue metric this year.
Those findings stand in contrast with the numbers from our data service, Heatmap Pro. Based on our research, at least 107 projects faced cancellation so far this year, putting 2026 on track to beat last year, which saw 108 proposals nixed.
Unless you’re living off the grid and away from any social media (if so, I’m jealous), then you can probably surmise that not-in-my-backyard opposition prevails in many such cases against proposed data centers. That makes selling would-be neighbors on the projects critical. New polling by the advocacy group GoodPower found that a binding promise to protect local electricity rates boosts support for the projects upward by as much as 14 points. Such a pledge worked primarily on the 78% of voters who distrust data centers. Another potential winner: Pair a data center with renewables. At least 46% of respondents to the poll said their support would increase if a project were powered by renewables. The survey spoke to 2,610 registered voters last month and oversampled in states with at least 200 data centers completed: Arizona, Georgia, Indiana, Pennsylvania, Texas, and Virginia.
Greenland wants to find ways to exploit its mineral riches in hopes of generating enough income from industries other than fishing and tourism to eventually wean off subsidies from the governments of Denmark and the European Union. Earlier this month, as you may recall, the self-governing Danish island gave a project the green light. But the government in Nuuk doesn’t want miners harvesting metals from the seabed surrounding the Arctic island, which are fertile fishing grounds and could, in theory, lead to mineral production without meaningful infrastructure to create jobs for Greenlandic people. Last week, the Greenlandic Parliament adopted a resolution requiring the government to draft legislation banning deep-sea mining. All members present voted to approve the proposal, according to Sermitsiaq, a leading newspaper in Nuuk. The ban would, if adopted, last until the end of 2029, with the possibility of an extension for two years at a time.

Long before the race for small modular reactors kicked off, Russia launched a floating nuclear power station and sailed the vessel up to the Arctic to power a small town. Now, as you may recall, the state-owned Russian nuclear company Rosatom is making plans to build more floating nuclear plants, and it has a major nuclear newcomer nation as an offtaker. Last week, NucNet reported, Rosatom announced a deal with Indonesia’s state-owned PT Pembangkit Listrik Nuklir to supply electricity to northern Indonesia from at least two floating nuclear plants with a capacity of 200 megawatts each.

Over the past decade, small-scale and rooftop solar systems increased from 18,812 gigawatt-hours to 92,979 gigawatt-hours, an increase of over 394%. That’s according to a new analysis from the Energy Information Administration, which found that California, Arizona, Texas, Florida are the regions with the most abundant solar resources. Even though the state has worse solar resources in general, New York ranked fifth as a result of growing capacity. Still, the rate of growth in generation has slowed over the past three years. l
The Trump administration is pulling out all the stops for Alaskans who want to drill and transport fossil fuels, mine minerals, and log trees. Now he’s easing rules on hunters. A new final rule from the National Park Service has revived a hunting method the Biden administration banned in 2024: Baiting bears with doughnuts soaked in bacon grease. Hunters use the baits to lure bears to close range before shooting them. “Some hunters prefer to use strong-smelling, high-calorie foods like pastries, doughnuts, meat scraps or fish remains to lure bears from miles away,” The New York Times reported. “But some conservationists say the practice is unethical and risks making the bears accustomed to human food, which could endanger people.”
