The House passed its version of the budget bill early Thursday morning, with even deeper cuts to clean energy added overnight.
Trump’s tax bill passed the House early Thursday morning, after a marathon session in the Rules Committee that began early Wednesday morning and stretched late into the night. The final floor vote came down to the slimmest of margins, 215 yeas to 214 nays, with House Freedom Caucus Chair Andy Harris voting “present.”
The clean energy tax credits, already on life support, barely made it out alive.
The text that now heads to the Senate retains many of the provisions that came out of the Ways and Means Committee last week, but would terminate some of the tax credits even more rapidly to appease Republican hardliners.
It still eliminates the electric vehicle tax credits after this year, except for vehicles produced by automakers that have sold fewer than 200,000 tax credit-qualified cars, which will be eligible for one additional year. It still terminates tax credits for residential energy efficiency, rooftop solar, and new, energy-efficient homes. And it still ends the clean hydrogen tax credit at the end of this year.
But for the clean electricity subsidies, the revised text nixes the previously proposed three-year phase-down schedule and bluntly cuts off any project that doesn’t break ground within 60 days of the bill’s passage — basically the same deal handed to the hydrogen industry.
The only concession to the many objections to the bill from the clean energy industry appears to be some carve outs for nuclear plants.
Here’s a rundown of everything that changed.
The revised text demands that clean power projects start construction within 60 days of the bill’s final passage in order to qualify for the production and investment tax credits, 45Y and 48E. Projects that are able to hit that deadline would also have to meet a second one — they would have to start operating before 2029.
But there’s an exception for advanced nuclear facilities, which would only have to start construction by 2029 to be eligible for the credits and would have no deadline to begin sending power to the grid.
The amended text also speeds up material sourcing requirements that prohibit clean power projects from using anything made in China. Under the earlier iteration, power companies would have had a full year to reorganize their supply chains — a timeline that industry experts already said was unworkable. The revised bill imposes the restriction starting January 1 of next year.
In summary, if you are developing a wind farm and want to qualify for tax credits, you now face an almost impossibly short eligibility timeline. You would have to start construction within two months of the reconciliation package passing, eliminate Chinese goods from your supply chain before the end of the year, and then get your project hooked up to the grid and operating by the end of 2028.
When that 60-day clock starts will depend on how long it takes the Senate to pass its version of the reconciliation bill and both houses to approve the final text, which could take weeks or months. Regardless, these new time restrictions would likely “TANK real projects in active development right now, killing jobs and costing investment,” as industry group Advanced Energy United’s managing director Harry Godfrey posted on social media Wednesday night. Godfrey went on to name six projects in Republican districts, including solar farms, solar on schools, and a long-duration storage installation, that would be affected.
To the few clean energy developers that can hit all of these deadlines, House Republicans have offered a small reward. The revised bill appears to retain transferability, the ability for developers to sell their clean energy tax credits to other companies and thereby access more capital more quickly and easily than they otherwise would. There is some confusion among energy experts, however, about exactly how this provision would apply, with Politico Pro reporting Thursday morning that only nuclear would be able to use it. Regardless, the 60-day deadline to start construction makes this mostly moot.
A new section of text takes aim at companies like Sunrun that lease solar installations to homeowners and businesses. Under current law, Sunrun typically claims the commercial investment tax credit (48E) for solar installations on customers' roofs. But the change would prohibit any company that leases solar or wind installations to a third party from claiming the tax credits for those projects.
Under the Way and Means version of the budget bill, the tax credit for electricity produced by existing nuclear plants would have phased down over three years before terminating in 2032. The revised bill nixes the phase-out, keeping the full amount of the credit in place until 2032, which is just one year earlier than the phase-out timeline in the Inflation Reduction Act.
The revised bill also allows nuclear plant owners to take advantage of transferability for as long as the credit is in effect — a provision that nuclear industry advocates told me was essential to keeping existing plants online.
The text does not make any amendments to the Ways and Means bill’s changes to the carbon capture (45Q), clean fuels (45Z), and advanced manufacturing (45X) projects. These projects would still not be able to use transferability past 2027.
The clean fuels credit would still be extended for four years, through the end of 2031, and come with looser carbon accounting rules. The clean manufacturing credit would still be cut short by a year, with wind manufacturers losing their eligibility even earlier, in 2028.
These provisions are not yet law, and there are a number of Republican Senators who have subtly, though publicly disagreed with the approach the House has taken to paring back the tax credits. Regarding the short timeline the Ways and Means Committee had proposed for claiming the tax credits, Kevin Cramer of North Dakota told Politico, “we’ll have to change that.” Shelley Moore Capito of West Virginia said she expected the “blanket” repeal of the tax credits to change, noting “there has been job creation around these tax credits.” And four Republicans led by Alaska’s Lisa Murkowski also sent a letter to party leadership back in April arguing to maintain the tax credits.
The House appeared to have its clean energy holdouts too, however. But as my colleague Matthew Zeitlin wrote on Wednesday, “at no point have these members ever seriously threatened to vote against the bill” in support of the tax credits, and at the end of the day their concerns were mostly ignored.
The Senate is about to take a week-long recess, and won’t be back in session until June 2. How long until the one big, beautiful bill becomes law, nobody knows. But we’ll soon see how hard the energy transition’s defenders are actually willing to fight.

The foreign entities of concern rules in the One Big Beautiful Bill would place gigantic new burdens on developers.
Trump campaigned on cutting red tape for energy development. At the start of his second term, he signed an executive order titled, “Unleashing Prosperity Through Deregulation,” promising to kill 10 regulations for each new one he enacted.
The order deems federal regulations an “ever-expanding morass” that “imposes massive costs on the lives of millions of Americans, creates a substantial restraint on our economic growth and ability to build and innovate, and hampers our global competitiveness.” It goes on to say that these regulations “are often difficult for the average person or business to understand,” that they are so complicated that they ultimately increase the cost of compliance, as well as the risks of non-compliance.
Reading this now, the passage echoes the comments I’ve heard from industry groups and tax law experts describing the incredibly complex foreign entities of concern rules that Congress — with the full-throated backing of the Trump administration — is about to impose on clean energy projects and manufacturers. Under the One Big Beautiful Bill Act, wind and solar, as well as utility-scale energy storage, geothermal, nuclear, and all kinds of manufacturing projects will have to abide by restrictions on their Chinese material inputs and contractual or financial ties with Chinese entities in order to qualify for tax credits.
“Foreign entity of concern” is a U.S. government term referring to entities that are “owned by, controlled by, or subject to the jurisdiction or direction of” any of four countries — Russia, Iran, North Korea, and most importantly for clean energy technology, China.
Trump’s tax bill requires companies to meet increasingly strict limits on the amount of material from China they use in their projects and products. A battery factory starting production next year, for example, would have to ensure that 60% of the value of the materials that make up its products have no connection to China. By 2030, the threshold would rise to 85%. The bill lays out similar benchmarks and timelines for clean electricity projects, as well as other kinds of manufacturing.
But how companies should calculate these percentages is not self-evident. The bill also forbids companies from collecting the tax credits if they have business relationships with “specified foreign entities” or “foreign-influenced entities,” terms with complicated definitions that will likely require guidance from the Treasury for companies to be sure they pass the test.
Regulatory uncertainty could stifle development until further guidance is released, but how long that takes will depend on if and when the Trump administration prioritizes getting it done. The One Big Beautiful Bill Act contains a lot of other new tax-related provisions that were central to the Trump campaign, including a tax exemption for tips, which are likely much higher on the department’s to-do list.
Tax credit implementation was a top priority for the Biden administration, and even with much higher staffing levels than the department currently has, it took the Treasury 18 months to publish initial guidance on foreign entities of concern rules for the Inflation Reduction Act’s electric vehicle tax credit. “These things are so unbelievably complicated,” Rachel McCleery, a former senior advisor at the Treasury under Biden, told me.
McCleery questioned whether larger, publicly-owned companies would be able to proceed with major investments in things like battery manufacturing plants until that guidance is out. She gave the example of a company planning to pump out 100,000 batteries per year and claim the per-kilowatt-hour advanced manufacturing tax credit. “That’s going to look like a pretty big number in claims, so you have to be able to confidently and assuredly tell your shareholder, Yep, we’re good, we qualify, and that requires a certification” by a tax counsel, she said. To McCleery, there’s an open question as to whether any tax counsel “would even provide a tax opinion for publicly-traded companies to claim credits of this size without guidance.”
John Cornwell, the director of policy at the Good Energy Collective, which conducts research and advocacy for nuclear power, echoed McCleery’s concerns. “Without very clear guidelines from the Treasury and IRS, until those guidelines are in place, that is going to restrict financing and investment,” Cornwell told me.
Understanding what the law requires will be the first challenge. But following it will involve tracking down supply chain data that may not exist, finding alternative suppliers that may not be able to fill the demand, and establishing extensive documentation of the origins of components sourced through webs of suppliers, sub-suppliers, and materials processors.
The Good Energy Institute put out an issue brief this week describing the myriad hurdles nuclear developers will face in trying to adhere to the tax credit rules. Nuclear plants contain thousands of components, and documenting the origin of everything from “steam generators to smaller items like specialized fasteners, gaskets, and electronic components will introduce substantial and costly administrative burdens,” it says. Additionally the critical minerals used in nuclear projects “often pass through multiple processing stages across different countries before final assembly,” and there are no established industry standards for supply chain documentation.
Beyond the documentation headache, even just finding the materials could be an issue. China dominates the market for specialized nuclear-grade materials manufacturing and precision component fabrication, the report says, and alternative suppliers are likely to charge premiums. Establishing new supply chains will take years, but Trump’s bill will begin enforcing the sourcing rules in 2026. The rules will prove even more difficult for companies trying to build first-of-a-kind advanced nuclear projects, as those rely on more highly specialized supply chains dominated by China.
These challenges may be surmountable, but that will depend, again, on what the Treasury decides, and when. The Department’s guidance could limit the types of components companies have to account for and simplify the documentation process, or it could not. But while companies wait for certainty, they may also be racking up interest. “The longer there are delays, that can have a substantial risk of project success,” Cornwell said.
And companies don’t have forever. Each of the credits comes with a phase-out schedule. Wind manufacturers can only claim the credits until 2028. Other manufacturers have until 2030. Credits for clean power projects will start to phase down in 2034. “Given the fact that a lot of these credits start lapsing in the next few years, there’s a very good chance that, because guidance has not yet come out, you’re actually looking at a much smaller time frame than than what is listed in the bill,” Skip Estes, the government affairs director for Securing America’s Energy Future, or SAFE, told me.
Another issue SAFE has raised is that the way these rules are set up, the foreign sourcing requirements will get more expensive and difficult to comply with as the value of the tax credits goes down. “Our concern is that that’s going to encourage companies to forego the credit altogether and just continue buying from the lowest common denominator, which is typically a Chinese state-owned or -influenced monopoly,” Estes said.
McCleery had another prediction — the regulations will be so burdensome that companies will simply set up shop elsewhere. “I think every industry will certainly be rethinking their future U.S. investments, right? They’ll go overseas, they’ll go to Canada, which dumped a ton of carrots and sticks into industry after we passed the IRA,” she said.
“The irony is that Republicans have historically been the party of deregulation, creating business friendly environments. This is completely opposite, right?”
On the budget debate, MethaneSAT’s untimely demise, and Nvidia
Current conditions: The northwestern U.S. faces “above average significant wildfire potential” for July • A month’s worth of rain fell over just 12 hours in China’s Hubei province, forcing evacuations • The top floor of the Eiffel Tower is closed today due to extreme heat.
The Senate finally passed its version of Trump’s One Big Beautiful Bill Act Tuesday morning, sending the tax package back to the House in hopes of delivering it to Trump by the July 4 holiday. The excise tax on renewables that had been stuffed into the bill over the weekend was removed after Senator Lisa Murkowski of Alaska struck a deal with the Senate leadership designed to secure her vote. In her piece examining exactly what’s in the bill, Heatmap’s Emily Pontecorvo explains that even without the excise tax, the bill would “gum up the works for clean energy projects across the spectrum due to new phase-out schedules for tax credits and fast-approaching deadlines to meet complex foreign sourcing rules.” Debate on the legislation begins on the House floor today. House Speaker Mike Johnson has said he doesn’t like the legislation, and a handful of other Republicans have already signaled they won’t vote for it.
The Environmental Protection Agency this week sent the White House a proposal that is expected to severely weaken the federal government’s ability to rein in planet-warming pollution. Details of the proposal, titled “Greenhouse Gas Endangerment Finding and Motor Vehicle Reconsideration,” aren’t clear yet, but EPA Administrator Lee Zeldin has reportedly been urging the Trump administration to repeal the 2009 “endangerment finding,” which explicitly identified greenhouse gases as a public health threat and gave the EPA the authority to regulate them. Striking down that finding would “free EPA from the legal obligation to regulate climate pollution from most sources, including power plants, cars and trucks, and virtually any other source,” wrote Alex Guillén at Politico. The title of the proposal suggests it aims to roll back EPA tailpipe emissions standards, as well.

So long, MethaneSAT, we hardly knew ye. The Environmental Defense Fund said Tuesday that it had lost contact with its $88 million methane-detecting satellite, and that the spacecraft was “likely not recoverable.” The team is still trying to figure out exactly what happened. MethaneSAT launched into orbit last March and was collecting data about methane pollution from global fossil fuel infrastructure. “Thanks to MethaneSAT, we have gained critical insight about the distribution and volume of methane being released from oil and gas production areas,” EDF said. “We have also developed an unprecedented capability to interpret the measurements from space and translate them into volumes of methane released. This capacity will be valuable to other missions.“ The good news is that MethaneSAT was far from the only methane-tracking satellite in orbit.
Nvidia is backing a D.C.-based startup called Emerald AI that “enables AI data centers to flexibly adjust their power consumption from the electricity grid on demand.” Its goal is to make the grid more reliable while still meeting the growing energy demands of AI computing. The startup emerged from stealth this week with a $24.5 million seed round led by Radical Ventures and including funding from Nvidia. Emerald AI’s platform “acts as a smart mediator between the grid and a data center,” Nvidia explains. A field test of the software during a grid stress event in Phoenix, Arizona, demonstrated a 25% reduction in the energy consumption of AI workloads over three hours. “Renewable energy, which is intermittent and variable, is easier to add to a grid if that grid has lots of shock absorbers that can shift with changes in power supply,” said Ayse Coskun, Emerald AI’s chief scientist and a professor at Boston University. “Data centers can become some of those shock absorbers.”
In case you missed it: California Governor Gavin Newsom on Monday rolled back the state’s landmark Environmental Quality Act. The law, which had been in place since 1970, required environmental reviews for construction projects and had become a target for those looking to alleviate the state’s housing crisis. The change “means most urban developers will no longer have to study, predict, and mitigate the ways that new housing might affect local traffic, air pollution, flora and fauna, noise levels, groundwater quality, and objects of historic or archeological significance,” explainedCal Matters. On the other hand, it could also mean that much-needed housing projects get approved more quickly.
Tesla is expected to report its Q2 deliveries today, and analysts are projecting a year-over-year drop somewhere from 11% to 13%.
Jesse teaches Rob the basics of energy, power, and what it all has to do with the grid.
What is the difference between energy and power? How does the power grid work? And what’s the difference between a megawatt and a megawatt-hour?
On this week’s episode, we answer those questions and many, many more. This is the start of a new series: Shift Key Summer School. It’s a series of introductory “lecture conversations” meant to cover the basics of energy and the power grid for listeners of every experience level and background. In less than an hour, we try to get you up to speed on how to think about energy, power, horsepower, volts, amps, and what uses (approximately) 1 watt-hour, 1 kilowatt-hour, 1 megawatt-hour, and 1 gigawatt-hour.
Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

Here is an excerpt from our conversation:
Jesse Jenkins: Let’s start with the joule. The joule is the SI unit for both work and energy. And the basic definition of energy is the ability to do work — not work in a job, but like work in the physics sense, meaning we are moving or displacing an object around. So a joule is defined as 1 newton-meter, among other things. It has an electrical equivalent, too. A newton is a unit of force, and force is accelerating a mass, from basic physics, over some distance in this case. So 1 meter of distance.
So we can break that down further, right? And we can describe the newton as 1 kilogram accelerated at 1 meter per second, squared. And then the work part is over a distance of one meter. So that kind of gives us a sense of something you feel. A kilogram, right, that’s 2.2 pounds. I don’t know, it’s like … I’m trying to think of something in my life that weighs a kilogram. Rob, can you think of something? A couple pounds of food, I guess. A liter of water weighs a kilogram by definition, as well. So if you’ve got like a liter bottle of soda, there’s your kilogram.
Then I want to move it over a meter. So I have a distance I’m displacing it. And then the question is, how fast do I want to do that? How quickly do I want to accelerate that movement? And that’s the acceleration part. And so from there, you kind of get a physical sense of this. If something requires more energy, if I’m moving more mass around, or if I’m moving that mass over a longer distance — 1 meter versus 100 meters versus a kilometer, right? — or if I want to accelerate that mass faster over that distance, so zero to 60 in three seconds versus zero to 60 in 10 seconds in your car, that’s going to take more energy.
Robinson Meyer: I am looking up what weighs … Oh, here we go: A 13-inch MacBook Air weighs about, a little more than a kilogram.
Jenkins: So your laptop. If you want to throw your laptop over a meter, accelerating at a pace of 1 meter per second, squared …
Meyer: That’s about a joule.
Jenkins: … that’s about a joule.
