New guidance on the Inflation Reduction Act’s “foreign entities of concern” provision didn’t do much to clarify things.

If you’re in the market for a new car and considering cashing in on the $7,500 federal tax credit for an electric vehicle, I have good news. Also bad news.
The good news is, starting January 1, the credit will be a lot easier to claim. You won’t need to meet a certain level of tax liability to qualify or wait for your tax refund. You can transfer the credit to the dealership and take $7,500 off the sticker price right then and there.
The bad news is that suddenly, nobody knows which — if any — EVs will qualify. On Friday, the Biden administration proposed additional guidelines limiting where the components in eligible EVs are allowed to come from. Those guidelines won’t be finalized until early next year. But all signs indicate that the list of qualifying vehicles is set to shrink.
These changes aren’t coming out of nowhere — they’re part of the way the EV tax credit in the Inflation Reduction Act was designed. Over time, the law phases in additional rules that ask more of automakers in terms of onshoring their production and supply chains and minimizing their reliance on China. Beginning in 2024, if a vehicle contains any battery components that were manufactured or assembled by what’s known as a “foreign entity of concern,” it will no longer meet the requirements for the tax credit. Beginning in 2025, the same rule applies to vehicles containing critical minerals that were extracted or processed by a foreign entity of concern.
What, exactly, is a foreign entity of concern? Under U.S. law, the term applies to a company that is “owned by, controlled by, or subject to the jurisdiction or direction of” North Korea, Russia, Iran, or, yes, China. But what constitutes ownership or control is somewhat fuzzy.
“The implications are enormous because right now, it seems as if every battery that's going into an electric vehicle has some material ties to China,” Jay Turner, a professor of environmental studies at Wellesley College and author of a book on the history of batteries, told me.
In the proposal published Friday, the Biden administration recommended three criteria for interpreting the rule that it hopes will further strengthen American manufacturing of EV components and help diversify supply chains:
1. If the company producing the battery component or mineral is headquartered or incorporated in China, or if the relevant production activities occur in China, the vehicle will not qualify for an IRA tax credit.
2. If China has a 25% or more voting interest, board control, or equity interest in the company producing the component or mineral, the vehicle will not qualify.
3. If a company licenses or contracts with a Chinese firm, and the license entitles the Chinese firm to “exercise effective control” over production, the vehicle will not qualify.
This is a strict interpretation that’s likely to knock some vehicles off the eligibility list. But in a series of meetings with reporters on Wednesday, officials from the Department of the Treasury and Department of Energy said they didn’t know which or how many vehicles would be affected. “Part of the goal here is to put out this rule, and then the auto companies are going to come back to us,” said Wally Adeyomo, Deputy Secretary of the Treasury. “And then we will know which cars qualify.”
Automakers and EV experts have been anxiously awaiting guidance on the IRA’s foreign entities of concern provision. Adeyomo stressed that companies have been aware that these new rules would be coming ever since the law passed and have been making investments to ensure “that their cars would be able to qualify for this over the long term.”
Though it’s hard to fact check that claim, according to an EV supply chain database maintained by Turner and his students, at least 19 battery component factories have been announced in the U.S. and Canada since the passage of the IRA; none are yet operating, but automakers also have the option to buy components from U.S. trade partners. A report on the EV supply chain published by the International Energy Agency in 2022 notes that while China dominates cell component production, controlling 70% of capacity for cathodes and 85% of anodes, Japan and South Korea also had “considerable shares of the supply chain.”
Turner said it was conceivable that there will be models that qualify for the first phase of the rule beginning in January, which only applies to these battery components, but he was skeptical automakers would be able to continue qualifying in 2025, when the limits on critical minerals go into effect. “The further you get up the supply chain, the greater the exposure is to China,” he said. “It's not because China's got all of the critical minerals. It's that China has the processing facilities to turn those minerals into highly refined materials that are needed for the batteries.”
John Podesta, senior advisor to the president on clean energy innovation, said that Biden is “rewriting that story.” Officials pointed to a recent report from the Lawrence Berkeley National Laboratory, which found that the Salton Sea region in California has enough mineable lithium to support more than 375 million batteries for EVs. Turner’s database shows at least a dozen projects planned, rumored, or under construction to process minerals including lithium, cobalt, and graphite.
The guidance also raises questions about a $3.5 billion factory that Ford is building in Michigan to bring the production of safer, cheaper EV batteries to the U.S. The company is licensing technology from the Chinese company CATL, the world’s largest battery manufacturer, to produce batteries made of lithium, iron, and phosphate — which are more abundant than the cobalt and nickel used in the dominant batteries on the market. But the deal has come under scrutiny from House Republicans, who accuse CATL of having business ties to mining companies that use forced labor. Ford put construction on hold in September.
When asked about CATL, Deputy Secretary of Energy David Turk said the agency has not evaluated any individual company’s situation, but that they designed the licensing guidance to ”get at who has effective control in these kinds of situations.“
That could mean Ford is off the hook. Months ago, analysts told The Washington Post that the Chinese company will have little control over the Ford plant’s daily operations. “The way they structured this deal, they are keeping CATL at arm’s length as much as possible,” Sam Abuelsamid, head of e-mobility research at Guidehouse Insights, said.
The Biden administration is attempting to race forward on two sets of goals that are somewhat at odds with each other: speeding adoption of EVs while shifting their production away from China, thereby stimulating domestic industry and creating domestic jobs. When I spoke to Jane Nakano, a senior fellow at the Center for Strategic and International Studies, earlier this week, she said that if the Biden administration went with a strict 25% threshold for ownership, it could really accelerate automakers’ efforts to diversify sourcing away from China. “But that will take some time,” she added. “In the immediate future, many of the companies may simply try to compete without being able to access the consumer tax credit.”
Turner said that the question is not whether automakers can compete with low-cost EVs produced in China, but rather whether they can put out EVs that are cheaper than conventional cars on the market here.
“Once you get to the point that EVs are cheaper and we have a robust enough charging network that people aren't worried about running out of juice, I think that'll be the tipping point,” he said.
I should note that if you’re interested in this purely as a prospective consumer of an EV, the only thing you need to know is that your options to take advantage of the tax credit might be more limited come January. However, there is one weird trick to get around this and have a lot more options: Leasing. None of the rules around sourcing, assembly, or ownership apply to leased vehicles.

Two new reports out this week create a seemingly contradictory portrait of the country’s energy transition progress.
Two clean energy reports out this week offer seemingly contradictory snapshots of domestic solar and battery manufacturing. One, released Wednesday by the Rhodium Group’s Clean Investment Monitor, shows a distinct decline in investment going into U.S. factories to make more of these technologies. The other, released today by the trade group American Clean Power Association, shows staggering recent growth in production capacity.
So which is it? Is U.S. clean energy manufacturing booming or busting?
Maybe both.
The U.S. is suddenly producing more solar and batteries than ever before — enough to meet current domestic demand — so it makes sense that investment in new factories is starting to slow. At the same time, there’s a lot of room for growth in producing the upstream components that go into these technologies, but the U.S. is no longer as attractive a place to set up shop as it was over the past four years.
The U.S. saw 30 new utility-scale solar factories and 30 new battery factories come online last year alone, according to ACP. The country now has the capacity to meet average domestic demand for storage systems through 2030, and can produce enough solar panels to satisfy demand two times over.
In both industries, nearly all of that capacity has been added since 2022, when the Inflation Reduction Act created new subsidies for domestic manufacturing. The advanced manufacturing production tax credit incentivized not just solar and battery factories, but also all the production of components that go into these technologies, including solar and battery cells, polysilicon, wafers, and anodes. On top of these direct subsidies, the IRA generated demand for U.S.-made products by granting bonus tax credits for utility-scale solar and battery projects built with domestically produced parts.
“The policy definitely laid the right foundation for a lot of this investment to take place,” John Hensley, ACP’s senior vice president of markets and policy analysis, told me.
Trump’s One Big Beautiful Bill Act has changed the environment, however. The utility-scale wind and solar tax credits were supposed to apply through at least 2033, but now projects have to start construction by July 4, 2026 — just over a month from now — in order to claim them. Any of those projects that got started this year will also have to adhere to complex new sourcing rules prohibiting Chinese-made materials.
Now, dollars flowing into new U.S. solar factories appears to be on the decline. Investment fell 22% between the fourth quarter of last year and the first of 2026. Battery manufacturing investment dropped by 16%.
The reason investment is declining is not entirely because of OBBBA — it’s partly a function of the fact that a lot of the projects announced immediately after the IRA passed are entering operations, Hannah Hess, director of climate and energy at the Rhodium Group, told me.
Rhodium’s Clean Investment Monitor tracks two metrics, announcements and investment. Announcements are when a company says it’s building a new factory or expanding an existing one, usually with some kind of projected cost. Investments are an estimate of the actual dollars spent during a given quarter on facility construction, calculated based on the total project budget and the expected amount of time it will take to complete after breaking ground.
According to Rhodium’s data, the peak period for new solar manufacturing project announcements was the second half of 2022 through the first quarter of 2025. During that time, announcements averaged more than $2 billion per quarter. New solar factories announced this past quarter, by contrast, fell to about $350 million.
Since it can take a while to get steel in the ground, the peak period for investment was slightly later, with $13.5 billion invested between the second quarter of 2023 and the third quarter of 2025.
“What we were seeing in that post-IRA period was huge, almost unconstrained growth in that sector, and that’s not happening anymore,” Hess said.
Most of this growth occurred all the way downstream, at the final product assembly level — i.e. factories making solar and battery modules that still had to import many of the components that went into them. This was the “lowest hanging fruit” to bring to the U.S., Hensley, of ACP, told me, as the final assembly is the least technologically challenging part of the supply chain.
“These supply chains have momentum as they get going,” he said, “so as you establish those far downstream component manufacturing, you start to recruit all of the upstream manufacturing.” In other words, a solar cell manufacturer is far more likely to build in the U.S. if there’s a robust local market of module factories to buy the cells.
There’s evidence that’s still happening in spite of changes to the tax credit structure. The ACP report says that three solar cell factories came online between 2024 and today — one per year. If all of the additional factories that have been announced are built by 2030, the U.S. will have nearly enough capacity to meet all of its own demand for solar with domestic cells. Battery cell capacity is growing even faster, with three factories as of the end of 2025 and seven more expected to be complete by the end of this year, which will produce more than enough units to meet average annual demand.
It’s the next step up on the supply chain that spells trouble. For solar, that’s ingots and wafers, followed by polysilicon. Today, the only producer of ingots and wafers in the U.S. is a company called Corning. It produces enough to meet about 25% of current domestic solar cell production, but cell production will more than quadruple by the end of this year compared to last year, according to ACP. Similarly, we produce enough polysilicon to meet Corning’s current needs, but not enough to meet anticipated cell demand. The announced projects in the pipeline will not add much on either front.
For batteries, it’s the anodes and cathodes. There’s currently one factory in California producing cathodes and at least one more under construction, but as there is nothing else in the pipeline, the ACP report expects cell manufacturers to rely on imported cathodes for the foreseeable future. Anodes are the one bright spot — there’s one factory producing what’s known as active anode material factory in the U.S., and four more anticipated by the end of this year. Together, they have the potential to meet demand by 2028, according to ACP.
The question now is whether that snowball effect kicked off by the IRA will continue. “A lot has changed about the outlook for future demand after the One Big Beautiful Bill Act passed,” Hess said. “We have seen some more project cancellations and pauses in construction recently.”
Most recently, a company called Maxeon Solar Technologies canceled a $1 billion cell and module factory in New Mexico. The company had been “fighting for its life” since 2024, according to Canary Media. It’s also majority owned by a Chinese state-owned company. The
OBBBA was likely the nail in the coffin, as it penalizes solar developers who source panels from companies with Chinese ownership.
OBBBA also shortened the timeline for the wind and solar tax credits, while the Trump administration’s hostility to wind and solar permitting has made it more difficult for projects to get built before the credits expire. Hensley said the Trump administration’s hostility toward clean energy has added a lot of risk into the system, complicating final investment decisions for manufacturers.
On the flip side, tariffs have the potential to help some domestic producers. Duties on imports from countries such as Cambodia, India, and Vietnam, all major manufacturers of solar panels, “have made their exports to the U.S. almost prohibitive,” Lara Hayim, the head of solar research at BloombergNEF, told me in an email. “This sort of policy framework could continue to provide some protection for domestic manufacturers,” she said, but there are still plenty of countries with low enough tariffs that they will continue to serve the U.S. and compete with domestic manufacturers.
Hensley said that the Trump administration’s tariffs were a double edged sword. They can help domestic manufacturers, but not if they make all of the inputs into the product more expensive.
“That’s a problem with these blanket type of tariffs that aren’t really fine-tuned to target the behavior that you’d like to see,” he told me. “I think we’re seeing a lot of that push and pull and tension in the system at the moment.”
Between Trump’s tariffs and the OBBBA, there’s no doubt that the manufacturing boom sparked by the IRA is slowing. But Hensley is optimistic that the progress will continue. “We haven’t attracted all of the supply chain yet. It’s still a work in progress, but so far the signs are quite good.”
This week’s conversation is with Duncan Campbell of DER Task Force and it’s about a big question: What makes a socially responsible data center? Campbell’s expansive background and recent focus on this issue made me take note when he recently asked that question on X. Instead of popping up in his replies, I asked him to join me here in The Fight. So shall we get started?
Oh, as always, the following conversation was lightly edited for clarity.
Alright let’s start with the big question: What is a socially responsible data center?
So first, there’s water, which I think is pretty solvable.
Part of me thinks water is not even the right thing to be focusing on necessarily, and it’s surprising that it became at least for a while the center of the controversy around data centers.
I think there’s energy, which is mostly a don’t-raise-people’s-bills kind of thing. Or in extreme cases, actually reducing people’s access to energy.”
I think air pollution is another key. This is one of the biggest own-goals our [climate] space is making, because people are installing behind-the-meter power and we can talk about why they’re doing that, the shifting reasons, but the real shame in it is you really shouldn’t have to run those 24/7. If you’re building your own power plant, it should enable you to get a grid connection, because you’re bringing your own capacity and they can provide you firm service, and you should only have to run that gas plant 1% of the year, so air pollution is a non-issue. If only the grid and its institutions could get their act together, this is a no-brainer. But instead people run them 24/7.
There’s noise, which has been very misunderstood and bungled on a handful of well-known projects. That’s just a do-good engineering and site layout type of problem.
And then there’s other. Beyond the very concrete impacts of a data center, what else can it do for the community it's siting itself in? That’s going to be specific for every community.
There’s going to be a perspective that data centers are takers. They get tax incentives. They’re this big new thing. If data centers were to bring something compelling when [they’re] siting in communities, and it is specific to whatever they’re dealing with, maybe they’d be considered socially responsible.
I don’t think I have the master answer here. Everyone’s trying to figure it out.”
What do you hear from other folks in decarb and climate spaces when you ask this question? Do you hear people come up with solutions, or do they knock down the entire premise of the question — that there isn’t such a thing as a socially responsible data center?
You get both. You definitely get both. It depends on who you're talking to.
I can understand both sides of the equation here. There’s definitely solutions, first of all. I do think there’s a group of people whether it is in the energy world or the data center world or tech who would have this incredulous disbelief that anyone could not want what they’re doing. And that then, after being poked and prodded enough, transforms into a very elitist, almost pejorative explanation of everybody’s just NIMBYs.
I think that’s really unproductive. It kind of just throws gas on the fire.
But there’s a lot of people working on solutions, too. The non-firm grid service thing is just a huge opportunity. To be able to connect these sites to the grid in such a manner they either get curtailed some small amount of hours per year or they show up with accredited capacity, absolving them from curtailing. I mean, we can do that. It’s very doable.
The second question becomes, what are the forms of accredited capacity that can be deployed quickly? I think that’s where there’s a lot of cool stuff around VPPs and such. Sure, build a gas power plant, run it once or twice a year. If anything that’s good for a community — back-up power at grid scale.
There’s also other solutions. A really cool effort right now, former Tesla people building a purely solar and battery DC microgrid in New Mexico.
And there’s also a lot of inertia. The folks making decisions about data centers have been doing stuff a certain way for 20 years and it’s hard to change. The inertia within the culture combined with the enormous pressure to deploy just makes it less dynamic than one would hope.
On my end, I’ve been grappling with the issue of tax revenue. We’re seeing a declining amount of money for social services, things that can really help people for both personal and academic reasons. There's quite a bit a lot of people could say on that topic. At the same time, this is another form of industrial development. People are upset at the amount of resources going to this specific thing.
So when it comes to the data center boom in general, where do you stand on social cost-versus-benefit analysis?
That’s a good question. I’m not an expert. I’m mostly just someone who designs energy projects. But I can say where I’m at personally.
Yeah, but isn’t everyone in the energy space talking about data centers? Shouldn’t we all be thinking about this?
Of course. I’m not in a place to proclaim what is right but I’ll tell you where I’m at right now.
With any large-scale industrial build out it is tough relative to other technological changes that were simpler at the infrastructure layer. Like, the smartphone. Massive technological change but pretty straightforward in a lot of ways. But industrial buildout stresses real physical resources, so people have much more of an opinion of whether it’s worth it or not.
I’m pretty optimistic about AI generally. It’s very hand-wave-y. It’s hard to cite data or anything, because we’re talking about something that hasn’t happened yet, but I’m very optimistic about increasing the amount of intelligence we have access to per person on Earth.
A similar thing I think about is when everyone stopped getting lead poisoning all the time, we all jumped five IQ points and killed each other less. Intelligence is good. A lot of our story as a species is about increasing intelligence and learnings-per-person so we can do more. The idea that we would be able to synthesize it, operate it as a machine outside of our own bodies. It feels pretty inevitable.
There’s questions about what that [AI] will do to the economy and jobs, which is what people are really concerned about and is the case with any major technological change.
Are data centers being deployed at a rate and in a way that is responsible? Like, does it need to be this fast? That’s a question people ask and that’s in a way the question being posed by the moratoriums. They’re not saying let’s ban this forever. They’re saying, let’s take a breather. And I do understand that.
There’s a lot of good solutions that could just be pursued and it’s hard for me to separate my feelings about the current path data centers are taking from what I think is objectively right. We could just be doing way better.
On the energy front, what do you make of the way our energy mix — carbon versus renewables, our resilience — is headed? And where do you think we’re heading in five years?
For the energy and climate world, this is the real question. Data centers are a complicated thing but at the end of the day, for us, they’re a source of electricity demand.
From an electricity perspective, there’s been no growth for 20 years. So the theory of addressing climate change was, as the old stuff breaks we’ll replace it with new clean stuff. That was what we were doing, while saying, a lot of the old stuff we’ll keep around. We’ll layer on the new clean stuff.
It was always the case though that we could enter a new phase of electricity growth. Actually, five years ago, when the phrase “electrify everything” was coined, it explicitly became our goal! We were going to massively and rapidly grow the electricity system in order to switch industry, heating, and transport off of fossil fuels. That’s the right prescription, the right way to do it.
My understanding of it is that while this feels really big, because we haven’t grown in so long, compared to the challenge we were all talking about doing is not big at all. It increases the challenge by 15% or 20%. That’s meaningful. But it just seems like we should be able to do this.
From a climate perspective, as someone who’s been trying to do everything I can on it for a while now, I can’t help but feel a little dismayed that today the growth we’re experiencing is some tiny, tiny percentage of what we actually set out to do. And it’s causing chaos. We’re institutionally falling apart from a single percent of what our goals should be.
This is the time for the electrification case. We can all demonstrate this is possible over the next few years. I think confidence in the electricity system as our energy path can remain high. Or this utterly fails, where it’s really hard to imagine governments and businesses making any sincere attempt at a high electrification pathway.
Plus the week’s biggest development fights.
1. LaPorte County, Indiana — If you’re wondering where data centers are still being embraced in the U.S., look no further than the northwest Indiana city of LaPorte.
2. Cumberland County, New Jersey — A broader splashback against AI infrastructure is building in South Jersey.
3. Washington County, Oregon — Hillsboro, a data center hub in Oregon, is turning to a moratorium.
4. Champaign County, Ohio — We’re still watching the slow downfall of solar in Ohio and there’s no sign of it getting any better.
5. Essex County, New York — Man oh man, what’s going on with battery storage in rural pockets of the Empire State?
