Investing in red states doesn’t make defying Trump any safer.

In the end, it was what the letters didn’t say.
For months — since well before the 2024 election — when asked about the future health and safety of the clean energy tax credits in the Inflation Reduction Act, advocates and industry folks would point to the 20 or so House Republicans (sometimes more, sometimes fewer) who would sign on to public statements urging their colleagues to preserve at least some of the law. Better not to pull out the rug from business investment, they argued. Especially not investment in their districts.
These letters were “reassuring to a lot of folks in clean energy and climate communities,” Chris Moyer, the founder of Echo Communications and a former staffer for longtime Senate Majority Leader Harry Reid, told me.
“I never felt reassured,” Moyer added.
Plenty of people did, though. The home solar company Sunrun, for instance, told investors in a presentation earlier this month that a “growing number of Republicans in Congress — including 39 overall House members and four Senators — publicly support maintaining energy tax credits through various letters over the past few months.” The company added that “we expect a range of draft proposals to be issued, possibly including draconian scenarios, but we expect any extreme proposals will be moderated as they progress.”
Instead, the draft language got progressively worse for the residential solar industry, with the version that passed the House Thursday morning knocking billions of dollars off the sector, as tax credits were further squeezed to help make room for other priorities that truly posed an existential threat to the bill’s passage.
What Sunrun and others appear to have failed to notice — or at least publicly acknowledge — is that while these representatives wanted to see tax credits preserved, they never specified what they would do if their wishes were disregarded. Unlike the handful of Republicans who threatened to tank the bill over expanding the deduction for state and local taxes (each of whom signed one of the tax credit letters, at some point), or the Freedom Caucus, who tend to vote no on any major fiscal bill that doesn’t contain sizable spending cuts (so, until now, every budget bill), the tax credit Republicans never threatened to kill the bill entirely.
Ultimately, the only Republicans to outright oppose the bill did so because it didn’t cut the deficit enough. All of the House Republicans who signed letters or statements in support of clean energy tax credits voted yes on the legislation, with a single exception: New York’s Andrew Garbarino, who reportedly slept through the roll call. (He later said he would have voted for it had he been awake.)
“The coalition of interests effectively persuaded Republican members that tax credits were driving investment in their districts and states,” Pavan Venkatakrishnan, an infrastructure fellow at the Institute for Progress, told me in a text message. “Where advocates fell short was in convincing them that preserving energy tax credits — especially for mature technologies Republicans often view skeptically — should take precedence over preventing Medicaid cuts or addressing parochial concerns like SALT.”
The Inflation Reduction Act itself was, after all, advanced on a party-line basis, as was Biden’s 2021 American Rescue Plan. Combined, those two bills received a single Democratic no vote and no Republican yes votes.
In the end, Moyer said, Republican House members in the current Congress were under immense political pressure to support what is likely to be the sole major piece of legislation advanced this year by President Trump — one that contained a number of provisions, especially on SALT, that they agreed with.
“There are major consequences for individual house members who vote against the president’s agenda,” Moyer said. “They made a calculation. They knew they were going to take heat either way. They would rather take heat from clean energy folks and people affected by the projects.”
It wasn’t supposed to be this way.
White House officials and outside analysts frequently touted job creation linked to IRA investments in Republican House districts and states as a tangible benefit of the law that would make it politically impossible to overturn, even as Congress and the White House turned over.
“President’s Biden’s policies are leading to more than 330,000 new clean energy jobs already created, more than half of which are in Republican-held districts,” White House communications director Ben LaBolt told reporters last year, previewing a speech President Biden would give on climate change.
Even after Biden had been defeated, White House climate advisor Ali Zaidi told Bloomberg that “we have grown the political consensus around the Inflation Reduction Act through its execution,” citing one of the House Republican letters in support of the clean energy tax credits.
One former Biden White House climate official told me that having projects in Republican districts was thought by the IRA’s crafters to make the bill more politically sustainable — but only so much.
“A [freaking] battery factory is not going to save democracy,” the official told me, referencing more ambitious claims that the tax credits could lead to more Democratic electoral victories. (The official asked to remain anonymous in order not to jeopardize their current professional prospects.) Instead, “it was supposed to make it slightly harder for Republicans to overturn the subsidies.”
Congresspeople worried about jobs weren’t supposed to be the only things that would preserve the bill, either, the official added. Clean energy and energy-dependent sectors, they thought, should be able to effectively advocate for themselves.
To the extent that business interests were able to win a hearing with House Republicans, they were older, more traditionally conservative industries such as nuclear, manufacturing, agriculture, and oil and gas.The biofuels industry (i.e. liquid Big Agriculture) won an extension of its tax credit, 45Z. The oil and gas industry’s favored measure, the 45Q tax credit for carbon sequestration, was minimally fettered. Nuclear power was the one sector whose treatment notably improved between the initial draft from the House’s tax-writing committee and the version voted on Thursday. Advanced nuclear facilities can still claim tax credits if they start construction by 2029, while other clean energy projects have to start construction within 60 days of the bill’s passage and be in service by the end of 2028.
“I think these outcomes are unsurprising. In places where folks consistently engaged, things were protected,” a Republican lobbyist told me, referring to manufacturing, biofuels, and nuclear power, requesting anonymity because they weren’t authorized to speak publicly. “But assuming a project in a district would guarantee a no vote on a large package was always a mistake.”
“The relative success of nuclear is a testament to the importance of having strong champions — predictable but notable show of political might,” a second Republican lobbyist told me, who was also not allowed to speak publicly about the bill.
But all hope isn’t lost yet. The Senate still has to pass something that the House will agree with. Some senators had made noises about how nuclear, hydropower, and geothermal were treated in the initial language.
“Budget reconciliation is, first and foremost, a fiscal exercise,” Venkatakrishnan told me. “Energy tax credits offer a path of least resistance for hitting lawmakers’ fiscal targets. As the Senate takes up this bill, the case must be made that the marginal $100 billion to $200 billion in cuts seriously jeopardizes grid reliability and energy innovation.” Whether that will be enough to generate meaningful opposition in the Senate, however, is the $600 billion question.

The fourth-generation gas-cooled reactor company ZettaJoule is setting up shop at an unnamed university.
The appeal of next-generation nuclear technology is simple. Unlike the vast majority of existing reactors that use water, so-called fourth-generation units use coolants such as molten salt, liquid metal, or gases that can withstand intense heat such as helium. That allows the machines to reach and maintain the high temperatures necessary to decarbonize industrial processes, which currently only fossil fuels are able to reach.
But the execution requirements of these advanced reactors are complex, making skepticism easy to understand. While the U.S., Germany, and other countries experimented with fourth-generation reactors in earlier decades, there is only one commercial unit in operation today. That’s in China, arguably the leader in advanced nuclear, which hooked up a demonstration model of a high-temperature gas-cooled reactor to its grid two years ago, and just approved building another project in September.
Then there’s Japan, which has been operating its own high-temperature gas-cooled reactor for 27 years at a government research site in Ibaraki Prefecture, about 90 minutes north of Tokyo by train. Unlike China’s design, it’s not a commercial power reactor. Also unlike China’s design, it’s coming to America.
Heatmap has learned that ZettaJoule, an American-Japanese startup led by engineers who worked on that reactor, is now coming out of stealth and laying plans to build its first plant in Texas.
For months, the company has quietly staffed up its team of American and Japanese executives, including a former U.S. Nuclear Regulatory Commission official and a high-ranking ex-administrator from the industrial giant Mitsubishi. It’s now preparing to decamp from its initial home base in Rockville, Maryland, to the Lone Star State as it prepares to announce its debut project at an as-yet-unnamed university in Texas.
“We haven’t built a nuclear reactor in many, many decades, so you have only a handful of people who experienced the full cycle from design to operations,” Mitsuo Shimofuji, ZettaJoule’s chief executive, told me. “We need to complete this before they retire.”
That’s where the company sees its advantage over rivals in the race to build the West’s first commercial high-temperature gas reactor, such as Amazon-backed X-energy or Canada’s StarCore nuclear. ZettaJoule’s chief nuclear office, Kazuhiko Kunitomi, oversaw the construction of Japan’s research reactor in the 1990s. He’s considered Japan’s leading expert in high-temperature gas reactors.
“Our chief nuclear officer and some of our engineers are the only people in the Western world who have experience of the whole cycle from design to construction to operation of a high temperature gas reactor,” Shimofuji said.
Like X-energy’s reactor, ZettaJoule’s design is a small modular reactor. With a capacity of 30 megawatts of thermal output and 12 megawatts of electricity, the ZettaJoule reactor qualifies as a microreactor, a subcategory of SMR that includes anything 20 megawatts of electricity or less. Both companies’ reactors will also run on TRISO, a special kind of enriched uranium with cladding on each pellet that makes the fuel safer and more efficient at higher temperatures.
While X-energy’s debut project that Amazon is financing in Washington State is a nearly 1-gigawatt power station made up of at least a dozen of the American startup’s 80-megawatt reactors, ZettaJoule isn’t looking to generate electricity.
The first new reactor in Texas will be a research reactor, but the company’s focus is on producing heat. The reactor already working in Japan, which produces heat, demonstrates that the design can reach 950 degrees Celsius, roughly 25% higher than the operating temperature of China’s reactor.
The potential for use in industrial applications has begun to attract corporate partners. In a letter sent Monday to Ted Garrish, the U.S. assistant secretary of energy in charge of nuclear power — a copy of which I obtained — the U.S. subsidiary of the Saudi Arabian oil goliath Aramco urged the Trump administration to support ZettaJoule, and said that it would “consider their application to our operations” as the technology matures. ZettaJoule is in talks with at least two other multinational corporations.
The first new reactor ZettaJoule builds won’t be identical to the unit in Japan, Shimofuji said.
“We are going to modernize this reactor together with the Japanese and U.S. engineering partners,” he said. “The research reactor is robust and solid, but it’s over-engineered. What we want to do is use the safety basis but to make it more economic and competitive.”
Once ZettaJoule proves its ability to build and operate a new unit in Texas, the company will start exporting the technology back to Japan. The microreactor will be its first product line.
“But in the future, we can scale up to 20 times bigger,” Shimofuji said. “We can do 600 megawatts thermal and 300 megawatts electric.”
Another benefit ZettaJoule can tap into is the sweeping deal President Donald Trump brokered with Japanese Prime Minister Sanae Takaichi in October, which included hundreds of billions of dollars for new reactors of varying sizes, including the large-scale Westinghouse AP1000. That included financing to build GE Vernova Hitachi Nuclear Energy’s 300-megawatt BWRX-300, one of the West’s leading third-generation SMRs, which uses a traditional water-cooled design.
Unlike that unit, however, ZettaJoule’s micro-reactor is not a first-of-a-kind technology, said Chris Gadomski, the lead nuclear analyst at the consultancy BloombergNEF.
“It’s operated in Japan for a long, long time,” he told me. “So that second-of-a-kind is an attractive feature. Some of these companies have never operated a reactor. This one has done that.”
A similar dynamic almost played out with large-scale reactors more than two decades ago. In the late 1990s, Japanese developers built four of GE and Hitachi’s ABWR reactor, a large-scale unit with some of the key safety features that make the AP1000 stand out compared to its first- and second-generation predecessors. In the mid 2000s, the U.S. certified the design and planned to build a pair in South Texas. But the project never materialized, and America instead put its resources into Westinghouse’s design.
But the market is different today. Electricity demand is surging in the near term from data centers and in the long term from electrification of cars and industry. The need to curb fossil fuel consumption in the face of worsening climate change is more widely accepted than ever. And China’s growing dominance over nuclear energy has rattled officials from Tokyo to Washington.
“We need to deploy this as soon as possible to not lose the experienced people in Japan and the U.S.,” Shimofuji said. “In two or three years time, we will get a construction permit ideally. We are targeting the early 2030s.”
If every company publicly holding itself to that timeline is successful, the nuclear industry will be a crowded field. But as history shows, those with the experience to actually take a reactor from paper to concrete may have an advantage.
It’s now clear that 2026 will be big for American energy, but it’s going to be incredibly tense.
Over the past 365 days, we at The Fight have closely monitored numerous conflicts over siting and permitting for renewable energy and battery storage projects. As we’ve done so, the data center boom has come into full view, igniting a tinderbox of resentment over land use, local governance and, well, lots more. The future of the U.S. economy and the energy grid may well ride on the outcomes of the very same city council and board of commissioners meetings I’ve been reporting on every day. It’s a scary yet exciting prospect.
To bring us into the new year, I wanted to try something a little different. Readers ask me all the time for advice with questions like, What should I be thinking about right now? And, How do I get this community to support my project? Or my favorite: When will people finally just shut up and let us build things? To try and answer these questions and more, I wanted to give you the top five trends in energy development (and data centers) I’ll be watching next year.
The best thing going for American renewable energy right now is the AI data center boom. But the backlash against developing these projects is spreading incredibly fast.
Do you remember last week when I told you about a national environmental group calling for data center moratoria across the country? On Wednesday, Senator Bernie Sanders called for a nationwide halt to data center construction until regulations are put in place. The next day, the Working Families Party – a progressive third party that fields candidates all over the country for all levels of government – called for its candidates to run in opposition to new data center construction.
On the other end of the political spectrum, major figures in the American right wing have become AI skeptics critical of the nascent data center buildout, including Florida Governor Ron DeSantis, Missouri Senator Josh Hawley, and former Trump adviser Steve Bannon. These figures are clearly following the signals amidst the noise; I have watched in recent months as anti-data center fervor has spread across Facebook, with local community pages and groups once focused on solar and wind projects pivoting instead to focus on data centers in development near them.
In other words, I predicted just one month ago, an anti-data center political movement is forming across the country and quickly gaining steam (ironically aided by the internet and algorithms powered by server farms).
I often hear from the clean energy sector that the data center boom will be a boon for new projects. Renewable energy is the fastest to scale and construct, the thinking goes, and therefore will be the quickest, easiest, and most cost effective way to meet the projected spike in energy demand.
I’m not convinced yet that this line of thinking is correct. But I’m definitely sure that no matter the fuel type, we can expect a lot more transmission development, and nothing sparks a land use fight more easily than new wires.
Past is prologue here. One must look no further than the years-long fight over the Piedmont Reliability Project, a proposed line that would connect a nuclear power plant in Pennsylvania to data centers in Virginia by crossing a large swathe of Maryland agricultural land. I’ve been covering it closely since we put the project in our inaugural list of the most at-risk projects, and the conflict is now a clear blueprint.
In Wisconsin, a billion-dollar transmission project is proving this thesis true. I highly recommend readers pay close attention to Port Washington, where the release of fresh transmission line routes for a massive new data center this week has aided an effort to recall the city’s mayor for supporting the project. And this isn’t even an interstate project like Piedmont.
While I may not be sure of the renewable energy sector’s longer-term benefits from data center development, I’m far more confident that this Big Tech land use backlash is hitting projects right now.
The short-term issue for renewables developers is that opponents of data centers use arguments and tactics similar to those deployed by anti-solar and anti-wind advocates. Everyone fighting data centers is talking about ending development on farmland, avoiding changes to property values, stopping excess noise and water use, and halting irreparable changes to their ways of life.
Only one factor distinguishes data center fights from renewable energy fights: building the former potentially raises energy bills, while the latter will lower energy costs.
I do fear that as data center fights intensify nationwide, communities will not ban or hyper-regulate the server farms in particular, but rather will pass general bans that also block the energy projects that could potentially power them. Rural counties are already enacting moratoria on solar and wind in tandem with data centers – this is not new. But the problem will worsen as conflicts spread, and it will be incumbent upon the myriad environmentalists boosting data center opponents to not accidentally aid those fighting zero-carbon energy.
This week, the Bureau of Land Management approved its first solar project in months: the Libra facility in Nevada. When this happened, I received a flood of enthusiastic and optimistic emails and texts from sources.
We do not yet know whether the Libra approval is a signal of a thaw inside the Trump administration. The Interior Department’s freeze on renewables permitting decisions continues mostly unabated, and I have seen nothing to indicate that more decisions like this are coming down the pike. What we do know is that ahead of a difficult midterm election, the Trump administration faces outsized pressure to do more to address “affordability,” Democrats plan to go after Republicans for effectively repealing the Inflation Reduction Act and halting permits for solar and wind projects, and there’s a grand bargain to be made in Congress over permitting reform that rides on an end to the permitting freeze.
I anticipate that ahead of the election and further permitting talks in Congress, the Trump administration will mildly ease its chokehold on solar and wind permits because that is the most logical option in front of them. I do not think this will change the circumstances for more than a small handful of projects sited on federal lands that were already deep in the permitting process when Trump took power.
It’s impossible to conclude a conversation about next year’s project fights without ending on the theme that defined 2025: battery fire fears are ablaze, and they’ll only intensify as data centers demand excess energy storage capacity.
The January Moss Landing fire incident was a defining moment for an energy sector struggling to grapple with the effects of the Internet age. Despite bearing little resemblance to the litany of BESS proposals across the country, that one hunk of burning battery wreckage in California inspired countless communities nationwide to ban new battery storage outright.
There is no sign this trend will end any time soon. I expect data centers to only accelerate these concerns, as these facilities can also catch fire in ways that are challenging to address.
Plus a resolution for Vineyard Wind and more of the week’s big renewables fights.
1. Hopkins County, Texas – A Dallas-area data center fight pitting developer Vistra against Texas attorney general Ken Paxton has exploded into a full-blown political controversy as the power company now argues the project’s developer had an improper romance with a city official for the host community.
2. La Plata County, Colorado – This county has just voted to extend its moratorium on battery energy storage facilities over fire fears.
3. Dane County, Wisconsin – The city of Madison appears poised to ban data centers for at least a year.
4. Goodhue County, Minnesota – The Minnesota Center for Environmental Advocacy, a large environmentalist organization in the state, is suing to block a data center project in the small city of Pine Island.
5. Hall County, Georgia – A data center has been stopped down South, at least for now.
6. Dukes County, Massachusetts – The fight between Vineyard Wind and the town of Nantucket seems to be over.
