A senior scholar at Columbia University’s Center on Global Energy Policy on what Trump has lost by dismantling Biden’s energy resilience strategy.

A fossil fuel superpower cannot sustain deep emissions reductions if doing so drives up costs for vulnerable consumers, undercuts strategic domestic industries, or threatens the survival of communities that depend on fossil fuel production. That makes America’s climate problem an economic problem.
Or at least that was the theory behind Biden-era climate policy. The agenda embedded in major legislation — including the Infrastructure Investment and Jobs Act and the Inflation Reduction Act — combined direct emissions-reduction tools like clean energy tax credits with a broader set of policies aimed at reshaping the U.S. economy to support long-term decarbonization. At a minimum, this mix of emissions-reducing and transformation-inducing policies promised a valuable test of political economy: whether sustained investments in both clean energy industries and in the most vulnerable households and communities could help build the economic and institutional foundations for a faster and less disruptive energy transition.
Sweeping policy reversals have cut these efforts short. Abandoning the strategy makes the U.S. economy less resilient to the decline of fossil fuels. It also risks sowing distrust among communities and firms that were poised to benefit, complicating future efforts to recommit to the economic policies needed to sustain an energy transition.
This agenda rested on the idea that sustaining decarbonization would require structural changes across the economy, not just cleaner sources of energy. First, in a country that derives substantial economic and geopolitical power from carbon-intensive industries, a durable energy transition would require the United States to become a clean energy superpower in its own right. Only then could the domestic economy plausibly gain, rather than lose, from a shift away from fossil fuels.
Second, with millions of households struggling to afford basic energy services and fossil fuels often providing relatively cheap energy, climate policy would need to ensure that clean energy deployment reduces household energy burdens rather than exacerbates them.
Third, policies would need to strengthen the economic resilience of communities that rely heavily on fossil fuel industries so the energy transition does not translate into shrinking tax bases, school closures, and lost economic opportunity in places that have powered the country for generations.
This strategy to reshape the economy for the energy transition has largely been dismantled under President Trump.
My recent research examines federal support for fossil fuel-reliant communities, assessing President Biden’s stated goal of “revitalizing the economies of coal, oil, gas, and power plant communities.” Federal spending data provides little evidence that these at-risk communities have been effectively targeted. One reason is timing: While legislation authorized unprecedented support, actual disbursements lagged far behind those commitments.
Many of the key policies — including $4 billion in manufacturing tax credits reserved for communities affected by coal closures — took years to move from statutory language to implementation guidance and final project selection. As a result, aside from certain pandemic-era programs, fossil fuel-reliant communities had received limited support by the time Trump took office last year.
Since then, the Trump administration and Congress have canceled projects intended to benefit fossil fuel-reliant regions, including carbon capture and clean hydrogen demonstrations, and discontinued programs designed to help communities access and implement federal funding.
Other elements of the strategy to reduce the country’s vulnerability to fossil fuel decline have fared even worse under the Trump administration. Programs intended to help households access and afford clean energy — most notably the $27 billion Greenhouse Gas Reduction Fund — were effectively canceled last year, including attempts to claw back previously awarded funds. More broadly, the rollback of IRA programs with an explicit equity or justice focus leaves lower-income households more exposed to the economic disruptions that can accompany an energy transition.
By contrast, subsidies and grant programs aimed at strengthening the country’s energy manufacturing base have largely survived, including tax credits supporting domestic production of batteries, solar components, and other key technologies. Even so, the investment environment has weakened. Automakers have scaled back planned U.S. battery manufacturing expansions. Clean Investment Monitor data shows annual clean energy manufacturing investments on pace to decline in 2025, after rising sharply from 2022 to 2024. Whatever one believed about the potential to build globally competitive domestic supply chains for the technologies that will power clean energy systems, those prospects have dimmed amid slowing investment and the Trump administration’s prioritization of fossil fuels.
Perhaps these outcomes were unavoidable. Building a strong domestic solar industry was always uncertain, and place-based economic development programs have a mixed track record even under favorable conditions. Still, the Biden-era approach reflected a coherent theory of climate politics that warranted a real-world test.
Over the past year, debates in climate policy circles have centered on whether clean energy progress can continue under less supportive federal policies, with plausible cases made on both sides. The fate of Biden’s broader economic strategy to sustain the energy transition, however, is less ambiguous. The underlying dependence of the United States on fossil fuels across industries, households, and many local communities remains largely unchanged.

The spinoff of Lawrence Livermore National Lab has a new 10-point plan to get onto the grid by the 2030s.
One of fusion energy’s newest startups, Inertia Enterprises, is betting that the fastest route to commercial fusion runs through one of the field’s oldest ideas. The company, which raised a $450 million Series A earlier this year, plans to build a power plant based on the laser-driven fusion system pioneered at Lawrence Livermore National Laboratory’s — the only tech yet to have produced more energy from a fusion reaction than it took to initiate it. Now, Inertia has shared its commercialization roadmap exclusively with Heatmap, detailing the 10 near-term capabilities it must demonstrate before this landmark experiment can become a grid-scale power plant by the mid-2030s.
The roadmap offers a route from the national lab’s impressive but commercially impractical fusion demonstrations to an economical power plant capable of producing electricity for the grid. At its core are a set of milestones — mostly aimed at developing cheap, mass-manufacturable components — that Inertia says it must clear before those individual systems can be integrated into a working plant. This road is not necessarily linear, however, as various teams will likely be working on many of these goals simultaneously.
At least the physics of Inertia’s approach are already proven, the startup’s CEO Jeff Lawson told me, pointing to the fusion experiments at Lawrence Livermore’s National Ignition Facility as a proof-of-concept. The lab’s demonstration of net energy gain caps more than six decades and $30 billion (in 2026 dollars) of U.S. fusion research. The remaining challenges, he argued, are all engineering-related, requiring “elbow grease, hard work, and smart people” rather than breakthroughs in fusion science.
"It seems to us like a startup or a commercial company of any variety should be focused on commercializing a proven scientific result, as opposed to actually trying to demonstrate the basic science to begin with," Lawson told me. Basic science, he argues, is better left to national labs and universities, where researchers can pursue "unbounded problems" that don’t align with the expectations and timelines of venture-backed startups.
Indeed, no fusion startup has yet achieved scientific breakeven, the milestone Lawrence Livermore first hit in 2022, and has since repeated numerous times. But leading players such as Commonwealth Fusion Systems and Helion Energy maintain that it’s only a matter of time before they validate the physics behind their own reactor designs, which they claim will be highly cost-competitive.
Lawson, on the other hand, readily acknowledged that Lawrence Livermore’s tech is uneconomical in its current form. His bet is simply that the more predictable path to a commercial reactor is to drive down the cost of the lab’s validated fusion approach, known as inertial confinement. This system relies on high-powered lasers firing at a millimeter-scale pellet of fusion fuel, compressing it to extreme temperatures and pressures until the atoms fuse. Today, the National Ignition Facility makes each individual fusion target by hand, a workable solution given that it only uses about a dozen per year.
That production model, however, isn’t remotely plausible for a grid-scale power plant. Because each fusion reaction lasts just a fraction of a billionth of a second, a commercial facility must fire its lasers at a fresh target about 10 times per second to generate continuous electricity — requiring the production of hundreds of millions of targets each year.
Scaling production to roughly a million pellets per day and making them inexpensive enough for commercial operation without compromising the strength or precision required for fusion ignition is central to Inertia’s roadmap. That includes goals five, seven, eight and nine — industrializing the manufacturing of the carbon shells that hold the fusion fuel, making the thin films that hold those carbon shells both durable and cheap, scaling up and automating fusion target assembly, and speeding up how fast targets are filled with the requisite deuterium-tritium fuel.
The other central focus of the roadmap is the laser system, which will ultimately consist of 1,000 individual units operating in concert to compress and heat the fusion fuel. Key priorities include reducing the system’s cost (goal two), dramatically increasing its firing cadence (goal three), and bolstering its durability to withstand high-intensity operations (goal four). Goal six also complements these efforts, calling for the development of a control system capable of tracking moving fusion targets to precisely align each laser shot.
Goals one and 10 bookend the journey with some broader milestones. The first focuses on increasing the fusion target’s energy gain — the ratio of fusion energy produced to laser energy delivered — to more than 25 times ignition. Today, the National Ignition Facility’s best-performing laser shot has yielded a gain of just over four times what it took to start the reaction. Goal 10 then zooms out to the ultimate objective: integrating all these technologies into a commercially viable power plant that can deliver either electricity or industrial heat to end customers.
To reach that point, Inertia has embarked on an industrial engineering hiring spree, recruiting folks with experience taking complex hardware systems from prototype to mass production, “not unlike the processes that are used in the semiconductor or consumer electronics world,” Lawson explained. The company has been making progress on its component development goals since the beginning of the year, he told me, and expects to announce the successful demonstration of a few of these milestones in the coming months. Lawson ultimately expects Inertia to complete the core components of its laser and target manufacturing systems by the middle of next year.
The team will spend the next two to three years integrating these individual pieces into two fully operational subsystems, a prototype laser system and a target manufacturing line. Around 2030, the company will begin combining those subsystems into a first-of-a-kind fusion power plant, which will also serve as the proving ground for the target chamber, tritium fuel breeding system, and power conversion system that turns fusion heat into electricity. By the middle of the next decade, Inertia aims to be generating power from this first plant, setting the stage for the company to build and connect additional grid-scale commercial power plants.
There are plenty of engineering trade-offs that the company will have to solve for. Take the decision around how to size the target chamber, for example. “If you make it bigger, your walls have an easier time and survive longer, but it’s more expensive. If you make it smaller, your walls have a tougher time because they’re closer to all the heat and energy that the fusion reaction is creating, but now your power plant costs less to build.”
But to Lawson, this represents exactly the type of problem Inertia was built to solve: complex engineering issues that come to the fore once scientists have demonstrated the fundamental physics are sound. He thinks other fusion companies may someday reach this stage, as well — though he’s unwilling to hazard a guess on exactly what approach or startup is best positioned to do so.
“There have been generations of scientists who’ve made their predictions about fusion energy and gotten it wrong,” he told me. “I’m not going to pretend to be smarter than them. All I’m here to say is, just knowing that one did work, we can commercialize it.”
