Here’s why Trump’s funding freeze created so much chaos.

A memo issued to federal agencies from the White House budget office on Monday landed like an atom bomb. The Trump administration ordered a pause on the obligation or disbursement of federal financial assistance. In laymen’s terms, that means an immediate freeze on payouts of federal grants — even those already awarded. The news sent a mushroom cloud of confusion and fear through state and local governments, schools, nonprofits, and companies that have set up programs and financed projects based on that funding.
Experts say the move is illegal and many groups moved quickly to sue. By Tuesday afternoon, a federal judge had temporarily blocked the funding freeze.
A 1974 law called the Impoundment Control Act prohibits the president from holding back congressionally appropriated funds indefinitely without permission from Congress. As Georgetown University law professor David Super explained in a blog post today, the law also prohibits presidents from deferring funds based on policy disagreements. The memo from the Office of Management and Budget makes Trump’s policy intent explicit — it specifically directs agency heads to pause activities that “may be implicated by the executive orders, including, but not limited to … DEI, woke gender ideology, and the green new deal.” It notes that the pause “will provide the Administration time to review agency programs and determine the best uses of the funding for those programs consistent with the law and the President’s priorities.”
Some have interpreted the memo as the first salvo in an attack on the separation of powers. But perhaps the most immediate reason the pause is so cataclysmic is because of the way federal grants work.
When an entity wins federal funds, be it $270 million to expand a copper recycling facility in Kentucky, or $1.2 billion to build a hydrogen hub on the Gulf Coast, or $149 million for the state of Wisconsin to set up home energy efficiency rebate programs, the awardee doesn’t just get the money transferred over to their bank account in a lump sum. Every federal grant program works slightly differently, but the majority of them are essentially pay-as-you-go.
The first thing that happens after an agency awards a grant to a given project is the two parties negotiate a contract, outlining the terms under which the award will be administered. What milestones does the project need to hit? What does the recipient need to report back to the agency? In the context of many Department of Energy programs, this contract is called a cooperative agreement, where federal staff continue to be involved in the project throughout its implementation.
After both parties sign the agreement, the money is considered “obligated,” which means the government has a legal duty to disburse those funds per the terms of the agreement. There might be some initial transfer of funds at this point to kickstart the project, depending on the program and contract. But the recipient may not get any money at all until they submit for reimbursement.
Yep, that’s right. If you win millions of dollars from the government, you still need to submit your receipts to get paid.
This is typically not a one-and-done process. A lot of grant programs fund years-long projects, and recipients regularly invoice the government for reimbursement throughout that time. In the case of the DOE, most programs also have a cost-share requirement, where the agency will reimburse a project developer for whatever portion of the expenses it has agreed to pay. For the Inflation Reduction Act’s Home Energy Rebates, where the funding is distributed to states to implement their own programs, the program is set up to transfer funds to state energy offices in four “tranches” as recipients hit certain benchmarks.
While some projects are fully obligated up front, meaning the grantee is entitled to the full amount, others are obligated in phases. For example, the Department of Energy has selected seven regional hydrogen hubs to receive up to $7 billion. But each of those seven hubs has only been awarded a portion of the funding for “phase 1,” which can be used to pay for “initial planning, design, and community and labor engagement activities.” When they are ready to move into phase 2, they’ll have to negotiate a new award for project development, permitting, and financing. Each advancement is subject to a go/no-go decision by the DOE.
Before Biden left office, his administration said it had obligated 85% of all grants from the Inflation Reduction Act. But as you can see, most of that money is not yet out the door.

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.”
