See also: federal policy, batteries, and electricity demand.

The clean energy industry is beginning to report to investors and the public on its first brush with Donald Trump’s trade policy. While earnings season has only just begun, already some broad themes are emerging across the sector: Tariffs hurt. Batteries are getting more expensive. And there’s big demand for power, especially natural gas.
Four big clean energy companies that have reported results so far — inverter and battery maker Enphase, turbine manufacturer GE Vernova, electric vehicle giant Tesla, and developer and utility NextEra — mentioned tariffs prominently in either their earnings reports or their analyst calls. GE Vernova said that tariffs would result in $300 million to $400 million of additional costs. Enphase said that tariffs would take off two percentage points from its margin in the second quarter and six to eight points of gross margin in the third quarter. Tesla said that “increasing tariffs may cause market volatility and near-term impacts to supply and demand.”
Tesla’s executives — including chief executive Elon Musk — expanded on that market volatility later in a call with investors and analysts, with Musk saying that he was an “advocate of predictable tariff structures, free trade, and lower tariffs.” Musk added that economic uncertainty could continue to weigh on Tesla’s auto sales, which notably declined in the first three months of the year. “When there is economic uncertainty, people generally want to pause on doing a major capital purchase like a car,” he observed.
NextEra chief executive John Ketchum said the company had “dramatically diversified where we source our solar panels” and was not affected by the recent announcement of high tariff rates on solar panels from Southeast Asia. He also specified to analysts that “we source our wind turbines from the U.S., with manufacturing in Florida.” The company estimated that it has “$150 million in tariff exposure through 2028, on over $75 billion in expected capital spend,” Ketchum said.
Enphase chief executive Badri Kothandaraman attempted to tread delicately on the tariff issue. “While the global policy environment remains fluid with tariffs, with interest rates and subsidies constantly evolving, we are moving quickly to realign our supply chain to minimize downside across a range of scenarios,” he said. “While we cannot control the macroeconomic conditions, we can absolutely control our response.” GE Vernova chief financial officer Ken Parks described tariffs as a “continued increase in the cost base,” and said that the combined tariffs on steel plus various imports from Canada, Mexico, China — which is facing import duties of 145% or more, depending on the product — affect about a quarter of its spending.
A lot of that tariff impact comes from the battery supply chain, which China dominates. For Tesla, that means its fast growing energy storage business is particularly at risk. While the company has made some efforts to onshore stationary storage battery production, its chief financial officer, Vaibhav Taneja, said that domestic production would ultimately account for only a “fraction” of its battery needs, and even that would “take time.”
Enphase was similarly upfront about the impact on its battery supplies. “We are no exception. We use Chinese sources for the cell packs,” Kothandaraman said. He explained that thanks to the tariffs, making batteries domestically with Chinese cells “therefore turns out for us that whether we make it domestically or whether we make it outside the U.S., our costs are becoming approximately the same. And the cost impact is significant.” In other words, the tariffs make domestic battery production less appealing than it was before. Kothandaraman said that the company is working on establishing a non-Chinese supply chain, which will take six to nine months.
NextEra’s Ketchum said that the company had made “arrangements” to buy batteries made in the U.S. “for a significant portion of our backlog,” and that its contracts for non-Chinese-sourced batteries required the supplier to cover any tariff-related costs. Ketchum did say that the domestic batteries meet local content requirements for tax subsidies under the Inflation Reduction Act, however “there are certain components that come in from outside the United States.” Overall, Ketchum said, “our tariff exposure on batteries is expected to be negligible.”
All four companies are heavily exposed to various energy regulatory and subsidy plans that may or may not survive the double-whammy of the congressional Republicans’ budget-making priorities and the Trump administration’s desire to roll back environmental regulations.
Tesla’s revenue from emissions credits that other carmakers buy to comply with California’s fleet emissions standards was $595 million in the first quarter of this year, compared to $409 million of net income — implying that the company would have lost money if not for the credits. This Trump administration has already attempted to take away California’s ability to set emissions standards, as it did the first time around. Then it was not successful, and this time it might not have to be — the Supreme Court on Wednesday indicated that it would be open to a lawsuit from the fossil fuel industry challenging California’s limits.
Kothandaraman said that “the lack of certainty” around the fate of the Inflation Reduction Act, which is currently being hashed out in Congress, “is definitely a factor” in explaining what one analyst described as “a bit of paralysis on the customer side.” He was hopeful that “demand will be unlocked” once there’s “clarity” on IRA tax credits.
Meanwhile, GE Vernova said that offshore wind orders had fallen by 43%, “as a result of ongoing U.S. policy uncertainty and permitting delays.” It also took a $70 million charge related to the cancellation of a deal to supply 18-megawatt turbines in New York.
Musk bragged that Tesla’s Megapack utility storage system “enables utility companies to output far more total energy than would otherwise be the case,” and that “utility companies are beginning to realize this and are buying in our Megapacks at scale.” While the company deployed almost 40 gigawatt-hours of battery storage in the past 12 months — an impressive amount based on the current level of grid battery storage in the U.S. — Musk predicted that Tesla could end up deploying “terawatts” of storage on an annual basis.
NextEra has a large renewables development business, and Ketchum sees the uptick in demand for electricity as a boon: “When I look at the demand and the outlook in the renewable sector going … we just continue to see strong demand across the board, with hyperscalers being a nice sized part of that.”
GE Vernova competed with NextEra for the most investor-friendly demand growth story — though its is not a particularly climate-friendly one. The company says it has a backlog of 29 gigawatts of natural gas turbine orders, with an additional 21 gigawatts of reservations that will turn into future production. Its earnings before interest, taxes, depreciation, and amortization for its power business jumped from $345 million in the first quarter of last year to $508 million in the first quarter of this year, while its margins grew from 8.6% to 11.5%.
About a third of its reservations for turbines are for data centers, Scott Strazik, the company’s chief executive said. Some more were to provide baseload power. And the rest? “A healthy amount of these are also F-class gas turbines to just strengthen the durability and the resiliency on the grid,” he said.

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.
