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.

It starts — but doesn’t end — with the Strait of Hormuz.
For the second time in a year, the United States and Israel have launched a major aerial assault on Iran. Strikes were reported across the country early Saturday, targeting Iranian leadership and military infrastructure. In retaliation, Iran has launched attacks on Israel and Gulf nations allied with the U.S., with several of the targets appearing to be American military installations. “The United States military is undertaking a massive and ongoing operation,” President Trump said in a video posted to Truth Social explaining his rationale for launching the war.
While the conflict has quickly metastasized across the region, it has the potential to affect the entire world by disrupting the production and shipment of oil and natural gas.
Iran and its neighbors on the Persian Gulf are some of the largest oil and gas producers in the world and the country has long threatened to disrupt oil exports as an act of self-defense or retaliation from attack.
That may be already happening. According to data from Bloomberg, some oil tankers are pausing or turning around outside the vital Strait of Hormuz, a narrow, deep channel between Iran and Oman that connects the Persian Gulf to the Arabian Sea and thus to global markets in and bordering the Indian Ocean.
The strait has been “effectively closed,” according to a report from Tasnim, a semi-official news agency linked to the Iran Revolutionary Guard Corps. British naval officials also said they had “received multiple reports” of broadcasts that “have claimed that the Strait of Hormuz (SoH) has been closed.” And a European Union naval official told Reuters that the Iranian Revolutionary Guard had been broadcasting “no ship is allowed to pass the Strait of Hormuz” to ships in the area. Some tankers are still navigating the strait, according to marine tracking data from Kpler.
But it’s questionable whether Iran can actually maintain any attempted closure of the strait, whether by laying mines or directly threatening and attacking ships.
So far, U.S. attacks are “targeting, fairly heavily, naval assets and assets that are close to the Gulf,” Greg Brew, an analyst at the Eurasia Group, told me, which “suggests that they are trying to degrade Iran’s ability to disrupt energy traffic through the Strait of Hormuz.”
The U.S. is “trying to reduce the risks of Iranian effort to close the strait as part of this operation, rather than waiting to see if the Iranians escalate in that direction. The Iranians have responded by claiming that the strait has been closed. The problem for them now, though, is that they’ll have to enforce that threat.”
Closing the strait was a “tail risk” that had been roiling the oil market in the lead-up to Trump’s decision to launch the attack, Rory Johnston, petroleum analyst and author of Commodity Context, told me.
Global oil prices had gotten skittish over the past weeks, with the Brent crude benchmark getting as low at $66.30 per barrel in early February and getting near $73 per barrel on Friday. Brent prices approached $80 per barrel last June during the 12 Day War between Iran and Israel.
While the market could likely weather disruption to Iran’s own exports, jumpy behavior in the market was due to pricing in an enhanced risk of a region-wide calamity. Options traders especially were “attempting to hedge that enormous tail risk,” Johnston said, and “that was really moving the market.”
And even if the strait is not directly closed off by the Iranian military, ships may find it financially onerous to attempt the passage. “Insurers told ship owners on Saturday they would cancel policies and raise coverage prices for vessels travelling through the Gulf and Strait of Hormuz after the U.S. and Israel attacked Iran,” the Financial Times reported Saturday.
Another risk to the region’s oil sector is that Iran could retaliate by striking oil production and exporting infrastructure in neighboring countries, Johnston told me. “Right next door, you’ve got Iraq, you’ve got Saudi Arabia, and you’ve got the Emirates and others who collectively are more like 20 million barrels per day. And that is obviously a much bigger deal,” Johnston said, comparing their production to Iran’s own oil industry.
Of course, Iran is still a major exporter despite U.S. sanctions; in the days running up to the U.S. attack, it was shipping out around 3 million barrels per day from Kharg Island in the Strait of Hormuz, according to data from Bloomberg, almost triple its exports from equivalent dates in January and nearly its entire daily production.
Iran’s exports “had actually surged immediately ahead of what’s gone down over the past 24 hours,” Johnston told me. “In the past couple days, you’d seen a large surge of tankers departing Kharg Island, and the inventories on Kharg Island being drawn down, which is kind of what you would do if you expected that your exports were about to get disrupted.”
To the extent Iranian oil exports are cut off, that could be a big deal for China, which has become the number one destination for Middle East oil shipments. Beijing has been building up stockpiles of oil, likely preparing for the risk that sanctioned exporters like Iran and Venezuela would go off the market, as well as wider risks to exports from the Middle East.
“China is highly concerned over the military strikes against Iran,” the Chinese foreign ministry wrote on X. “China calls for an immediate stop of the military actions, no further escalation of the tense situation, resumption of dialogue and negotiation, and efforts to uphold peace and stability in the Middle East.”
Last year, China began to substantially increase its stockpiling of oil, going from 84,000 barrels per day to 430,000 barrels per day, some 83% of the growth of its imports, according to data and estimates from Rystad Energy and Erica Downs, a senior research scholar at the Columbia University Center on Global Energy Policy.
While the U.S. is now far less reliant on oil exports from the Middle East, oil and gas is still a global market. If Middle Eastern oil and gas exports are disrupted, that will likely increase the price of energy — whether it’s gasoline, electricity, or even home heating — as American energy producers can sell their barrels and BTUs at higher prices globally.
It’s either reassure investors now or reassure voters later.
Investor-owned utilities are a funny type of company. On the one hand, they answer to their shareholders, who expect growing returns and steady dividends. But those returns are the outcome of an explicitly political process — negotiations with state regulators who approve the utilities’ requests to raise rates and to make investments, on which utilities earn a rate of return that also must be approved by regulators.
Utilities have been requesting a lot of rate increases — some $31 billion in 2025, according to the energy policy group PowerLines, more than double the amount requested the year before. At the same time, those rate increases have helped push electricity prices up over 6% in the last year, while overall prices rose just 2.4%.
Unsurprisingly, people have noticed, and unsurprisingly, politicians have responded. (After all, voters are most likely to blame electric utilities and state governments for rising electricity prices, Heatmap polling has found.) Democrat Mikie Sherrill, for instance, won the New Jersey governorship on the back of her proposal to freeze rates in the state, which has seen some of the country’s largest rate increases.
This puts utilities in an awkward position. They need to boast about earnings growth to their shareholders while also convincing Wall Street that they can avoid becoming punching bags in state capitols.
Make no mistake, the past year has been good for these companies and their shareholders. Utilities in the S&P 500 outperformed the market as a whole, and had largely good news to tell investors in the past few weeks as they reported their fourth quarter and full-year earnings. Still, many utility executives spent quite a bit of time on their most recent earnings calls talking about how committed they are to affordability.
When Exelon — which owns several utilities in PJM Interconnection, the country’s largest grid and ground zero for upset over the influx data centers and rising rates — trumpeted its growing rate base, CEO Calvin Butler argued that this “steady performance is a direct result of a continued focus on affordability.”
But, a Wells Fargo analyst cautioned, there is a growing number of “affordability things out there,” as they put it, “whether you are looking at Maryland, New Jersey, Pennsylvania, Delaware.” To name just one, Pennsylvania Governor Josh Shapiro said in a speech earlier this month that investor-owned utilities “make billions of dollars every year … with too little public accountability or transparency.” Pennsylvania’s Exelon-owned utility, PECO, won approval at the end of 2024 to hike rates by 10%.
When asked specifically about its regulatory strategy in Pennsylvania and when it intended to file a new rate case, Butler said that, “with affordability front and center in all of our jurisdictions, we lean into that first,” but cautioned that “we also recognize that we have to maintain a reliable and resilient grid.” In other words, Exelon knows that it’s under the microscope from the public.
Butler went on to neatly lay out the dilemma for utilities: “Everything centers on affordability and maintaining a reliable system,” he said. Or to put it slightly differently: Rate increases are justified by bolstering reliability, but they’re often opposed by the public because of how they impact affordability.
Of the large investor-owned utilities, it was probably Duke Energy, which owns electrical utilities in the Carolinas, Florida, Kentucky, Indiana, and Ohio, that had to most carefully navigate the politics of higher rates, assuring Wall Street over and over how committed it was to affordability. “We will never waver on our commitment to value and affordability,” Duke chief executive Harry Sideris said on the company’s February 10 earnings call.
In November, Duke requested a $1.7 billion revenue increase over the course of 2027 and 2028 for two North Carolina utilities, Duke Energy Carolinas and Duke Energy Progress — a 15% hike. The typical residential customer Duke Energy Carolinas customer would see $17.22 added onto their monthly bill in 2027, while Duke Energy Progress ratepayers would be responsible for $23.11 more, with smaller increases in 2028.
These rate cases come “amid acute affordability scrutiny, making regulatory outcomes the decisive variable for the earnings trajectory,” Julien Dumoulin-Smith, an analyst at Jefferies, wrote in a note to clients. In other words, in order to continue to grow earnings, Duke needs to convince regulators and a skeptical public that the rate increases are necessary.
“Our customers remain our top priority, and we will never waver on our commitment to value and affordability,” Sideris told investors. “We continue to challenge ourselves to find new ways to deliver affordable energy for our customers.”
All in all, “affordability” and “affordable” came up 15 times on the call. A year earlier, they came up just three times.
When asked by a Jefferies analyst about how Duke could hit its forecasted earnings growth through 2029, Sideris zeroed in on the regulatory side: “We are very confident in our regulatory outcomes,” he said.
At the same time, Duke told investors that it planned to increase its five-year capital spending plan to $103 billion — “the largest fully regulated capital plan in the industry,” Sideris said.
As far as utilities are concerned, with their multiyear planning and spending cycles, we are only at the beginning of the affordability story.
“The 2026 utility narrative is shifting from ‘capex growth at all costs’ to ‘capex growth with a customer permission slip,’” Dumoulin-Smith wrote in a separate note on Thursday. “We believe it is no longer enough for utilities to say they care about affordability; regulators and investors are demanding proof of proactive behavior.”
If they can’t come up with answers that satisfy their investors, ultimately they’ll have to answer to the voters. Last fall, two Republican utility regulators in Georgia lost their reelection bids by huge margins thanks in part to a backlash over years of rate increases they’d approved.
“Especially as the November 2026 elections approach, utilities that fail to demonstrate concrete mitigants face political and reputational risk and may warrant a credibility discount in valuations, in our view,” Dumoulin wrote.
At the same time, utilities are dealing with increased demand for electricity, which almost necessarily means making more investments to better serve that new load, which can in the short turn translate to higher prices. While large technology companies and the White House are making public commitments to shield existing customers from higher costs, utility rates are determined in rate cases, not in press releases.
“As the issue of rising utility bills has become a greater economic and political concern, investors are paying attention,” Charles Hua, the founder and executive director of PowerLines, told me. “Rising utility bills are impacting the investor landscape just as they have reshaped the political landscape.”
Plus more of the week’s top fights in data centers and clean energy.
1. Osage County, Kansas – A wind project years in the making is dead — finally.
2. Franklin County, Missouri – Hundreds of Franklin County residents showed up to a public meeting this week to hear about a $16 billion data center proposed in Pacific, Missouri, only for the city’s planning commission to announce that the issue had been tabled because the developer still hadn’t finalized its funding agreement.
3. Hood County, Texas – Officials in this Texas County voted for the second time this month to reject a moratorium on data centers, citing the risk of litigation.
4. Nantucket County, Massachusetts – On the bright side, one of the nation’s most beleaguered wind projects appears ready to be completed any day now.
