If the “nuclear renaissance” is here, it’s happening only in certain kinds of places. California and New York aren’t getting new reactors capable of generating massive amounts of always-on, carbon-free power — instead projects are being completed and planned in Tennessee, Georgia, and Idaho. It’s not all red state friendliness to new development and blue state fears of nuclear waste either. It’s really about how electricity markets are organized across the United States.
There’s simply little new nuclear activity in the vast swaths of the country, like much of the Northeast and Midwest, Texas, and California, where electricity markets have been partially or completely “deregulated,” meaning that utilities largely buy electricity from generators and distribute it to consumers in something like a free market. Instead, nuclear projects are popping up in markets, like those in the South and Mountain West, where utilities still control both electricity generation (think power plants) and the distribution of that electricity to customers and where public power companies can still predominate in the market. In these areas, energy companies have the scale, authority, access to investment, and captive customer base necessary to embark on capital intensive projects like nuclear generators.
This is of note because the Department of Energy estimates that in order to decarbonize the power system, some 550 to 770 gigawatts of new clean firm capacity, meaning generators that can be turned on 24/7, will be necessary. While this could include geothermal, solar or wind paired with batteries, or pumped hydro, there’s already some 94 gigawatts of existing nuclear capacity that the Energy Department anticipates could scale to around 300 gigawatts by 2050.
Where that’s been expanded recently is not necessarily the parts of the country that have an aggressive mandate to decarbonize.
Consider Georgia’s Vogtle-3 reactor, the United States’ first new nuclear reactor in years. The end result is a staggering amount of non-carbon-emitting power, but delivered at an eye-wateringly high cost (some $16 billion overbudget) in a market set-up where an investor-owned, vertically integrated utility — Georgia Power, a subsidiary of Southern Company — is able to charge ratepayers for high construction costs. Or Watts Bar Unit 2, a new reactor built by the Tennessee Valley Authority, a government power company with a monopoly on electricity in Tennessee and bordering states (it had its own set of delays — for decades — and cost overruns).
A similar dynamic is at work when it comes to the next generation of nuclear technology. The Carbon Free Power Project is a planned set of small modular reactors at the Idaho National Laboratory that a coalition of Mountain West public utilities have been working on and hope to make operational by the end of the decade.
The dream of small modular reactors is that, by standardizing construction processes and parts and also by literally making the projects smaller, construction costs for nuclear power can be brought down as more projects get completed. That being said, the Carbon Free Power Project has still reported large cost escalations. And it’s doing so with funding from the Department of Energy that could amount to around $1.3 billion of the over $9 billion it’s expected to cost if the project actually starts generating power as scheduled in 2029. Some members of the coalition have already dropped out and the projected price of power generated by the reactors has increased.
That’s not a huge surprise. Cost is really what’s holding back nuclear power.
The great scaling of renewable power across the country has been, its advocates always like to say, a triumph of the market. Wind and solar projects, while expensive to set up, are cheap to operate over time, in part because they have no fuel costs, compared to thermal plants which must acquire and combust coal, oil, or natural gas. In fact, around two thirds of the price of natural gas-generated power comes from the fuel itself, which actually hasn’t been a huge problem for natural gas over the past 15 years since it’s been so cheap.
On the other hand, the vast majority of the costs of nuclear power come from the expense of building its generators, according to an analysis by Brian Potter, a fellow at the Institute for Progress and a contributor to Heatmap. With gargantuan capital requirements and long construction timelines, interest payments on financing can end up doubling the total costs of nuclear plants. When those costs get reflected in the price of nuclear energy on so-called deregulated electricity markets, it becomes uncompetitive.
Regulated markets are a different story, however. Utilities that own power plants have massive cash flows and legally mandated profits that let them borrow huge amounts of money at the lower costs necessary to finance large, capital-intensive construction projects like nuclear plants — and then put the costs directly into ratepayers' bills.
“These larger utilities have a larger balance sheet, they can carry a larger project on their books without it being a huge percentage of their net debt at any point in time,” Adam Stein, the director of the Nuclear Energy Innovation program at the Breakthrough Institute, told me. The Tennessee Valley Authority also has a large capacity to carry debt, while public power companies “have experience and expertise internally in how to engage in the DOE grant process,” Stein said.
Critics of deregulation and advocates for nuclear power argue that the way those markets work does not properly value power that is not variable, like wind and solar, and can keep their fuel stored on site, unlike gas, which relies on pipelines. Despite the unique role it can play on the grid, nuclear power still has to compete on the same playing field as other assets which are intermittent or rely on getting fuel, Stein explained.
But utilities that control both generation and distribution aren’t immune from market forces, even if they can withstand them better. One reason why deregulation took hold in much of the county is precisely because there was so much backlash to utilities’ nuclear power plant projects that were more expensive than projected and assumed more electricity demand than there actually was.
“The ratepayers were paying a lot for the nuclear plants, and they were unhappy with it,” Meredith Angwin, an energy analyst and critic of deregulation, told me. “Cost per megawatt of nuclear plants, it’s just rising. There’s a learning curve that makes things less expensive — with nuclear it goes the other way.” Figuring out exactly why this happened — and how to reverse it — has been the great challenge of the nuclear industry and energy policy experts.
Many advocates for increased use of nuclear power see new construction techniques, plant designs, and more well-tailored regulation as the answer to these rising costs.
And while there have been large declines in the cost of renewables over the past decade, wind and solar projects have run into cost issues recently thanks to economy-wide inflation and specific issues with supply chains.
Offshore wind in the United States, which currently has a few dozen megawatts of capacity that the Biden administration wants to scale up to 30 gigawatts, is facing a crisis of high costs, with wind developers demanding more money to complete projects and even threatening to cancel them altogether, lest they get access to more subsidies. It’s a story we’ve heard before.

The CEO of Cleveland Cliffs is just the latest U.S. voice to affirm the dirtiest fossil fuel’s unexpectedly bright future.
While the story of coal demand has been largely about rapid industrialization in Asia — especially India and China — the United States under President Trump has been working hard to make itself a main character.
Case in point is in Middletown, Ohio, where a one-time clean steel project may be refashioned as a standard-bearer for an industry-driven U.S. coal revival. The company behind the project, Cleveland-Cliffs, won a Biden-era award of up to $500 million to develop and deploy hydrogen-based technology for iron and steel production. CEO Laurenco Goncalves began casting doubt on that project as long ago as September, when he told Politico that he was struggling to find buyers willing to pay more for low-carbon materials, and that he wasn’t sure the project “even makes sense with the grants.” Earlier this year, he told investors that the company was working with the Department of Energy to “explore changes in scope to better align with the administration’s energy priorities.”
During an earnings call Monday morning, Goncalves said the company had scrapped the project not because of the DOE, but rather because it was unable to get sufficient hydrogen for use as fuel.
“The very first thing: It’s clear by now that we will not have availability of hydrogen. So there is no point in pursuing something that we know for sure that’s not going to happen,” Goncalves said. “We informed the DOE that we would not be pursuing that project.”
Instead, the company has had “a very good conversation” with the DOE “on revamping that project in a way that we preserve and enhance Middletown using beautiful coal, beautiful coke,” Goncalves said. (Where have we heard that kind of language before?) “We are vertically integrated, and we use American iron ore and American coal and American natural gas as feedstock, all produced right here in the United States of America, employing American workers,” he added.
The evidence for coal’s stubborn persistence globally has been mounting for years. In 2021, the International Energy Agency forecast that by 2024, annual coal demand would hit an all-time high of just over 8,000 megatons. In 2024, it reported that coal demand in 2023 was already at 8,690 megatons, a new record; it also pushed out its prediction for a demand plateau to 2027, at which point it predicted annual demand would be 8,870 megatons.
The IEA largely chalked up the results to the world’s energy needs, writing that “the power sector has been the main driver of coal demand growth, with electricity generation from coal set to reach an all-time high of 10 700 terawatt-hours (TWh) in 2024.”
More recent analyses confirm that power demand, especially in Asia, could prop up global coal demand possibly for decades.
“Coal-fired power could be a bigger part of the energy mix for longer than expected, scuppering efforts to meet climate change goals,” a pair of Wood Mackenzie analysts, David Brown and Anthony Knutson, wrote in a report last week, echoing the IEA’s findings. China alone is responsible for almost three-quarters of global coal consumption, according to Wood Mackenzie. “New realities for energy markets in recent years have become more, not less, supportive of coal-fired power,” Brown and Knutson write.
The analysts put peak global coal demand a year earlier than the IEA, at 2026. But they also noted that “coal demand has consistently proven more resilient than expected.”
It’s possible that these fast-growing Asian nations could, for reasons of energy security or economy, decide to keep younger coal plants active for decades while extending the life of older plants to keep costs down. In this scenario, much of the world largely transitions away from using coal for power generation, but thanks to persistent Asian demand, global coal demand peaks as late as 2030. That could mean an extra 2 billion tons of greenhouse gas emissions compared to a base case scenario.
The U.S. federal government, meanwhile, has taken on a role as both a coal-friendly analyst and an active promoter of every facet of the industry.
A couple of weeks ago, a Department of Energy report declared that “absent intervention, it is impossible” for the U.S. to power the growth of the artificial intelligence industry “while maintaining a reliable power grid and keeping energy costs low for our citizens.” That energy-poor status quo, the DOE argued, was due in part to scheduled retirements of coal-fired generation.
The DOE has been doing its part to keep that generation online, using its emergency authorities to keep some coal plants open. It has joined President Trump in becoming a kind of all-purpose pitch man for the industry. Over the weekend, the Department’s X account posted an image of Secretary of Energy Chris Wright with a shovel, copied and pasted in front of an open-pit mine, with the words “MINE, BABY, MINE.”
On the supply side, congressional Republicans tucked into the One Big Beautiful Bill Act a tax credit specifically for domestic metallurgical coal production, which could be worth hundreds of millions of dollars a year.
Some of the largest end users of U.S.-mined metallurgical coal are outside the U.S., including the countries driving worldwide coal demand. India imported over 3 million tons of U.S. metallurgical coal in the first three months of 2025, with China just under a million, according to U.S. Energy Information Administration data.
The tie-up between Nippon Steel and U.S. Steel authorized in June, meanwhile, grants a “golden share” of the American company to the U.S. government, in part to ensure increased investment and capacity. That deal also explicitly provides for at least $1 billion of investment into U.S. Steel’s existing blast furnace operation, Mon Valley Works, in Western Pennsylvania. The investments “ensure Mon Valley Works operates for decades to come,” the company said in an announcement.
That means more coal: Mon Valley Works is the “largest coke manufacturing facility in the United States,” according to U.S. Steel, producing 4.3 million tons of the coal product both for its own operations and for sale to other steelmakers.
In an interview with Japanese media, Nippon Steel’s chief executive Eiji Hashimoto said that the newly expanded company will likely build a new steel mill in the U.S., as part of its goal to catch up in steel production with its Chinese rival China Baowu Steel Group Corp, while also using more of its existing capacity to increase production, hoping to eventually more than double its output by the middle of next decade.
(For what it’s worth, Japan is also a major importer of metallurgical coal from the United States, taking in just over a million tons in the first three months of 2025.)
While the future of coal will be determined in Asia, the U.S. steel industry is happy to work with the Trump administration and the coal industry to keep things burning.
“They see the value in blast furnaces just as we at Cleveland Cliffs do,” Cleveland-Cliffs’ Goncalves said of the U.S. industry’s new Japanese partners.
On betrayed regulatory promises, copper ‘anxiety,’ and Mercedes’ stalled EV plans
Current conditions: Typhoon Wipha is barrelling through southern China, making its way across the mainland after pummeling Hong Kong with heavy rain • More than 60 million Americans are facing heat alerts as temperatures surge • The unusually warm 21-degree Fahrenheit temperature recorded at Summit Station in Greenland is just a few degrees off a record high.

The Environmental Protection Agency announced plans on Friday afternoon to shut down its research arm and fire hundreds of biologists, chemists, toxicologists, and other scientists whose work helps determine safe pollution levels for regulations. The announcement comes after months of denials from EPA administrator Lee Zeldin that he planned to close the division in question, the Office of Research and Development, which studies the threat from climate change, toxic chemicals, and air and water pollution on human health, and funds university research programs.
The closure comes as part of deep job cuts at the agency. In a statement on Friday, Zeldin said the more than 500 layoffs — which, combined with voluntary buyouts, will slash the EPA’s workforce by nearly one-quarter compared to January’s numbers — would save taxpayers nearly $750 million. The nation’s biggest chemical manufacturers’ lobby agreed, arguing to NPR that the cuts would “ensure American taxpayer dollars are being used efficiently and effectively.” But environmentalists warned that the cuts would “not only cripple EPA’s ability to do its own research, but also to apply the research of other scientists.”
Shares in non-Chinese producers of graphite surged on Friday after the Trump administration slapped new anti-dumping duties of 93.5% on imports of the key mineral for batteries, the Financial Times reported. Combined with existing tariffs on Chinese materials, the new trade levies total more than 160%, according to the consultancy Benchmark Minerals. In response, the stock price for Australia-listed Syrah Resources, the world’s largest non-Chinese graphite miner and the developer behind a key Inflation Reduction Act-funded project in Louisiana, shot up 22%. Canada’s Nouveau Monde Graphite spiked 26%. The dual-listed Australian-U.S. producer Novonix surged 15%.
Not all of President Donald Trump’s mineral tariffs are causing excitement for U.S. allies. Earlier this month, the White House announced 50% tariffs on copper to begin in August, but it has yet to clarify whether those tariffs will apply to refined metal, semi-refined products, or copper ore. The uncertainty is causing “anxiety,” Máximo Pacheco, the chairman of Chile’s state-owned copper miner, told the FT. As Heatmap’s Matthew Zeitlin wrote when the tariffs were first announced, they have the potential to “provide renewed impetus to expand copper mining in the United States. But tariffs can happen in a matter of months. A copper mine takes years to open — and that’s if investors decide to put the money toward the project in the first place.”
Regulators in Virginia last week ordered electricity and natural gas provider Dominion to lay out a clearer blueprint for meeting the state’s legally-enshrined carbon-free electricity targets. But the State Corporation Commission still accepted the monopoly utility’s plans to build out more fossil fuel generation, Canary Media reported.
The Virginia Clean Economy Act, passed in 2020, requires Dominion to generate 100% of its electricity from carbon-free sources by 2045. The accepted plan runs up to 2039, leaving just six years to sort out the details of decarbonization. The regulators cautioned that “acceptance does not express approval.” While the statement stopped short of calling into question a proposed 944-megawatt gas complex just south of Richmond, Virginia’s capital, the commission said it would debate plans for another roughly 5 gigawatts of gas-burning power plants before approving construction..
British energy giant BP is selling off its U.S. onshore wind business as the Trump administration appears ready to smother the industry. On Friday, New York-based developer LS Power said it agreed to buy BP’s share of 10 wind projects totaling 1,700 megawatts of capacity. As part of the deal, LS Power plans to fold the wind projects into its renewable energy subsidiary, Clearlight Energy, increasing its fleet to 4,300 megawatts.
BP’s exit comes as the Trump administration has vowed to crack down on the expansion of wind and solar power in the U.S. Trump has long personally opposed wind energy, dating back to his unsuccessful fight against turbines erected near his golf course in Scotland before entering politics. Last week, Heatmap’s Jael Holzman reported on a memo from the Department of the Interior calling for political reviews of essentially all solar and wind developments in the U.S. This would at minimum stretch out the already challenging development timeline for projects, a problem especially as developers rush to qualify for federal tax credits.
Mercedes-Benz is pumping the brakes on U.S. production of its EQ line of electric vehicles as the Trump administration winds down federal tax credits to support purchases of battery-powered cars. The German automaker told InsideEVs that, by the start of September, it planned to temporarily pause assembly lines of all variants of its EQE and EQS sedans and SUVs that are either located in the U.S. or producing vehicles bound for the American market. The manufacturer is no longer taking orders from dealers for the cars.
Reviewers had criticized the EQ models for lacking the quality and sophistication of similar gas-powered lines of Mercedes vehicles. Even before Republicans in Congress rolled back the federal government’s landmark $7,500 tax credit for EVs, Mercedes faced trouble finding buyers. Sales of the EQS sedan and EQS SUV were down 52% in the U.S. in 2024 compared to the previous year. China’s biggest electric automakers, meanwhile, are racing to build factories in Brazil, the largest car market in South America.
Like tiny winged Magellans measuring barely an inch in size, the Bogong moth of Australia regularly travels more than 600 miles using celestial navigation, according to a new study in Nature. “The moths really are using a view of the night sky to guide their movements,” a researcher told Euronews.
From the Inflation Reduction Act to the Trump mega-law, here are 20 years of changes in one easy-to-read cheat sheet.
The landmark Republican reconciliation bill, which President Trump signed on July 4, has shattered the tax credits that served as the centerpiece of the country’s clean energy and climate policy.
Starting as soon as October, the law — which Trump has dubbed the One Big Beautiful Bill Act — will cut off incentives for Americans to install solar panels, purchase electric vehicles, or make energy efficiency improvements to their homes. It’s projected to raise household energy costs while increasing America’s carbon emissions by 190 million metric tons a year by 2030, according to the REPEAT Project at Princeton University.
The loss of these incentives will in part offset the continuation of tax cuts that largely benefit wealthy Americans. But the law as a whole won’t come close to paying for those cuts in their entirety. The legislation is expected to swell federal deficits by nearly $3.8 trillion over the next 10 years, according to the Tax Foundation, a nonpartisan think tank. This explosive deficit expansion could make it more difficult for the Federal Reserve to cut interest rates, possibly further constraining energy development.
President Trump has described the law as ending Democrats’ “green new scam,” and conservative lawmakers have celebrated the termination of Biden-era energy programs. The law is particularly devastating for programs encouraging electric vehicle sales, as well as wind and solar energy deployment.
But the act is more complicated than a simple repeal of Democrats’ 2022 Inflation Reduction Act. In one case, Trump’s big law ends a federal energy incentive that has been in place, in some form, since the 1990s. In others, Republicans have tied up existing energy incentives with new restrictions, regulations, and red tape.
Some parts of the IRA have even remained intact. GOP lawmakers opted to preserve Biden’s big expansion of incentives to support nuclear energy and advanced geothermal development. That said, the Trump administration could still gut these tax credits by making them effectively unusable through executive action.
It can be confusing to keep the One Big Beautiful Bill Act’s many changes to federal energy law in your head — even for experts. That’s why Heatmap News is excited to publish this new reference “cheat sheet”on the past, present, and future of federal energy tax credits, compiled by an all-star collection of analysts and researchers.
The summary takes each clean energy-related provision in the U.S. tax code and summarizes how (and whether) it existed in the 2000s and 2010s, how the Inflation Reduction Act changed it, and how the new OBBBA will change it again. It was compiled by Shane Londagin, a policy advisor at the think tank Third Way; Luke Bassett, a former Biden administration official and Senate Energy committee staffer; Avi Zevin, a former Biden official and a partner at the energy law firm Roselle LLP; and researchers at the REPEAT Project, an energy analysis group at Princeton University. (Note that I co-host the podcast Shift Key with Jesse Jenkins, who leads the REPEAT Project.)
