And that’s on top of the constitutional questions.

One of the biggest stories of the new Trump administration is the president’s attempt to block congressionally mandated spending. So far, most of the discussion over this freeze has focused on whether it violates federal law and the Constitution. But another front is likely to open soon in that legal battle — and it has received much less attention.
On his first day in office, Trump froze all federal spending tied to the Inflation Reduction Act and the $1 trillion infrastructure law passed during Joe Biden’s presidency. Although Trump has since relented on other spending freezes — such as a short-lived block on virtually all federal payments — he has continued to withhold these energy, climate, and infrastructure funds, even after a federal judge ordered their release on Monday.
Continuing this freeze for longer than 45 days would take an act of Congress, and it’s unclear whether the Trump administration intends to get one. It seems to be gearing up to fight a Supreme Court battle over whether the president has an inherent “impoundment” authority to block federal funding unilaterally (more on that later).
That constitutional fight will obviously be extremely important. But as hundreds of CEOs and local government officials are now surely realizing, this battle is not the only legal front on which the Trump administration’s spending freeze will be fought.
That is because — as long as the freeze continues — the Trump administration is going to start violating hundreds or even thousands of contracts and legally binding spending agreements. The Trump spending fight is not only about policy and the Constitution, in other words, but also about contract law.
The companies and local governments that are now being strung along by the Trump administration did not make a vague handshake agreement with the Biden administration. Instead, they signed a contract with the federal government to receive a certain amount of money in exchange for doing a certain activity. The administration might have changed since then. But the government is still bound by its debts and obligations.
Those companies have now spent money — in some cases more than tens of millions of dollars — to fulfill their side of the contract. They have bought equipment, purchased land, and hired workers. Those companies’ contracts with the federal government are as legally binding as any other contract between two parties — and the courts are as empowered to defend those contracts as they are any others.
There is a significant amount of money tied up in these agreements. By the end of 2024, the Biden administration had “obligated” more than $96 billion of grants from the Inflation Reduction Act, while the Department of Energy’s loans office had “finalized” more than $60 billion in lending. Both terms generally mean that a contract has been signed.
As Heatmap has written before, just because the government has signed a contract for a certain amount of money doesn’t mean that the money has gone out the door. Many federal contracts are designed, basically, as ongoing invoicing relationships: A private party agrees to do something for the government, the private party does it, and then the private party brings back its receipts and asks the government for reimbursements.
The government has been refusing to make those private parties whole, even though those private parties have kept up their side of their agreements. (Note that at no point, ever, has the Trump administration claimed on the record that the private entities it’s now refusing to pay are in breach of contract. It is simply saying that it would rather not pay them just yet for political reasons.)
This has several important consequences for what is about to happen next.
The first is that the Trump administration is about to face dozens and perhaps hundreds of lawsuits over breach of contract. The president cannot simply announce that the contracts are void, like Michael Scott declaring bankruptcy in The Office. If the president or his officials want to cut off funding to IRA and infrastructure law grant and loan recipients, then they will need to give specific reasons under the contract for terminating and then defend those claims in court — provided that the recipient sues. Under a law called the Tucker Act, companies can sue the federal government for breaching a contract in the Court of Federal Claims, a special court in Washington, D.C. These lawsuits will not be about MAGA policies, but rather about the facts of each contract and whether the parties are in compliance with them.
At the same time, the Trump administration will likely be waging a fight over “impoundment.” Some officials in the Trump administration — including Russ Vought, the Project 2025 architect who now leads the White House budget office — profess that the president has an inherent authority that allows him to unilaterally block federal funding. This is despite the fact that the Constitution does not mention such a capacious authority, and the Supreme Court has historically rejected other presidential ploys, such as President Bill Clinton’s use of the line-item veto, to accept some parts of the federal budget and ignore others.
This will create, at least at first, a two-track legal fight over the Trump administration’s spending freeze. At the high level, President Trump will be fighting over the political and constitutional question of whether he can unilaterally block funding that has been appropriated by Congress. But at the lower level, federal agencies may be sparring with hundreds of companies about whether they can wriggle their way out of the contracts they have already signed. These dozens of potential smaller fights will command an enormous amount of time and personnel attention — not only from the companies, nonprofits, and local governments trying to secure what they are owed, but also from the Trump administration, which has finite resources.
These skirmishes will have economic consequences — and while these might be small in the context of America’s $29 trillion economy, they will gradually deepen. By refusing to honor its contracts, the Trump administration is forcing private companies to bear public costs. Those companies will delay hiring employees and investing in new equipment as they await repayment; some will furlough workers and go bankrupt. The burden will become more and more significant every day that the Trump administration continues its spending freeze.
These costs will not be randomly distributed through the economy, but rather concentrated primarily in sectors located in rural areas and affecting working-class Americans. Professional environmentalists in Seattle will continue to have a job regardless of what happens to some rural school district’s microgrid project. But the construction workers and electricians set to build that grid will lose income.
For this reason, the energy and infrastructure freeze does not strike me as a very wise move, politically — particularly as U.S. economic sentiment is worsening. One reason it is politically prudent for lawmakers, and not the president, to make spending decisions is that representatives understand their districts much better than federal officials in Washington, D.C.
This suggests the final takeaway: The Trump administration is beginning to play a very dangerous game with the United States. The American economy’s strength and prosperity arises from its territorial resource wealth, its educated and productive workforce, its secure defensive position, and — crucially — a set of financial intangibles that are ultimately backed up by federal contracts. The federal government is the largest counterparty in the global economy because it can be relied upon to pay its debts. If it begins to back out of contracts hither and thither, especially if primarily for partisan political reasons, then it will ultimately damage every American.
This is not a new or novel thought. Writing in 1790, Treasury Secretary Alexander Hamilton said that the “punctual performance of contracts” was the key to maintaining the United States’ good credit. “States, like individuals, who observe their engagements, are respected and trusted: while the reverse is the fate of those who pursue an opposite conduct,” he said. “Every breach of the public engagements, whether from choice or necessity, is in different degrees hurtful to public credit.”
It isn’t unusual for new administrations to pause some spending at the beginning of their terms, and perhaps the Trump administration will soon prove the worriers wrong and lift the spending freeze. But I fear it will not. It is very possible that in the next several months, the administration will begin to breach dozens of its public engagements. This will hurt the energy, automaking, and construction sectors in the near term. It will cause grief for the president — and, I worry, all of us — soon after.

“We will not cease exports of U.S. diesel,” the Secretary of Energy told us at Heatmap House.
Secretary of Energy Chris Wright threw cold water on a potential diesel export ban, telling Heatmap executive editor Robinson Meyer that the president “didn’t endorse it.”
“We are open to any ideas to lower energy prices for Americans,” Wright said at our Heatmap House event at New York Climate Week. “We have a continual, thoughtful dialog based on the facts on the ground of what are the most practical steps moving forward, and it looks like right now we do need to grow the diesel supply in the United States.”
There could be some adjustments to the diesel industry, Wright told Rob, saying there may “be some tweak in where diesel flows out of U.S. refineries.” About a full-scale ban, however, he was unequivocal. “We will not cease exports of U.S. diesel.”
That stands in contrast to President Trump’s remarks Tuesday, when he told reporters, “I’ve said, ‘Let’s not send out the diesel.’ I’ve called for it. I’ve called for it within my people.” Politico reported Wednesday afternoon that the administration is “preparing” a 90-day export ban.
When asked if a diesel export ban would hurt America’s reputation as an energy superpower, Wright told Heatmap, “It certainly would have impacts.” But, he added, “I don’t think there’s serious consideration, although there’s always been a dialogue. I don’t think you will see a blanket ban on diesel. And yes, of course, we want to be the energy superpower supplying the whole world.”
Some Republicans in Congress have called for a diesel export ban, including Iowa Senator Chuck Grassley, who represents agriculture-heavy Iowa. High diesel prices impose a particularly large cost on two groups: farmers and New Englanders. Farmers need diesel to fuel equipment to harvest crops and trucks to move their goods, while millions of New Englanders rely on heating oil — which is virtually interchangeable with diesel — to heat their homes in the winter. Bills for heating oil may exceed $2,000 this winter, according to Mark Wolfe, the executive director of the National Energy Assistance Directors Association
Diesel prices today are sitting at just over $6.50 per gallon, according to AAA, up from $3.69 a year ago and $5.60 just a month ago.
The former vice president joined us at Heatmap House at New York Climate Week to talk about electric vehicles, artificial intelligence, and why clean energy will ultimately win.
In front of a packed room at Heatmap House on Wednesday morning, former Vice President Al Gore made the case for optimism on climate change.
“There is a possibility we will look back on this year of 2026 as the positive tipping point on climate,” he said.
He started with some high water marks in renewable energy and electric vehicles. Last year was the first year that the production of energy from renewable sources exceeded the overall increase in global energy demand, for example. Whereas 20 years ago, when Gore’s landmark climate change film An Inconvenient Truth premiered, there were virtually no electric vehicles on the road, by the end of this year about 30% of all new cars sold globally will be EVs.
On top of that, he later added, “the war in Iran marks the second time in four years that the fossil fuel supply chain has been disrupted, and price volatility has returned, and people around the world have reacted to this and in a really dramatic way.” Just in the past six months, EV sales reached record levels in 50 countries; Korea’s president committed to speed its transition off fossil fuels; Thailand announced a shift from liquified natural gas to renewables; and solar is booming in Africa.
“These are signs that this thing is really moving into high gear,” he said. “The fossil fuel industry is losing, they know they’re losing, and they’re trying to slow down how quickly they lose.”
Gore was also surprisingly hopeful about artificial intelligence, arguing that data centers were a cause for concern but “not a justification for panic.” He’s not convinced that the carbon emissions from powering artificial intelligence will have a decisive impact on our climate trajectory, and is far more worried about “cognitive atrophy and the emergence of an intelligence that makes us no longer the apex intelligence on the planet.”
The conversation with Gore followed an interview with one of his climate champion descendents, so to speak. Mikie Sherrill, the governor of New Jersey, showed off her energy bona fides in a conversation about her approach to affordability and data centers. She talked up her administration’s swift approvals of solar and battery projects to ensure they made the deadline for federal tax credits, lifting the state’s moratorium on nuclear, and implementation of virtual power plants.
“There is a crisis going on, so you cannot simply say to people, ‘Sorry, your bills are just going to keep skyrocketing,’” she said. “That is not the answer, which is why we’ve acted so aggressively.”
Sherrill also criticized data center developers for the way they have frequently come into the state without engaging with communities. “I told a data center, I said, ‘You guys have been horrible at it. I’m just telling you, nobody knows what a data center is, and you need to explain why it's even important. Are you curing cancer? What are you doing? Why is this a societal benefit?’”
She encouraged future Democratic candidates for public office to make sure they have a deep understanding of the specific energy circumstances of their state, and to speak to that on the campaign trail. “The can has been kicked down the road on too many different issues, and if you were going to try to duck your head and say some mealy-mouthed thing like, ‘We’re going to do all of the above’ and ‘Everyone's welcome and we like business,’ that’s not going to cut it.”
On offshore wind lawsuits, transmission woes, and a nuclear IPO
Current conditions: A potential nor’easter is barreling toward New York City, potentially hitting the five boroughs just as world leaders gathered for the United Nations General Assembly get set to fly home • Hurricane Polo has rapidly strengthened into a Category 5 storm off Mexico’s Pacific coast, threatening flooding, winds, and storm surge • Yet another tropical storm is forming off the coast of Hawaii, risking mudslides and flooding.
The air is crisp here in Manhattan. UN representatives are grandstanding. And many of the biggest names in energy and climate are gathering alongside my colleagues at Heatmap House, our day-long summit for New York Climate Week. Some of the talks today include:

In his opening address to the annual gathering of nearly all the world’s nations in New York, United Nations Secretary General António Guterres called for an end to what he desscribed as “the most profound intergenerational power imbalance of all.” Climate change, he said, has led to “one group profiting, while those least responsible suffer first and worst.” The former Portuguese prime minister from the Iberian country’s leading center-left party highlighted last month’s catastrophic flood in Nepal as an example of the unfair toll global warming is taking. “As tragic events have shown, impacts are arriving sooner, hitting harder, and spreading further than many anticipated. Now we face a near certain breach of the 1.5-degree limit, with a supersized El Niño speeding straight for humanity,” he said. “The dangers are real. But so is the hope.”
President Donald Trump struck a decidedly different tone in his remarks to the assembly. In a characteristically fiery speech defending the U.S. war with Iran, he vowed to “annihilate the Islamic Republic “ or “drive them into hell with no chance of survival” if Tehran doesn’t agree to a peace deal with Washington soon — and that doing so would bring down oil prices. “If we stand united, we will soon see a world free of the last 51-year menace of Iranian terror,” Trump said. “And oil prices will come plummeting down even lower than they were at the start of the conflict. And they were very low in the United States. They were really low. With courage and resolve, anything is possible.” As an example, he pointed to what he called the largest oil deal in history with Venezuela last month. “When you add the United States and Venezuela together, we have more than 60% of the oil in the world,” Trump said. “So it’s perhaps the biggest deal. It was a war, but it’s perhaps the biggest deal ever made. To the victor belong the spoils.” Among the other spoils the president sees: Tuesday’s signing of his updated deal with Greenland to permanently bar Russian, Chinese, and other adversaries from making large-scale investments or setting up military outposts on the Danish-controlled Arctic island.
Back in June, New York Attorney General Letitia James filed what my colleague Emily Pontecorvo clocked as the first major state lawsuit challenging any of the Trump administration’s series of deals to pay offshore wind developers to abandon their projects. The lawsuit zeroed in on TotalEnergies and the $1 billion the Department of the Interior offered for the French giant to walk away from two proposed projects. On Tuesday, Albany announced two more lawsuits seeking to block deals with the developers Bluepoint Wind and Invenergy that, combined, would equal “$1.4 billion in taxpayer dollars in exchange for canceling four critical offshore wind projects.” New York Governor Kathy Hochul, who joined the lawsuit, admonished “the Trump administration’s unlawful pay-to-not-play scheme to pressure companies to forgo planned offshore wind projects in America,” which she called “an outrageous abuse of taxpayer dollars that hurts our ability to meet our energy needs.”
That same day, California Attorney General Rob Bonta filed a lawsuit over the Interior Department’s deal with Invenergy to kill off what would have been one of the first major offshore wind projects on the West Coast. “At a time when we need more reliable, clean energy, President Trump is trying to send $111 million dollars to his fossil fuel industry friends and wants taxpayers and working families to cover the tab,” Bonta said in a press release. “This outrageous abuse of taxpayer dollars will damage the offshore wind industry and create unnecessary obstacles to clean and reliable energy powering our homes and economies.” Both states explicitly tied the timing of the lawsuits to New York Climate Week, the five-day series of events around Manhattan that are tied to the UN General Assembly and seen as the aperitif for November’s global climate talks in Turkey.

A 190-mile transmission line stretching across Wisconsin is drawing blowback from Democrats and Republicans. The state’s congressional delegation is increasingly aligned. Representative Mark Pocan, a Democrat, said Midcontinent Grid Solutions’ outreach to residents on the power line “does not match the scale of the project’s impact on their land, their livelihoods, and their communities,” the Milwaukee Journal Sentinel reported. Senator Tammy Baldwin, another Democrat, called for a “slowdown” of the development process. On the other side of the aisle, Republican Representative Derrick Van Orden has backed a full moratorium on the project.
Coincidentally, Trump has signaled he’s willing to ease the administration’s blockade on renewables in a bid to secure a federal permitting deal with Democrats, Politico reported Tuesday. Two unnamed sources told the outlet that Trump has agreed to direct the Department of Defense to start clearing its queue of long-delayed onshore wind projects. My colleague Jael Holzman reported last week that, despite a court ruling ordering the military to resume its reviews, the administration hasn’t yet.
It was a bullish time for nuclear, it was a bearish time for nuclear. Billions of dollars are flowing into projects and ideas for reactors are proliferating as has not been seen since the mid-20th century atomic power buildout in North America, Europe, and East Asia. But startups debuting on the stock market are falling far short of expectations. Fuel maker Standard Nuclear went public in July in what Bloomberg called “a downsized U.S. IPO,” while the Amazon-backed next-generation reactor company X-Energy has fallen nearly 40% below its IPO price. America’s nuclear champion, Westinghouse, is still eyeing a $50 billion valuation ahead of a potential IPO. But it remains unclear whether that deal will ultimately go through. The market uncertainty isn’t stopping one of Europe’s most advanced nuclear startups from going public in the U.S. On Tuesday, Newcleo listed on the Nasdaq after completing a $247 million deal with a special purpose acquisition company, or SPAC, essentially a cheat code for a swift IPO that involves merging with an already-traded black-check company and thus allowing the firm to avoid the months of due diligence with investment bankers that typically precedes a stock market debut. Newcleo CEO Stefano Buono called the deal “a new steppingstone that sets up” the company “for long-term success.”
For fusion no longer to be “the energy source of tomorrow that always will be,” as the old joke goes, the startups promising to bring about the so-called holy grail of clean power need to scale up supply chains. Inertia, the fusion startup that formed with much of the team of U.S. government scientists that pulled off the historic 2022 breakthrough that made fusion energy a possibility, is now laying the groundwork for commercialization. On Tuesday, the company, led by former Twilio CEO Jeff Lawson (yes, the same one that’ll be at Heatmap House), announced what it called “close collaborations” with three companies to begin manufacturing the lasers needed for Inertia’s fusion power plants at scale. “These are the first of many industrial collaborations we will coordinate to bring the scale of mass manufacturing to industrialize the laser fusion energy supply chain,” the company said.
