White House policy might not even be the biggest issue.

If you look at the polls, the presidential election — now exactly two weeks away — is very close. If you listen to the prognosticators, Trump has a slight edge. And if you look at the markets, whether prediction markets or Wall Street, Trump’s chances are looking pretty good, with a sweep of the White House and both houses of Congress now firmly on the table.
“Politics prediction market data have tilted toward a win by former President Trump, and markets have responded in line with this development,” Morgan Stanley analyst Michael Wilson wrote in a note to clients Monday. “Such an outcome should now be taken seriously,” wrote Jefferies global head of equity strategy Christopher Wood in a separate note last week.
And seriously is exactly how the market appears to be taking it, with a range of assets now seeming to be pricing in a Trump victory. Yields on Treasury bonds are also rising, which may be because traders see fewer interest rate cuts coming in a more inflationary Trump economy fueled by tax cuts, spending, and an icing of tariffs on top. Gold and Bitcoin prices have risen in the past month as well.
But what about the clean energy economy? Trump often speaks critically of the Inflation Reduction Act, clean energy in general, and wind energy in particular. With Republicans in control of Congress, those sentiments are more likely to be be turned into policy ... of some kind.
For investors in clean energy companies, Trump's improving odds make for nervous times. In the initial days after a Trump victory, as the reality solidifies, you’ll likely see some big price swings. Eight years ago, on Wednesday, November 9, 2016, an exchange traded fund that tracks around 100 clean energy stock called iShares Global Clean Energy, which is used as a benchmark for the industry as a whole, fell almost 5%, even as stocks overall jumped. In 2020, the fund rose more than 6.5% percent between close on election day and the following Monday, after networks had called the race for Joe Biden.
“I think stocks will trade on sentiment” following a win in either direction, Maheep Mandloi, an analyst at Mizuho, told me. “We’ll probably see that knee-jerk reaction.”
The iShares fund has been falling recently, dropping from $14.77 on September 27, when Kamala Harris peaked at 58.1% in Nate Silver’s polling models, to 47% on Monday, when Trump’s probability to win reached 52.7%.
“Renewables underperformed last week,” Mandloi wrote in a note to clients on Tuesday, with the iShares ETF down compared to the S&P 500 index. That sluggishness mostly came from solar stocks, particularly residential companies like Sunnova, Sunrun, Enphase, and Solaredge — “likely due to election, concerns” Mandloi added.
The fall has been even more dramatic for companies more exposed to Trump’s particular (dis)taste in energy, namely wind. U.S.-traded shares in Vestas, the Danish wind turbine manufacturer, have fallen over 16% since Harris peaked in the forecasts last month through Monday.
But a number of analysts are more sanguine about the fate of the IRA and the clean energy economy it has fostered. For one, the politics of repeal might not hold up in a Trumpified Washington. In August, 18 House Republicans in competitive districts wrote a letter to House Speaker Mike Johnson asking him not to target the clean energy tax credits at the core of the law. These same House Republicans have supported Johnson’s speakership where he’s taken flack from the body’s most conservative members, so this is hardly a constituency he can afford to ignore.
Even if a reconciliation bill passed next year were to scrap some or all of the IRA’s clean energy tax credits, the Internal Revenue Service could — as it has in the past when tax credits were about to expire — write rules that allow projects to claim the credits for years to come, Mandloi told me.
In any case, people in the tax credit market don’t seem to think the IRA tax credits are particularly at risk. “Political uncertainty has slowed the development of some industries,” analysts at LevelTen, a clean energy financial infrastructure company, wrote in a report last week. “It it hasn’t stopped the tax credit market from growing.” They assigned a low likelihood to a complete gutting of the IRA, noting that “there is bipartisan support for the investments catalyzed by the IRA across the nation.”
While it's possible that the bipartisan enthusiasm for investments stemming from the Inflation Reduction Act could protect much of the bill, the parts of the bill that directly support manufacturers may be the safest, namely the advanced manufacturing tax credit that has been especially popular in the solar industry.
These credits have been complemented by aggressive trade policy as well. Some of Trump’s earliest tariffs were on solar panels, and the Biden administration has also tried to protect the domestic solar manufacturing industry from “overproduction” in China and Southeast Asia. First Solar has thrown itself into domestic manufacturing with the wind of the Inflation Reduction Act’s manufacturing tax credits at its back. Bonuses for solar developers whose systems are made up of “domestic content” have helped, as well.
Morningstar analyst Brett Castelli wrote to investors a note last month acknowledging the risk to solar stocks from a change in White House party control. First Solar specifically, however, “would likely benefit from proposed trade policies, such as higher tariffs, under a Republican administration.”
The company’s stock is up 14% so far this year through Monday, although it has dipped as Harris has dipped in election forecast. The Invesco Solar ETF, which tracks the broad solar industry, is down 13% on the year.
“First Solar is unique in our view in the fact that it is relatively indifferent regardless of outcome,” Castelli told me this week. It’s helped by sheer size. “They have the largest U.S. presence for manufacturing solar panels here, domestically,” he said. “The biggest competitive threat to those factories would be cheap imports from China or Southeast Asia.”
But while the renewable energy industry is always at the risk of public policy shifts, for good and for ill, there’s another, harder to predict and harder to tame factor: interest rates.
Despite the spigot from Washington due to the IRA, many renewables companies have not been doing great in the stock market in recent years, and high interest rates are likely the reason why.
For renewables, most of the cost comes from simply building the thing. The “fuel,” whether it be photons or wind, is free. This means that renewables projects are highly sensitive to the price of the borrowed money they need for construction. While the Federal Reserve has finally begun to cut rates and anticipates continuing doing so through the end of next year, it’s by no means something it’s mandated to do, especially if there's a major change in fiscal policy going forward.
Predicting the path of interest rates is something people get paid far, far more than journalists’ salaries to do, and they’re often wrong. That being said, it’s not hard to see a world where a sizable Trump win keeps rates elevated.
As president, he showed zero appetite for fiscal restraint, and going into round two has indicated a desire for sizable tax cuts and almost nothing specific for any large scale cuts in spending, policy preferences that may be more likely to be indulged in a Washington under unified Republican control. “Interest Rates Will Be Higher in the Future, Especially if Trump Is President,” the Wall Street Journal declared earlier this month.
The “downside scenario” for stocks envisioned by Jonathan Golub, chief U.S. equity strategist at UBS investment bank, largely follows this scenario. “A combination of fiscal and monetary stimulus causes a reacceleration in inflation, forcing the Fed to abandon their rate cut plans,” he wrote to clients earlier this month. Clean energy could be hardest hit, no matter what happens to the IRA.

The singer’s music spanned genre and generating technology — and asked how to live in a world on fire.
This is an edition of Heatmap Daily, an evening review of the day’s news written by our executive editor. Sign up for it here.
Even as state-level Republicans have started talking about the data center boom more skeptically, the Trump administration keeps hugging it.
The Environmental Protection Agency will ditch a federal rule requiring states to publicize air pollution permits for major new industrial sites, including data centers and off-grid power plants, The New York Times reports. Those are some of the permits that we used in our recent reporting to, for instance, make sense of the scale of the coming gargantuan gas buildout. This policy might make sense as realpolitik in a more subdued development environment, but I don’t understand it when trust in any type of project is so low — and when even a majority of Republicans have turned on local data center development.
We badly need insight into the scale of artificial intelligence energy use right now, but this policy could make things even more uncertain. It reveals, too, just how much President Trump has fallen out of touch with the public.
I was planning on writing about a different topic today — and then Dolly Parton died. The country legend was 80 years old. Her nephew announced her death on social media in a sad, sweet, and lovely video.
What can I say? She was among the most admired living Americans. So voluminous and impressive was her legacy that I don’t even have to stretch much to find an energy or climate angle in it. How many other musicians were born in a home without heat or electricity — but would be eulogized upon their death by the public utility from their Tennessee Mountain Home?
Her music spanned genres and generating technologies. Some of our readers may appreciate her trio with Emmylou Harris and Linda Ronstadt of Neil Young’s environmentalist classic “After the Gold Rush”; others, her takes on lighting — or liquid combustion. But most will enjoy the lead single off her final album, where the studiously apolitical singer confronted the prospect of a burning world: “Now I ain’t one for speaking out much / But that don’t mean I don’t stay in touch,” she sang. “Liar, liar the world’s on fire / What we gonna do when it all burns down?”
In a fluke, the next tropical cyclone to form in the Atlantic basic will — according to the World Meteorological Organization’s 2026 list — be named Dolly. Let’s hope it puts on a show but doesn’t find any islands in its stream.
The New Mexico facility aims to achieve net energy gain by 2030.
Three-year old startup Pacific Fusion broke ground on Tuesday on what it says will be the world’s first fusion plant to produce more energy than it consumes. The company is aiming to achieve this milestone, known as net facility gain, by 2030. If successful, it would provide the first real-world demonstration that the physics underpinning commercial fusion can work at facility scale.
To date, fusion tests have only achieved scientific net gain — when a reaction produces more energy than was used to ignite it. But that metric ignores the substantial energy lost at other points in the system — whether that's converting stored power into a laser beam or electric current or sustaining powerful magnetic fields to hold the fusion plasma in place. For example, Lawrence Livermore National Lab first achieved scientific breakeven in 2022, and has since repeated the feat numerous times — something no other reactor has replicated. But its laser system, which compresses and heats tiny pellets of fusion fuel, is only about 1% efficient, meaning it draws orders of magnitude more energy from the grid than the reaction produces.
“They proved that with a big laser, if you drive fusion fuel to a certain pressure, you’re going to get more energy out of the fuel than went into the fuel,” Carrie von Muench, Pacific Fusion’s co-founder and COO told me. Indeed, the startup’s founding was partially inspired by the lab’s 2022 breakthrough, which proved fusion ignition is physically possible. “That’s awesome, but not a practical basis for commercial power if you have to store way more energy in the machine than you get into the fuel.”
Other fusion startups, such as Inertia Enterprises and Xcimer Energy, are pursuing the same technical approach as Lawrence Livermore — called inertial confinement fusion — while working to make the lasers dramatically more efficient. Pacific Fusion, however, thinks there’s a cheaper and more effective path, drawing inspiration from another national lab: Sandia.
Like Lawrence Livermore, Sandia National Laboratories built its fusion machine in large part to study nuclear weapons’ performance and impacts without live testing, helping scientists confirm that the country’s aging stockpile would still act as intended. But the Albuquerque, New Mexico-based lab uses a different approach, known as pulsed-power or Z-pinch fusion. It works by sending extremely fast bursts of electric current through a fusion target, generating a magnetic field that pinches and compresses the fuel and heats it enough to trigger a fusion reaction — all while using far less energy than a laser system.
In 2022, Sandia’s Z-machine achieved what was then the second-best fusion performance ever recorded, as measured by what’s known as Lawson’s triple product — the multiple of plasma density, temperature, and confinement time. That result inspired Pacific Fusion to base its reactor on Sandia’s system, scaling it up significantly, with the goal of delivering roughly two to three times more current than the lab’s machine. And while Sandia’s system is a singular, custom built piece of research equipment, Pacific Fusion plans to cut costs by housing its power system in 156 identical, mass-manufacturable modules that can be shipped, assembled, and swapped out for repairs.
The startup raised a whopping $1 billion Series A in 2024, which von Muench told me should be enough to cover the full cost of this demonstration facility, also located in Albuquerque. General Catalyst led the round, with participation from Breakthrough Energy Ventures, Stripe co-founder Patrick Collison, venture capitalist John Doerr, and others. Investors are doling out the funding in three sets of milestone-based tranches, two of which the company has already unlocked.
The first phase involved building the module’s key components and demonstrating that they met the required specifications, validating the company’s in-house simulation tools, and using those tools to show that its fusion targets could achieve ignition in the demo system. In the second phase, the team assembled and tested a scaled-down prototype module, which delivered 440 gigawatts of peak power. Next up is building a full-scale production module that will produce over a terawatt of peak power.
“Especially for these well-established approaches to fusion — like inertial fusion, which now has a proven path to scientific gain — the question is, how fast can we execute, and how cost-effectively can we execute successive first-of-a-kind projects?” von Mench told me. For Pacific Fusion, breaking ground on the demo reactor is a clear sign the company is on the right path, she told me. “Getting to this milestone was the first real test of our team’s ability to do that.”
The company says it’s unlocked each funding tranche ahead of schedule, and has now gone from founding to groundbreaking in less than three years. It’s betting that cheaper hardware — that is, swapping expensive lasers for electrical switches and capacitors — combined with mass manufacturable components and a supply chain that avoids rare and expensive materials, will also give it an edge in the race to commercial fusion.
Once it completes the demo reactor, the company will begin work on its first commercial power plant, which von Muench told me should come online by the mid-2030s. But in the meantime, this first reactor could provide a nearer-term revenue stream by helping the Department of Energy’s National Nuclear Security Administration conduct stockpile stewardship research. Pacific Fusion just signed a non-binding memorandum of understanding with the NNSA that opens the door for the agency to use the startup’s machine for national security purposes.
Pacific Fusion’s tech is uniquely suited for such high-stakes testing. That’s because the company’s process, once scaled up, is designed to produce bursts of fusion energy exceeding 100 megajoules — roughly enough to power over 40 houses for an hour, but released in just a fraction of a second. That’s much more energy than either fusion system at Lawrence Livermore or Sandia produces, and would make Pacific Fusion’s demo plant the world’s first "high-yield" facility, capable of recreating the kind of extreme pressure, heat, and neutron conditions produced by a nuclear detonation. The resulting data could then help the government assess how warheads and other components hold up as they age.
Von Muench views this potential government work as a valuable side benefit of the company’s overall approach, rather than a primary or necessary source of revenue. “But nevertheless, building a diversified and valuable business along the way, I think certainly improves the probability of success and the speed with which you can deliver against the fusion power goal,” she told me.
And for those that still doubt that next decade, we’ll actually see real fusion reactors coming online? “I would just say wait and see,” she told me. “We’re building.
Current conditions: A sleepy Atlantic hurricane season just snapped to attention as two tropical storms started forming near the Caribbean and off Africa’s coast • Southern California is bracing for a week of triple-digit temperatures • The Hawk Fire has forced 42,000 people to evacuate an area near Reno, Nevada.

The United States nearly doubled its pipeline of gas-fired power plant projects in the first half of this year, “but uncertainty persists about how and when this capacity gets built,” the watchdog Global Energy Monitor concluded in a new analysis. The country now has 189 gigawatts of planned gas projects, accounting for one-third of the global total. Completing all the plants would cost more than $647 billion. The U.S. is taking unique approaches to expanding its gas fleet, including building what would be the largest power station in the country as a federally-owned gas plant. As my colleague Emily Pontecorvo points out, however, there’s a big asterisk on these numbers: Many of the projects are still in nascent stages of development and may never be built. “When I went through the group’s data to try to identify the 10 biggest gas projects under development that are tied to data centers, it became clear how slippery the whole picture really is,” she says in her write-up of the report, which I highly recommend checking out.
Electric cooperatives, meanwhile, are lobbying to make building more gas plants even easier. Last week, Utility Dive reported, the National Rural Electric Cooperative Association urged the Environmental Protection Agency to exempt more gas plants from emissions rules.
Last month, a report by the Massachusetts Institute of Technology’s Center for Energy and Environmental Policy Research made the case that “the glass is half full” on federal green spending, finding that President Donald Trump’s landmark tax law, the One Big Beautiful Bill Act, preserved 74% of the clean energy gains from the Biden-era Inflation Reduction Act. (You should listen to my colleague Robinson Meyer’s podcast conversation with the author, Lily Bermel, from last month.) Now the Natural Resources Defense Council has come out with the bearish counterargument. The environmental group’s new analysis, out this morning, found that the U.S. will lose between 390 gigawatts and 540 gigawatts of new solar, wind, and battery projects that would have been built before OBBBA’s passage.
“I see a glass much more than half empty,” Amanda Levin, the director of policy analysis at the NRDC, wrote in an op-ed for Heatmap. “The repeal of the key IRA tax credits and other Trump administration policies will result in 637 fewer gigawatts in added clean energy over the next 15 years and cost the average American household $4,500.”
One popular theory of Trump’s motivation for joining Israel in launching a war against Iran is that halting the flow of oil through the Strait of Hormuz would demonstrate China’s vulnerability as a top importer of foreign fossil fuels and America’s strength as the world’s No. 1 producer of oil and natural gas. But China’s actual response proved to be robust. In addition to ramping up domestic production of its own limited reserves of fossil fuels, Beijing deployed more renewables and nuclear reactors, electrified things that once ran on oil or gas, and made real progress on fuels such as hydrogen and its derivatives. Between that and China’s own carbon-cutting goals, last year was likely the peak of the country’s demand for oil, according to the state oil company Sinopec. In an earnings call Monday in Hong Kong, Sinopec Chairman Hou Qijun said demand had already crested, two years earlier than the 2027 peak the company had previously forecast, according to Bloomberg. Keep in mind that only means oil demand is no longer growing. The Chinese economy isn’t exactly on a GLP-1 treatment for crude just yet. In fact, Reuters noted that, on the call, Sinopec said it was now eyeing Brazil and Africa as new sources of oil imports. That’s probably partly why, as I told you last week, American oil giants are setting sights on Africa.
In the meantime, the People’s Republic may finally be sorting out carbon capture and storage. Last week, GD Power’s Jinjie Company issued a tender for engineering design of its 4 million tons per year full-sized CCS project for coal power stations. The project, according to the China Hydrogen Bullet, “is described as the world’s first full-flue-gas carbon capture facility at a coal-fired power plant.”

Nearly two weeks after a powerful storm took out power for roughly 800,000 households in one of America’s most important industrial clusters, as many as 30,000 in northwest Indiana remained without electricity this past weekend. “My people are being overlooked,” Myles Tolliver, a Gary councilman whose family decamped to Chicago while the power was out, told The New York Times. “Our families are sitting in the dark. We don’t need any more excuses. We need the lights on.” By Monday evening, more than 8,300 households and businesses remained disconnected from the grid, according to data on PowerOutage.us, a tracker website.
The worst outage in the U.S. as of Monday night was in Shelby County, in the southwesternmost corner of Tennessee, where storms knocked out the power for nearly 32,000 households and businesses. Behind that was Washoe County, on the western flank of Nevada, where the aforementioned Hawk Fire damaged power lines.
The Trump administration is working with the British startup Core Power to help build a fleet of nuclear-powered merchant vessels to loosen China’s tightening grip over commercial shipbuilding. In an interview Monday with the Financial Times, U.S. Maritime Administration chief Stephen Carmel announced a public-private partnership agreement with Core Power in a bid to speed up commercialization of nuclear propulsion for ships. “We are not going to beat China by being a cheaper version of China. They have mastered the art of being cheap,” Carmel said. “The way we win in all this is to change the terms of the competition to something that is more favourable to us. So, we don’t compete on trying to be cheap. We compete on technology … and nuclear technology is something we are really good at.”
Vietnam just took a big step toward building its nuclear power station. On Monday, NucNet reported that the fast-growing Southeast Asian nation’s parliament had approved plans for its first commercial nuclear plant, a two-reactor, 2.4-gigawatt plant built by Russia. Hanoi is looking beyond just atomic energy to supplement its surging demand for power. The municipal government in Ho Chi Minh City, the nation’s largest metropolis, is reviewing a feasibility study into developing up to 6 gigawatts of offshore wind, according to offshoreWIND.biz.
The Trump administration fast-tracked a Rare Earth Resources’ plan for an open-pit mine in Wyoming to extract rare earth minerals. Even in a deep-red state that mines more coal than any other in the U.S., the project is getting pushback. “It was kind of hush-hush, in my opinion, as far as not much word about it around Sundance,” Sundance resident Justin Johnson told WyoFile. “All of a sudden, in July when it came to our attention, it’s like, ‘Holy cow. We got little time before the federal deadline to get our comments and concerns to the Forest Service … You would think there’d be a lot more time for the actual owners of public land — the citizens of the U.S. — to have a response to what’s going on.”
