As blue states double down on renewables, a backlash is growing in red states.

The Inflation Reduction Act was the star of the show in statehouses across the United States this year. As state leaders wrapped up their legislative sessions, many not only tightened their own climate plans, but delivered an encore to the IRA by passing policies to maximize their share of the new federal clean energy funding.
But the applause hasn’t been universal. In a few key Republican-led legislatures, Biden’s climate maneuvers have produced a backlash. Lawmakers pushed through bills that could make cutting emissions a lot harder, making the map of U.S. climate policy start to look as polarized as that of abortion rights or gun control laws.
“There has been a tendency to think about the energy transition as almost automatic when the cost of clean energy technologies come down,” Matto Mildenberger, a political scientist at the University of California-Santa Barbara, told me. “But politics is a really important dimension that's often missed.”
Let’s look at a few examples. Back in February, Minnesota passed a law requiring the state’s utilities to use 100% carbon-free electricity by 2040. Democrats had just taken over the legislature, and they were just warming up. In April they created a $156 million “competitiveness fund” to help agencies and cities compete for the IRA’s clean energy programs. And last week, Democratic Governor Tim Waltz signed two additional laws, one earmarking funding for heat pumps and electric vehicles, and the other creating a new sales tax to support public transit.
Democrats took a similar approach in Colorado, passing new tax credits for many of the same technologies that the IRA funds to try and attract as much federal money into its economy as possible. Coloradans are now eligible for a $7,500 EV tax credit that can be stacked on the federal credit for a juicy $15,000 incentive.
Meanwhile, New York passed the first state-level ban on natural gas in new buildings in the country. Policymakers there also directed a state-run utility to start building renewable energy projects, taking advantage of a little-known provision in the IRA that enables public entities and nonprofits to cash in on federal tax credits.
But in other states, electeds are enacting what you could call anti-climate policies. Montana’s Republican Governor Greg Gianforte recently signed a law that bars state agencies from even considering greenhouse gas emissions when conducting environmental reviews for major projects. The legislature there also passed measures preempting local governments from requiring new buildings to be solar panel or EV-ready, and from placing any restrictions on the use of natural gas. At least 20 other states have enacted similar natural gas ban preemptions in recent years. A new anti-climate copycat bill also spread to a few states this year — Ohio and Tennessee each passed laws classifying natural gas as a source of clean energy.
In Texas, the Republican-controlled legislature is contemplating bills to publicly fund a fleet of new natural gas plants, while placing new, onerous regulations on wind and solar projects. Texas currently produces more wind and solar power than any other state, thanks to lax permitting requirements and an abundance of wind, sun, and undeveloped land. Now, lawmakers want developers of new wind and solar farms — as well as owners of existing projects — to do additional environmental reviews, get new approvals, and pay higher fees. Wind farms would have to be built at least 3,000 feet from neighboring property lines. The rules would not apply to fossil fuel plants.
Though the bill never made it out of committee, a group of Republican lawmakers in Wyoming even sought to “phase out” electric vehicle sales to protect the state’s oil and gas industry. The bill’s lead sponsor later said he supports electric vehicles, and was just trying to send a message to California, which made plans to eventually ban gas-powered vehicles last August.
And while Georgia is often held up as a leader in building a new clean economy, having attracted more clean energy investments since the IRA passed than any other state, Republican lawmakers there recently enacted a tax on public electric vehicle charging.
None of this is particularly surprising or new. To some extent, climate and clean energy policy has long followed party lines. As political scientist Leah Stokes documents in her book Short Circuiting Policy, states like Texas and Ohio have a history of enacting anti-climate policies that slowed the growth of renewables. Those were in large part driven by special interest groups backed by utilities and the fossil fuel industry.
Mildenberger said these efforts are ramping up now because the IRA has made the threat to these industries much more significant. “Increasingly, as some of these technologies are no longer cost competitive in a pure market competition framework, they need to use policy as a rearguard action to try and maintain their market share.”
There is evidence that at least some of these policies, like defining natural gas as clean energy and preempting any bans on the fuel, trace back to special interest groups like the American Legislative Exchange Council and the American Gas Association. What’s new is a push to turn these issues into culture wars by painting natural gas use as a matter of freedom or identity. Republican lawmakers have described a rash of anti-ESG bills, which also have roots with industry groups, as a crackdown on “woke” investing.
But Hanna Breetz, a political scientist at Arizona State University told me it would be a mistake to attribute the trend purely to industry influence or the usual reactionary politics. That view overlooks two other very real factors that she sees contributing to an increasingly polarized environment. One is that people in rural states are legitimately concerned about what a decarbonized future means for them in terms of land use and extraction. They are going to bear the brunt of landscape impacts from vast new solar and wind farms and lithium mines.
The second is genuine risks to reliability from a grid powered by increasing amounts of renewables and batteries that’s also serving an increasing number of electric appliances. “There are some very serious concerns that have yet to be dealt with, particularly in the face of climate change and weather-related issues,” said Breetz. She pointed to a recent report warning of blackouts in some parts of the country this summer, which highlighted diminished capacity from natural gas and coal plants as one potential cause. “I think there's a lot less ideological opposition within utilities than many people assume, and that they are scared to death about a lot of these reliability concerns.”
It’s hard to untangle the role of each of these components — industry influence, party politics, land use concerns, and technical challenges — when they all feed into one another. The effect could intensify as more and more people experience a bad blackout or are faced with a solar farm being built in a place they hold dear.
But also, it might not. If all goes according to Biden’s plan, the IRA will be a countervailing force that brings new jobs and economic growth to areas where political support for clean energy is in short supply. The majority of clean energy project announcements since the IRA was passed are in states like Georgia, Arizona, and South Carolina. Think of the new battery belt emerging in the South, or how many renewable energy projects are popping in Republican-held congressional districts.
“In three or five years that might make some of the extreme rhetoric and policy positions that we're seeing right now on the Republican side of the aisle a little bit more challenging to hold,” said Mildenberger. “My view is that even in some of the more fossil fuel intensive parts of the United States, the question of the energy transition is not if, but when. And to help manage the global climate crisis, that ‘when’ needs to be really soon.”

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.”
