A practical guide to using the climate law to get cheaper solar panels, heat pumps, and more.

Today marks the one year anniversary of the Inflation Reduction Act, the biggest investment in tackling climate change the United States has ever made. The law consists of dozens of subsidies to help individuals, households, and businesses adopt clean energy technologies. Many of these solutions will also help people save money on their energy bills, reduce pollution, and improve their resilience to disasters.
But understanding how much funding is available for what, and how to get it, can be pretty confusing. Many Americans are not even aware that these programs exist. A poll conducted by The Washington Post and the University of Maryland in late July found that about 66% of Americans say they have heard “little” or “nothing at all” about the law’s incentives for installing rooftop solar panels, and 77% have heard little or nothing about subsidies for heat pumps. This tracks similar polling that Heatmap conducted last winter, suggesting not much has changed since then.
Below is Heatmap’s guide to the IRA’s incentives for cutting your carbon footprint at home. If you haven’t heard much about how the IRA can help you decarbonize your life, this guide is for you. If you have heard about the available subsidies, but aren’t sure how much they are worth or where to begin, I’ll walk you through it. (And if you’re looking for information about the electric vehicle tax credit, my colleague at Heatmap Robinson Meyer has you covered with this buyer’s guide.)
Get one great climate story in your inbox every day:
There’s funding for almost every solution you can think of to make your home more energy efficient and reduce your fossil fuel use, whether you want to install solar panels, insulate your attic, replace your windows, or buy electric appliances. If you need new wiring or an electrical panel upgrade before you can get heat pumps or solar panels, there’s some money available for that, too.
The IRA created two types of incentives for home energy efficiency improvements: Unlimited tax credits that will lower the amount you owe when you file your taxes, and $8.8 billion in rebates that function as up-front discounts or post-installation refunds on equipment and services.
The tax credits are available now, but the rebates are not. The latter will be administered by states, which must apply for funding and create programs before the money can go out. The Biden administration began accepting applications at the end of July and expects states to begin rolling out their programs later this year or early next.
The home tax credits are available to everyone that owes taxes. The rebates, however, will have income restrictions (more on this later).
“The Inflation Reduction Act is not a limited time offer,” according to Ari Matusiak, the CEO of the nonprofit advocacy group Rewiring America. The rebate programs will only be available until the money runs out, but, again, none of them have started yet. Meanwhile, there’s no limit on how many people can claim the tax credits, and they’ll be available for at least the next decade. That means you don’t need to rush and replace your hot water heater if you have one that works fine. But when it does break down, you’ll have help paying for a replacement.
You might want to hold off on buying new appliances or getting insulation — basically any improvements inside your house. There are tax credits available for a lot of this stuff right now, but you’ll likely be able to stack them with rebates in the future.
However, if you’re thinking of installing solar panels on your roof or getting a backup battery system, there’s no need to wait. The rebates will not cover those technologies.
A few other caveats: There’s a good chance your state, city, or utility already offers rebates or other incentives for many of these solutions. Check with your state’s energy office or your utility to find out what’s available. Also, it can take months to get quotes and line up contractors to get this kind of work done. If you want to be ready when the rebates hit, it’s probably a good idea to do some of the legwork now.
If you do nothing else this year, consider getting a professional home energy audit. This will cost several hundred dollars, depending on where you live, but you’ll be able to get 30% off or up to $150 back under the IRA’s home improvement tax credit. Doing an audit will help you figure out which solutions will give you the biggest bang for your buck, and how to prioritize them once more funding becomes available. The auditor might even be able to explain all of the existing local rebate programs you’re eligible for.
The Internal Revenue Service will allow you to work with any home energy auditor until the end of this year, but beginning in 2024, you must hire an auditor with specific qualifications in order to claim the credit.
Let’s start with what’s inside your home. In addition to an energy audit, the Energy Efficiency Home Improvement Credit offers consumers 30% off the cost (after any other subsidies, and excluding labor) of Energy Star-rated windows and doors, insulation, and air sealing.
There’s a maximum amount you can claim for each type of equipment each year:
$600 for windows
$500 for doors
$1,200 for air sealing and insulation
The Energy Efficiency Home Improvement Credit also covers heat pumps, heat pump water heaters, and electrical panel upgrades, including the cost of installation for those systems. You can get:
$2,000 for heat pumps
$600 for a new electrical panel
Yes, homeowners can only claim up to $3,200 per year under this program until 2032.
Also, one downside to the Energy Efficiency Home Improvement Credit is that it does not carry over. If you spend enough on efficiency to qualify for the full $3,200 in a given year, but you only owe the federal government $2,000 for the year, your bill will go to zero and you will miss out on the remaining $1,200 credit. So it could be worth your while to spread the work out.
The other big consumer-oriented tax credit, the Residential Clean Energy Credit, offers homeowners 30% off the cost of solar panels and solar water heaters. It also covers battery systems, which store energy from the grid or from your solar panels that you can use when there’s a blackout, or sell back to your utility when the grid needs more power.
The subsidy has no limits, so if you spend $35,000 on solar panels and battery storage, including labor, you’ll be eligible for the full 30% refund, or $10,500. The credit can also be rolled over, so if your tax liability that year is only $5,000, you’ll be able to claim more of it the following year, and continue doing so until you’ve received the full value.
Geothermal heating systems are also covered under this credit. (Geothermal heat pumps work similarly to regular heat pumps, but they use the ground as a source and sink for heat, rather than the ambient air.)
Here’s what we know right now. The IRA funded two rebate programs. One, known as the Home Energy Performance-Based Whole House Rebates, will provide discounts to homeowners and landlords based on the amount of energy a home upgrade is predicted to save.
Congress did not specify which energy-saving measures qualify — that’s something state energy offices will decide when they design their programs. But it did cap the total amount each household could receive, based on income. For example, if your household earns under 80% of the area median income, and you make improvements that cut your energy use by 35%, you’ll be eligible for up to $8,000. If your household earns more than that, you can get up to $4,000.
There’s also the High-Efficiency Electric Home Rebate Program, which will provide discounts on specific electric appliances like heat pumps, an induction stove, and an electric clothes dryer, as well as a new electrical panel and wiring. Individual households can get up to $14,000 in discounts under this program, although there are caps on how much is available for each piece of equipment. This money will only be available to low- and moderate-income households, or those earning under 150% of the area median income.
Renters with a household income below 150% of the area median income qualify for rebates on appliances that they should be able to install without permission from their landlords, and that they can take with them if they move. For example, portable appliances like tabletop induction burners, clothes dryers, and window-unit heat pumps are all eligible for rebates.
It’s also worth noting that there is a lot of funding available for multifamily building owners. If you have a good relationship with your landlord, you might want to talk to them about the opportunity to make lasting investments in their property. Under the performance-based rebates program, apartment building owners can get up to $400,000 for energy efficiency projects.
For the most part, yes. But the calculus gets tricky when it comes to heat pumps.
Experts generally agree that no matter where you live, switching from an oil or propane-burning heating system or electric resistance heaters to heat pumps will lower your energy bills. Not so if you’re switching over from natural gas.
Electric heat pumps are three to four times more efficient than natural gas heating systems, but electricity is so much more expensive than gas in some parts of the country that switching from gas to a heat pump can increase your overall bills a bit. Especially if you also electrify your water heater, stove, and clothes dryer.
That being said, Rewiring America estimates that switching from gas to a heat pump will lower bills for about 60% of households. Many utilities offer tools that will help you calculate your bills if you make the switch.
The good news is that all the measures I’ve discussed in this article are expected to cut carbon emissions and pollution, even if most of your region’s electricity still comes from fossil fuels. For some, that might be worth the monthly premium.
Tax Credit #1 offers 30% off the cost of energy audits, windows, doors, insulation, air sealing, heat pumps, electrical panels, with a $3200-per-year allowance and individual item limits.
Tax Credit #2 offers 30% off the cost of solar panels, solar water heaters, batteries, and geothermal heating systems.
Rebate Program #1 will offer discounts on whole-home efficiency upgrades depending on how much they reduce your energy use, with an $8,000 cap for lower-income families and a $4,000 cap for everyone else.
Rebate Program #2 is only for low- and moderate- income households, and will offer discounts on specific electric appliances, with a $14,000 cap.

Jason Fenske loved his Lucid. Or at least, the idea of it.
Fenske is the proprietor of the influential Engineering Explained channel on YouTube, which digs into the mechanical minutiae of both combustion and electric vehicles. While he regularly test-drives all sorts of cars, Fenske last year bought himself a Lucid Air, the big, beautiful sedan from the California EV startup.
The choice was no surprise. Fenske called the Air “one of the most impressive feats of engineering in the automotive world.” Technologically, it is indeed a car without compromise. Despite delivering 600-plus horsepower and a 0-60 mph time of barely more than 3 seconds, it was also the most efficient car in America, a fact that helped push its driving range above 400 miles per charge. But after a year of Fenske’s Air struggling with seemingly incurable software glitches, the company bought back his car and gave him a long-term loan of the Gravity, its new electric SUV. When that, too, suffered software bugs, he finally moved on to a Ford.
The episode encapsulates what has been a trying time for the automaker. Alongside Tesla and Rivian, Lucid looked to be the third successful EV startup to spring out of California. Tesla, once it overcame the trials of “manufacturing hell” to produce the Model 3 and Model Y, seized control of the American EV market and has yet to let go. Rivian, buoyed through the bad years by investments from the likes of Volkswagen and Amazon, appears poised to reach a sustainable future now that the more affordable R2 is out and thriving. Lucid, though, is stuck in an earlier stage in startup evolution — reportedly burning through cash as it struggles with both the software side of its vehicles and with the state of the U.S. EV market. The mood grew so grim this summer that the company announced a full operational reset to try to restore investor confidence, which included CEO Peter Rawlinson, formerly the man in charge of the Tesla Model S, stepping down.
Things started off much more promising in 2021, when the Air established Lucid as the efficiency nerd’s EV. Today, the rear-wheel-drive version gets the equivalent of 146 miles per gallon — tops in the U.S., and good enough for the Air to get 420 miles of range. The most expensive Air, with a supersized battery to match, delivers an eye-popping figure of 512 miles.
The obvious next step for the American market is to build an SUV, which Lucid has done with the Gravity. We tested it this past weekend in a seven-seat configuration, ferrying five people and three dogs up to Oak Glen, California, the mountain town of apple orchards and pumpkin patches where Angelenos come to cosplay autumn. (Bibi, one of the four-legged passengers who doesn’t care for cars, loved the Lucid). Despite its length, which gives it the proportions of a svelte minivan, the Gravity’s ample power makes it drive like a lighter vehicle. And despite its size, the Lucid’s efficiency obsession gives the car 400-plus miles of range, allowing us to drive a three-hour round trip and still have half the battery capacity left over. I can’t tell you how luxurious that feels compared to everyday life in a standard-range Tesla Model 3.
Inside, the Gravity is truly deluxe and inviting. Where Tesla embraced a fully minimalist interior and Rivian projects more of an REI, gentrified outdoorsy aesthetic, Lucid tilts more toward being the electric black car. The sprawling curved screen across the dashboard and secondary large touchscreen in the central console, combined with the elegant approach to its UI, is just so much more sophisticated than what you’d see in a legacy carmaker’s EV.
The setup offers a refined way to use all the car’s basic functions like climate, music, and navigation, as well as search for charging stations and view all of the car’s energy and efficiency stats. The array of settings and options allows an EV enthusiast to tweak a thousand things about their car. Take charge planning on road trips, a sore spot I often gripe about: In the Lucid, a bevy of options lets you select and deselect whichever charging networks you want, tell the computer whether to prioritize total time versus number of charging stops, and lots more. Then there are the premium extras meant to justify the Gravity’s price, which starts at $80,000 and rises from there. Wellness and relaxation programs can take over the digital displays and lighting, transforming the cabin into a little spa on wheels for as long as you’d like. The car simply feels like Silicon Valley affluence.
Within that user experience lies the problem, though. Lucid’s EVs are unquestionably mechanically excellent. But in the age of the software-defined car, all the software has to be excellent, too. Fenske’s Air wasn’t the only Lucid beset by bugs. This is an unavoidable fact of life in the 21st century — Tesla and Rivian have certainly had their share — but Lucid appears to have struggled more to cleanse them. Even my test unit would erroneously flash a momentary warning while I was rolling down the freeway (close latch before driving!) that disappeared just as quickly. It made no real difference to the driving experience, yet it’s one of those tiny glitches that saps one’s confidence in a car whose software is also responsible for keeping you safe.
Set aside software woes, and the timeline is troublesome for Lucid, too. Tesla established a pattern for EV startups: it built the very expensive Model S and X first, making just enough revenue from those pricey halo cars to survive until it could build the more affordable Model 3 and Y and generate a reliable revenue stream. Rivian took a similar path, selling R1 pickups and SUVs that cost $70,000, and sometimes much more, before introducing the R2 this year. Lucid’s smaller and cheaper EVs would be called the Cosmos and Earth, but we’ve yet to see those vehicles, and they won’t arrive until at least next year. When they do show up, they’ll have to compete with an improving set of luxury EVsfrom the likes of BMW and Mercedes-Benz.
Once those $50,000 Lucids exist, far more drivers will be exposed to all the things that the brand does right. And maybe — as long as there’s enough investment cash to get there — that will establish Lucid as a brand that is here to stay. Until then, the sticker price of these dream machines means that Lucid is competing in a small slice of an already small market, since not even a year of expensive gas has been enough to tip Americans toward EVs for good.

My colleague Emily Pontecorvo has a fascinating story today about Net Power, an energy and power development company whose technology once seemed key to decarbonizing the country’s electricity grid.
When Net Power went public in 2023, it was working on a natural gas-burning power plant that would generate little to no emissions in part by using carbon capture and storage. Its invention seemed to have big implications, and not just for the company’s bottom line: Back then, the Environmental Protection Agency was drafting climate rules that would have required new natural gas plants built in the 2030s to capture their carbon dioxide emissions. Net Power’s technology seemed like one of the best available ways to meet that standard.
Cut to 2026, and the world looks different. Thanks to the artificial intelligence boom, electricity demand is surging. But Net Power hasn’t successfully commercialized its proprietary power plant technology. Even if it had, few companies are willing to pay the high premium required by Net Power’s technology, especially when cheaper options are available. And the government certainly isn’t going to require it. Emily’s story reveals what happened next.
When I helped start Heatmap more than three years ago, I never thought I would write this much about data centers. I believed that electricity demand growth was inevitable, sure, and I thought the U.S. power grid had to expand for the country to decarbonize. But I didn’t foresee such a staggering near-term surge in electricity demand. (To be fair, even long-time students of the computing industry’s energy use didn’t see the coming increase, either.)
What I didn’t anticipate — or understand — were two fast-moving trends. The first was that the AI models were responding to scale: the more text or images they consumed, or training they received, or (crucially) computational power they had access to, the better they got. The second was that Wall Street was happy to pay to continue that speedy scale-up. As long as models kept getting better, investors were willing to keep lending or investing more money to the companies making them. Through the power of those two scaling functions, the data center boom became one of the biggest infrastructure buildouts in American history.
In recent days, the second of those trends has started to falter. After a surprisingly hot inflation report last week, and a disclosure on Wednesday evening that Meta has gone free cash flow negative to finance its ongoing AI buildout, stocks with any proximity to AI or data centers stumbled on Wall Street today. The data center developers Coreweave and Vistra were each down about 10%, while Microsoft, Alphabet, and Nvidia all fell in daily trading. Meta’s stock lost almost 7% of its value; GE Vernova, which produces gas turbines, was down 10%.
These declines look more significant when you zoom out. Since late June, a good chunk of the AI portfolio has sagged into the red. Coreweave’s stock is down 54% over the past six months. Alphabet and GE Vernova have also posted declines since the summer. (The trend isn’t uniform: Nvidia and Microsoft are still very much in the green.)
None of this, to be sure, guarantees that the AI boom is ending or even slowing down. But this finance-applied friction is what such a slowdown could look like. Investors aren’t (yet) saying that AI is a business dud, to be clear, just that companies perhaps don’t need to go and construct all this stuff so fast. And given what the data center buildout has meant for energy construction — not to mention greenhouse gas emissions — that’s a trend nobody in climate or energy can ignore.
The zero-emission pioneer is doing the dirty work for the AI boom.
All kinds of companies have refashioned themselves to exploit the AI boom. A bitcoin miner became a data center developer, a shoemaker is building GPUs, and an electric vehicle company is integrating its powertrains into server racks.
Now, a company that once aspired to build one of the lowest-emitting power plants has pivoted to building one of the dirtiest in order to meet data centers’ requirement for speed to power above all. Net Power was founded to pioneer a new form of natural gas power plant with zero emissions, but it has given up on that technology and recently acquired 10 natural gas reciprocating engines that it plans to co-locate with a data center on the site intended for its first commercial plant.
“We believe the clean piece is important,” Net Power CEO Danny Rice said during an August earnings call when he announced the company’s pivot to building unabated natural gas plants. “But just as it’s always been, it will only come at scale once society’s basic energy pillars of reliable, affordable power are fully in place. Power demand is outstripping supply today.”
Net Power’s pivot is a sign not only that the AI boom has eroded market appetite for clean power, but that U.S. policies supporting carbon capture — primarily the 45Q tax credit that President Trump’s One Big Beautiful Bill Act recently expanded — are still not enough to support the technology’s deployment in the power sector.
“The long history of doing CCS in the United States is there isn’t enough public funding to get companies to deploy it at scale,” Jack Andreasen Cavanaugh, a senior research associate at Columbia University’s Center on Global Energy Policy, told me.
This is actually the second major pivot the company has made in less than a year. Last November, Net Power was still testing its proprietary oxy-combustion technology at its demonstration site in La Porte, Texas. The tech was designed to burn natural gas in a chamber with pure oxygen, producing a purer stream of CO2 than when natural gas is burned in regular air. Net Power’s system could recycle some of that CO2 for power generation and capture the rest more efficiently than a conventional gas plant could. The company had not yet demonstrated that the system could generate more energy than it used, however.
By that point, Net Power had determined that its oxy-combustion plants, if they ever even did generate net power, would not be economically competitive anytime soon. In its 2025 Q3 financial report, the company said it had “decided to broaden the scope of its business” and develop more conventional natural gas plants with carbon capture equipment tacked on. It signed a letter of intent with Entropy, a Canadian company building “post-combustion” carbon capture equipment, to bring the tech to the United States, and ordered two 30-megawatt Siemens natural gas turbines for 2028 delivery.
“For us and everyone else in the power and data center space these days, speed is everything,” Rice said at the time. “We believe gas turbines with [post-combustion capture] can and should be the fastest-to-market and most cost-competitive clean, firm solution for our prospective customers.”
He told investors that rising costs were one of the setbacks Net Power faced in building its first-of-a-kind oxy-combustion plant. It was highly unlikely the company could finance and build a $1.7 billion, 200-megawatt plant before completing all its testing, he said. The best-case scenario for the plant to come online was 2030 or 2031, and costs might keep rising with inflation. The company could either bet on that prospect and keep bleeding cash, or “slow down that spending in order to free up some of our resources for near-term accretive opportunities.” As a public company with shareholders to answer to, there was really only one choice.
By the end of 2025, Net Power decided to suspend its oxy-combustion development and testing activities altogether, according to its year-end SEC filing.
Six months later, the company’s thesis changed again. Gas turbines with post-combustion capture, it turned out, were not the “fastest-to-market and most cost-competitive” solutions that the company had hoped they’d be. Whereas once upon a time, electricity buyers considered a range of factors when shopping around for power, including carbon emissions, the reality was that they were now only looking for three qualities: speed, reliability, and scale. “Natural gas power generation, co-located with customer load, and deployable on a fast timeline, is how we expect to meet that demand today,” Rice told investors, adding that the company hoped to add carbon capture to its projects in the future.
To date, only one proposed U.S. natural gas plant with carbon capture has announced a deal to sell its prospective power. In October 2025, Google signed a power purchase agreement with the Broadwing Energy Center, an Illinois plant under development by a company called Low Carbon Infrastructure.
“There is a massive demand for unabated gas right now, and there is much less of a demand for carbon capture,” Cavanaugh said. He told me there are still lots of conversations happening between hyperscalers and carbon capture companies, but the physical realities and costs of capturing, transporting, and storing carbon from natural gas plants remain obstacles.
The Global CCS Institute published its annual Global Status of CCS report this week, which found more than 266 carbon capture, transport, or storage projects are under development in the U.S., but permitting delays and policy uncertainty are stalling their progress. “Inflation and rising capital costs have weakened project economics, reducing the effectiveness of existing policies, such as tax and investment credits,” the report said.
That doesn’t mean there aren’t still companies trying. Net Power may have given up on oxy-combustion power plants for now, but Arbor Energy, a startup founded by former SpaceX engineers, is just ramping up. Arbor announced a milestone in the development of its own oxy-combustion power generator last week, running a key piece of its system — a supercritical CO2 turbocompressor — for more than two hours at high speeds.
Arbor differentiates itself by using 3D-printed turbines and developing smaller, more modular plants. It’s scaling more incrementally than Net Power tried to, starting with a 1-megawatt demonstration plant in California that is “weeks away” from operating, the company’s Chief Operating Officer Alicia Harmon told me — although the project won’t include carbon storage. It plans to build a 25-megawatt demonstration plant by 2028, also sans storage, before manufacturing commercial-scale systems.
Arbor actually went through a pivot of its own due to the data center boom. The founders originally planned to focus on bioenergy with carbon removal, using the oxy-combustion technology to generate power from biomass and storing the resulting CO2 underground. Over time, though, it became clear that demand for power outpaced demand for carbon removal, and natural gas was more abundant than biomass.
I asked Harmon whether the company thought there was market demand for carbon-capture gas plants. Is anyone willing to pay that green premium right now? “Honestly, my answer is no,” she said, but the company sees a path to erasing the green premium by the early 2030s. She added that Arbor’s technology is already “very close” to parity with combined-cycle natural gas plants when the 45Q tax credit is taken into account.
Last month, Net Power announced it had acquired 123 megawatts’ worth of Wärtsilä reciprocating engines, in addition to the Siemens turbines it had already ordered. Reciprocating engines are among the dirtiest natural gas power-generation technologies. A recent report from Earthjustice estimated that a 1-gigawatt plant powered by reciprocating engines would emit 1.5 times as much CO2 per year as one powered by the “combined cycle” technology most modern plants use, and twice as much nitrogen oxides and fine particulate matter. It has not yet disclosed any data center partners to sell the power to.
Net Power declined to comment on this story.
