To manage the clean energy transition, it may have to get into the leveraged buyout game.

The United States produces more natural gas and crude oil than any other country ― it isn’t even a contest. But these “molecules of U.S. freedom” aren’t free: They’re extracted and transported through a network of rigs, drills, pumps, and pipes that are, increasingly, controlled and operated by myriad private equity companies. As a society, we have a strong interest in winding down these climate-polluting assets in a swift yet orderly fashion. But as businesses, their private equity owners don’t.
Over the past decade, pressure from shareholders and activists has succeeded in pushing many fossil fuel majors to consider how best to reduce their emissions. (Although that, too, has come at a cost.) But rather than winding down or cleaning up their most polluting and least profitable assets, many have instead simply divested. Coal companies in West Virginia have sold off their mines to undercapitalized vulture firms, which rely on continued coal sales to (in theory) pay for expensive environmental remediation costs. The same is happening in the oil and gas industry, where private equity firms have rolled up many of the drilling sites and pipelines, the capillaries and veins of the country’s energy infrastructure.
Shielded from the scrutiny of public markets, private equity funds have thus become some of the country’s top methane emitters by asset ownership in the natural gas sector. These opaque owners, capitalizing on other companies’ disinterest in holding high-emitting assets, are betting that fossil fuel infrastructure will keep paying out for quite some time; recent massive increases in expected energy demand have only juiced this trend toward industry consolidation.
Private equity firms and private debt funds, with their short-term profit horizons, concealed balance sheets, and seeming imperviousness to tighter financial regulation and shareholder activism, work well with fossil fuel assets, particularly those sold at fire-sale prices by publicly traded fossil fuel majors. Despite those assets’ long-term market value instability, their near-term cash flow prospects are what matter.
But what’s been good for fossil fuel majors’ balance sheets has been bad for the planet. Many of these buyout firms — well-capitalized private equity funds and scrappy vulture funds, alike — are not budgeting anywhere near enough for environmental remediation. One company, Diversified Energy Co, has been purchasing the rights to operate almost-depleted natural gas wellheads at scale, extending many of their lifespans by decades; far too few wellheads are closed each year to stem the methane spewing unimpeded into the atmosphere.
Rather than accept a situation where utilities and fossil fuel majors toss their liabilities to unaccountable vulture funds, sustainability-conscious investors and shareholder groups have begun screening transactions for responsible asset phaseout plans. But the lack of a binding set of transition standards has revealed a huge coordination problem: What counts as a responsible phaseout, particularly when private asset owners get to decide? The federal government has put down guidelines, but not its foot. A disorganized drawdown of assets under a patchy regulatory framework, without a doubt, leaves vulnerable communities on the hook for the financial, environmental, and health damages.
Progressive analysts have long argued that nationalizing fossil fuel assets and folding them into a state holding company is the best solution to sidestep this particular problem. The federal government is well staffed with energy and electricity experts who, operating under a public mandate to preserve grid reliability, can phase out fossil fuel assets on a unified, coherent timeline responsive to community needs while continuing to operate those assets as the “peaker” or “reserve” capacity required to ensure grid stability. A series of climate shocks has even convinced conservative leaders in Texas of the importance of public power for grid resilience, achieved through state ownership of “peaker” gas plants. This course of action is far worse than investments in, say, battery capacity ― California, for instance, is now reaping the benefits of massive battery deployment, which reduces the state’s need for gas ― but the logic behind building public reserve capacity is sound.
What advocates of a state holding company-type model do not often discuss is how exactly a government goes about acquiring all these soon-to-be-stranded fossil fuel assets. As just one example, a recent proposal from the Roosevelt Institute suggests that a state holding company should be “free to engage in debt financing, make equity investments, and acquire assets.” Sure, proposals like these are meant to buttress the case for why nationalization is a far better way to achieve a managed phaseout than surrendering that process to yield-seeking investors, not to detail the financial mechanics of a buyout. But still: this is vague!
Actually thinking through the specifics suggests that, interestingly enough, a comprehensive state-led buyout program could work a lot like an existing private equity transaction, for two key reasons.
Before we get there, we should separate private equity’s deserved reputation as an opaque asset owner from the way the industry works. Private equity’s calling card, the “leveraged buyout,” is little more than the act of raising debt to 1) purchase equity in and, therefore, ownership over an asset, and 2) refinance the asset’s liabilities. To do so, private equity funds work with banks or, more commonly these days, private debt or private credit funds, to raise debt that is generally backed by the combined assets of the purchaser firm and purchased asset.
But leveraged buyouts themselves are technically something that any financial institution could do. Take the federal government, the country’s most liquid debt issuer, whose debt anchors the global economy and backstops private financial institutions. It could raise debt (leverage) to finance a buyout of fossil fuel assets at interest rates far lower than private investors could. And because private credit funds, like other institutional investors, already buy loads of government bonds to match their liabilities and hedge their risks, this kind of nationwide leveraged buyout ― which would require substantial new debt issuance ― could actually help stabilize the financial system against potential shocks from within notoriously inscrutable private markets. The government can do exactly what private equity does, only a lot better, and with wider benefits.
The government has already planted the seeds of a leveraged buyout program across the country’s coal ash heaps. The Loan Programs Office, thanks to the Bipartisan Infrastructure Law and the Inflation Reduction Act, now offers far-below-market-rate loan guarantees to developers, including state governments and utility companies, seeking to repurpose fossil fuel assets through its Energy Infrastructure Reinvestment program. This program’s authority allows borrowers to use their financing for “refinancing outstanding indebtedness directly associated with eligible Energy Infrastructure.” All policymakers have to do now is scrap the program’s 2026 end date and, ideally, endow a federal institution with the power to borrow from this authority to purchase and refinance fossil fuel assets, rather than leave that task solely in the hands of state governments and utilities, with their varying capacities for and interest in coordinating a coherent phaseout plan. And now that interest rates are poised to fall, this refinancing becomes much cheaper.
That’s reason number one. Reason number two has to do with private equity funds’ ability to shield the assets in their portfolio from valuation volatility on publicly traded stock markets. Private equity funds need not publicize how much their portfolios are worth, except at infrequent intervals and when they sell assets. But thanks to private equity’s reputation as a high-return investment, fund investors pay a premium for the illiquidity of not always knowing the value of their assets. Purchase assets, juice returns, sell, and repeat ― this is the conventional private equity playbook.
But macroeconomic conditions today are such that private equity companies are now struggling to sell their portfolios. High interest rates have made leveraged buyouts of new assets and refinancing debts on unsold assets much more costly, and have tempered rapid asset value growth. As this once-frenetic industry slows down, funds are anxious to get assets off their books ― hence the recent wave of consolidation.
This is an opportune moment for the Feds to step in. It’s not just that the government’s capacity for undertaking leveraged buyouts is the greatest; more importantly, it never needs to sell. The valuation volatility that first prompts fossil fuel majors to divest from dying, dangerous assets yet incentivizes private equity funds to pump as much as they can out of them to resell them later at a profit is simply not something the federal government needs to worry about. A state holding company can siphon distressed assets off public markets and shut down the “merry-go-round” of asset sales and resales.
Objections to government intervention here are likely premised on the fact that, well, it’s the government. But the government would still be purchasing assets from private owners on financial markets, just like any market actor would. Today’s uncoordinated constellation of private fossil fuel firms and funds, on the other hand, cannot manage a coordinated phaseout, especially not under binding profitability constraints ― which the federal government does not share.
Local communities can’t finance phaseouts or cleanups themselves, and leaving hundreds of billions of dollars worth of stranded assets in the hands of under-regulated private firms will only accelerate climate catastrophe. The government must use the financial techniques that private equity funds have already pioneered to bring them to heel, in service of public goals.

Just look at Heatmap’s latest poll results.
A few times a year, Heatmap News surveys a few thousand Americans on the biggest questions driving the world of energy, environment, and climate change. We’ve spent the past few days writing up the results of our latest poll, which was in the field in late May and which I thought was particularly striking.
It’s worth taking a step back to look at the biggest results together, because the American view of data centers is essentially in free fall:
The upshot of these findings: The public‘s turn against artificial intelligence and AI infrastructure is real, widespread, and cross-partisan. It doesn't matter whether Americans started out tolerating data centers or having no opinion about them; they now seem to resent them en masse.

These results also suggest Americans see little distinction between data centers as energy users and data centers as the physical embodiment of AI and Big Tech. At Heatmap, we can be a wonky and energy-focused bunch, and so we tend to think about data centers primarily as large-scale electricity users. I think most approaches to come up with “data center policy” do the same. We know data centers are distinctive in some ways, of course — an AI data center might require more on-site batteries or power generation than, say, an EV factory — but fundamentally it is just another air polluter, large-scale power user, and light-industrial land user.
But the public does not see things this way. Americans understand data centers in the context of the much broader AI policy conversation about jobs, growth, alignment, and even human extinction. And so, I should add, do politicians: Senator Bernie Sanders has framed his data center moratorium proposal as a response to rapid AI development as much as anything having to do with energy affordability. For that reason, I wonder how long the distinction between these two policy conversations — data centers here, and AI policy over there — can persist.
One last thought on this topic: Is the public’s resentment starting to affect the AI boom overall? I think it might be. It was hard for me not to think of our polling results — or our analysis of canceled data center projects — as I read about a recent JPMorgan analysis that found America’s data center boom is “falling way behind schedule,” in the words of The Wall Street Journal. More than 60% of the data center capacity that is supposed to come online next year has yet to break ground, according to the bank; another 7% is “delayed.”
That’s partially due to equipment and labor shortages, but it also might be what a siting-and-permitting bottleneck would look like. Much like renewable developers or venture capitalists, data center developers work by picking a number of sites and trying to develop on all of them. If only a few sites work out, they’re still in the money. But if a falling share of projects are working out — if building anything, anywhere, is getting harder, everywhere — then it might materialize as delays.
Plus more of the week’s big money moves in critical minerals and electric vehicle charging.
Two of climate tech’s hottest sectors — fusion and critical minerals — dominated this week’s funding headlines. Helion led the pack with its $465 million Series G, helping to push the startup with the sector’s most aggressive commercialization timeline one step closer to putting power on the grid. The round follows last week’s news that German fusion startup Focused Energy secured a $240 million Series A, making it Europe’s most valuable fusion company.
Then there’s the critical minerals. Shortly after venture firm Gigascale Capital announced the close of its $250 million fund targeting the physical clean energy economy, it announced one of its first investments: Red Metals, a startup working to bring copper refining back to the U.S. Terra AI, which is using artificial intelligence to identify promising sites for mineral extraction, also landed fresh funding. Rounding out the week’s deals, EV charging and energy services company InCharge also raised a new round as it looks to expand into a broader suite of energy services.
Leading fusion startup Helion has nearly tripled its valuation with its latest $465 million Series G round, which aims to help the company deliver commercial fusion power this decade — the most ambitious timeline in the industry. Per the terms of the power purchase agreement Helion signed with Microsoft in 2023, the startup plans to turn on its first commercial reactor just two years from now. That’s far sooner than even its most precocious competitors, who aim to put fusion power on the grid by the 2030s at the earliest.
Joshua Kushner’s venture firm Thrive Capital led the round, which also included participation from new investors including Lux Capital and Alta Park Capital. Thrive now values the company at $15.5 billion.
“The investors that have joined this round, it’s institutional capital, some very marquee investors,” Helion’s CEO David Kirtley told me, explaining they were willing to back an unproven technology thanks to a series of recent milestones that Helion’s latest prototype reactor, Polaris, achieved. “Polaris earlier this year set records for temperature and fuel. We’ve also reduced a lot of the business risk on the regulatory front, the commercial front, and the actual supply chain, too.” In February, Polaris became the first reactor developed by a private fusion company to operate on deuterium-tritium fuel — the most common fuel in the industry — and to achieve a plasma temperature of 150 million degrees Celsius.
Helion differs from many of its peers pursuing more established reactor concepts such as tokamaks, stellarators, or laser-driven inertial confinement. Instead, Helion’s tech uses powerful magnets to collide and compress two fusion plasmas together, generating temperatures over 100 million degrees Celsius and triggering a fusion reaction. It then seeks to capture the electricity this reaction generates via electromagnetic induction — no steam turbine required — similar to the way regenerative braking works in an electric vehicle. If successful, the approach could enable smaller, more modular fusion reactors than conventional designs would.
While the company had originally aimed for Polaris to demonstrate electricity production from fusion in 2024, that date came and went with no new goal set. Kirtley told me that Helion remains on track to meet the terms of its agreement with Microsoft, however. The startup broke ground on its commercial reactor site last year in Malaga, Washington, where it already has access to a substation and grid interconnection from a dormant aluminum smelter. In addition to building out this facility, Helion also plans to use its new funding to boost production at its electrical component manufacturing plant in nearby Everett, which Kirtley said opened earlier this year.
As investors pour billions into artificial intelligence and the infrastructure supporting it, former Meta CTO Mike Schroepfer has raised an inaugural $250 million fund for his venture firm, Gigascale Capital, which is focused on the physical clean energy economy. This represents Gigascale’s first institutional fundraise since its founding in 2023; until now, the firm’s investments have come entirely out of Schroepfer’s own pocket.
The fund will target early-stage companies working in clean energy, grid infrastructure, critical minerals, and AI-enabled design and manufacturing, while reserving capital to continue backing its portfolio companies as they scale. Gigascale has already backed a number of big names in the space, including Commonwealth Fusion System, iron-air battery developer Form Energy, solid-state transformer company Heron Power, and clean baseload power startup Arbor Energy.
It’s also already begun investing out of this new fund, announcing this week that it led a $10 million seed round for critical minerals company Red Metals, which also included participation from JB Straubel, founder and CEO of the battery recycling company Redwood Materials. The company aims to help reshore copper refining in the U.S., and will use this fresh capital to support the development of a $70 million refining facility in Charleston, South Carolina. Red Metals says its process can convert copper scrap directly into a finished copper product, bypassing several of the costly and emissions-intensive intermediate steps typical of conventional refining.
The investment offers a window into the kinds of companies Schroepfer is most interested in — businesses that might lack the glamor of an AI startup but represent bipartisan opportunities to address core industrial bottlenecks. Copper, for example, is essential to all sorts of clean energy infrastructure, including transformers, power lines, and anode battery materials, but also critical for defense technologies such as radar systems and ammunition. Yet American copper production has been on the decline, with analysts projecting that the U.S. will face a refined copper shortage of over 2.5 million metric tons annually by 2035.
Sustainability-focused firm S2G Investments has been on a roll recently, announcing a $1 billion fund last month that aims to fill climate tech’s “missing middle” and backing Goshe Energy Storage with up to $40 million in strategic financing last week. Its latest move is leading a $46 million strategic investment round for InCharge Energy, an EV charging and distributed energy management company.
InCharge got its start installing and managing electric vehicle charging stations, and is now operating more than 30,000 assets across North America. Through its software platform and network of technicians, the company handles all monitoring, diagnostics, and on-the-ground repairs, taking on a charger’s full lifecycle to minimize downtime. With this new capital, InCharge plans to expand beyond EV charging and leverage its software and field service network in adjacent industries, including electrical infrastructure work such as panel upgrades and wiring repairs, as well as distributed energy resources like rooftop solar and battery storage systems.
“EV charging was the entry point, but our customers increasingly need help operating more complex energy infrastructure,” Rich Mohr, InCharge’s CEO said in a press release. “This investment from S2G accelerates our evolution into a full energy solutions provider and allows us to advance smarter technology and strengthen our service capabilities nationwide.”
It’s a hot week — nay a hot year, for critical minerals and subsurface exploration startups, especially for those pairing geology with artificial intelligence. AI-powered mineral exploration company KoBold Metals has raised about $1.2 billion to date, while geothermal exploration startup Zanskar has brought in about $220 million.
Now, another entrant is attracting investor attention. Terra AI has raised a $20 million Series A led by Khosla Ventures to help do it all — use AI to identify prospective sites for critical minerals mining, next-generation geothermal development, and permanent carbon sequestration.
Terra’s platform integrates vast geological and geophysical datasets to generate 3D subsurface models, as well as risk assessments that allow teams to evaluate a range of potential geologic scenarios. From there, the team can identify the best sites for exploratory drilling and thus reduce risk and uncertainty much sooner in the project’s lifecycle. The company even uses what it calls “geology reasoning agents” to help operators create their exploration plans, all with the goal of drastically reducing the notoriously long timeline between discovery and production, which can stretch to nearly two decades for many subsurface projects.
“Minerals sit at the center of every major technology and infrastructure transition, but today’s exploration results are not keeping pace with demand,” Terra’s CEO John Mern posted on LinkedIn. “Our mission is to advance the frontier of AI into the geosciences and help supply the metals and resources the next generation needs.”
One of the biggest fusion funding rounds of the year landed last week, and somehow much of the media — including me — missed it. German fusion startup Focused Energy raised a whopping $240 million Series A led by RWE, one of Germany’s largest energy companies. Yet unlike most deals of this magnitude, it arrived with little fanfare: No press release in my inbox nor a flood of headlines. So in the interest of making up for lost time, here are the details.
With this latest round, which also includes participation from the German Federal Agency for Breakthrough Innovation, the European Innovation Council Fund and Prime Movers Lab, Focused Energy has become Europe’s most valuable fusion company. Like several other leading players, including Inertia Enterprises and Pacific Fusion, Focused Energy relies on an approach known as inertial confinement fusion. This involves using powerful lasers to compress a tiny fuel target, creating the extreme pressures and temperatures required for a fusion reaction. To date, inertial confinement remains the only approach to have demonstrated net energy gain, with Lawrence Livermore National Lab achieving this milestone in 2022.
The startup plans to use this latest funding to build out a demonstration plant in the German state of Hesse, at a site where RWE formerly operated a nuclear fission plant. The company ultimately aims to build a commercial reactor by the mid-2030s.
Catching up with the American Council on Renewable Energy’s Ray Long.
Today’s chat is with Ray Long, CEO of the American Council on Renewable Energy. We first discussed the odds of permitting reform a year and a half ago, for one of the first Q&As in The Fight. Flash forward and we’re still in the same situation, but now also wrestling with added demand for electricity to power data centers. I wanted to talk again about whether he thought the rise of artificial intelligence would increase the odds of some federal deal happening any time soon. The result: a wide-reaching conversation about the future of the electric grid, the struggles to win community buy-in and the sclerotic nature of the U.S. Congress.
The following conversation was lightly edited for clarity.
Do you think the buildout of our energy grid is entwined with the rise of the nation’s data center buildout?
When you look at what we need over the next four years — 166 gigawatts, 15 times the peak load of New York City — that’s a lot of power to build. Roughly half of that is for data center and AI growth.
There are five things we can build in the next four years at scale to address that collective amount. First, it’s transmission — the transmission buildout will help to get a modern grid to enable power flow to where it’s needed in a much more effective way. That’s the first step because if we just build all that power, the current grid can’t handle it.
Second, there are four supply technologies that can be built: solar, batteries, wind, and natural gas. All four of those technologies, we know there’s enough equipment here in the U.S. available for purchase that we can build at volume. And I’ll say this — natural gas is only about 10% of all those gigawatts because of the availability of turbines from suppliers. You can’t get enough over the next four years. So when I talk about decarbonization, most of what is built to address this issue is zero-carbon resources, renewable energy resources.
If you were to compare the current conversation around data center development to the debate over developing renewable energy in the U.S. — or energy in general — do you see any similarities or differences?
There are always issues with permitting projects. Communities are always going to have concerns about what’s built in their backyards.
What’s new — and your polling shows this — is the level of concern communities have. But here’s the thing: Most of this can be overcome by developers going in, listening to what the needs of the communities are, then responding and through the permitting process addressing those concerns. You can’t do that 100% of the time. But my experience is, when you take that sort of approach, you can overcome a lot of it.
Most of the large data centers are actually doing the things I’m discussing — going in and saying, Look, we want to be grid interconnected because grid connection at the end of the day means the resources we’re bringing to bear are also going to make a stronger grid. Number two, it's investing in power generation sources like the ones I said — and those power sources will be on the grid, so they’ll solve for the increased power demands of a community.
Third, water. They should bring the water solutions. You’re seeing data centers coming in and saying it head on now, that they have closed-loop systems or whatever the solution is. At the end of the day, the communities they’re proposing these in have a real negotiating opportunity to make sure they’re holding the data center developers accountable to the needs of the community.
For a community to say we don’t want it here misses a real opportunity for those communities to get the power they need, the grid they need, and the ability to bring down energy costs.
How is the data center debate affecting permitting reform conversations in Washington, from your perspective?
Permitting reform in the U.S. at the state and federal level has been broken for years. The SunZia transmission project? It took 17 years to permit. Ribbon-cutting is in a week or two and there’s still litigation around it. From a business perspective, it’s just untenable, and it’s a miracle that the project is getting built. Developers need a chance to come in and have their project evaluated. Both the community and the developer should be able to get to a go or no-go in a couple of years on one of these projects.
How is data center growth affecting the permitting reform discussion? It’s a very hot issue right now. Right now I think in part because the data center issue is so huge — because we’ve only got four years to solve for the first really big tranche of power we need and prices across the board for electricity are escalating — this is coming to a head. The data center load is a part of the catalyst to get people talking about it [permitting reform].
Do you expect legislating in Congress on permitting reform this year? Anything beyond more conversation?
My hope is that we get a bill. A few weeks ago someone from the administration was quoted as saying they wanted a framework for a bill by the end of May, and it’s June now. We haven’t seen both sides or the administration coalesce around a final project yet.
We’re in a midterm election cycle. Typically it’s very difficult during these cycles to move bills like this. At the same time, with electricity prices increasing and the need to build more, to fix this, I’m very hopeful something will come together. And look at the Senate — you’ve got Republicans and the Democratic ranking members talking about this. It’s all good signs.
If everyone’s talking about energy and affordability during this election, isn’t that a good thing for action in the next Congress?
I’ll say this: You’re seeing the catalyst for it right now with prices rising, and almost every grid operator around the country has raised concerns about shortages at some point this year or next year. It’ll hopefully be enough to have policymakers do something about it this year.
