Let’s play out what could happen as the House Ways and Means Committee does its work.

One of the most important fights over the Inflation Reduction Act’s survival has finally arrived. But it’s not playing out in the open. It’s happening behind the closed doors of a powerful House committee in charge of tax policy.
The House Ways and Means Committee is writing its version of Republicans’ budget reconciliation bill, the centerpiece of President Donald Trump’s legislative agenda. The committee could release that text as soon as mid-May. And other than a few broad outlines — the text will extend Trump’s tax cuts for the wealthy, and it will increase the deficit by no more than $2.8 trillion — nobody has any idea what it will say.
Whatever the final text, though, will give us the first real sense of how likely the Inflation Reduction Act’s tax credits are to survive in the Trump tax bill. After months of speculation and tea leaf-reading, the House Ways and Means Committee’s draft will represent an opening position of sorts for Republican leadership — and illustrate just how close to repeal the majority is willing to get.
The committee could take a scorched-earth approach, cutting essentially every IRA tax credit in order to force members to fight to get policies back into the final bill. Or it could reform some tax credits so significantly that it effectively repeals the IRA, even if many policies remain on the books.
It could also reform some credits — such as the electric vehicle and clean electricity tax credits — while leaving most others untouched.
The most important suggestion of what will be in the final version came on Thursday in a new letter addressed to Jason Smith, the Ways and Means Committee chairman, and signed by 38 House Republicans. The letter demands the IRA’s full repeal — essentially heralding a potential new “anti-IRA” caucus within the GOP.
“We are deeply concerned that President Trump’s commitment to restoring American energy dominance and ending what he calls the ’‘green new scam’ is being undermined by parochial interests and short-sighted political calculations,” the letter says.
The letter writers focus their ire on subsidies for “wind and biofuel[s] … carbon capture and hydrogen … [and] solar and electric vehicles” that they say form the backbone of the bill.
So far, House Republicans have largely written letters about the IRA to call for its preservation. Last summer, 18 House Republicans wrote to Speaker of the House Mike Johnson to ask him to move gingerly around any “repeal or reform” of the tax credits should Republicans win the November election.
“We must reverse the policies which refine American families while protecting and refining those that are making our country more energy independent and America more energy secure,” the letter said.
Since then, the number of pro-IRA voices in the GOP has risen. Last month, 21 House Republicans wrote to Johnson again in support of the law. But their language was slightly changed, advising that any reforms proceed in a “targeted and pragmatic fashion.” They did, however, oppose “premature credit phase outs” or restrictions on transferability.
Speaking earlier this week at a Semafor event, the Illinois Republican and Ways and Means member Darin LaHood imagined phasing out some of the energy tax credits earlier.
“The approach we’'re looking at now is how you have an appropriate ramp-down [of IRA tax credits] that allows for businesses and companies to continue to be active in this space, but also saves money," LaHood said.
He added that there is a “bullseye” on the clean energy law, and said that “we’ll see” whether any of its provisions are preserved.
Whatever form the final law takes, this legislative vehicle will likely determine the fate of the IRA’s energy tax credits and other climate spending. Trump has lambasted the IRA, and some Republicans believe that its tax credits should be repealed to pay for their tax cuts for wealthy earners.
Ways and Means will not automatically control the final product. Ultimately, they will have to reconcile their version of the text with what’s written by their counterpart, the Senate Finance Committee. Other committees will oversee the IRA’s environmental grants and loans. (My colleague Emily Pontecorvo wrote about the first markup — from the House Transportation and Infrastructure Committee — on Tuesday.) But the Senate has a more forgiving budget target than the House does, which means the Ways and Means Committee is where the IRA could go to die. That’s because it oversees tax policy — and therefore manages the IRA’s all-important tax credits.
The committee also has a spending problem. The legislative process Republicans have chosen to pass their budget bill, known as reconciliation, begins with establishing binding spending limits for committees in both the House and the Senate. That process wrapped up last month.
Under the guidelines passed by the House earlier this year, the Ways and Means Committee can expand the deficit by as much as $4.5 trillion. But simply extending the 2017 tax cuts’ expiring provisions will cost $4.4 trillion — and the committee wants to do more besides, including expanding the deductions that people can claim for their local and state taxes. The committee will struggle to pay for everything it wants to do — and it could look to repealing parts of the IRA to fix it.
It doesn’t help that Representative Jason Smith of Missouri, the Ways and Means chairman, has called the IRA “welfare for the wealthy and well-connected.”
The committee’s conservative bent — and the fact that GOP lawmakers broadly want to stay on track to pass a bill by the end of the summer — mean that the IRA tax cuts are especially vulnerable during this period.
Most of the IRA’s tax credits are due to sunset in 2032. But one measure — a technology-neutral credit to support new clean electricity generation — could run for much longer than that.
Under the law as it stands today, that credit is supposed to last until the United States eliminates much of the greenhouse gas emissions produced by its power grid as compared to 2022 levels. Even if the credit remains in place, that could take another 30 or 40 years to happen, by one estimate — making the tech-neutral tax credit one of the most important climate policies in the law. The IRA’s power sector policies are responsible for more than 80% of the law’s emissions-reducing impact.
That also makes it among the most expensive policies in the law. When Republicans talk about ending tax credits early, the tech-neutral tax credit is an obvious target. Two lawmakers from North Dakota — Representative Julie Fedorchak and Senator Kevin Cramer — are working on language to phase out some tax credits in five years, Axios Pro has reported.
That would shut down the credit by 2030. But ending the credit by then could reshape what kind of energy technologies the law supports. Republicans tend not to see all zero-carbon electricity equally — while they often champion nuclear and advanced geothermal generation, many look less favorably on wind and solar power.
But by terminating the tech-neutral tax credit at the end of the decade, Republicans could help essentially the very technologies they don’t want. There are no new nuclear or geothermal projects in the development pipeline across the country, and new ones are unlikely to crop up until the late 2020s at the earliest. Under the law, energy projects must be “placed in service” by the time a tax credit expires, meaning that virtually no new nuclear or geothermal projects could qualify.
New nuclear projects will face especially serious trouble if the Trump administration guts the Department of Energy’s in-house bank, the Loan Programs Office, as now seems likely.
At the same time, there are plenty of new solar and battery projects planned across the country. Developers of these projects could rush to get them into service before a potential 2029 sunset date. The industry even has experience hurrying projects to completion: It often had to do so during the 2010s, when the solar investment tax credit faced repeated expirations.
Other Republicans have suggested terminating the law’s transferability clause. Under the IRA as it stands today, companies can sell their tax credits to other firms that can better use the subsidy. Depending on how it’s implemented, that reform could hurt the IRA by reducing the value of its tax credits, because companies will have to adopt more complicated financial structures in order to claim a given subsidy. Historically, solar and wind developers have more experience adopting these arcane structures than the nuclear or geothermal industries, which have fewer projects under their belt.
Speaking at a Heatmap event on Thursday, Republican Senator John Curtis of Utah said he was still hopeful that the IRA would survive without significant cuts.
“I don’t think that makes it through the House,” he said when asked if the Ways and Means Committee could slash the IRA tax credits outright. “There’s a lot of insecurities in the Republican Party about not cutting and about where the boundaries are.”
We’ll have a much better sense of where those boundaries are soon.
Editor’s note: Updates to reflect Ways and Means delaying its markup.

New guidelines for the clean fuel tax credit reward sustainable agriculture practices — but could lead to greater emissions anyway.
The Treasury Department published proposed guidance last week for claiming the clean fuel tax credit — one of the few energy subsidies that was expanded, rather than diminished, by Trump’s One Big Beautiful Bill Act. There was little of note in the proposal, since many of the higher-stakes climate-related decisions about the tax credit were made by Congress in the statute itself. But it did clear up one point of uncertainty: The guidance indicates that the administration will reward biofuel crops cultivated using “climate-smart agriculture” practices.
On the one hand, it’s a somewhat surprising development simply because of Trump’s record of cutting anything with climate in the title. Last April, the U.S. Department of Agriculture terminated grants from a Biden-era “Climate-Smart Commodities” program, calling it a “slush fund,” and refashioned it into the “Advancing Markets for Producers” initiative.
On the other hand, depending on how the Trump administration implements it, integrating climate-smart agriculture into the clean fuel tax credit could become its own kind of slush fund, paying out billions in taxpayer dollars for questionable benefits and with little accountability.
The clean fuel tax credit, known by its section of the tax code as 45Z, subsidizes the production of low-carbon transportation fuels for vehicles and aviation. Companies can earn up to $1 per gallon depending on the carbon intensity of the production process.
Sourcing corn and soy from farms that use climate-smart agriculture practices is one potential way for biofuel producers to claim more of the credit. “Climate-smart agriculture” can refer to a wide variety of techniques that increase the amount of soil stored in carbon or otherwise reduce emissions, such as reducing soil disturbance, planting cover crops, or implementing nutrient management practices that reduce nitrous oxide emissions. But to date, the federal government has not issued guidance for how to account for these practices.
The Biden administration put out proposed rules just before leaving office that were quite controversial, Nikita Pavlenko, the fuels and aviation program director at the International Council on Clean Transportation, told me. The methodology relied entirely on modeling and did not require farmers to take any real-life measurements of soil carbon before or after adopting the climate-smart practice. The rules also assume that these climate-smart practices would be implemented anew, when in reality many farms have been practicing some of them for years without subsidies. That means ethanol producers could potentially get free money to buy corn from farms that adopted no-till practices long ago, with no additional benefit for the climate.
“These climate-smart ag practices are a rare example of bipartisanship, for what it’s worth, and there’s a lot of money to be made in it,” Pavlenko told me. “But I’m not sure exactly how much actual greenhouse gas reduction or sequestration.”
According to estimates by Pavlenko’s group, the lack of an additionality requirement could lead to the government paying $2.1 billion in subsidies for farms to keep doing what they were already doing, with no new benefits for the climate.
I should note that the climate integrity of the clean fuel tax credit, also known as 45Z, was already compromised by changes made in the OBBBA. Subsidies for crop-based biofuels can indirectly drive deforestation. Prior to Trump’s tax law, producers would have had to take into account emissions related to land use changes when they calculated the carbon intensity of their fuel. Now they don’t. The change will make it much easier for a fuel like ethanol, which is already heavily subsidized through other programs, to qualify.
That, in turn, could cost taxpayers an estimated five times as much per year. When the subsidy was first created in the Inflation Reduction Act, the Joint Committee on Taxation estimated that it would cost taxpayers $2.9 billion over three years. After the OBBBA passed, extending the credit by two years, the committee’s estimate was $25.7 billion.
The existing proposal for incorporating climate-smart agriculture practices into the tax credit calculation would likely push that estimate even higher. After the Biden administration released its proposal last January, groups like Pavlenko’s submitted comments critiquing the methods and suggesting changes. But after the Trump administration took over, it was unclear what would happen with it, he said.
Last week’s guidance was still somewhat vague about what’s next for the climate-smart agriculture calculations, saying only that the proposal published in January is still “undergoing testing, peer review, and public comment,” and that the Treasury expects it to be ready some time in 2026. In the meantime, the Treasury will be taking public comments on the broader 45Z guidance through April 6 and hold a public hearing on May 28.
On Tesla’s sunny picture, Chinese nuclear, and Bad Bunny’s electric halftime show
Current conditions: The Seattle Seahawks returned home to a classically rainy, overcast city from their win in last night’s Super Bowl, though the sun is expected to come out for Wednesday's victory parade • Severe Tropical Cyclone Mitchell is pummeling Western Australia with as much as 8 inches of rain • Flash floods from Storm Marta have killed at least four in Morocco.
Orsted’s two major offshore wind projects in the United States are back on track to be completed on schedule, its chief executive said. Rasmus Errboe told the Financial Times that the Revolution Wind and Sunrise Wind projects in New England would come online in the latter half of this year and in 2027, respectively. “We are fully back to work and construction on both projects is moving forward according to plan,” Errboe said. The U.S. has lost upward of $34 billion worth of clean energy projects since President Donald Trump returned to office, as I wrote last week. A new bipartisan bill introduced in the House last week to reform the federal permitting process would bar the White House from yanking back already granted permits. For now, however, the Trump administration has signaled its plans to appeal federal courts’ decisions to rule against its actions to halt construction on offshore turbines.
The fight over the billions in federal funding the White House is holding up for the Gateway rail project between New Jersey and New York, meanwhile, heated up over the weekend. On Friday night, a federal judge ordered the Trump administration to unfreeze the nearly $16 billion to the project, just hours after construction ground to a halt as funding ran dry. In her ruling, U.S. District Judge Jeannette Vargas of the Southern District of New York wrote that “plaintiffs have adequately shown that the public interest would be harmed by a delay in a critical infrastructure project.” Trump had his own idea in mind. Over the weekend, the White House proposed releasing the money only if Senate Minority Leader Chuck Schumer of New York agreed to rename Penn Station after Trump.
Tesla has started hiring staff to ramp up production of solar panels as the company looks to build 100 gigawatts of panel-manufacturing capacity supplied with raw materials produced in America. In a job posting on LinkedIn, Seth Winger, Tesla’s senior manager for solar products engineering, wrote that the panel-producing buildout was “an audacious, ambitious project.” For that, he wrote, “we need audacious, ambitious engineers and scientists to help us grow to massive scale. If you want to solve tough manufacturing problems at breakneck speed and help the U.S. breakthrough on renewable energy generation, come join us.” One of the listings indicated that the target date for bringing the new factories online was the “end of 2028,” giving an indication of timing that Reuters noted had been previously absent from Elon Musk’s public statements. Bloomberg reported last week that Tesla is already looking at sites in New York, Arizona, and Idaho for its manufacturing expansion.
The Trump administration tried to yank permits from the offshore wind projects off New England on the grounds that the towering turbines caused more ecological destruction than the electricity is worth. On Friday, however, Trump signed a proclamation reopening a giant marine preserve in the Atlantic Ocean to commercial fishing. First established at the end of the Obama administration, the Northeast Canyons and Seamounts Marine National Monument lies 130 miles off the coast of Cape Cod, encompassing what The New York Times described as “an area the size of Connecticut that is home to dolphins, endangered whales, sea turtles, and ancient deep-sea corals.” While Trump lifted the ban on commercial fishing in the zone during his first administration, President Joe Biden reinstated the restrictions. But this isn’t the first time Trump reopened a national marine national monument to fishing. In April, he ended protections for the Pacific Islands Heritage Marine National Monument located 750 miles west of Hawaii and designated by President George W. Bush in 2009.

Connecitcut’s Department of Insurance has launched a website that displays extensive information about the climate risk of every property in the state in what E&E News called “an unprecedented move to alert residents and to promote flood insurance.” The details include each property’s history of damage from floods and other events predicted to get worse as the planet warms. “A single risk score does not fully convey flood and climate risk,” department spokesperson Mary Quinn said. The department plans a marketing campaign this year with ads on radio, TV, and social media, and workshops for insurance agents on how to use the website. Nationwide, climate change is already raising household costs by $900 per year, as Heatmap’s Matthew Zeitlin reported last year. Wildfires have already “destroyed California’s insurance market,” according to an interview with Heatmap's Shift Key podcast last year with an expert at the University of Pennsylvania’s Wharton School.
Unit 1 of the Taipingling nuclear power station in China’s Guangdong has reached criticality seven years after construction began on the gigawatt-sized Hualong One reactor. The debut atom-splitting means the newest reactor is months, if not weeks, from entering into commercial operation. If that enticingly single-digit number of years to build a piece of infrastructure that takes the U.S. more than a decade wasn’t enough of a sign of China’s nuclear strengths, the country this week hit another milestone on a separate atomic station. At the Zhangzhou-3 nuclear reactor, workers last week installed the inner steel dome of the containment building.

Nearly a decade after Puerto Rico’s power grid collapsed and plunged America’s most populous territory into the second-longest blackout in world history, the island’s biggest musical star performed a Super Bowl halftime show that included linemen working on transformers. Bad Bunny’s performance, a revue of his reggaeton hits, served as an ode to what he called “my motherland, my homeland, Puerto Rico.” The grid still suffers regular outages. When it’s working, the power system sends occasional surges through wires that fry appliances. Electricity rates are higher than almost any state, despite Puerto Rico suffering worse poverty rates than Mississippi. At one point, Bad Bunny climbed a utility pole on stage waving a light-blue Puerto Rican flag, a symbol of the movement to establish the island territory as its own independent nation. It was a powerful political statement at America’s most-watched sporting event. For energy nerds, it was a rare opportunity to reflect on one of the worst, most prolonged infrastructure disasters in modern American history.
Rob talks with the lawmaker from New Mexico (and one-time mechanical engineer) about the present and future of climate policy.
The permitting reform conversation is heating up.
On this week’s episode of Shift Key, Rob talks to Senator Martin Heinrich about whether Republicans and Democrats will reach a permitting reform deal this year. They chat about what Democrats would need to see in such a deal, how it could help transmission projects, and why such a deal will ultimately need to constrain President Trump in some way.
They also discuss the future of Democratic energy and climate policy — what Heinrich learned from the Biden administration, what the Inflation Reduction Act got right (and wrong), and why data centers are becoming a new kind of energy villain.
Heinrich is the senior senator from New Mexico (and a well-known transmission policy nerd). He’s also a trained mechanical engineer and the son of a utility lineman. Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University. Jesse is off this week.

Here is an excerpt from our conversation:
Robinson Meyer: There’s one bill we reported on yesterday at Heatmap called the FREEDOM Act. It just came out of the House. It has a bipartisan group behind it, including [Republican] Mike Lawler from New York and [Democrat] Adam Gray in California. It tries to prevent federal agencies from terminating work on a fully permitted project or affecting ongoing construction on a fully permitted project. And it would establish this fund that a company that has seen its permits get yanked could pull from in the Treasury Department, up to $5 million.
Does this bill meet your concerns? Have you looked at it? Is this the kind of text that you would need to see to say, okay, we could put a deal together?
Senator Martin Heinrich: We’re very intrigued in digging into that legislation right now, and I do think that anything we can do to create more certainty in the market — and that’s true for both renewables and for traditional energy. Because the truth is, we can’t have a system where, when one party controls the White House, they attack this set of energy, and then when it changes hands, that group attacks this other set of energy. We just need to set policy and then have predictable flows of capital into the market. And so I think this is a positive step forward. And we should look at all the things the House does and evaluate them on their merits.
I will say that if the figure is $5 billion for this fund, you could exhaust that on one wind project. And thank goodness the court stepped in as quickly as they did because those offshore wind projects were on the scale of tens of billions of dollars. And effectively, if you’re going shut those off, that’s a takings, in my view. That’s like actually stealing someone’s capital, stealing someone’s money.
And we can’t — that’s third world stuff. We can’t have that in the United States of America. But I give credit to the House for coming forward with this kind of thing because we do need to constrain it.
