The Inflation Reduction Act is already transforming America. But is it enough?
In the late spring, a scene happened that might have once — even a few years ago — seemed unimaginable.
Senator Joe Manchin and Energy Secretary Jennifer Granholm visited the town of Weirton, West Virginia, to celebrate the groundbreaking of a new factory for the company Form Energy. The factory will produce a new type of iron battery that could eventually store huge amounts of electricity on the grid, allowing solar and wind energy to be saved up and dispatched when needed.
Manchin was clear about why everyone was gathered in Weirton. “Today’s groundbreaking is a direct result of the Inflation Reduction Act, and this type of investment, in a community that has felt the impact of the downturn in American manufacturing, is an example of the IRA bill working as we intended,” he said.
It’s been nearly a year since the Inflation Reduction Act, President Joe Biden’s flagship climate law, passed. The law is successful. It is transforming the American energy system. And the Biden administration is implementing it as fast as it can: Since the law passed, the Treasury Department has published nearly three dozen pieces of complicated rules explaining how the IRA’s billions in subsidies can actually be used.
But is the IRA successful enough? The pace and scale of the climate challenge remains daunting. A recent report from the Rhodium Group, an energy-research firm, found that the United States would only meet its Paris Agreement goal of cutting carbon emissions in half by 2030 with more aggressive federal and state policy.
Here are some broad observations about how the IRA — and the broader project of American decarbonization — is going:
Politically, environmentally, no matter how you look at it: The power sector is the thumping heart of the I.R.A. Because engineers know how to generate electricity without producing carbon pollution — using wind turbines, solar panels, nuclear plants, and more — the sector is central to the law’s implicit plan to decarbonize the American economy, which requires, first, building as much zero-carbon electricity infrastructure as possible, while, second, shifting as much of the rest of the economy to using electricity — as opposed to oil, gas, or coal — as possible.
The electricity industry is also the site of perhaps the law’s most powerful climate policy — and its only policy tied to a national emissions-cutting goal. The law will indefinitely subsidize new zero-carbon electricity until greenhouse-gas pollution from the American power sector falls 75% below its 2022 levels. That means these tax credits could remain in effect until the 2060s, according to an analysis from the research firm Wood MacKenzie.
This was a first for American environmental law, and it remains poorly understood by the public. Even some experts claim that the electricity credits will phase out in 2032 with the I.R.A.’s other subsidies — when, in fact, 2032 is the earliest possible year that they could end.
Which is all to say that it’s early days for understanding the I.R.A.’s effect on the power sector. The data is provisional.
Yet the data is … good. Better than I expected when I started writing this article. The overwhelming majority of new electricity generation built nationwide this year — some 83% — will be wind, solar, or battery storage, according to federal data. Although that mostly reflects projects planned before the IRA was passed, it’s still a giant leap over previous years, and it suggests that the law might be giving clean electricity a boost at the margin:
The solar industry, in particular, is surging. The industry just had its best first quarter ever, with rooftop installations booming and some big utility-scale solar farms finally coming online.
But solar can’t power the entire grid, and other renewables are having more trouble. I’m particularly worried about offshore wind. To build a new offshore-wind project, companies bid for tracts of the ocean floor in a government-run auction. Yet many of those bids failed to account for 2021 and 2022’s rapid inflation, and some developers are now on the hook for projects that don’t pencil out. Most outside analysts now believe that the Biden administration will fall short of its goal to build 30 gigawatts of offshore wind by 2030.
Get one great climate story in your inbox every day:
The boom in electric vehicle and battery manufacturing is clearly the I.R.A.’s brightest spot. (The two industries are one and the same: If you have a giant battery, you’re probably going to put it in an EV; and about a third of every EV’s value comes from the battery.)
Since the IRA passed, 52 new mining or manufacturing projects have been announced, representing $56 billion in new investment, according to a tracker run by Jay Turner, a Wellesley College professor. If you zoom out to all of Biden’s term, then more than $100 billion in EV investment has been announced, which will create more than 75,000 jobs, according to the Department of Energy.
It remains to be seen, however, whether this investment will produce the kind of durable, unionized voter base that the Biden administration hopes to form. So far, much of this investment has flowed to the Sunbelt — and in particular, to a burgeoning zone of investment from North Carolina to Alabama nicknamed the “Battery Belt.” These states are right-to-work states with a low cost-of-living, like much of the states that have absorbed manufacturing investment since the 1980s.
This might make Republicans think twice about undermining the IRA, but it might also be a missed opportunity.
In order to cheaply decarbonize its grid, America needs better power lines. Building long-range, interregional electricity transmission will allow the country to funnel clean energy to where it’s needed most. According to a team led by Jesse Jenkins, a Princeton engineering professor, 80% of the IRA’s carbon-reduction benefits could be lost if the United States doesn’t quicken the pace of new transmission construction. (Other models are less worried.)
Yet the effort to build more power lines — and the broader campaign to reform some rules governing permitting and land use, especially the National Environmental Policy Act — is probably over, at least in this Congress. Republican lawmakers figured out that Democrats are desperate for transmission reform, and they were prepared to make the party pay a high price for it — too high a price for much of the caucus. The bipartisan deal to raise the debt-ceiling also contained many of the moderate permitting reforms that Democrats might have accepted as part of a broader bargain over transmission.
Democrats are now stuck hoping that the Federal Energy Regulatory Commission, or FERC, will make smaller, more technocratic improvements to the transmission process when they take a majority of the commission’s seats early next year.
The biggest programs in the IRA target mature technologies, like solar, wind, and EVs. But the law is full of unheralded programs meant to encourage the development of early-stage climate technologies, such as sustainable aviation fuel. By encouraging technological progress, these programs could abate hundreds of millions of tons of carbon a year in the decades after 2030. They may prove especially important at reducing emissions outside the United States, according to a new analysis from Rhodium Group.
Which is to say that they could be — from a world-historic perspective — some of the law’s most important policies. But for now, few of these programs have been implemented, and we don’t really know how they’re going to go.
Some of them may also be devilishly hard to set up. My colleague Emily Pontecorvo has reported on the difficulty of setting up the tax credits for green hydrogen, which are some of the law’s most generous. If successful, the credits could give the U.S. a major new industry to tackle the decarbonization challenge; if unsuccessful, they could screw up the American electricity system.
Right now, most of the law’s consumer-facing tax credits are continuations of old policies — such as the longstanding subsidy to install rooftop solar — rather than something new. Perhaps the most expansive subsidy that consumers have seen so far is the new $7,500 tax credit for leasing an electric vehicle.
But many more programs will eventually come, including the IRA’s rebates for heat pumps, induction stoves, and electric water heaters. Those programs, some of which must be administered by state offices, have largely yet to be set up. (Even so — and in keeping with other encouraging trends — heat pump sales outpaced furnace sales in the U.S. for the first time last year.)
The Department of Energy is an agency transformed. The IRA held out the opportunity that the agency could metamorphose from an R&D-focused nuclear-weapons storehouse into the federal government’s dynamo of decarbonization. The Biden administration — and Energy Secretary Jennifer Granholm — has seized that opportunity.
As I wrote earlier this year, the agency has stepped into the role of being America’s bureau of industrial policy, replete with its own in-house bank. It has published some of the most detailed and sophisticated federal industrial plans that I’ve ever seen.
And it is getting admirably specific about each of the technologies in its portfolio. In a recent report on the nascent hydrogen industry, for instance, the department said that companies might not build out enough infrastructure because they can’t count on future demand for clean hydrogen. (It’s impossible for firms to invest in making hydrogen if they can’t be sure anyone is going to buy it.) Then, earlier this week, the agency announced a new $1 billion program to buy hydrogen itself, thus providing that demand-side certainty that producers need.
Let’s return to renewables. The United States is striving — but will likely fail — to build 30 gigawatts of offshore wind by 2030. It is building a couple dozen gigawatts of new solar capacity every year. That may seem like a lot: One gigawatt of electricity is enough to power about 825,000 homes.
But annual power demand in the United States is closer to 4,000 gigawatts — and it’s on track to grow as we electrify more and more of the economy. While decarbonizing the grid isn’t as simple as switching one energy source for another, still, it would take more than a century to build 4,000 gigawatts of renewables electricity at our current rate.
It’s a similar story in electric cars. The growth is good: EV sales rose 50% year over year in the first half of 2023. But the challenge is daunting: Electric vehicles made up only 7% of all new car sales in the U.S. during the same period, and decarbonizing the car fleet will eventually require making virtually all new car sales EVs, and then — over the next decade — replacing the 275 million private vehicles on the road.
And that’s the story of the IRA — from renewables to EVs, geothermal to nuclear energy. The trends have never been better. The government has never tried to change the energy system so quickly or so thoroughly. That, by itself, is progress: For decades, the great obstacle of climate change was that the government wasn’t trying to solve it at all.
But decarbonization will require replacing hundreds of millions of machines that exist in the world — and doing it fast enough that we avoid dealing catastrophic damage to the climate system. The IRA is about to take on that challenge head-on. Now we find out if it’s up to the task.
The real work, in other words, is just beginning.

It sure looks that way, at least. Democrats should start coming up with a plan.
For the first six months of President Trump’s term, the big question was about what would happen to the Inflation Reduction Act. We now have something like an answer.
President Trump’s memorably named One Big Beautiful Bill Act repealed many of the IRA’s most important clean energy tax credits, including incentives for wind, solar, and electric vehicles. And while it’s still unclear whether the Trump administration will let developers actually use the tax credits that remain on the books — especially the now-denuded credits for wind and solar — fewer “unknown unknowns” remain about what might come next.
So I’ve been trying to figure out where climate and energy policy might go from here. And one story that I keep coming back to is the flashing red lights around what could become a serious electricity affordability crisis.
It’s now widely understood that electricity demand is rising in the United States for the first time in a generation. The Energy Information Administration projects that electricity use will grow 1.7% in the next few years, after increasing by just 0.1% per year from 2005 to 2020. That growth is projected to come from new data centers, new factories, the (now) slow(er) but (still) steady adoption of electric vehicles, and population growth.
What is less well understood is how poorly the United States is prepared to match this rise in electricity demand with an equivalent increase in supply. To some degree, American electricity prices are already rising: So far this year, utilities have received or requested permission to increase customers’ bills by $29 billion, according to a July report from PowerLines, a think tank and advocacy group. That’s a large number in its own right, and it’s more than twice as much as had been approved at this time last year.
But when you look across the power system, virtually every trend is setting us up for electricity price spikes:
On top of all this, of course, the Trump administration has made it much more uncertain which new solar, wind, and battery projects will be able to secure tax credits — and with them, secure bank financing.
None of these trends alone would guarantee price increases or electricity supply constraints. But taken together, they reveal an electricity system that is coming under a variety of strains.
In the 2010s, cheap natural gas and technological advances in energy efficiency pacified much of the power system. We won’t have the same luxury this decade.
This is all going to be bad for the economy, bad for the climate, and bad for climate policy.
It’s a setback for the U.S. economy because, as President Trump somewhat alluded to in his second inaugural address, energy is a key input to virtually every other economic process, including manufacturing. But it’s especially bad for climate policy. The dominant plan to decarbonize much of the U.S. economy is to “electrify everything” — cars, appliances, home heating, and even many industrial processes. Americans will be far less eager to electrify everything if electricity is expensive.
If energy price hikes do arrive, Democrats are going to have a relatively straightforward time communicating about them in a narrow political sense. The story is just too simple: Democrats passed a law to encourage clean energy called the Inflation Reduction Act. Republicans repealed it. Energy prices inflated. QED.
That story alone might be too contrived, but the evidence we have suggests that OBBBA will raise energy bills. The REPEAT Project at Princeton University — led by Jesse Jenkins, my Shift Key podcast cohost — has a new report out projecting that the One Big Beautiful Bill Act will increase Americans’ electricity bills by $165 a year by the end of the decade. (If the law is allowed to stick around, and in the absence of intervening policies, it could raise bills by hundreds of dollars a year by the middle of next decade.)
OBBBA’s explosion of the federal deficit will make the situation worse: By expanding the deficit for such little public gain — that is, merely to memorialize earlier tax cuts, not even to make new ones — the Federal Reserve will have a more difficult time cutting interest rates in the future. That will in turn make it even more difficult for utilities and developers to finance new energy projects.
The political story will be so compelling here, I think, that Democrats will come under a lot of pressure to reinstate the wind and solar tax credits. And maybe they should do that — it could make sense as part of a larger energy or permitting deal. But stacking more solar and wind on the grid will not on its own lower people’s electricity bills.
Going into 2028, Democrats will need an actual plan to stabilize or cut electricity costs. They will need ideas about how (and whether) to speed up permitting, restructure wholesale power markets, and build new power plants in order to stabilize the power grid.
One thing that’s already clear is that in this inflationary environment, states like New York with publicly owned power authorities are able to intervene more forcefully in their own power markets than states that lack such capability. That’s because the state itself can act to build its own large-scale power plants. New York Governor Kathy Hochul recently directed the state’s power authority to build a new nuclear power plant upstate in order to grow the supply of zero-emissions electricity. Using their state own power authorities, governors in other states — or even the federal government, with an entity like the TVA— could take a similar step.
With all that said, I’ve been trying to come up with a scenario under which these price hikes will not materialize. In the late 2010s, for instance, America’s liquified natural gas exports surged essentially from zero, but domestic consumers didn’t see significant price hikes because drillers increased gas production to match the exports. Maybe that could happen again. And maybe utilities will — and this would, to be clear, be horrible for the climate — run their aging coal plants much more than they once anticipated doing.
Or maybe load growth won’t be as bad as we think. When Jesse and I spoke to Peter Freed, Meta’s former director of energy strategy, for Shift Key, he told us that the current data center boom is different from any previous buildout because of the presence of speculators. For the first time, he said, speculative data center developers are buying up prospective sites and requesting utility-scale hookups with the expectation that they will find a tenant for the data center in the future. In other words, the demand side of the electricity system is filled with an unusual amount of froth at the moment.
We also know that, more generally, the demand side of the power system is a mess. In the past few years, climate analysts have gotten used to talking about the power grid’s interconnection queue — that is, its supply side. But the demand-side queue — the process that lets new data centers, factories, and other new electricity users connect — is even more broken. In some jurisdictions, it’s little more than an Excel file that projects move up and down within as local politics requires.
We also know that one source of new demand — one planned factory or, more often, one data center — will sometimes apply to hook up to multiple states or utilities at the same time. It will get utilities to bid against each other, suss out the best construction sites and power rates, and only relatively late in the process make a final decision about where to build.
So if I were putting together a bear case for electricity demand, I would start here. Maybe aggressive data center speculators are bidding in multiple utilities, driving up projections across many states. That’s causing utilities to freak out about their supply, leading them to project the need for a lot of new investment — and, with it, a lot of electricity rate increases. But as data center speculators actually begin to build (or abandon) projects — and as some of the air inevitably comes out of the AI boom — some of this projected demand will start to evaporate. Perhaps the data centers that do get built will find ways to reduce their power usage, too.
Even this story won’t fully eliminate load growth on its own, though. Data centers make up the largest share of new electricity demand, but even then, they’re not the majority of it. The rest comes from, roughly, new factories, the slow electrification of the vehicle fleet, and new residential construction. But let’s say the One Big Beautiful Bill Act succeeds in hobbling the electric vehicle sector in the United States, many EV and battery factories get canceled, and fewer Americans buy EVs overall. Calculate in a mild recession, too, since all the AI and EV investment will be drying up.
In that world, most new sources of power demand really will be in abeyance. That’s how some of these power projections might not come true. But in most other scenarios, it’s time to hold on — and for blue-state leaders to think about how they can find cheap, zero-emissions electrons, as soon as possible.
The Department of Energy announced Wednesday that it was scrapping the loan guarantee.
The Department of Energy canceled a nearly $5 billion loan guarantee for the Grain Belt Express, a transmission project intended to connect wind power in Kansas with demand in Illinois that would eventually stretch all the way to Indiana.
“After a thorough review of the project’s financials, DOE found that the conditions necessary to issue the guarantee are unlikely to be met and it is not critical for the federal government to have a role in supporting this project. To ensure more responsible stewardship of taxpayer resources, DOE has terminated its conditional commitment,” the Department of Energy said in a statement Wednesday.
The $11 billion project had been in the works for more than a decade and had won bipartisan approval from state governments and regulators across the Midwest. The conditional loan guarantee announced in November 2024 would have secured up to $4.9 billion in financing to fund phase one of the project, which would run from Ford County in Kansas to Callaway County in Missouri.
In response to a request for comment, an Invenergy spokesperson said, “While we are disappointed about the LPO loan guarantee, a privately financed Grain Belt Express transmission superhighway will advance President Trump’s agenda of American energy and technology dominance while delivering billions of dollars in energy cost savings, strengthening grid reliability and resiliency, and creating thousands of American jobs.”
The project had long been the object of ire from Missouri Senator Josh Hawley, who recently stepped up his attacks in the hopes that a more friendly administration could help scrap the project. Two weeks ago, Hawley posted on X that he’d had “a great conversation today with @realDonaldTrump and Energy Secretary Chris Wright. Wright said he will be putting a stop to the Grain Belt Express green scam. It’s costing taxpayers BILLIONS! Thank you, President Trump.” The New York Times later reported that Trump had made a call to Wright on the issue with Hawley in the Oval Office.
Hawley celebrated the Grain Belt Express decision, writing on X, “It’s done. Thank you, President Trump,” and exulting in a separate post that “Department of Energy officially TERMINATES taxpayer funding for Green New Deal ‘grain belt express.’”
The senator had claimed that the plan would hurt Missouri farmers due to the use of eminent domain to acquire land for the project. In 2023, Hawley wrote a letter to Invenergy chief executive Michael Polsky claiming that “your company’s Grain Belt Express construction campaign has hurt Missouri’s farmers,” and that “they have lost the use of arable land, seen their property values decline, and been forced to operate under a cloud of uncertainty.”
Controversy over eminent domain and the use of agricultural land by transmission lines illustrates the difficulties in building the long-distance energy infrastructure necessary to decarbonize the grid.
Opposition to the project had been gestating for years but picked up steam in recent weeks. Earlier this month, Andrew Bailey, the Republican attorney general of Missouri, announced an investigation into the project. “This is a HUGE win for Missouri landowners and taxpayers who should not have to fund these green energy scams,” he wrote on X Wednesday following the DOE’s announcement.
As the project appeared to be more imminently imperiled, Invenergy scrambled to preserve its future, including making plans to connect gas to the transmission line. In a letter to Secretary of Energy Chris Wright written earlier this month, the Invenergy vice president overseeing the project wrote that the Grain Belt Express “has been the target of egregious politically motivated lawfare,” echoing language President Trump has used to describe his own travails.
If the author’s intent was to generate sympathy from the administration, it didn’t work. The end of the loan guarantee could be a death blow to the project, and will at the very least force Invenergy into a mad dash to try to match the lost capital.
Editor’s note: This story has been updated to include a comment from Invenergy.
The grant from Washington State will fund a facility where all kinds of fusion labs can run tests of their own.
Flash back to four summers ago, when aspiring fusion pioneers Robin Langtry and Brian Riordan were stuck designing rockets at Blue Origin, Amazon CEO Jeff Bezos’ aerospace and space tourism company. More specifically, they were ruminating on how their engine’s large size was preventing the team from iterating quickly.
“If your rocket engine is 12 feet tall, there’s like, three places in the country where you can get castings,” Langtry told me. One simple design change could mean another eight to nine months before the redesigned part came in. Smaller designs, they hypothesized, would lead to faster development cycles.
They decided to quit their jobs in June of 2021 and put their thesis to the test with what would become Avalanche Energy, a fusion startup aiming to commercialize tabletop-sized reactors via magneto-electrostatic fusion, a nascent technology that’s far less well-understood than even still-experimental large-scale fusion machines like tokamaks and stellarators. Today, though, Washington State is giving this emergent tech a big vote of confidence by announcing one of the largest government-led fusion investments to date: A $10 million grant for Avalanche to build out a commercial-scale test facility for fusion technologies.
This facility, called FusionWERX, is where Avalanche will test its own prototypes with the goal of achieving scientific breakeven — the point at which a fusion reaction produces more energy than the energy used to initiate the reaction. But as Langtry, the company’s CEO, explained to me, it will also be a hub where other fusion companies, universities, and national labs can come test their own proprietary technologies while keeping their intellectual property intact.
“It’s almost like a commercial wind tunnel test facility, but for fusion,” Langtry told me. For example, Avalanche’s early-stage reactors will produce neutrons that researchers can use to test novel materials and ensure they can withstand the extreme conditions found inside fusion reactors. Organizations can also test their own neutron capture methods, often referred to as "neutron blankets,” which are critical for producing the tritium fuel that’s needed for a sustained fusion reaction.
Thus, Avalanche will earn revenue from the groups using the FusionWERX facility well before it makes any money from commercial energy production. The startup also plans to bring in additional income by making and selling radioisotopes — atoms that emit radiation as they decay — for medical and energy applications such as diagnostic imaging, radiation therapy, and nuclear batteries that can generate electricity in space or remote areas like the deep ocean.
Langtry told me these additional opportunities make Avalanche attractive to a wider variety of investors than simply climate tech venture capitalists interested in fusion’s potential for utility-scale power generation. “There’s much bigger sources of capital if you can build a true business that commercializes this technology and generates revenue and scales it,” Langtry told me. “That’s really what we’re about.”
Prior to the $10 million grant, Avalanche had raised a total of $50 million from investors such as Lowercarbon Capital, Peter Thiel’s Founders Fund, and Toyota Ventures. And while the startup’s lineup of near-term use cases sets it apart, Avalanche too is ultimately aiming to produce commercially-relevant energy, with an eye towards replacing diesel generators for data center backup power or for use in remote communities or military outposts.
Avalanche’s chosen method, magneto-electrostatic fusion, uses ions that are injected into the reactor’s chamber and confined with extremely high voltage. This strong electric field accelerates the ions towards the center of the reactor, where they collide to produce a fusion reaction. Magnets surrounding the chamber also work to trap electrons alongside the ions, increasing the density of the plasma to achieve high fusion rates.
Avalanche announced today that it has successfully operated its machine at 300 kilovolts for multiple hours. When adjusted for size, this equates to 6 megavolts per meter, twice the voltage density of lightning. To reach breakeven, the company will need to operate its machine at about 700 kilovolts, which Langtry told me can be done by doubling the size of the reactor’s radius from 6 centimeters to 12 centimeters. Avalanche said in a follow up email that the company is waiting to gain operational experience at its current scale before raising the capital it will take to build a larger reactor.
The magneto-electrostatic method is well-suited to micro reactors as it doesn’t rely on giant magnets or lasers to create the fusion reaction. Ultimately, Avalanche plans to produce modular reactors from 5 kilowatts to 1 megawatt in size — enough to power just a couple homes at the least, and about 1,000 homes at the most.
But powering homes isn’t what Avalanche will actually do. Before energy dominance was even in vogue, the company was already focused on military applications for its tech. It received a contract from the Department of Defense’s Defense Innovation Unit in 2022 to develop technology for a nuclear-powered spacecraft by 2027. Avalanche did not elaborate on what its initial prototype might look like or be used for, only writing in a follow-up email that it’s “in active discussions about next steps for maturing this technology with DOD.”
“We were sort of contrarian, in that we always thought our path to commercial operations was through DOD and space, whereas most of the fusion companies were raising on climate and clean energy and building massive clean energy power plants,” Langtry told me. He cited support from Thiel, perhaps Silicon Valley’s most influential conservative voice, as helping influence the company’s direction.
At this moment, Langtry told me, there’s excitement around using Avalanche’s tech to make President Trump’s vision of a so-called “Golden Dome” missile defense system a reality. This would involve using satellites — theoretically powered by Avalanche — that could track and shoot down ballistic missiles fired at the U.S. “Right now, with solar, [satellites] could probably only take one shot during an engagement. But if you had 100 kilowatts or a megawatt, you could shoot continuously, and that system would be a lot more capable,” Langtry explained to me.
Depending on your feelings about nuclear war, this vision may bring more anxiety than comfort. It’s also a far cry from the more typical — and endlessly more idyllic — narrative of limitless clean energy and unprecedented prosperity that I’m used to hearing fusion enthusiasts promote. But such is the moment. And if the path to commercial fusion ends up running through a satellite-powered missile defense system, it probably won’t be the weirdest clean energy story of the Trump era.
