“That’s going to cause confusion.”

It’s been nearly two years since the Inflation Reduction Act passed, and two of its programs designed to encourage home electrification and energy efficiency — worth a combined $8.8 billion — are still not operational.
The delay has already caused consternation among homeowners who can’t understand why they still don’t know when the rebates will be available or what they will cover. Now it’s becoming apparent that these programs could look quite different state by state.
This is, to some extent, by design. The rebates will be distributed by state governments, who must first apply to the Department of Energy for their share of the funding. Most states are still in the process of putting together their applications. The law laid out some rules for how these programs would work, e.g. which kinds of appliances and upgrades the rebates will subsidize and the maximum subsidy per appliance and per household. It also put restrictions on who could benefit from the programs, with most of the money earmarked for low- and moderate-income households. But it left plenty of flexibility for states to tailor the programs to their own needs.
That’s mostly a good thing. Many states already offer robust electrification and efficiency rebates, but their existing programs have major shortcomings. Apartment buildings, in particular, have been hard to reach — both because landlords have little incentive to make upgrades and because it’s much more complicated to retrofit a big apartment building than a single-family home. The IRA rebates create an opportunity to try and fill these kinds of gaps.
But the result is also, frankly, messy. The money is taking a long time to get out the door, and when it does the programs are going to be convoluted and challenging to communicate to consumers.This could turn out to be a missed opportunity for Biden. When the polling nonprofit Data for Progress asks voters about their greatest concerns relating to climate, they point to energy costs, pollution, and extreme weather. The IRA rebates are an opportunity to address these concerns, and 71% of voters support the programs — including majorities across party lines — according to the group’s surveys.
“Nobody would say that this rollout has been as fast as they would have wanted,” Sage Briscoe, the federal policy director for Rewiring America, told me. “But I’m hopeful that it's going to be really impactful, and at the end of the day, that’s the main thing.”
Information on how states are thinking about distributing the money is scarce. Some did extensive stakeholder engagement prior to submitting their applications and made their proposed plans public, while others are saving that process until after they apply. I combed through as much publicly available information as I could find and discovered a number of ways in which these rebate programs could diverge. The programs may go by different names in different states. Moreover, a heat pump discount in Maine may not exist in Rhode Island, or a family that qualifies for funding in Wisconsin may not have qualified had they lived in New Jersey.
Here are some of the big themes.
The challenge in understanding these programs starts with their most basic feature. What are they called?
One of the programs will provide point-of-sale rebates on specific appliances and upgrades such as heat pumps, insulation, or a new electric panel. This was originally called the High-Efficiency Electric Home Rebate Act, or HEEHRA. Some states have continued to use that acronym. Others have adopted the name the Home Electrification and Appliance Rebates, or HEAR. (For the sake of brevity, I’ll use HEAR.)
The other program, which is a bit more complicated, provides rebates based on the amount of energy a home retrofit project saves. For example, if a homeowner implements a bunch of improvements that will reduce their energy consumption by at least 20%, they could get up to $4,000 back, while upgrades that result in a 35% reduction are eligible for up to $8,000. This was originally called the HOPE for HOMES Act, and many states simply refer to it as HOMES. Others prefer the title Home Efficiency Rebates, or HER. (To make things more confusing, the Department of Energy refers to its two programs together as the Home Energy Rebates and also uses the acronym HER. For the sake of clarity, I’ll refer to this one as HOMES.)
Meanwhile, some states are funneling the money into their own pre-existing rebate programs or creating new programs with new names. For example, New York — the only state to have received funding under the IRA rebate programs so far— will distribute at least some of the HEAR money through its Empower+ program, which already helps low- and moderate-income households save energy. The state will be able to expand the program’s offerings to include paying for electrical upgrades needed to install heat pumps or induction stoves. Vermont wants to allocate most of the HOMES funding to its Weatherization Assistance Program, which is an older, federally funded, state-implemented efficiency program for low-income households. New Jersey is considering putting most of the funding from both pots toward a new program called M-RISE.
Ultimately, this could mean that many people who apply for or receive these rebates will have no idea that they’re benefiting from Biden’s Inflation Reduction Act.
“That was baked in the cake the way the law was written,” Andy Frank, the founder of the home electrification company Sealed, told me. He said he thinks the bigger communication challenge will be when the first few states start launching their programs. Biden officials may take the opportunity to do a victory lap, inviting national press. People in other states may see the news and think they can get rebates too. “That’s going to cause confusion,” he said.
Briscoe acknowledged the branding challenge but said it was not the most important part of the legislation. “The most important thing is getting families the help that they need, and I think that’s rightfully where the emphasis has been,” she told me.
Congress included a long list of technologies that would be eligible for discounts under the HEAR program: Heat pump space heaters, heat pump water heaters, heat pump clothes dryers, electric stoves, electric panels, electric wiring, insulation, air sealing, and ventilation systems.
While it seems that most states plan to copy and paste the whole list into their plans, a few are narrowing it down. Maine, for example, has proposed offering rebates only for heat pumps, plus electric wiring and panel upgrades if needed. Its draft strategic plan from January says that the state has alternative funding streams to sustain its existing programs for water heaters and insulation, and that the other appliances, like stoves and clothes dryers, “have less impact on home energy costs and carbon emissions.”
Rhode Island, on the other hand, may not allocate any of the funding for heat pumps. The state conducted a “gap analysis” to identify which of the technologies have the least funding support under its existing programs and determined that stoves, clothes dryers, electric panels, and wiring were the best use of the HEAR funds. That doesn’t mean Rhode Islanders wouldn’t be able to get rebates for heat pumps — the state energy office offers incentives, as do all of its utilities. It just means they wouldn’t be able to get more funding on top of what’s already offered.
Wisconsin, which is further behind these Northeast states in promoting electrification, is opting to make all of the technologies eligible. Though narrowing the list would extend the budget for each one, state officials noted, it would also “preclude the state from accelerating market adoption for those upgrades.”
Congress restricted HEAR program funding to low-income households, defined as those making less than 80% of the area median income, and moderate-income households, or those making between 80% and 150% of the area median income. The HOMES program is not income-restricted, though states were instructed to offer higher rebates for low-income households.
There’s going to be a lot of variation between states regarding how much funding they dedicate to each income bracket. But there also may be some variation in the types of buildings that are eligible.
Maine has proposed dedicating 100% of the funding under the HOMES program and much of the funding under HEAR to multifamily buildings. For the HEAR program, it might also prioritize subsidizing heat pump retrofits in manufactured housing, formerly referred to as “mobile homes.” That means if you’re a single family homeowner in Maine, you probably won’t benefit from the program — although Maine already has extensive subsidies for single-family homes and has completed more than 100,000 heat pump retrofits since 2019.
“They're taking this funding to try and move beyond that section of housing and open up robust programs for areas where they still have really high need,” said Briscoe.
New Jersey has proposed a similar approach, dedicating 100% of HOMES funding and 85% of HEAR funding to multifamily buildings in low-income neighborhoods. The remaining 15% will go toward an existing state program called Comfort Partners that subsidizes energy efficiency measures to expand its offerings to heat pumps, electrical panels, wiring, and water heaters.
Sealed and Rewiring America are both working on tools to help consumers and contractors navigate all of this confusion. Frank told me Sealed was developing software for contractors that will help them determine customer eligibility and calculate total savings at the point of sale, and then process the rebate paperwork as quickly and easily as possible. Rewiring America is building what it intends to be a user-friendly calculator in which a homeowner will be able to enter their zip code and income and get information about all of the programs they are eligible for, including state, local, and utility-run offerings.
Or at least Californians are. Dozens have written to the California Energy Commission to ask when the rebates will be available, whether they will qualify, or to express their frustration with how long it’s taking to get the program up and running.
Consider the following comment submitted in April by Kristen Talley, a homeowner who wants to replace her gas furnace with an electric heat pump. “We’d hoped to do the project last fall … and we can’t proceed until the rebates are available,” she wrote. “Please establish criteria and make applications available NOW!!! It’s crazy that it's taken this long!”
Richard Pellin, a 77-year-old retiree who does not have enough income to qualify for the tax credits, wrote that he wants to install a new heat pump system so that he can have air conditioning. “We suffered badly last year from the summer heat … Waiting until the state programs are ready to issue rebates would cause us to suffer longer,” he said. He implored the commission to allow the rebates to be claimed retroactively, warning that otherwise there might be “a surge of activity when rebates are approved” that will tax supply chains and labor and cause further delays. (The Department of Energy has specified that the HEAR rebates cannot be claimed retroactively, but it may be possible for the HOMES rebates.)
Some of this frustration is misplaced. California submitted its application for the HEAR program in January and is waiting on the Department of Energy to approve it. In the meantime, it may even be possible that Talley and Pellin are eligible for existing California rebate programs, though discounts through those are significantly lower.
Another public comment from Richard Bailey had the subject line: “Time is of the essence.” Bailey warned that the rebates could be “canceled, denied, delayed, etc” if Trump was elected. “Much is at risk. Do not delay,” he wrote.
I asked Briscoe how much of a risk this was. She said it would require an act of Congress to cancel the programs — in other words, it’s not something Trump could do on day one. Even then, money that’s already been awarded to states cannot be clawed back. Fifteen states have already submitted their applications, and are expected to receive funding by the end of the year.
“Hopefully, we can get a lot of these applications in and processed before any new administration were to take over,” said Briscoe.

In practice, direct lithium extraction doesn’t quite make sense, but 2026 could its critical year.
Lithium isn’t like most minerals.
Unlike other battery metals such as nickel, cobalt, and manganese, which are mined from hard-rock ores using drills and explosives, the majority of the world’s lithium resources are found in underground reservoirs of extremely salty water, known as brine. And while hard-rock mining does play a major role in lithium extraction — the majority of the world’s actual production still comes from rocks — brine mining is usually significantly cheaper, and is thus highly attractive wherever it’s geographically feasible.
Reaching that brine and extracting that lithium — so integral to grid-scale energy storage and electric vehicles alike — is typically slow, inefficient, and environmentally taxing. This year, however, could represent a critical juncture for a novel process known as Direct Lithium Extraction, or DLE, which promises to be faster, cleaner, and capable of unlocking lithium across a wider range of geographies.
The traditional method of separating lithium from brine is straightforward but time-consuming. Essentially, the liquid is pumped through a series of vast, vividly colored solar evaporation ponds that gradually concentrate the mineral over the course of more than a year.
It works, but by the time the lithium is extracted, refined, and ready for market, both the demand and the price may have shifted significantly, as evidenced by the dramatic rise and collapse of lithium prices over the past five years. And while evaporation ponds are well-suited to the arid deserts of Chile and Argentina where they’re most common, the geology, brine chemistry, and climate of the U.S. regions with the best reserves are generally not amenable to this approach. Not to mention the ponds require a humongous land footprint, raising questions about land use and ecological degradation.
DLE forgoes these expansive pools, instead pulling lithium-rich brine into a processing unit, where some combination of chemicals, sorbents, or membranes isolate and extricate the lithium before the remaining brine gets injected back underground. This process can produce battery-grade lithium in a matter of hours or days, without the need to transport concentrated brine to separate processing facilities.
This tech has been studied for decades, but aside from a few Chinese producers using it in combination with evaporation ponds, it’s largely remained stuck in the research and development stage. Now, several DLE companies are looking to build their first commercial plants in 2026, aiming to prove that their methods can work at scale, no evaporation ponds needed.
“I do think this is the year where DLE starts getting more and more relevant,” Federico Gay, a principal lithium analyst at Benchmark Mineral Intelligence, told me.
Standard Lithium, in partnership with oil and gas major Equinor, aims to break ground this year on its first commercial facility in Arkansas’s lithium-rich Smackover Formation, while the startup Lilac Solution also plans to commence construction on a commercial plant at Utah’s Great Salt Lake. Mining giant Rio Tinto is progressing with plans to build a commercial DLE facility in Argentina, which is already home to one commercial DLE plant — the first outside of China. That facility is run by the French mining company Eramet, which plans to ramp production to full capacity this year.
If “prices are positive” for lithium, Gay said, he expects that the industry will also start to see mergers and acquisitions this year among technology providers and larger corporations such as mining giants or oil and gas majors, as “some of the big players will try locking in or buying technology to potentially produce from the resources they own.” Indeed, ExxonMobil and Occidental Petroleum are already developing DLE projects, while major automakers have invested, too.
But that looming question of lithium prices — and what it means for DLE’s viability — is no small thing. When EV and battery storage demand boomed at the start of the decade, lithium prices climbed roughly 10-fold through 2022 before plunging as producers aggressively ramped output, flooding the market just as EV demand cooled. And while prices have lately started to tick upward again, there’s no telling whether the trend will continue.
“Everyone seems to have settled on a consensus view that $20,000 a tonne is where the market’s really going to be unleashed,” Joe Arencibia, president of the DLE startup Summit Nanotech, told me, referring to the lithium extraction market in all of its forms — hard rock mining, traditional brine, and DLE. “As far as we’re concerned, a market with $14,000, $15,000 a tonne is fine and dandy for us.”
Lilac Solutions, the most prominent startup in the DLE space, expects that its initial Utah project — which will produce a relatively humble 5,000 metric tons of lithium per year — will be profitable even if lithium prices hit last year’s low of $8,300 per metric ton. That’s according to the company’s CEO Raef Sully, who also told me that because Utah’s reserves are much lower grade than South America’s, Lilac could produce lithium for a mere $3,000 to $3,500 in Chile if it scaled production to 15,000 or 20,000 metric tons per year.
What sets Lilac apart from other DLE projects is its approach to separating lithium from brine. Most companies are pursuing adsorption-based processes, in which lithium ions bind to an aluminum-based sorbent, which removes them from surrounding impurities. But stripping the lithium from the sorbent generally requires a good deal of freshwater, which is not ideal given that many lithium-rich regions are parched deserts.
Lilac’s tech relies on an ion-exchange process in which small ceramic beads selectively capture lithium ions from the brine in their crystalline structure, swapping them for hydrogen ions. “The crystal structure seems to have a really strong attraction to lithium and nothing else,” Sully told me. Acid then releases the concentrated lithium. When compared with adsorption-based tech, he explained, this method demands far fewer materials and is “much more selective for lithium ions versus other ions,” making the result purer and thus cheaper to process into a battery-grade material.
Because adsorption-based DLE is already operating commercially and ion-exchange isn’t, Lilac has much to prove with its first commercial facility, which is expected to finalize funding and begin construction by the middle of this year.
Sully estimates that Lilac will need to raise around $250 million to build its first commercial facility, which has already been delayed due to the price slump. The company’s former CEO and current CTO Dave Snydacker told me in 2023 that he expected to commence commercial operations by the end of 2024, whereas now the company plans to bring its Utah plant online at the end of 2027 or early 2028.
“Two years ago, with where the market was, nobody was going to look at that investment,” Sully explained, referring to its commercial plant. Investors, he said, were waiting to see what remained after the market bottomed out, which it now seems to have done. Lilac is still standing, and while there haven’t yet been any public announcements regarding project funding, Sully told me he’s confident that the money will come together in time to break ground in mid-2026.
It also doesn’t hurt that lithium prices have been on the rise for a few months, currently hovering around $20,000 per tonne. Gay thinks prices are likely to stabilize somewhere in this range, as stakeholders who have weathered the volatility now have a better understanding of the market.
At that price, hard rock mining would be a feasible option, though still more expensive than traditional evaporation ponds and far above what DLE producers are forecasting. And while some mines operated at a loss or mothballed their operations during the past few years, Gay thinks that even if prices stabilize, hard-rock mines will continue to be the dominant source of lithium for the foreseeable future due to sustained global investment across Africa, Brazil, Australia, and parts of Asia. The price may be steeper, but the infrastructure is also well-established and the economics are well-understood.
“I’m optimistic and bullish about DLE, but probably it won’t have the impact that it was thought about two or three years ago,” Gay told me, as the hype has died down and prices have cooled from their record high of around $80,000 per tonne. By 2040, Benchmark forecasts that DLE will make up 15% to 20% of the lithium market, with evaporation ponds continuing to be a larger contributor for the next decade or so, primarily due to the high upfront costs of DLE projects and the time required for them to reach economies of scale.
On average, Benchmark predicts that this tech will wind up in “the high end of the second quartile” of the cost curve, making DLE projects a lower mid-cost option. “So it’s good — not great, good. But we’ll have some DLE projects in the first quartile as well, so competing with very good evaporation assets,” Gay told me.
Unsurprisingly, the technology companies themselves are more bullish on their approach. Even though Arencibia predicts that evaporation ponds will continue to be about 25% cheaper, he thinks that “the majority of future brine projects will be DLE,” and that DLE will represent 25% or more of the future lithium market.
That forecast comes in large part because Chile — the world’s largest producer of lithium from brine — has stated in its National Lithium Strategy that all new projects should have an “obligatory requirement” to use novel, less ecologically disruptive production methods. Other nations with significant but yet-to-be exploited lithium brine resources, such as Bolivia, could follow suit.
Sully is even more optimistic, predicting that as lithium demand grows from about 1.5 million metric tons per year to around 3.5 million metric tons by 2035, the majority of that growth will come from DLE. “I honestly believe that there will be no more hard rock mines built in Australia or the U.S.,” he said, telling me that in ten years time, half of our lithium supply could “easily” come from DLE.
As a number of major projects break ground this year and the big players start consolidating, we’ll begin to get a sense of whose projections are most realistic. But it won’t be until some of these projects ramp up commercial production in the 2028 to 2030 timeframe that DLE’s market potential will really crystalize.
“If you’re not a very large player at the moment, I think it’s very difficult for you to proceed,” Sully told me, reflecting on how lithium’s price shocks have rocked the industry. Even with lithium prices ticking precariously upwards now, the industry is preparing for at least some level of continued volatility and uncertainty.
“Long term, who knows what [prices are] going to be,” Sully said. “I’ve given up trying to predict.”
A chat with CleanCapital founder Jon Powers.
This week’s conversation is with Jon Powers, founder of the investment firm CleanCapital. I reached out to Powers because I wanted to get a better understanding of how renewable energy investments were shifting one year into the Trump administration. What followed was a candid, detailed look inside the thinking of how the big money in cleantech actually views Trump’s war on renewable energy permitting.
The following conversation was lightly edited for clarity.
Alright, so let’s start off with a big question: How do investors in clean energy view Trump’s permitting freeze?
So, let’s take a step back. Look at the trend over the last decade. The industry’s boomed, manufacturing jobs are happening, the labor force has grown, investments are coming.
We [Clean Capital] are backed by infrastructure life insurance money. It’s money that wasn’t in this market 10 years ago. It’s there because these are long-term infrastructure assets. They see the opportunity. What are they looking for? Certainty. If somebody takes your life insurance money, and they invest it, they want to know it’s going to be there in 20 years in case they need to pay it out. These are really great assets – they’re paying for electricity, the panels hold up, etcetera.
With investors, the more you can manage that risk, the more capital there is out there and the better cost of capital there is for the project. If I was taking high cost private equity money to fund a project, you have to pay for the equipment and the cost of the financing. The more you can bring down the cost of financing – which has happened over the last decade – the cheaper the power can be on the back-end. You can use cheaper money to build.
Once you get that type of capital, you need certainty. That certainty had developed. The election of President Trump threw that into a little bit of disarray. We’re seeing that being implemented today, and they’re doing everything they can to throw wrenches into the growth of what we’ve been doing. They passed the bill affecting the tax credits, and the work they’re doing on permitting to slow roll projects, all of that uncertainty is damaging the projects and more importantly costs everyone down the road by raising the cost of electricity, in turn making projects more expensive in the first place. It’s not a nice recipe for people buying electricity.
But in September, I went to the RE+ conference in California – I thought that was going to be a funeral march but it wasn’t. People were saying, Now we have to shift and adjust. This is a huge industry. How do we get those adjustments and move forward?
Investors looked at it the same way. Yes, how will things like permitting affect the timeline of getting to build? But the fundamentals of supply and demand haven’t changed and in fact are working more in favor of us than before, so we’re figuring out where to invest on that potential. Also, yes federal is key, but state permitting is crucial. When you’re talking about distributed generation going out of a facility next to a data center, or a Wal-Mart, or an Amazon warehouse, that demand very much still exists and projects are being built in that middle market today.
What you’re seeing is a recalibration of risk among investors to understand where we put our money today. And we’re seeing some international money pulling back, and it all comes back to that concept of certainty.
To what extent does the international money moving out of the U.S. have to do with what Trump has done to offshore wind? Is that trade policy? Help us understand why that is happening.
I think it’s not trade policy, per se. Maybe that’s happening on the technology side. But what I’m talking about is money going into infrastructure and assets – for a couple of years, we were one of the hottest places to invest.
Think about a European pension fund who is taking money from a country in Europe and wanting to invest it somewhere they’ll get their money back. That type of capital has definitely been re-evaluating where they’ll put their money, and parallel, some of the larger utility players are starting to re-evaluate or even back out of projects because they’re concerned about questions around large-scale utility solar development, specifically.
Taking a step back to something else you said about federal permitting not being as crucial as state permitting–
That’s about the size of the project. Huge utility projects may still need federal approvals for transmission.
Okay. But when it comes to the trendline on community relations and social conflict, are we seeing renewable energy permitting risk increase in the U.S.? Decrease? Stay the same?
That has less to do with the administration but more of a well-structured fossil fuel campaign. Anti-climate, very dark money. I am not an expert on where the money comes from, but folks have tried to map that out. Now you’re even seeing local communities pass stuff like no energy storage [ordinances].
What’s interesting is that in those communities, we as an industry are not really present providing facts to counter this. That’s very frustrating for folks. We’re seeing these pass and honestly asking, Who was there?
Is the federal permitting freeze impacting investment too?
Definitely.
It’s not like you put money into a project all at once, right? It happens in these chunks. Let’s say there’s 10 steps for investing in a project. A little bit of money at step one, more money at step two, and it gradually gets more until you build the project. The middle area – permitting, getting approval from utilities – is really critical to the investments. So you’re seeing a little bit of a pause in when and how we make investments, because we sometimes don’t know if we’ll make it to, say, step six.
I actually think we’ll see the most impact from this in data center costs.
Can you explain that a bit more for me?
Look at northern Virginia for a second. There wasn’t a lot of new electricity added to that market but you all of the sudden upped demand for electricity by 20 percent. We’re literally seeing today all these utilities putting in rate hikes for consumers because it is literally a supply-demand question. If you can’t build new supply, it's going to be consumers paying for it, and even if you could build a new natural gas plant – at minimum that will happen four-to-six years from now. So over the next four years, we’ll see costs go up.
We’re building projects today that we invested in two years ago. That policy landscape we invested in two years ago hasn’t changed from what we invested into. But the policy landscape then changed dramatically.
If you wipe out half of what was coming in, there’s nothing backfilling that.
Plus more on the week’s biggest renewables fights.
Shelby County, Indiana – A large data center was rejected late Wednesday southeast of Indianapolis, as the takedown of a major Google campus last year continues to reverberate in the area.
Dane County, Wisconsin – Heading northwest, the QTS data center in DeForest we’ve been tracking is broiling into a major conflict, after activists uncovered controversial emails between the village’s president and the company.
White Pine County, Nevada – The Trump administration is finally moving a little bit of renewable energy infrastructure through the permitting process. Or at least, that’s what it looks like.
Mineral County, Nevada – Meanwhile, the BLM actually did approve a solar project on federal lands while we were gone: the Libra energy facility in southwest Nevada.
Hancock County, Ohio – Ohio’s legal system appears friendly for solar development right now, as another utility-scale project’s permits were upheld by the state Supreme Court.
