On the third anniversary of the signing of the Inflation Reduction Act, Heatmap contributor Advait Arun mourns what’s been lost — but more importantly, charts a path toward what comes next.

Today, the Inflation Reduction Act would have turned three years old — if it hadn’t been buried alive in a big, beautiful grave. While the IRA was a hodgepodge of programs salvaged from President Biden’s far more ambitious Build Back Better agenda, it still represented the biggest climate investment in U.S. history. It catalyzed over $360 billion in energy and manufacturing investments and was expected to drive the installation of over 155 gigawatts of new solar and wind energy by 2030. And now Republicans have taken a sledgehammer to its achievements.
The timing could not be worse — not just for the climate, but also for the energy systems that we rely on. At a moment when the energy sector requires $1.4 trillion worth of upgrades by 2030 just to keep up with rising energy demand and increasingly erratic weather, Republicans have instead delivered a one-two punch of tariffs and tax hikes, sabotaging the industrial base required to deliver those investments and raising the retirement age of our power generation fleet.
All over the country (Texas and California maybe exempted), our aging electricity system is putting in its two-weeks notice. Staring down the barrel of precipitous demand growth, the country’s regulated utilities have requested over $29 billion in rate increases, concentrated across the West and South. The Department of Energy ordered the delayed retirement of coal plants and oil generators to manage this summer’s demand peaks. Meanwhile, capacity market prices on two of the country’s largest grids, PJM and MISO, have reached record highs ― a cry for new supply that is now increasingly unlikely to materialize quickly or cheaply. Two months ago, an unplanned nuclear reactor outage on a congested part of Louisiana’s energy grid led to a blackout for 100,000 people in and around New Orleans. That meant no working AC or refrigerators across large swaths of the city during a sweltering Memorial Day weekend.
All of this amounts to an opening for Democrats to shift public opinion decisively in favor of renewed climate action. Moving forward, lawmakers cannot ignore our infirm fossil-fired energy system, which stands to thwart their ability to deliver affordability, employment, health, and resilience to their constituents. Despite our recent losses, we still need an energy policy ― a climate policy.
What should the Democrats’ second attempt at a clean investment program look like? Having delivered the Bipartisan Infrastructure Law and the Inflation Reduction Act, laws that committed the state to the realization of a particular energy future, Democrats are well-positioned to build on their successes, and even to engage Republicans who remain interested in supporting innovative technologies, decarbonizing industry, and protecting public lands.
Where they cannot meet Republicans halfway, Democrats should double their ambitions. They must continue to embrace the power of federal investment to shape markets and achieve policy goals. But they must also learn from the shortcomings of their previous legislative outings and substantively change how the federal government invests in the first place. The way forward for Democrats starts with mapping out exactly how far they didn’t go, and ends with going there.
IRA and BIL were paradigm-shifting attempts at market-shaping. They laid the groundwork for the deployment of promising clean firm energy technologies such as next-generation geothermal and nuclear energy, as well as for necessary grid and supply chain upgrades, such as long-distance transmission corridors and critical minerals processing.
IRA and BIL were not, however, a comprehensive climate policy. They created cost-share programs for infrastructure resilience but neglected to buttress municipal bond markets, which states and local governments can use to make longer-term investments in climate resilience and adaptation. They penalized methane emissions but organized no comprehensive or compulsory managed phaseout of fossil fuel infrastructure. They failed to advance or adequately finance a coordinated deployment strategy for any key energy sector. And they shed the transformative vision of Biden’s Build Back Better agenda, which sought to stabilize the cost of living for Americans in the meantime — a tactical retreat that, in retrospect, looks ill-advised given voters’ current worries about affordability.
I am aware that criticizing BIL and IRA on these grounds amounts to judging them for goals they didn’t attempt to achieve. Judging them by the goals they did attempt to achieve, however, reveals that they only ever worked incompletely. Taken together, BIL and IRA expanded the energy tax credit system, created powerful programs for piloting and deploying innovative energy technologies, and seeded an ecosystem of regional financing institutions devoted to more equitably distributing the benefits of decarbonization. But the energy tax credits were never expansive enough; the programs intended to motivate investments into deeper decarbonization were not flexible enough to drive the mass uptake of emerging technologies; and efforts to decarbonize disadvantaged communities lacked a coherent strategy and ran headlong into local capacity constraints.
Speeding up the energy transition and building new infrastructure at scale requires endowing federal and state agencies with adequate appropriations, access to liquidity, and crystal-clear, wide-ranging mandates, as well as empowering them in statute with considerable flexibility as to the financial products and strategies they deploy to achieve those mandates.
Although imperfect, the IRA’s tax credits scored some significant wins that should undoubtedly inform future policy. The law took an existing system of technology-specific subsidies that had been on the books in some form since 1978 and made them technology-neutral, allowing developers of nearly any zero-emissions energy technology to access tax relief. It expanded the credits to domestic manufacturers of certain low- and zero-carbon technologies. It created a tax credit transfer market, allowing developers with limited tax liability to sell their credits for cash on an open market to any tax-liable buyer, rather than engage in expensive and complex “tax equity” transactions with a few large banks. It made certain credits directly accessible to tax-exempt entities, significantly broadening the pool of potential users. And most of these credits remained entirely uncapped ― a “bottomless mimosa” for developers that spurred over $321 billion in clean energy and manufacturing investments and supported more than 2,000 new facilities across the country.
To be sure, the IRA did not level the playing field perfectly across developers or across technologies. Developers of energy transmission, grid transformers, and electric rail were shut out of the credits. Tax-exempt public and nonprofit developers ― entities as large as the New York Power Authority and as small as local churches ― could not monetize depreciation or participate in the transfer market. And some credits remained capped, forcing developers to apply and cross their fingers. But as early as 2023, Goldman Sachs argued that even with these inadequacies ― which have easy legislative and statutory fixes ― the IRA would still have spurred over $3 trillion in investment by 2033.
The GOP has gutted much of this system, shortcomings and all, and replaced it with a tangle of red tape. The energy tax credits are once again technology-specific ― solar and wind developers have a few months left to start a project and claim the credits as written, though what it means to start a project got more complex just yesterday. But even the “clean firm” energy technologies that can still claim credits until 2032, such as nuclear and geothermal, may not be safe under new “foreign entity of concern” rules, which condition credits on developers’ ability to limit their reliance on Chinese suppliers and investment, requiring them to map out their supply chains at an unprecedented level of detail.
Democrats seeking to restore and build upon this plank of the IRA have their work cut out for them. The developers and manufacturers of any technology that contributes to zero-emissions energy production should be able to access and monetize federal support regardless of their tax status and free from the rigmarole and uncertainties imposed by competitive application procedures. Goldman Sachs’ $3 trillion estimate is now the lower bound of what’s possible — for instance, a tax credit for transmission investments suggested as part of Build Back Better but excluded from the IRA could have catalyzed over $15 billion in investment and supported the economics of all other energy projects. To the degree that the tax credits can help build industrial capacity and institutional support for decarbonization, future policymaking should maximize their remit and their distribution.
Tax credits alone, however, are hardly a skeleton key to decarbonization. Being disbursed only once a project is complete, tax credits do not substitute for the kinds of upfront financial support that project developers — especially developers of emerging technologies — require to complete their projects in the first place. Private investors have been comfortable with solar, batteries, and onshore wind because these projects can be completed, claim their tax credits, and earn revenues on the grid on a mostly predictable timetable. But new nuclear reactors, geothermal, hydrogen, green steel, and carbon capture are unfamiliar investments, have uncertain development pathways and return profiles, and thus remain un-bankable to investors.
This is why BIL and IRA created powerful programs worth tens of billions of dollars to finance the deployment of emerging clean technologies and break this vicious cycle of uncertainty. The Office of Clean Energy Demonstrations, or OCED, and the Loan Programs Office, or LPO, in particular, were empowered to support, at scale, the testing and commercialization of these emerging technologies as well as conversions of whole electricity grids.
OCED, with over $27 billion in appropriations, set up hubs for hydrogen and carbon capture projects across the country, and funded a suite of advanced steel and iron decarbonization projects. Endowed by BIL and IRA with over $15 billion in total credit subsidy and well over $300 billion in total loan authority, LPO made ambitious investments across a host of innovative technology categories, including ― but certainly not limited to ― energy storage, sustainable aviation fuels, virtual power plants, EV charging, and bioenergy. At the end of 2024, the LPO had over 200 loan applicants in its queue.
By rescinding OCED’s unobligated funding, ambiguously rewriting LPO’s lending authorities (while rescinding most of its unobligated credit subsidy), and pulling the plug on billions of dollars worth of conditional commitments, the GOP has stopped years of progress in its tracks. In the meantime, LPO has shed considerable staff while the administration has prevented it from making any new commitments. The combination of the “foreign entity of concern” rules constraining tax credit eligibility and this shuttering of federal financing opportunities could seriously throttle the development and commercialization of nuclear energy in particular, the darling du jour of Republicans’ energy strategy.
If these offices were once the engines of decarbonization, they needed a stronger spark plug. The LPO, in particular, has a special authority to finance state government-backed, non-innovative clean energy projects, such as regional battery manufacturing clusters or a state power developer’s renewables portfolio, but has never used it. And while OCED and LPO can provide developers with some degree of upfront support, LPO cannot easily provide construction loans, cannot derisk project cash flows to provide security to investors, and cannot mandate offtake. These deficiencies prevent ambitious borrowers with unproven technologies from scaling up: they scare off private lenders in the infrastructure sector, many of which are skittish about construction risk, require project developers to demonstrate three to five years of stable cash flows, have a low tolerance for market price uncertainty, and have shareholders who demand a certain level of returns.
The DOE can bridge this “valley of death” by using its broader market-shaping authorities to take a more aggressive “dealership” role in these sectors, providing stable offtake for developers through upfront purchasing while becoming a reliable source of supply to downstream customers (like an actual car dealership or a grocery store). The DOE has in fact already used this approach to provide demand-side support to its now-endangered hydrogen hubs through OCED.
These kinds of public dealership arrangements are not unique or path-breaking: The Federal Reserve’s backstop of the municipal bond market in 2020, nonprofit investor Climate United’s planned EV trucking purchase-and-lease program in California, and even the Department of Defense’s recent MP Materials deal are all examples of public entities addressing a mismatch in the supply of and demand for a critical good and, in doing so, shaping markets toward public ends.
For all that BIL and IRA built avenues for developing and deploying energy technologies, they were also full of programs aimed at distributing the fruits of decarbonization equitably. Both the energy community bonus credits, a provision in the IRA that increased the value of the energy tax credits for projects in poorer, higher-unemployment, and energy facility-adjacent communities, and President Biden’s Justice40 initiative, which directed 40% of federal spending toward poorer and more rural communities, exemplified the administration’s “place-based” approach to industrial policy and economic development. The Biden administration heavily encouraged disadvantaged communities, local governments, schools, nonprofits, and tribal nations to develop their own clean energy projects — aided by the IRA’s direct pay mechanism, which allowed tax-exempt entities to access subsidies — by drawing on the various local decarbonization programs in BIL and IRA.
The Greenhouse Gas Reduction Fund, perhaps the most important of these programs, exemplifies the promises and pitfalls of the administration’s approach to “place-based” industrial policy. Managed by the Environmental Protection Agency, GGRF provided $27 billion to disadvantaged communities for the financing of rooftop solar, zero-emissions transport, and net-zero housing. That pot was split into three thematic buckets ― $7 billion to the Solar for All program, specifically for rooftop solar development; $14 billion to the National Clean Investment Fund, for supporting clean energy project finance more broadly in disadvantaged communities; and $6 billion more to local and regional technical assistance providers. Each program then subdivided its appropriations further. Solar for All went to 60 recipients across the country via a competitive application. The National Clean Investment Fund’s $14 billion was split among three awardees, each a coalition of various financial institutions designed to lend to energy projects, such as green banks, impact investors, and nonprofits ― and each of those recipient coalitions planned to subdivide much of its funds still further, first among coalition partners and then to subordinate local and state partners.
That dizzying program structure was meant to endow local communities with the ability to finance their own projects. And by including so many nonprofit institutions, GGRF could make significant inroads into Republican states, whose officials might otherwise reject federal funding.
But there was not much coordination between partners and subawardees around how best to deploy those funds. And what seemed like a firehose of financing often reached local recipients as a trickle of pre-development and technical assistance grants. Demanding that local organizations build their own capacity to plan, finance, and develop projects (or hire expensive external consultants to do so) ― with limited and one-time funds, no less ― is duplicative and inefficient, and it defeats GGRF’s own stated goal of mobilizing private capital through building standardized markets for decarbonization, thereby slowing down the pace of emissions reductions. The program’s complexity also left it vulnerable to EPA Administrator Lee Zeldin’s efforts to hound the program in court and freeze its funding.
Pandemic-era proposals for a National Investment Authority, as well as legislative proposals for a national green bank ― predecessors to the GGRF ― differ sharply from this status quo, instead highlighting how public finance can benefit from economies of scale. Larger financial institutions tasked with deploying clean energy projects can more easily prepare portfolios of projects for co-investors, engage with utilities, raise debt on municipal bond markets, and build a bench of trustworthy private developers to contract for projects. If they are publicly administered, these institutions can also take more risk, undercut private lenders, support more developers, engage with local communities to meet their needs, and use revenues from higher-return projects to derisk lower-return projects that might be necessary to build to achieve their resilience and affordability goals.
Should policymakers get a second shot at building a national green bank system, they should not try to recreate GGRF’s fractal approach to energy finance. Rather, policymakers must ensure that financing sits in the hands of public agencies that already have the authorities and expert staff to be ambitious market-shapers: bond banks, state-led energy finance authorities, and public developers. The good news is that state-level green banks empowered with state funding and a political mandate are already exercising their capacities to shape markets and support disadvantaged communities directly: the New York Power Authority, the Minnesota Climate Innovation Finance Authority, the Connecticut Green Bank, and the Greater Arizona Development Authority, to name a few, are all taking it upon themselves to raise debt and contract with developers to undertake ambitious energy and infrastructure investment programs.
But Democrats should be clear-eyed about the consequences of this reorientation: It means rejecting the prevailing wisdom that local nonprofits should necessarily coordinate local project development. Local groups can be extremely effective advocates for communities’ needs ― but in contrast to public investment agencies, their capacity to finance and implement solutions is simply not great enough.
This analysis of IRA and BIL leaves out more parts of the laws than it includes ― to take just one example, the BIL’s $5 billion National Electric Vehicle Infrastructure charging station program. But the story is similar: Ambitious as it seemed, NEVI money could only flow when state governments set up implementation offices and had their spending plans approved by federal officials. Most states, which had not prepared for any of this, took years to build the requisite capacity ― just in time for the Trump administration to try and snatch away the funding (though it recently admitted defeat in that project). In fairness to state governments, the EV charging sector is incredibly new. But even this program highlights how IRA and BIL lacked the capacity to be implemented as quickly and efficiently as their supporters hoped.
Going above and beyond BIL and IRA to deliver an energy policy that stabilizes Americans’ cost of living while driving an energy transition away from fossil fuels and toward the technologies of the future ― Democrats should embrace this challenge. But they should also be aware that climate ambition runs headlong into the same institutional problems facing American democracy at large. The Senate filibuster prevents either party from comprehensively redesigning the federal government, its institutions, and its regulations to serve Americans more quickly and more efficiently. That leaves both parties reliant on budget reconciliation ― to our detriment. The head-spinning design of GGRF was itself an artifact of the reconciliation process, which prevented Congress from creating a single green bank institution or giving it a specific mandate; its awardee organizations and coalitions certainly did not ask for the program structure they got.
There’s a lot more that budget reconciliation will never solve: the century-old American utility system, the regulatory thicket of U.S. electricity markets, or the land use and permitting rules that constrain project development and grid interconnection. And things could get worse: Trump-appointed judges and Supreme Court justices who reject federal agencies’ and state governments’ attempts to regulate fossil fuel infrastructure have placed the legal system itself at odds with responsible energy system management. The courts may no longer be able to block clawbacks and recissions of legally obligated federal spending. Democrats, like clean energy developers, do not fight on a level playing field.
While Democrats are out of federal power, they should practice ambitious climate policymaking at the state level. States already have considerable ability to raise finance and build capacity for ambitious infrastructure projects ― and they might have to quickly, considering the drain of federal capacity that might support them. By developing their own public programs for transmission finance, utility-scale battery procurement, virtual power plants, and clean firm energy pilots, Democratic state governments can ensure that the ecosystem of clean energy developers created by BIL and IRA does not disappear for lack of demand — and in doing so, these states would help stabilize the cost of clean energy project development.
Finally, Democrats should not forget that climate remains a cost of living issue. In a city like New Orleans, rocked by the recent nuclear outage, residents spend, on average, over 19% of their incomes on their energy bills, over three times the DOE’s threshold to be considered an energy-burdened community. Their bills already include adders for climate adaptation and disaster preparedness ― yet, for all they spend, they still face blackouts, and their costs will only increase as their grid continues to deteriorate. Here, climate policy is not about combating Chinese supply chain dominance, or even about delivering an American industrial renaissance. It’s about keeping the lights on, keeping bills low, keeping the air clean, and keeping residents safe from disaster.
It turns out that voters all over the country still care about these goals. A majority of likely voters in the next election think climate change will have a direct impact on their or their family’s finances. This constituency is still in play — and given sharply deteriorating macroeconomic conditions, soon-to-spike electricity prices, and the ever-increasing threat of climate disaster, these cost-of-living-focused voters could be far more vocal, relevant, and hungry for change than a coalition built on vague sabre-rattling against China.
In 2022, Democrats made a valiant first attempt to transform the state itself. Perhaps it was inadequate, perhaps it was impossible to do more at the time, but that’s no reason not to think seriously about the kind of policymaking, institutional, and financial interventions that would be called for should they get a second shot at realizing that goal. The rollback of the IRA only reveals how much Democrats left on the table three years ago ― and how much farther a real climate policy could go.
Editor’s note: This story has been updated to clarify the relationship between the unplanned nuclear shutdown and the power outage in New Orleans.

The seed-stage startup is eyeing a Series A after successfully enriching lithium and hydrogen isotopes.
While most coverage of the buzzy fusion energy industry — including my own — tends to focus on the startups promising to build commercial reactors within the next decade, a whole host of supporting industries will also need to mature in order to make that long-held scientific dream a reality. Isotope production is one of the biggest. No matter a company’s technical approach to fusion, it likely demands hydrogen and lithium isotopes — the former to fuel reactors, and the latter to breed more of that fuel.
That’s where Marathon Fusion comes in. The San Francisco-based seed-stage startup is developing isotope separation technology for two key purposes: recycling tritium — an extremely rare hydrogen isotope — from reactor exhaust so it can be reused as fusion fuel, and enriching lithium-6, which is needed to breed new tritium. On Thursday, the company announced that it succeeded in using its plasma centrifuge technology to enrich lithium-6 and hydrogen isotopes in the lab. (It can’t yet test the tech on actual tritium, which is expensive, radioactive, and tightly regulated by the Nuclear Regulatory Commission, so Marathon is validating its separation physics using the non-radioactive proxies deuterium and protium.) Marathon now plans to raise a Series A based on the results.
“People have wondered for a very long time when fusion is going to come, and everyone’s waiting on the big scientific announcements,” Marathon’s CEO Kyle Schiller told me. But while the industry waits for those breakthroughs, he argued, it’s high time to start commercializing the infrastructure fusion will need to become an actual commercial industry. “Ultimately, what we’re doing is reactor agnostic. Everyone’s going to need it.”
In the near term at least, most fusion companies plan to use deuterium-tritium plasmas to power the fusion reaction. But the process is inherently inefficient — only a small fraction of the fuel actually fuses in the reaction, while the rest gets expelled, even though it still contains valuable, unburned tritium that can be captured and reused.
Today, neither tritium nor the lithium-6 needed to make more of it are produced at anything close to the scale even a single commercial fusion reactor would require to get up and running. And existing isotope separation technologies — largely designed for small-volume defense programs and experimental reactors — aren’t sufficient to bridge the gap.
“When you have a single fusion power plant, that’s going to need about 1,000 times more lithium than anyone is producing today in any country,” Schiller told me, referring to lithium-6. “It would be totally prohibitive to build a fusion power plant at those economics.”
And while it’s at least possible to produce enough of this isotope to supply a future fusion industry by enriching lithium mined from rock, tritium presents a more fundamental problem. Because it’s radioactive and decays relatively quickly, it doesn’t occur naturally in meaningful quantities. Today it’s produced commercially as a byproduct of some fission reactors, but that supply amounts to just a few kilograms per year. A single 1-gigawatt commercial fusion reactor, by contrast, would need an estimated 56 kilograms annually. Meeting that demand will require fusion companies to breed their own tritium inside the reactor, a process that involves fusion-generated neutrons hitting lithium-6 nuclei, splitting them into tritium and helium.
It will also necessitate recycling the substantial amount of tritium that passes through the reactor without burning up. That’s where Marathon’s plasma centrifuge comes in. Centrifuges themselves are nothing new — engineers have used them for decades to separate uranium isotopes for nuclear fuel, spinning the gas at such high speeds that isotopes with different masses separate. Plasma centrifuges work on the same principle and have been studied since the Manhattan Project, but no one has yet successfully commercialized the approach for lithium and hydrogen.
Part of the reason is that, until recently, there simply wasn’t much demand for these isotopes. But the raw materials also present a physics challenge: Lithium and hydrogen isotopes have very similar masses. Separating them thus requires spinning the plasma so rapidly that, historically, the resulting heat has undermined the separation process itself. To address this, Marathon’s proprietary centrifuge tech uses a “partially ionized” plasma, in which some atoms have been stripped of their electrons while others remain neutral. The company says this configuration allows the centrifuge to operate at lower temperatures.
The materials testing lab Covalent has certified Marathon’s lithium-6 enrichment. The company hasn’t had its hydrogen separation results independently verified, though an MIT nuclear engineering professor has reviewed the device’s design. As a participant in ARPA-E’s Vision OPEN program, which solicits and supports ambitious energy projects, Marathon has also presented its hydrogen separation methodology and results at the ARPA-E fusion programs meeting in June.
Now, Schiller told me, the challenge is scaling up the technology’s core systems. “We need bigger magnets, better cooling, bigger power systems, and so that’s a buildout that’s going to take time and more capital,” he said. “But as far as the science is concerned, we feel like it’s at the point where we’re ready to make those kinds of commitments.”
Marathon is now looking to raise capital to build its first commercial pilot facility, with the goal of reaching full-scale production by 2029. Schiller told me the company expects its first full-scale facility to produce tens of tons of lithium-6 per year — enough, he says, to fuel a new gigawatt-scale fusion plant roughly every two years. Marathon also plans to recover and repurpose about 560 kilograms of tritium annually — roughly the amount that cycles through a 1-gigawatt reactor’s fuel system each year, most of which exits in the reactor’s exhaust without ever fusing.
Once fusion reactors are operating at scale, Marathon has a few other tricks up its sleeve. The startup also plans to build an “isotope production” business, using the copious volume of high-energy neutrons generated by fusion to manufacture valuable isotopes. The company made headlines last year with its claim that fusion-generated neutrons could transmute mercury into an unstable isotope that eventually decays into gold — potentially doubling a fusion reactor’s economic output (and proving the old alchemists right). But that work is still theoretical, based on computer simulations rather than peer-reviewed or experimentally validated work.
Marathon certainly has plenty to keep it busy in the near term, though. “There is a really amazing opportunity right now to say, look, the fusion supply chain is ready to go. We can start scaling up,” Schiller told me. “The science will progress in parallel, and we really want to land this together — not wait another 10 years after scientific results come in.”
Current conditions: Temperatures in Sicily and southern Italy are approaching 100 degrees Fahrenheit as a heat dome settles over the north-central Mediterranean • After pounding Okinawa and injuring two people on Japan’s remote southern islands, Typhoon Saudel is barreling west toward China • A geomagnetic storm known as a coronal hole could create a visible aurora from New York to Idaho, causing minor disruptions to technological devices such as GPS.

It’s like something out of an apocalyptic disaster film. From a camera situated on a cliffside overlooking the Rasuwagadhi border checkpoint in a valley between Nepal and Tibet, you watch as several — then dozens — of people start running away from the building. Birds fly across the screen in the same direction. Finally, after a few seconds, you see what they’re trying to escape: A giant wall of gray, muddy water crashing into the roughly six-story building like an ocean wave against a sand castle. In other videos, cars, trees, and homes disappear under the roar of a river of mud and rocks. Goliath boulders roll like basketballs. Men run for their lives. An avalanche on the Chinese side of the border “triggered a wall of water with no warning,” wrote The Kathmandu Post, an English-language daily in the Nepali capital, declaring this “one of Nepal’s deadliest disasters in decades.” By Thursday morning, the death toll counted at least 332, with hundreds more people still missing. Nepal’s disaster authority told the Indian broadcaster NDTV that a “chunk of snow and rock broke off near a glacier zone” on the border and either “fell into a glacial lake or blocked the river channel” resulting in a surge that swelled into a wave of glacial ice, meltwater, and debris. While initial reports suggested the avalanche started with an earthquake, a U.S. Geological Survey analysis found that the avalanche itself set off a magnitude 5.2 landslide.
Last month the Federal Communications Commission banned the use of new types of foreign-made inverters, the equipment needed to patch solar panels and batteries onto the grid, citing the need to protect the U.S. artificial intelligence buildout from Chinese sabotage. Now the White House is stepping in to block foreign imports of yet more types of grid equipment. In an executive order Wednesday, President Donald Trump said that “continued United States reliance on foreign sources of bulk-power system electric equipment with these potential national security vulnerabilities also creates a supply chain vulnerability that could eliminate the supply of these products in the United States as a result of disruptions in international trade.” In particular, the order will affect transformers, which are facing a years-long backlog as manufacturers struggle to keep up with demand from both the data center buildout and repairs to the grid after extreme weather mangles power equipment. The Biden administration had sought to increase the energy efficiency standards for transformers, paralyzing manufacturers who opposed the regulation and could not make investments into new assembly lines to meet surging demand until the fate of the rule was resolved. The Biden-era Department of Energy ultimately withdrew its proposal. While the Trump administration policy now will further protect those domestic factories, the import restrictions could, in the meantime, make obtaining the equipment primarily made overseas more difficult.
The Trump administration is set to speed up permitting reviews for oil and gas drilling in the Arctic. On Wednesday, Public Domain broke news that the Department of the Interior is planning to publish a categorical exclusion to the National Environmental Policy Act “that would make it easier for the oil and gas industry to conduct seismic surveys, obtain rights of way, and drill new exploration wells” in the National Petroleum Reserve in Alaska, a nearly 36,000-square-mile area on the continent’s northern Arctic Ocean coast.
The proposal, which the Interior Department confirmed, comes as a particularly devastating blow to the Native Village of Nuiqsut, which had brokered a deal with the Biden administration to create a nearly million-acre caribou reserve to foster a herd on which the indigenous residents have long depended. But former Nuiqsut Mayor Rosemary Ahtuangaruak told the public-lands-focused investigative site that new drilling activity around the village has already changed the herd’s migration patterns. “All of the contractual agreements that were supposed to guide how development is going to occur have been ripped out of the books,” she said. “We feel that it doesn’t matter that we have a unique DNA, a small community of 500 people, that are just being totally disregarded and sacrificed for the greed of development.”

Back in May, I told you about Otovo, the new startup from the former chief executive of defunct rooftop solar giant Sunnova. Instead of installing solar panels, the new company repairs rooftop photovoltaic units, in addition to batteries and generators — a sort of AAA for home energy equipment. Otovo started in Norway, targeting millions of homeowners across Europe with solar panels from installers that went out of business and left customers without maintenance service. The company has mounted a global expansion into the United States by buying smaller solar companies and maintenance providers. On Thursday, Otovo plans to announce two deals to make its latest acquisitions: Oahu-based PV Hawaii and Mr. Elektro in Norway and Sweden. The combined value of the deals — which are being reported first in this newsletter — is about $4.6 million. “PV Hawaii and Mr. Elektro bring licensed, experienced local teams that strengthen how we serve customers, and they extend our platform into Hawaii for the first time while deepening our reach across Norway and Sweden,” Otovo CEO John Berger told me in a statement.

You read that right. Unless you (like, uh, some people…) are familiar with late 20th century Melanesian geopolitics, you may not know the story of Bougainville. The island province off Papua New Guinea long had a troubled history. Ethnically, its people are related to those of the Solomon Islands, but German colonial borders hemmed the mineral-rich isle into the territory controlled by Port Moresby. In the 1970s, Anglo-Australian mining giant Rio Tinto built the Panguna mine in the center of the island. Pollution and labor violations plagued the open-pit copper and gold mine, ultimately fueling a separatist rebellion. A conflict, known as the Bougainvillean Civil War, erupted in 1988 and lasted for 10 years, only ending with a peace accord that allowed for a referendum on independence. In 2019, the autonomous province voted nearly unanimously in favor of breaking away from Papua New Guinea. The non-binding vote has yet to be ratified by the parliament in Port Moresby. But the leaders of Bougainville expect to become the world’s newest country by 2030.
To fund its sovereignty, the island wants to reopen Panguna. Last November, Ishmael Toroama, the president of Bougainville, signed a memorandum of understanding with Lloyds Metals and Energy. The Indian iron-ore miner won the deal “despite warnings from Bougainville’s majority state-owned mining company, Bougainville Copper, that Lloyds lacked the technical and financial capacity of rival bidders,” the Organized Crime and Corruption Reporting Project reported in a major new investigation. Just a month earlier, Toroama confirmed to OCCRP, “he accepted an offer from Lloyds’ managing director Balasubramanian Prabhakaran to arrange for his wife to travel to India and have a life-saving kidney operation at no cost to the president.” Toroama told OCCRP that the gift did not weigh on his decision to select the Mumbai-based Lloyds for the project.
The first step in the Department of Energy’s effort to propel new reactor technologies to market was a pair of pilot programs to speed up development of projects from both power and fuel producers. The next step is the “nuclear launch pad” initiative at the Idaho National Laboratory’s National Reactor Innovation Center. This week, the agency announced the first 12 companies to participate in the new program, which bills itself as providing “flexible technical and regulatory frameworks designed to fast-track paths from concept to deployment.” The list includes microreactor developers Antares Nuclear, Atlas Atomics, Oklo, Valar Atomics, Scaled Atomics, and two projects from Deployable Energy; fuel makers Forge Atomics, Hexium, Lightbridge Corporation, Raven-Flint Nuclear, and Sublime Nuclear; and medical isotope startup Nusano. “These selections show a strong and growing interest from developers ready to move their technologies forward,” Brad Tomer, the director of the National Reactor Innovation Center, said in a statement. Meanwhile, another startup spinning out from the Massachusetts Institute of Technology announced a big initial funding round. Apollo Atomics — which aims to build next-generation pressurized water reactors, the type of reactor that makes up the bulk of the global fleet — announced a $31 million seed financing round, NucNet reported.
Rob talks with Amanda Levin, head of climate science and policy at the Natural Resources Defense Council, about why we shouldn’t give up on renewable subsidies just yet.
Two years ago, Donald Trump made an outlandish campaign promise: He would cut Americans’ power bills in half.
It was a ridiculous, impossible pledge — but even so, the affordability problem didn’t need to get this bad. A new report, out this week from the Natural Resources Defense Council, looks at the economic, environmental, and public health costs of Trump’s regulatory and legislative clean energy policies, including his rollback of the wind and solar tax credits.
The report’s author, Amanda Levin, joins Rob on this episode of Shift Key. Levin is a Director of Policy Analysis at the NRDC’s Science Office. They discuss why Trump’s repeal will have long-term effects, the underrated public health impacts of the rollback, and why Levin believes the credits should be restored.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap News.

Here is an excerpt from their conversation:
Robinson Meyer: So you’ve said that we should have tax credits that buy down the cost of technologies while we’re installing them. We had Lily Bermel on Shift Key a few weeks ago with her report, and she looked at a different set of questions here, and I think it’s worth kind of talking about them in a second. But her view of the data — which I would say I’ve also heard now from some solar developers, who obviously represent the interests of their industry — but her view of the data was like, look, there’s a lot of solar and batteries that are about to get built as developers rush to hit a deadline, rush to hit the deadline in the One Big Beautiful Bill Act. Her view is, if you look at this from an emissions perspective, you don’t need wind and solar tax credits. So really ,money would be better spent elsewhere. It would be better spent buying down the cost of clean firm technologies like advanced geothermal, like fusion, perhaps, that can run 24/7 and start to push gas out of the system.
You’ve written an op-ed for Heatmap kind of taking issue with some of those claims, and I want to actually lean into that disagreement. Why should the U.S. restore wind and solar tax credits? Because I would say we’ve learned one thing, actually, in the past month since Lily was on the show. It is that deficit concerns are going to be even more pressing for lawmakers, it seems like, in 2029, even in 2027, than they were in 2024 or 2022, because interest rates are going to be high. They seem to be getting higher. Among the crises that Democrats will have promised to solve is this deficit crisis that is of Trump’s own creation. And so why should a scarce dollar go to wind and solar tax credits?
Amanda Levin: I think it’s important to remember that renewables have a lot of benefits, and not all of them are reflected in the decisions that a utility might make on behalf of its customers. Renewables both lower pollution, which can help reduce the costs and the burden that we have both from public health pollution as well as from climate pollution. They also can enhance energy security and increase economic opportunities.
But I think importantly, it’s a recognition of, one, we need to build a lot of energy fast, and we want to build it clean, as well. And that is going to take quite a bit of money up front. Even if wind and solar are some of the cheapest, lowest cost options over the life of their investment, when looking at something more simplistic, like a levelized cost of energy, it doesn’t mean that they don’t have large upfront costs that need to then be recovered from someone. And in the structure of many of our states, that someone is going to be ratepayers. And often the way that we recover money through electricity bills and rates is not progressive. It’s pretty regressive. So I think the way that we see the kind of tax credits playing into this is it’s an essential part of ensuring that as we transition towards a cleaner system, it remains affordable for everyone by moving costs off of ratepayers, who are going to be much more regressively taxed, and putting them onto the federal government, when we know that we need to be spending more on clean energy to meet our growing load, and also just to invest in our grid that is, in many cases, reaching the end of its life for certain investments.
And so I think to that kind of question of what are we trying to solve here? Obviously, wind and solar, we still see that they are being built, and they make up the bulk of anything that’s going to be built in the next decade. But we’re definitely not building enough.
There was a paper that I was part of at the beginning of 2025 that found that in order to meet our climate commitments, we would need to quadruple the amount of wind, solar, and battery storage that was being added to the system compared to recent day records. The IRA got us basically halfway there. And if you look at where we are now with Trump, we’ve basically lost that halfway there. But what we know is, if we want to actually tackle our societal challenges — climate, health, everything — and affordability, we’re going to both need to build a lot of clean energy, but also we can’t put that on the backs of ratepayers. We need to explore other ways to mitigate the near-term affordability shock that will come from just having to invest in our system.
