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.

Flames have erupted in the “Blue Zone” at the United Nations Climate Conference in Brazil.
A literal fire has erupted in the middle of the United Nations conference devoted to stopping the planet from burning.
The timing couldn’t be worse. Today is the second to last day of the annual climate meeting known as COP30, taking place on the edge of the Amazon rainforest in Belém, Brazil. Delegates are in the midst of heated negotiations over a final decision text on the points of agreement this session.
A number of big questions remain up in the air, including how countries will address the fact that their national plans to cut emissions will fail to keep warming “well under 2 degrees Celsius,” the target they supported in the 2015 Paris Agreement. They are striving to reach agreement on a list of “indicators,” or metrics by which to measure progress on adaptation. Brazil has led a push for the conference to mandate the creation of a global roadmap off of fossil fuels. Some 80 countries support the idea, but it’s still highly uncertain whether or how it will make its way into the final text.
Just after 2:00 p.m. Belém time, 12 p.m. Eastern, I was in the middle of arranging an interview with a source at the conference when I got the following message:
“We've been evacuated due to a fire- not exactly sure how the day is going to continue.”
The fire is in the conference’s “Blue Zone,” an area restricted to delegates, world leaders, accredited media, and officially designated “observers” of the negotiations. This is where all of the official negotiations, side events, and meetings take place, as opposed to the “Green Zone,” which is open to the public, and houses pavilions and events for non-governmental organizations, business groups, and civil society groups.
It is not yet clear what the cause of the fire was or how it will affect the home sprint of the conference.
Outside of the venue, a light rain was falling.

The Trump administration on Wednesday proposed significant new limits on federal protection under the Endangered Species Act. A series of four tweaked rules would reset how the bedrock environmental law to prevent animal and plant extinctions could be used to block oil drilling, logging, and mining in habitats for endangered wildlife, The New York Times reported. Among the most contentious is a proposal to allow the government to consider economic factors before determining whether to list a species as endangered. Another change would raise the bar for enacting protections based on predicted future threats such as climate change. “This administration is restoring the Endangered Species Act to its original intent, protecting species through clear, consistent and lawful standards that also respect the livelihoods of Americans who depend on our land and resources,” Secretary of the Interior Doug Burgum said in a statement.
In Congress, meanwhile, bipartisan reforms to make federal permitting easier are advancing. Representative Scott Peters, the Democrat in charge of the permitting negotiations, called the SPEED Act introduced by Representative Bruce Westerman, the Republican chairman of the Natural Resources Committee, a “huge step forward,” according to a post on X from Politico reporter Josh Siegel. But Peters hinted that getting the legislation to the finish line would require the executive branch to provide “permit certainty,” a thinly-veiled reference to Democrats’ demand that the Trump administration ease off its so-called “total war on wind” turbines.
In World Cup soccer, Turkey hasn’t faced Australia in more than a decade. But the two countries went head to head in the competition to host next year’s United Nations climate summit, COP31. Turkey won, Bloomberg reported last night. Australia’s defeat is a blow not just to Canberra but to those who had hoped a summit Down Under would set the stage for an “island COP.” The pre-conference leaders’ gathering is set to take place on an as-yet-unnamed Pacific island, which had raised hopes that the next confab could put fresh emphasis on the concerns of low-lying nations facing sea-level rise.
More than a dozen states where data centers are popping up could face electric power emergencies under extreme conditions this winter, a grid security watchdog warned this week, E&E News reported. The North American Electric Reliability Corporation listed New England, the Carolinas, most of Texas, and the Pacific Northwest among the most threatened regions. If those emergencies take place, the grid operators would need to import more electricity from other regions and seek voluntary power cutbacks from customers before resorting to rotating blackouts.

The United States is on the cusp of restarting a permanently shuttered atomic power plant for the first time. But anti-nuclear groups are making a last-ditch effort to block the revival. In a complaint filed Monday in the U.S. District court for the Western District of Michigan, a trio of activist organizations — Beyond Nuclear, Don’t Waste Michigan, and Michigan Safe Energy Future — argued that the plant should never have received regulatory approval for a restart. As I wrote in this newsletter at the time, the Nuclear Regulatory Commission granted plant owner Holtec International permission to go ahead with the restoration in July. Last month, the company — best known for manufacturing waste storage vessels and decommissioning defunct plants — received a shipment of fuel for the single-reactor station, as I reported here. While the opponents are asking the federal judge to intervene, state lawmakers in Michigan are considering new subsidies for nuclear power, Bridge Michigan reported.
Further north along Michigan’s western coastline, a coal-fired power plant set to close down in May got another extension from the Trump administration. In an order signed Tuesday, Secretary of Energy Chris Wright renewed his direction to utility Consumers Energy to hold off on shutting down the facility, which the administration deemed necessary to stave off blackouts. The latest order, Michigan Advance noted, extends until February 17, 2026. President Donald Trump’s efforts to prop up the coal industry haven’t gone so well elsewhere. As Heatmap’s Matthew Zeitlin reported last week, coal-fired stations keep breaking down, with equipment breaking at more than twice the rate of wind turbines.
Matthew had another timely story out yesterday: Members of the PJM Interconnection’s voting base of advisers met Wednesday to consider a dozen different proposals for how to bring more data centers online put forward by data center companies, transmission developers, utilities, state lawmakers, advocates, PJM’s market monitor, and PJM itself. None passed. “There was no winner here,” PJM chief executive Manu Asthana told the meeting following the announcement of the vote tallies. There was, however, “a lot of information in these votes,” he added. “We’re going to study them closely.” The grid operator still aims to get something to federal regulators by the end of the year.
Here’s a gruesome protocol that apparently exists when a toothed whale washes up. Federal officials arrived on Nantucket on Wednesday afternoon to remove a beached sperm whale’s jaw. Per the Nantucket Current: “This is being done to prevent any theft of its teeth, which are illegal to take and possess. The Environmental Police will take the jaw off-island.”
Members of the nation’s largest grid couldn’t agree on a recommendation for how to deal with the surge of incoming demand.
The members of PJM Interconnection, the country’s largest electricity market, held an advisory vote Wednesday to help decide how the grid operator should handle the tidal wave of incoming demand from data centers. Twelve proposals were put forward by data center companies, transmission companies, power companies, utilities, state legislators, advocates, PJM’s market monitor, and PJM itself.
None of them passed.
“There was no winner here,” PJM chief executive Manu Asthana told the meeting following the announcement of the vote tallies. There was, however, “a lot of information in these votes,” he added. “We’re going to study them closely.”
The PJM board was always going to make the final decision on what it would submit to federal regulators, and will try to get something to the Federal Energy Regulatory Commission by the end of the year, Asthana said — just before he plans to step down as CEO.
“PJM opened this conversation about the integration of large loads and greatly appreciates our stakeholders for their contributions to this effort. The stakeholder process produced many thoughtful proposals, some of which were introduced late in the process and require additional development,” a PJM spokesperson said in a statement. “This vote is advisory to PJM’s independent Board. The Board can and does expect to act on large load additions to the system and will make its decision known in the next few weeks.”
The surge in data center development — actual and planned — has thrown the 13-state PJM Interconnection into a crisis, with utility bills rising across the network due to the billions of dollars in payments required to cover the additional costs.
Those rising bills have led to cries of frustration from across the PJM member states — and from inside the house.
“The current supply of capacity in PJM is not adequate to meet the demand from large data center loads and will not be adequate in the foreseeable future,” PJM’s independent market monitor wrote in a memo earlier this month. “Customers are already bearing billions of dollars in higher costs as a direct result of existing and forecast data center load,” it said in a quarterly report released just a few days letter, pegging the added charges to ensure that generators will be available in times of grid stress due to data center development at over $16 billion.
PJM’s initial proposal to deal with the data center swell would have created a category for new large sources of demand on the system to interconnect without the backing of capacity; in return, they’d agree to have their power supply curtailed when demand got too high. The proposal provoked outrage from just about everyone involved in PJM, including data center developers and analysts who were open to flexibility in general, who said that the grid operator was overstepping its responsibilities.
PJM’s subsequent proposal would allow for voluntary participation in a curtailment program, but was lambasted by environmental groups like Evergreen Collaborative for not having “any semblance of ambition.” PJM’s own market monitor said that voluntary schemes to curtail power “are not equivalent to new generation,” and that instead data centers should “be required to bring their own new generation” — essentially to match their own demand with new supply.
A coalition of environmental groups, including the Natural Resources Defence Council and state legislators in PJM, said in their proposal that data centers should be required to bring their own capacity — crucially counting demand response (being paid to curtail power) as a source of capacity.
“The growth of data centers is colliding with the reality of the power grid,” Tom Rutigliano, who works on grid issues for the Natural Resources Defense Council, said in a statement. “PJM members weren’t able to see past their commercial interests and solve a critical reliability threat. Now the board will need to stand up and make some hard decisions.”
Those decisions will come without any consensus from members about what to do next.
“Just because none of these passed doesn’t mean that the board will not act,” David Mills, the chairman of PJM’s board of managers, said at the conclusion of the meeting. “We will make our best efforts to put something together that will address the issues.”
