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.

In Providence, at least, climate change is still on the ballot.
Here’s some trivia for you: What was the first state to see its average temperature break the 2-degree Celsius threshold for warming above pre-industrial levels? It wasn’t Alaska, the fastest-warming state, nor was it California or Florida, states with some of the most visible impacts of the extreme weather crisis. It was not Arizona or Texas, either, though “hot” and “warming” are often conflated.
The answer, in fact, is humble Rhode Island, which passed the international benchmark for accelerated climatic impacts back in 2019. It is perhaps less surprising, then, to learn that in the Ocean State’s largest city, Providence, climate change and how to adapt to it have become one of the central talking points in a heated mayoral race, which in the deep-blue city is likely to culminate in the September 9 primary.
There is plenty to worry voters. Providence sits at the head of Narragansett Bay, which has warmed 1.6 degrees Celsius, enough to drive lobsters from the region and convert the local lobstermen into crabbers, fishing for crustaceans they previously considered bycatch. The sea level has risen on Rhode Island’s 400-plus miles of coastline by more than 10 inches since 1930, more than in Venice or Miami, meaning the city floods frequently. Locals hold their breath every hurricane season; a hit from a category 4 or larger storm could tally billions in damages. And as home to the biggest port in the region, Providence is also an unfortunate case study in industrial and fossil-fuel-related pollution affecting historically redlined neighborhoods.
“Since I’ve been in office, we’ve had dramatic, chronic flooding. We’ve had high heat days in the fall that have closed public schools, which is not something that ever happens here in September,” Providence Mayor Brett Smiley told me. “We had some of the highest snowfall in recorded history [in the city]. We’re seeing the effects.”
Smiley, who was elected in 2022, has described investing in infrastructure upgrades for the nearly four-century-old city as one of his “principal responsibilities” as mayor. During his second year in office, he signed an ordinance requiring all of the 122 city-owned buildings to decarbonize by 2040, and that fall published a 10-year plan that introduced air quality, heat, and stormwater management goals, provisions aimed at curbing pollution at the Port of Providence, and would have effectively banned the construction of new gas stations. (A later amendment relaxed the restrictions.) He’s also invested in long-overdue repairs to the city’s hurricane barriers.
This year, Smiley also announced the creation of a Green Revolving Fund to support Providence’s ambitious carbon neutrality goals. “I’ve been in government long enough to know that operating budgets can change as priorities change, and so having a dedicated recurring revenue stream is vital to ensuring that this work continues,” he said.
In the face of federal headwinds, and at a time when the political currency of “climate change,” at least in so many words, is on the downswing, Smiley’s focus on climate issues stands out. That is especially true against the backdrop of a broader state-level reassessment of environmental goals, with Democratic Governor Dan McKee proposing a budget earlier this year that would have slashed climate programs funded by monthly utility charges in the name of affordability. Though Rhode Island lawmakers ultimately rejected that rollback, McKee’s move fits into a larger trend in the region of blue-state politicians in places like Maryland, Massachusetts, and New York curbing or weakening climate ambitions under the pressure of affordability politics. (McKee also faces his own competitive primary.)
“Providence alone can’t solve the climate crisis. But our actions, at least in Rhode Island, are pushing other communities in the state to take action,” Smiley said.
But there are others — including Smiley’s progressive challenger, State Representative David Morales — who say the mayor’s tenure has been a lot of talk and little action, and that he’s neglected Providence’s low-income and frontline communities.
Morales’ campaign did not get back to me for this article, despite requests through multiple channels. But Steve Ahlquist, an independent reporter who follows environmental justice-related issues in Rhode Island, also told me that “over the years, and also in dealing with Mayor Smiley as an incumbent, I’ve had some real difficulty with what I would even call basic honesty out of his administration.” He added that the mayor’s office has a history of downplaying and denying police harassment of unhoused people in particular, including lying about the presence of police officers at a homeless encampment and their involvement in an “illegal search” in 2023.
When I asked the Smiley administration about Ahlquist’s accusations, press secretary Carl Austin Miller Grondin told me the city has a “multi-department approach” for addressing encampments of which “Providence Police are one piece,” though he didn’t address the 2023 incident directly. As for the idea that Smiley represents the status quo, Grondin said the mayor has made “significant investments” in programs for underprivileged groups including affordable housing, eviction prevention, public schools and youth programming, and public safety.
Ahlquist also finds Smiley’s talk about affordability and clean energy false, however. Smiley notably vetoed a rent control ordinance, despite the city having some of the highest rates in the country, and while serving as former Governor Gina Raimondo’s chief of staff between 2016 and 2019, he helped push for the expansion of fossil fuel infrastructure in the form of a $1 billion fracked gas and diesel oil power plant that was ultimately thwarted by community pushback. (Grondin told me “rent control policies do not lower rents” and that the mayor “has instead taken a disciplined, results-driven approach to lowering housing costs.” The power plant project was proposed before Smiley’s tenure in Raimondo’s administration, he added.)
Morales, 27, is a Democratic Socialist and has won the backing of Vermont’s Independent Senator Bernie Sanders. His scrappy campaign against an establishment incumbent Democrat has earned him comparisons to New York City’s young, charismatic Mayor Zohran Mamdani. Unlike Mamdani, however, Morales has made climate central to his campaign.
Morales has gone after Smiley particularly hard on environmental justice issues, sensing a weak spot in his record. “Industrial facilities near the Port of Providence have polluted our neighborhoods for decades,” his issues page reads. “David will require them to contribute more toward the city services and infrastructure our communities deserve.”
A nearly two-mile stretch of Allens Avenue, which flanks the port, is home to asphalt plants, scrap metal recyclers, oil and gas companies, and petroleum storage tanks with a history of leaks, spills, dumps, and other forms of contamination. Locals complain that even just driving along the avenue is enough to make you sick, with 11 identified polluters within a mile radius of National Grid’s newest LNG plant. Traffic to and from the port adds to the odor — and health impacts — in the neighboring communities of South Providence and Washington Park, which have some of the highest hospitalization rates in southern New England. Notably, South Providence’s population is 90% people of color; Washington Park’s is above 60%.
Smiley bristled at Morales’ plan to tax polluters. “Many of my opponent’s proposals — which continue to evolve, by the way — are illegal or not allowed, and he leaves some of those details out, and sometimes changes his position,” he told me. Ahlquist, who issued a rare endorsement of Morales last spring, contends that “we know for a fact it is not illegal” to tax polluters at a different rate. (In truth, it’s a bit of a legal gray area; Providence’s tax code allows it to adopt a classification system with different rates for industrial properties, but whether that classification can be used to single out specific polluters on Allens Avenue is murkier.)
In an interview with Ahlquist, Morales has also proposed buying out the Rhode Island Recycled Metals property — where some of the worst contamination has originated — and pursuing “brownfield mediation” in the area. “I find it shameful that Public Street, one of the few shoreline access points around the Port of Providence, is not a very welcoming environment,” he said. On the adaptation side, he’s proposed passing a green energy bond to invest in renewable energy and upgrade the sewage system with an eye on future flooding.
A week ago, it might have seemed as though Morales had progressive momentum on his side. But after the upset of Democratic Socialist Francesca Hong in Wisconsin on Tuesday night and the narrow victory by progressive up-and-comer Abdul El-Sayed in Michigan the week before, the narrative is now more complicated. Meanwhile, the first primary poll shows Smiley with a 4-point edge — within the margin of error, but still likely to have the Morales campaign in a state of jitters.
Climate adaptation can sometimes fall under a variation of the refrain parodied in urban infrastructure circles: One more study would fix this. That’s especially true in Rhode Island, where study after study has highlighted the problems Morales and Smiley are circling, and yet here they still are, at the center of yet another mayoral race.
“One of the things that frustrates me is when you write a plan and then put it on the bookshelf, and that’s the end of it,” Smiley told me, sounding genuinely irked as we spoke on the phone. “That’s not how I do plans.” He told me stormwater infrastructure would be a major focus of his administration if he’s elected to another term, while he hopes his decarbonization roadmap and the green revolving fund will outlast his mayoralty, whenever and however it may end.
Morales has been stymied before, too. Ahlquist recalled watching the young legislator in the State House at the end of a legislative session, when, in the waning hours, he was told by leadership that a bill he’d been working on wasn’t going to get through. “David, when he’s in public, he’s very controlled, very managed,” Ahlquist said. But from his vantage point, Ahlquist could see Morales had started to cry.
“It’s midnight, the last days of session, and I just saw something raw in him then,” Ahlquist said. “It was like, Wow, this is a guy who really gives a shit.”
Editor’s note: This story has been updated to include responses from the Smiley campaign.
Chatting about win-win solutions with the Abundance Institute’s Ryan Norris.
This week’s conversation is with Ryan Norris, senior fellow for energy policy at the Abundance Institute. The libertarian-leaning institute — whose name cleverly shortens to AI — is a new-ish entity with increasing relevance in energy and tech spaces. As Norris and I discussed, it’s starting to help shape policy on data center development and the generation that’ll power it all, especially in Republican circles. Norris himself previously worked with Americans for Prosperity, a right-wing political organization. I reached out to him and asked if we could chat because I wanted to know more about the institute’s work within the energy space. He wound up saying a lot more than I expected. So let’s dive into it.
The following conversation was lightly edited and abridged for clarity.
So let’s start with what you’re working on. What’s on your desk these days?
Here at Abundance, we sit at the juncture of emerging technology and the energy they need to bring that new technology to bear to impact life positively. We are always in a constant state of learning and researching what the latest thoughts and feelings are around certain policies, particularly around AI and data centers, and then energy technology. How do they feel about nuclear? Geothermal? Solar and battery arrays?
A lot of what I’m working on is Project Gigawatt, a body of policy that fits into permitting, generation, the grid, transmission, and then market and demand. Policies that we believe will generate more, transmit more, and as much of a free market approach as possible. Knowing that a lot of states have regulated utilities, when the state utility can’t produce what the state can potentially actually generate or would need to in order to accommodate large loads, we think there needs to be other opportunities to either bring that power or purchase it in a different way.
When it comes to this policy set, how are you taking into account the intensifying backlash to data center and AI infrastructure, as well as the energy attached to it?
As everyone can sense, things are moving rapidly, and there is a natural inclination to question how fast we’re going. I think these concerns need to be addressed seriously and respectfully. You can’t just say negative things about people who care about water quality or impacts to their local economies. Those are valid. I’ve lived through those. I come from a rural place in Arkansas that had oil and gas plays. And I’ve seen there needs to be conversations with people living in those areas too.
We cannot discount the backlash. When you take the legitimate concerns and pair them with the opportunities coming, I think there’s actually a chance to set up win-win solutions. It shouldn’t be a win-lose scenario here. They have skepticism about AI in the short and long term — that’s a natural inclination and not a negative, per se. But educating people and policymakers about data centers, that’s important.
What is your approach to the rise in land use regulation around data centers and energy infrastructure, moratoria and restrictive ordinances?
As much as possible, you want the infrastructure and cost allocation to be borne by the business causing it. That’s the motivation behind a lot of colocation partnerships happening right now, like the Kilby project in Texas, with natural gas powering a Microsoft hyperscale.
To us, it’s about setting up the opportunity for private property owners to sell to those hyperscalers and those generating the energy. Setting up situations where you’re not stopping people from benefiting. A lot of the “bring your own power” concept, we really like that. Maybe having it where power purchase agreements are more in the mix, things along those lines. That’s where I see things.
The energy increases to our utility bills, people are concerned about it, and that’s a bread and butter issue. That’s the approach: We know we need grid upgrades and want to have the most cost effective versions of those as possible, but you want those needing the power paying for it and not putting it on the backs of residents.
I’m curious, what’s you and your organization’s approach to the rise of gas infrastructure built for AI and the potential impacts that could have on climate change?
I don’t discount the issue of climate change.
Let’s say we’re not able to decarbonize enough to reverse the effects of warmth. We know we’ll have to create energy. We know we have other options for energy that need to be in the mix — more nuclear, which now even some of those who are climate-minded understand is an abundant energy source. I’m also interested in new technologies in geothermal where it can be viable in more places than we thought. You can drill down and tap hot rocks, a basin of water, turn a turbine, and that’s more acceptable for those who care about the climate. And states are looking at it, including my state of Arkansas. I bring these up because I also care about sources that provide firm, consistently available power.
We attended the American Legislative Exchange Council, and one of the things we do, we’re voting members on the energy, environment, and agriculture task force. We’re pro letting the market decide what they need. So we took opposite stances from what people typically consider normal standards on the center-right about banning “net-zero” for local governments. It did pass as model legislation but if we believe “all of the above” is the approach, we also want to be principally correct to ourselves that it doesn’t mean banning wind or solar where it’s viable.
My last question: What’s your thought on the future of politics around AI infrastructure and energy generation for it?
There’s definitely headwinds to those in that industry. I think the sense is, they understood what they wanted and didn’t see any barriers to the way they’d go about it. That’s causing ripple effects in our politics at the local level, including here in Arkansas, where I live in Pulaski County. I think it’ll stay important particularly as it connects to affordability concerns around energy. We know we need more energy, but we want it at the lowest cost possible to the residential side. If people are feeling like data centers are driving the demand for the energy and aren’t on the hook for it, that’s going to position them to be more negative towards the technology.
But we have to expand the conversation. There are folks out there talking about 3D printing for homes, using proprietary cement mixes to build homes in a few weeks when they took months. Agriculture is using robotics in lieu of pesticides and herbicides. Advanced manufacturing is improving the quality of medical equipment. No one completely understands the end goal of new energy to fuel the data centers and AI to get us where there’s a net benefit to them.
Plus more of the week’s biggest development fights.
1. Shelby County, Alabama — The Trump administration’s widening effort to intervene in rural energy project fights is facing an early test: What happens if companies don’t take it seriously?
2. Ozaukee County, Wisconsin — Speaking of walls, we just saw the political power of the data center resistance hit one in the Badger State.
3. Everywhere in Texas — Texas Governor Greg Abbott is getting a lot of love for his data center standards, with major developers rolling out press statements claiming they’ll comply.
4. Herkimer County, New York — Something weird is going on in upstate New York with a monastery, a wind farm, and the Trump administration. I’m not sure what to make of it yet.
