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.

Renewable energy just became a much more enticing investment.
That’s thanks to the Federal Reserve, which announced today that it would reduce the benchmark federal funds rate by half a percentage point, from just over 5% to just below. It’s the beginning of an unwinding of years of high interest rates that have weighed on the global economy and especially renewable energy.
The Federal Reserve’s economic projections also indicated that the federal funds rate could fall another half point by the end of the year and a full point in 2025. The Federal Reserve began hiking interest rates from their near-zero levels in March 2022 in response to high inflation.
High interest rates, which drive up the cost of borrowing money, have an outsize effect on renewable energy projects. That’s because the cost of building and operating a renewable energy generator like a wind farm is highly concentrated in its construction, as opposed to operations, thanks to the fact that it doesn’t have to pay for fuel in the same way that a natural gas or coal-fired power plant does. This leaves developers highly exposed to the cost of borrowing money, which is directly tied to interest rates. “Our fuel is free, we say, but our fuel is really the cost of capital because we put so much capital out upfront,” Orsted Americas chief executive David Hardy said in June.
So what does that mean in practice? Let’s look at some numbers.
Wood Mackenzie estimates that a 2% increase in interest rates pushes up the cost of energy produced by a renewables project by around 20%, compared to just over 10% for conventional power plants.
Meanwhile the investment bank Lazard estimates that reducing the cost of capital (the combined cost of borrowing money and selling equity in a project, both of which can be affected by interest rates) from 7.7% — the bank’s rough assumption over the summer — to 5.4% would lower the levelized cost of energy for an offshore wind system from $118 to $97 — around 17% — and for a utility solar project from $76 to $54 — roughly 28%. While there's not a one-to-one relationship between interest rates and the cost of capital, they move in the same direction.
Reductions in cost of capital also make more renewables project viable to finance. According to a model developed by the Center for Public Enterprise, a typical renewable energy project with a weighted average cost of capital of 7.75% will have a debt service coverage ratio (a project’s cash flow compared to its loan payments)of 1.16. Investors consider projects to be roughly viable at 1.25.
So at the cost of capital assumed by Lazard, many projects will not get funded because investors don't see them as viable. If the weighted average cost of capital were to fall one percentage point to 6.75%, a project’s debt service coverage ratio would rise to 1.28, just above the viability threshold. If it fell by another percentage point, the debt ratio would hit a likely compelling 1.43.
“As rates fall, projects become increasingly financially viable,” Advait Arun, senior associate of energy finance at the Center for Public Enterprise and Heatmap contributor, told me matter-of-factly.
Why farmers are becoming the new nemeses of the solar and wind industries
Farms are fast becoming one of the most powerful opponents to renewable energy in the United States, second perhaps only to the fossil fuel industry. And it’s frighteningly unclear how developers will resolve this problem – or if they even can.
As solar and wind has grown rapidly across the country, so too have protests against solar and wind power on “prime farmland,” a loose term used by industry and government officials to describe property best suited for growing lots of crops. Towns and counties are banning the construction of solar and wind farms on prime farmland. State regulators – including those run by Democrats – are restricting renewable development on prime farmland, and members of Congress are looking at cutting off or restricting federal funds to projects on prime farmland.
In theory, meeting our country’s climate goals and industry needs should require very little farmland. But those same wide expanses flush with sunlight and gusts of wind sought after by developers happen to often be used by farmers: A USDA study released this year found more than 90% of wind turbines and 70% of solar farms in rural areas were sited on agricultural land.
It would be easy for an activist or energy nerd to presume this farmland free-for-all is being driven by outside actors or adverse incentives (and there’s a little bit of that going on, as we’ll get to).
However, weeks of reporting – and internal Heatmap News datasets – have revealed to me that farmland opposition actually has a devilishly simple explanation: many large farm owners are just plain hostile to land use changes that could potentially, or even just hypothetically, impact their capacity to grow more crops.
This means there is no easy solution and as I’ll explain, it is unclear whether the renewables sector’s efforts to appear more accommodating to agricultural businesses – most notably agri-voltaics – will stem the tide of local complaints from rural farmers.
“This is a new land use that is very quickly accelerating across the country and one of the major reactions is just to that fact,” Ethan Winter of American Farmland Trust, a nonprofit promoting solar education in farm communities, told me. “These are people who’ve been farming this land for generations in some instances. The idea of doing anything to take it out of agricultural production is just hard for them, for their community, and it’s about the culture of their community, and if solar is something that can be considered compatible with agriculture.”
Over 40% of all restrictive ordinances and moratoriums in Heatmap Pro's database are occurring in counties with large agricultural workforces.
In fact, our internal data via Heatmap Pro has found that agricultural employment can be a useful predictor of whether a community will oppose the deployment of renewables. It's particularly salient where there's large-scale, capital-intensive farming, likely because the kind of agriculture requiring expensive machinery, costly chemicals, and physical and financial infrastructure — think insurance and loans — indicates that farming is the economic cornerstone of that entire community.
Resentment against renewables is pronounced in the Corn Belt, but it’s also happening even in the bluest of states like Connecticut, where state environmental regulators have recommended against developing on prime farmland and require additional permits to build on preferred fertile soils. Or New York, where under pressure from farming groups including the state Farm Bureau, the state legislature last year included language in a new permitting authority law limiting the New York Power Authority from approving solar and wind on “land used in agricultural production” unless the project was agrivoltaics, which means it allows simultaneous farming of the property. The state legislature is now looking at additional curbs on siting projects in farmland as it considers new permitting legislation.
Deanna Fox, head of the New York Farm Bureau, explained to me that her organization’s bottom-up structure essentially means its positions are a consensus of its grassroots farm worker membership. And those members really don’t trust renewables to be safe for farmland.
“What happens when those solar arrays no longer work, or they become antiquated? Or farmland loses its agricultural designation and becomes zoned commercial? How does that impact ag districting in general? Does that land just become commercial? Can it go back to being agricultural land?” Fox asked. “If you were to talk to a group of farmers about solar, I would guarantee none of them would say anything about the emotional aspect of it. I don’t think that's what it really is for them. [And] if it’s emotional, it’s wrapped around the economics of it.”
Surveys of farmers have hinted that fears could be assuaged if developers took steps to make their projects more harmonious with agricultural work. As we reported last week, a survey by the independent research arm of the Solar Energy Industries Association found up to 70% of farmers they spoke with said they were “open to large-scale solar” but many sought stipulations for dual usage of the land for farming – a practice known as agrivoltaics.
Clearly, agrivoltaics and other simultaneous use strategies are what the industry wants to promote. As we hit send on last week’s newsletter, I was strolling around RE+, renewable energy’s largest U.S. industry conference. Everywhere I turned, I found publicity around solar and farming.
The Department of Energy even got in on the action. At the same time as the conference, the department chose to announce a new wave of financial prizes for companies piloting simultaneous solar energy and farming techniques.
“In areas where there has been a lot of loss of farmland to development, solar is one more factor that I think has worried folks in some communities,” Becca Jones-Albertus, director of DOE’s solar energy technologies office, told me during an interview at the conference. However agri-voltaics offer “a really exciting strategy because it doesn’t make this an either or. It’s a yes and.”
It remains to be seen whether these attempts at harmony will resolve any of the discord.
One industry practice being marketed to farm communities that folks hope will soften opposition is sheep grazing at solar farms. At RE+, The American Solar Grazing Association, an advocacy group, debuted a documentary about the practice at the conference and had an outdoor site outside the showroom with sheep chilling underneath solar panel frames. The sheep display had a sign thanking sponsors including AES, Arevon, BP, EDF Renewables, and Pivot Energy.
Some developers like Avangrid have found grazing to be a useful way to mitigate physical project risks at solar farms in the Pacific Northwest. Out in rural Oregon and Washington, unkempt grasslands can present a serious fire risk. So after trying other methods, Avangrid partnered with an Oregon rancher, Cameron Krebs, who told me he understands why some farmers are skeptical about developers coming into their neck of the woods.
“Culturally speaking, this is agricultural land. These are communities that grow wheat and raise cattle. So my peers, when they put in the solar farms and they see it going out of production, that really bothers the community in general,” he said.
But Krebs doesn’t see solar farms with grazing the same way.
“It’s a retooling. It may not be corn production anymore. But we’re still going to need a lot of resources. We’re still going to need tire shops. I think there is a big fear that the solar companies will take the land out of production and then the meat shops and the food production would suffer because we don’t have that available on the landscape, but I think we can have utility scale solar that is healthy for our communities. And that really in my mind means honoring that soil with good vegetation.”
It’s important to note, however, that grazing can’t really solve renewables’ farmland problem. Often grazing is most helpful in dry Western desert. Not to mention sheep aren’t representative of all livestock – they’re a small percentage. And Heatmap Pro’s database has found an important distinction between farms focused on crops versus livestock — the latter isn’t as predisposed to oppose renewable energy.
Ground zero for the future of renewables on farmland is Savion's proposed Oak Run project in Ohio, which at up to 800 megawatts of generation capacity would be the state’s largest solar farm. The developer also plans to let farmers plant and harvest crops in between the solar arrays, making it the nation’s largest agri-voltaics site if completed.
But Oak Run is still being opposed by nearby landowners and local officials citing impacts to farmland. At Oak Run’s proposed site, neighboring township governments have passed resolutions opposing construction, as has the county board of commissioners, and town and county officials sued to undo Oak Run’s approval at the Ohio Power Siting Board. Although that lawsuit was unsuccessful, its backers want to take the matter to the state Supreme Court.
Some of this might be tied to the pure fact Ohio is super hostile to renewables right now. Over a third of counties in the state have restricted or outright banned solar and wind projects, according to Heatmap Pro’s database.
But there’s more at play here. The attorney representing town and county officials is Jack Van Kley, a lawyer and former state government official who remains based in Ohio and who has represented many farms in court for myriad reasons. I talked to Van Kley last week for an hour about why he opposes renewables projects (“they’re anything but clean in my opinion”), his views on global warming (“I don’t get involved in the dispute over climate change”) and a crucial fact that might sting: He says at least roughly two thirds of his clientele are farmers or communities reliant on agricultural businesses.
“It’s neighbor against neighbor in these communities,” he told me. “You’ve got a relatively low number of farmers who want to lease their land so that the solar companies can put solar panels on them for thirty or forty years, and it’s just a few landowners that are profiting from these projects.”
Van Kley spoke to a concern voiced by his clients I haven’t really heard addressed by solar developers much: overall impacts to irrigation. Specifically, he said an outsized concern among farmers is simply how putting a solar or wind farm adjacent or close to their property will impact how groundwater and surface water moves in the area, which can impact somebody’s existing agricultural drainage infrastructure.
“If you do that next to another property that is being farmed, you’ll kill the crop because you’ll flood the crop,” he claimed. “This is turning out to be a big issue for farmers who are opposing these facilities.”
Some have tried to paint Van Kley as funded or assisted by the fossil fuel lobby or shadowy actors. Van Kley has denied any involvement in those kinds of backroom dealings. While there’s glimpses of evidence gas and coal money plays at least a minor role with other characters fomenting opposition in the state, I really have no evidence of him being one of these people right now. It’s much easier and simpler to reason that he’s being paid by another influential sect – large landowners, many of whom work in agriculture.
That’s the same conclusion John Boeckl reached. Boeckl, an Army engineer, is one of the property owners leasing land for construction of the Oak Run project. He supports Oak Run being built and has submitted testimony in the legal challenge over its approvals. Though Boeckl certainly wants to know more about who is funding the opposition and has his gripes with neighbors who keep putting signs on his property that say “no solar on prime farmland,” he hasn’t witnessed any corporate skullduggery from shadowy outside entities.
“I think it’s just farmers being farmers,” he said. “They don’t want to be told what to do with their land.”
A look at the conflicts around renewable energy projects over the past week
1. Newport County, Rhode Island – I’ve learned that climate activists in Rhode Island are now using local protests to oppose NIMBYs who are challenging renewables projects.
2. Coos County, Oregon – The Confederated Tribes of the Coos, Lower Umpqua, and Siuslaw Indians have sued the Bureau of Ocean Energy Management requesting it delay an offshore wind lease sale scheduled on Oct. 15.
3. Polk County, Iowa – Landowners have sued the Iowa Utilities Commission over permitting the Summit Carbon Solutions CO2 pipeline and providing eminent domain authority, the latest in a string of setbacks that has galvanized local opposition from the midwest to the Dakotas.
4. Houston County, Georgia – One of Georgia’s largest proposed solar projects has been rejected by a potential host county over its potential impacts to bear habitat and property values.
Here’s what else I’m watching…
