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.)

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.

A new “foreign entities of concern” proposal might be just as unworkable as the House version.
In the House’s version of Trump’s One, Big, Beautiful Bill Act Republicans proposed denying tax credits to clean energy companies whose supply chains contained any ties — big or small — to China. The rules were so administratively and logistically difficult, industry leaders said, that they were effectively the same as killing the tax credits altogether.
Now the Senate is out with a different proposal that, at least on its face, seems to be more flexible and easier to comply with. But upon deeper inspection, it may prove just as unworkable.
“It has the veneer of giving more specificity and clarity,” Kristina Costa, a Biden White House official who worked on Inflation Reduction Act implementation, told me. “But a lot of the fundamental issues that were present in the House bill remain.”
The provisions in question are known as the “foreign entities of concern” or FEOC rules. They penalize companies for having financial or material relationships with businesses that are “owned by, controlled by, or subject to the jurisdiction or direction of” any of four countries — Russia, Iran, North Korea, and, most importantly for clean energy technology, China.
The Inflation Reduction Act imposed FEOC restrictions on just one clean energy tax credit — the $7,500 consumer credit for electric vehicles. Starting in 2024, if automakers wanted their cars to qualify, they could not use battery components that were manufactured or assembled by a FEOC. The rules ratcheted up over time, later disallowing critical minerals extracted or processed by a FEOC.
The idea, Costa told me, was to “target the most economically important components and materials for our energy security and economic security.” But now, the GOP is attempting to impose FEOC restrictions liberally to every tax credit and every component, in a world where China is the biggest lithium producer and dominates roughly 80% of the solar supply chain.
Not only would sourcing outside China be challenging, it would also be an administrative nightmare. The way the House’s reconciliation bill was written, a single bolt or screw sourced from a Chinese company, or even a business partially owned by Chinese citizens, could disqualify an entire project. “How in the world are you going to trace five layers down to a subcontractor who’s buying a bolt and a screw?” John Ketchum, the CEO of the energy company NextEra, said at a recent Politico summit. Ketchum deemed the rules “unworkable.”
The Senate proposal would similarly attach FEOC rules to every tax credit, but it has a slightly different approach. Rather than a straight ban on Chinese sourcing, the bill would phase-in supply chain restrictions, requiring project developers and manufacturers to use fewer and fewer Chinese-sourced inputs over time. For example, starting next year, in order for a solar farm to qualify for tax credits, 40% of the value of the materials used to develop the project could not be tied to a FEOC. By 2030, the threshold would rise to 60%. The bill includes a schedule of benchmarks for each tax credit.
“That might be strict, but it’s clearer and more specific, and it’s potentially doable,” Derrick Flakoll, the senior policy associate for North America at BloombergNEF, told me. “It’s not an all or nothing test.”
But how companies should calculate this percentage is not self-evident. The Senate bill instructs the Treasury department to issue guidance for how companies should weigh the various sub-components that make up a project. It references guidance issued by the Biden administration for the purposes of qualifying for a domestic content bonus credit, and says companies can use this for the FEOC rules until new guidance is issued.
Mike Hall, the CEO of a company called Anza that provides supply chain data and analytics to solar developers, told me he felt that the schedule was achievable for solar farm developers. But the Biden-era guidance only contains instructions for wind, solar, and batteries. It’s unclear what a company building a geothermal project or seeking to claim the manufacturing tax credit would need to do.
Costa was skeptical that the Senate bill was, in fact, clearer or more specific than the House version. “They’re not providing the level of precision in their definitions that it would take to be confident that the effect of what they’re doing here will not still require going upstream to every nut, bolt, screw, and wire in a project,” she said.
It’s also hard to tell whether certain parts of the text are intentional or a drafting error. There’s a section that Flakoll had interpreted as a grandfathering clause to allow companies to exempt certain components from the calculation if they had pre-existing procurement contracts for those materials. But Costa said that even though that seems to have been the intent, the way that it’s written does not actually achieve that goal.
In addition to rules on sourcing, the Senate bill would introduce strict ownership rules that could potentially disqualify projects that are already under construction or factories that are already producing eligible components. The text contains a long list defining various relationships with Chinese entities that would disqualify a company from tax credits. Perhaps the simplest one is if a Chinese entity owns just 25% of the company.
BloombergNEF analyzed the pipeline of solar and battery factories that are operational, under construction, or have been announced in the U.S. as of March, and quite a few have links to China. The research firm identified 22 firms “headquartered in China with Chinese parent companies or majority-Chinese shareholders” that are behind more than 100 existing or planned solar or battery factories in the U.S.
One example is AESC, a Japanese battery manufacturer that sold a controlling stake in the business to a Chinese company in 2018. AESC has two gigafactories under construction in Kentucky and South Carolina, both of which are currently paused, and a third operating in Tennessee. Another is Illuminate USA, a joint venture between U.S. renewables developer Invenergy and Chinese solar panel manufacturer LONGi; it began producing solar panels at a new factory in Ohio last year. The sources I reached out to would not comment on whether they thought that Ford, which has a licensing deal with Chinese battery maker CATL, would be affected. Ford did not respond to a request for comment.
Hall told me he would expect to see Chinese companies try to divest from these projects. But even then, if the business is still using Chinese intellectual property, it may not qualify. “It’s just a lot of hurdles for some of these factories that are already in flight to clear,” he said.
In general, the FEOC language in the Senate bill was “still not good,” he said, but “a big improvement from what was in the House language, which just seemed like an insurmountable challenge.”
Albert Gore, the executive director of the Zero Emissions Transportation Association, had a similar assessment. “Of course, the House bill isn’t the only benchmark,” he told me. “Current law is, in my view, the current benchmark, and this is going to have a pretty negative impact on our industry.”
A statement from the League of Conservation Voters’ Vice President of Federal Policy Matthew Davis was more grave, warning that the Trump administration could use the ambiguity in the bill to block projects and revoke credits. “The FEOC language remains a convoluted, barely workable maze that invites regulatory chaos, giving the Trump administration wide-open authority to worsen and weaponize the rules through agency guidance,” he wrote.
On storm damage, the Strait of Hormuz, and Volkswagen’s robotaxi
Current conditions: A dangerous heat dome is forming over central states today and will move progressively eastward over the next week • Wildfire warnings have been issued in London • Typhoon Wutip brought the worst flooding in a century to China’s southern province of Guangdong.
Hurricane Erick made landfall as a Category 3 storm on Mexico’s Pacific coast yesterday with maximum sustained winds around 125 mph. Damages are reported in Oaxaca and Guerrero. The storm is dissipating now, but it could drop up to 6 inches of rain in some parts of Mexico and trigger life-threatening flooding and mudslides, according to the National Hurricane Center. Erick is the earliest major hurricane to make landfall on Mexico's Pacific coast, and one of the fastest-intensifying storms on record: It strengthen from a tropical storm to a Category 4 storm in just 24 hours, a pattern of rapid intensification that is becoming more common as the Earth warms due to human-caused climate change. As meteorologist and hurricane expert Michael Lowry noted, Mexico’s Pacific coast was “previously unfamiliar with strong hurricanes” but has been battered by epic storms over the last two years. Acapulco is still recovering from Category 5 Hurricane Otis, which struck in late 2023.

An oil tanker collision near the Strait of Hormuz is raising environmental and security concerns. The accident in the Gulf of Oman involved the Adalynn and Front Eagle tankers. It caused a “small oil spill,” according to the Emirati government, but Greenpeace analyzed satellite images and said the oil plume stretches some six square miles from the collision site. “This is just one of many dangerous incidents to take place in the past years,” said Greenpeace campaigner Farah Al Hattab. The Strait of Hormuz is a choke point for oil shipments, with about one-third of the volume of crude exported by sea moving through that route. Oil prices have been on a roller coaster ride since Israel launched airstrikes against Iran on June 13. Ships in the region have been reporting more GPS navigation interference in recent days. “If the conflict continues, we expect these interferences to continue as well,” Jean-Charles Gordon, senior director of ship tracking at research firm Kpler, toldThe New York Times.
North Carolina lawmakers finalized a bill repealing a mandate that directs electric regulators to reduce their carbon dioxide emissions by 70% by 2030. The mandate was part of a landmark 2021 law aimed at dramatically reducing the state’s power plant emissions. While at least 17 other states have similar laws in place, just two – North Carolina and Virginia – are in the Southeast. The new bill’s supporters say that the interim emissions goal would require energy providers to switch to more expensive power sources and that the costs would be passed on to consumers in the form of higher power bills.
Confusingly, regulators would still be asked to work toward carbon neutrality by 2050, even while the short-term emissions goal might be nixed. “Not having any target, even an aspirational target, could mean that we don’t stay on track to get to our 2050 goal,” Democratic Sen. Julie Mayfield said. The bill now goes to Democratic Gov. Josh Stein’s desk. There’s a chance he might veto it, but “with over a dozen House and Senate Democrats voting for the final version, the chances that any Stein veto could be overridden are higher,” The Associated Pressreported.
The United Kingdom issued long-awaited environmental guidance that it will use to determine whether new oil and gas proposals should be approved. The guidance requires that developers estimate and include scope 3 emissions – or the downstream pollution from burning oil and gas – in their drilling applications. This “will ensure the full effects of fossil fuel extraction on the environment are recognized in consenting decisions,” the Department for Energy Security and Net Zero said. The government will consider these emissions, as well as other factors like “the potential economic impact” of a project and a company’s efforts to remove carbon dioxide when granting or denying approval. The guidance will help determine whether major new drilling projects from oil giants Shell and Equinor are approved for the North Sea.
Volkswagen Group unveiled its first fully autonomous production vehicle, the ID. Buzz AD. The electric robotaxis will target corporate customers and mobility services. They “come packed with everything that’s needed to operate them,” explained Iulian Dnistran at InsideEVs. “What makes this solution interesting compared to other ride-hailing platforms is that it enables anybody to start an Uber or Waymo rival without investing hundreds of millions of dollars in research, development, and certification.” The shuttles are slated for launch across Europe and the U.S. next year. Tesla recently announced that its first Robotaxis would hit the streets in Austin, Texas, sometime this month.

In a new peer-reviewed paper published in the journal Communications Earth & Environment, researchers conclude that offsetting the potential carbon emissions from reserves held by the world’s 200 largest fossil fuel companies would require planting new forests that are larger than the entire continent of North America.
The energy secretary's philosophy is all over the Senate mega-bill.
As the Senate Finance Committee worked on its version of the reconciliation bill that would, among things, overhaul the Inflation Reduction Act, there was much speculation among observers that there could be a carve out for sources of power like geothermal, hydropower, and nuclear, which provide steady generation and tend to be more popular among Republicans, along the lines of the slightly better treatment received by advanced nuclear in the House bill.
Instead, the Senate Finance Committee’s text didn’t carve out these “firm” sources of power, it carved out solar and wind, preserving tax credits for everything else through 2035, while sunsetting solar and wind by 2028.
For much of the last few months — and for years before he was sworn in as Secretary of Energy — Chris Wright has been expounding on his philosophy of energy and climate. If anything, the Senate Finance draft seems to hew closer to Wright’s worldview than Trump’s, which is less specific, even more critical of renewables (especially wind), and largely in favor of nuclear power when it comes to non-carbon-emitting generation.
“I’m sure Secretary Wright’s strong support for firm technologies over the past few months played a role in Chairman Crapo’s approach to energy tax credit reform,” Pavan Venkatakrishnan, an infrastructure fellow at the Institute for Progress, told me.
Wright argues that climate change is real but not a top-tier concern and that it certainly should not be addressed by restricting energy usage, which he sees as foundational to the good life here and abroad.
And among energy sources, the former fracking executive is no opponent of fossil fuels but is also enthusiastic about energy innovation.
In his company Liberty Energy’s Bettering Human Lives report, published last year, which doubles as a kind of manifesto, Wright wrote that “viable paths to reducing greenhouse gas (GHG) emissions can only come from reliable and affordable low-carbon energy technologies,” and specifically listed next-generation nuclear and geothermal, which Liberty had invested in through the geothermal company Fervo and nuclear company Oklo.
“To achieve largescale human betterment, we will need significant future energy additions from nuclear, hydropower, geothermal, and all other viable energy technologies,” the report read.
And he’s often been skeptical of renewables along the lines of many Congressional Republicans, that they aren’t reliable enough and require additional resources to fully support the grid.
“Maybe the biggest problem is intermittency,” Wright said at a Liberty Energy event last year.
“You can build a lot of wind and solar, and then at night, the sun’s not shining and then sometimes the wind doesn’t blow, and you have no energy. So to keep society running, you have to have a whole second separate energy system,” Wright said.
In testimony to the House of Representatives last week, Wright said “If you’re not there at peak demand, you’re just a parasite on the grid, because you just make the other sources turn up and down as you come and go.”
Many critics of the Republican reconciliation bills have noted that much of the electricity generation pipeline is solar, wind, or storage, and so cutting off their tax credits risks leaving the country at an energy shortage while gas turbines take years and years to actually get on the grid.
But as Congress was working on the reconciliation bill, Wright made a series of widely noted public appearances where he promoted clean firm power and continued government support for it.
“My recommendation has been to leave behind the equivalent of the wind and solar tax credits — through if you start construction by 2031 — for nuclear fission and fusion and geothermal,” Wright said at an event earlier this month.
In May, Wright addressed the Nuclear Energy Institute, outlining his support for sunsetting wind and solar tax credits will working to kickstart nuclear power. “My personal goal would be to much more rapidly sunset the technologies that have been around and have been living on decades of subsidies,” Wright said. He also supported a “window” of “favorable treatment” for nuclear and geothermal.
“I’m in favor of every nudge, every incentive we can get from the federal government to restart this industry,” Wright said.
While Wright has been skeptical of wind and solar and optimistic about nuclear and geothermal for years, he’s also started talking more positively about energy storage. In the past, he’s talked up hydrocarbons for “coming with their own storage,” as he put it in a 2018 podcast.
But at an appearance at ARPA-E in March, Wright gave some of his most extended thoughts on energy storage, which sits somewhat awkwardly between variable resources like solar and wind and firm resources like nuclear and geothermal.
“Solar is growing very fast, getting more efficient and taking panels, cheaper materials and developing energy,” Wright said. “The biggest problem there is the sun doesn’t always shine, and we don’t know when clouds are going to come and when it’s not going to shine, but if we can get energy storage better, that’s a game changer.”
At least until 2035.
