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.

The administration has yet to publish formal documentation of its decision, leaving several big questions unanswered.
President Trump announced on Thursday that he was repealing the Environmental Protection Agency’s scientific determination that greenhouse gases are dangerous to human health and the natural world.
The signal move would hobble the EPA’s ability to limit heat-trapping pollution from cars, trucks, power plants, and other industrial facilities. It is the most aggressive attack on environmental regulation that the president and his officials have yet attempted.
The move, which was first proposed last summer, has major legal implications. But its importance is also symbolic: It brings the EPA’s official view of climate change much closer to President Trump’s false but long-held claim that anthropogenic global warming — which scientists have long affirmed as a major threat to public health and the environment — is in fact a “con job,” “a hoax,” and a “scam.”
While officials in the first Trump administration frequently sought to undermine climate regulation, arguing that the government’s climate rules were unnecessary or a waste of time and money, they did not formally try to undo the agency’s scientific determination that heat-trapping pollution was dangerous.
The move is only the most recent of a long list of attacks on environmental protections — including the partial rollback of the country’s first climate law, the Inflation Reduction Act, enacted last summer — that Trump and congressional Republicans have overseen since taking office last January.
The repeal has few near-term implications for utilities, clean energy companies, or automakers because the Trump administration has already suspended rules limiting air pollution from vehicles and the power sector. But it could shape the long-term direction of American climate and energy policy.
Several environmental and public health organizations, including the American Lung Association and the Environmental Defense Fund, have vowed to challenge the move in court.
If the Supreme Court eventually rules in favor of the Trump administration, then it would hamstring the ability of any future president — Republican or Democrat — to use the EPA to slow climate change or limit greenhouse gas pollution. The EPA has not yet published the legal documents formalizing the repeal.
Here is what we know — and don’t know — about the repeal for now:
Startups Airloom Energy and Radia looked at the same set of problems and came up with very different solutions.
You’d be forgiven for assuming that wind energy is a technologically stagnant field. After all, the sleek, three-blade turbine has defined the industry for nearly half a century. But even with over 1,000 gigawatts of wind generating capacity installed worldwide, there’s a group of innovators who still see substantial room for improvement.
The problems are myriad. There are places in the world where the conditions are too windy and too volatile for conventional turbines to handle. Wind farms must be sited near existing transportation networks, accessible to the trucks delivering the massive components, leaving vast areas with fantastic wind resources underdeveloped. Today’s turbines have around 1,500 unique parts, and the infrastructure needed to assemble and stand up a turbine’s multi-hundred-foot tower and blades is expensive— giant cranes don’t come cheap.
“We’ve only really ever tried one type of technology,” Neal Rickner, the CEO of the wind power startup Airloom Energy, told me. Now, he’s one of a few entrepreneurs trying a new approach.
Airloom’s system uses much-shorter vertical blades attached to an oval track that resembles a flat rollercoaster — no climbs or drops, just a horizontal loop composed of 58 unique parts. Wind propels the blades around the track, turning a vertical shaft that’s connected to an electricity-producing generator. That differs from conventional turbines, which spin on a vertical plane around a horizontal shaft, like a ferris wheel.
The system is significantly lower to the ground than today’s turbines and has the ability to capture wind from any direction, unlike conventional turbines, allowing for deployment in areas with shifting wind patterns. It promises to be mass manufacturable, cheap, and simple to transport and install, opening up the potential to build systems in a wider variety of geographies — everywhere from airports to remote or even mountainous regions.
Airloom’s CTO, Andrew Streett, brings a background in drone tech that Rickner said helped shape the architecture of Airloom’s blades. “It’s all known tech. And it’s not completely off the shelf, but Andrew’s done it on 17 other platforms,” he told me. Rickner himself spent years at GoogleX working on Makani, a now-defunct wind energy project that attempted to commercialize an airborne wind energy system. The concept involved attaching rotors to autonomous kites, which flew in high-altitude loops to capture wind energy.
That system ultimately proved too complicated, something Airloom’s founder Robert Lumley warned Rickner about a decade ago at an industry conference. As Rickner recalls, he essentially told him, “all of that flying stuff is too complicated. Put all that physics — which is great — put it on the ground, on a rail.” Rickner took the lesson to heart, and when Lumley recruited him to join Airloom’s team a few years ago, he said it felt like an ideal chance to apply all the knowledge he’d accumulated “around what it takes to bring a novel wind technology to a very stodgy market.”
Indeed, the industry has proven difficult to disrupt. While Airloom was founded in 2014, the startup is still in its early stages, though it’s attracted backing from some climate sector heavyweights. Lowercarbon Capital led its $7.5 million seed round in 2024, which also included participation from Breakthrough Energy Ventures. The company also secured $5 million in matching funds from the state of Wyoming, where it’s based, and a $1.25 million contract with the Department of Defense.
Things are moving now. In the coming months, Airloom is preparing to bring its pilot plant online in Wyoming, closely followed by a commercial demo. Rickner told me the plan is to begin construction on a commercial facility by July 4, the deadline for wind to receive federal tax credits.
“If you could just build wind without gigantic or heavy industrial infrastructure — cranes and the like —- you will open up huge parts of the world,” Rickner told me, citing both the Global South and vast stretches of rural America as places where the roads, bridges, cranes, and port infrastructure may be insufficient for transporting and assembling conventional turbines. While modern onshore installations can exceed 600 feet from the tower’s base to the blade’s tip, Airloom’s system is about a fifth that height. Its nimble assembly would also allow turbines to be sited farther from highways, potentially enabling a more “out of sight, out of mind” attitude among residents and passersby who might otherwise resist such developments.
The company expects some of its first installations to be co-located with — you guessed it — data centers, as tech giants are increasingly looking to circumvent lengthy grid interconnection queues by sourcing power directly from onsite renewables, an option Rickner said wasn’t seriously discussed until recently.
Even considering Trump’s cuts to federal incentives for wind, “I’d much rather be doing Airloom today than even a year ago,” Rickner told me. “Now, with behind-the-meter, you’ve got different financing options. You’ve got faster buildout timelines that actually meet a venture company, like Airloom. You can see it’s still a tough road, don’t get me wrong. But a year ago, if you said we’re just going to wait around seven years for the interconnection queue, no venture company is going to survive that.”
It’s certainly not the only company in the sector looking to benefit from the data center boom. But I was still surprised when Rickner pointed out that Airloom’s fundamental value proposition — enabling wind energy in more geographies — is similar to a company that at first glance appears to be in a different category altogether: Radia.
Valued at $1 billion, this startup plans to make a plane as long as a football field to carry blades roughly 30% to 40% longer than today’s largest onshore models. Because larger blades mean more power, Radia’s strategy could make wind energy feasible in low-wind regions or simply boost output where winds are strong. And while the company isn’t looking to become a wind developer itself, “if you look at their pitch, it is the Airloom pitch,” Rickner told me.
Will Athol, Radia’s director of business development, told me that by the time the company was founded in 2016, “it was becoming clear that ground-based infrastructure — bridges, tunnels, roads, that kind of thing — was increasingly limiting where you can deploy the best turbines,” echoing Airloom’s sentiments. So competitors in the wind industry teamed up, requesting logistics input from the aviation industry. Radia responded, and has since raised over $100 million as it works to achieve its first flight by 2030.
Hopefully by that point, the federal war on wind will be a thing of the past. “We see ourselves and wind energy as a longer term play,” Athol told me. Though he acknowledged that these have certainly been “eventful times for the wind industry” in the U.S., there’s also a global market eager for this tech. He sees potential in regions such as India and North Africa, where infrastructure challenges have made it tough to deploy large-scale turbines.
Neither Radia nor Airloom thinks its approach will render today’s turbines obsolete, or that other renewable resources will be completely displaced. “I think if you look at most utilities, they want a mix,” Rickner said. But he’s still pretty confident in Airloom’s potential to seriously alter an industry that’s long been considered mature and constrained to incremental gains.
“When Airloom is 100% successful,” he told me, “we will take a huge chunk of market share.”
On electrolyzers’ decline, Anthropic’s pledge, and Syria’s oil and gas
Current conditions: Warmer air from down south is pushing the cold front in Northeast back up to Canada • Tropical Cyclone Gezani has killed at least 31 in Madagascar • The U.S. Virgin Islands are poised for two days of intense thunderstorms that threaten its grid after a major outage just days ago.
Back in November, Democrats swept to victory in Georgia’s Public Service Commission races, ousting two Republican regulators in what one expert called a sign of a “seismic shift” in the body. Now Alabama is considering legislation that would end all future elections for that state’s utility regulator. A GOP-backed bill introduced in the Alabama House Transportation, Utilities, and Infrastructure Committee would end popular voting for the commissioners and instead authorize the governor, the Alabama House speaker, and the Alabama Senate president pro tempore to appoint members of the panel. The bill, according to AL.com, states that the current regulatory approach “was established over 100 years ago and is not the best model for ensuring that Alabamians are best-served and well-positioned for future challenges,” noting that “there are dozens of regulatory bodies and agencies in Alabama and none of them are elected.”
The Tennessee Valley Authority, meanwhile, announced plans to keep two coal-fired plants operating beyond their planned retirement dates. In a move that seems laser-targeted at the White House, the federally-owned utility’s board of directors — or at least those that are left after President Donald Trump fired most of them last year — voted Wednesday — voted Wednesday to keep the Kingston and Cumberland coal stations open for longer. “TVA is building America’s energy future while keeping the lights on today,” TVA CEO Don Moul said in a statement. “Taking steps to continue operations at Cumberland and Kingston and completing new generation under construction are essential to meet surging demand and power our region’s growing economy.”
Secretary of the Interior Doug Burgum said the Trump administration plans to appeal a series of court rulings that blocked federal efforts to halt construction on offshore wind farms. “Absolutely we are,” the agency chief said Wednesday on Bloomberg TV. “There will be further discussion on this.” The statement comes a week after Burgum suggested on Fox Business News that the Supreme Court would break offshore wind developers’ perfect winning streak and overturn federal judges’ decisions invalidating the Trump administration’s orders to stop work on turbines off the East Coast on hotly-contested national security, environmental, and public health grounds. It’s worth reviewing my colleague Jael Holzman’s explanation of how the administration lost its highest profile case against the Danish wind giant Orsted.
Thyssenkrupp Nucera’s sales of electrolyzers for green hydrogen projects halved in the first quarter of 2026 compared to the same period last year. It’s part of what Hydrogen Insight referred to as a “continued slowdown.” Several major projects to generate the zero-carbon fuel with renewable electricity went under last year in Europe, Australia, and the United States. The Trump administration emphasized the U.S. turn away from green hydrogen by canceling the two regional hubs on the West Coast that were supposed to establish nascent supply chains for producing and using green hydrogen — more on that from Heatmap’s Emily Pontecorvo. Another potential drag on the German manufacturer’s sales: China’s rise as the world’s preeminent manufacturer of electrolyzers.

The artificial intelligence giant Anthropic said Wednesday it would work with utilities to figure out how much its data centers were driving up electricity prices and pay a rate high enough to avoid passing the costs onto ratepayers. The announcement came as part of a multi-pronged energy strategy to ease public concerns over its data centers at a moment when the server farms’ effect on power prices and local water supplies is driving a political backlash. As part of the plan, Anthropic would cover 100% of the costs of upgrading the grid to bring data centers online, and said it would “work to bring net-new power generation online to match our data centers’ electricity needs.” Where that isn’t possible, the company said it would “work with utilities and external experts to estimate and cover demand-driven price effects from our data centers.” The maker of ChatGPT rival Claude also said it would establish demand response programs to power down its data centers when demand on the grid is high, and deploy other “grid optimization” tools.
“Of course, company-level action isn’t enough. Keeping electricity affordable also requires systemic change,” the company said in a blog post. “We support federal policies — including permitting reform and efforts to speed up transmission development and grid interconnection — that make it faster and cheaper to bring new energy online for everyone.”

Syria’s oil reserves are opening to business, and Western oil giants are in line for exploration contracts. In an interview with the Financial Times, the head of the state-owned Syrian Petroleum Company listed France’s TotalEnergies, Italy’s Eni, and the American Chevron and ConocoPhillips as oil majors poised to receive exploration licenses. “Maybe more than a quarter, or less than a third, has been explored,” said Youssef Qablawi, chief executive of the Syrian Petroleum Company. “There is a lot of land in the country that has not been touched yet. There are trillions of cubic meters of gas.” Chevron and Qatar’s Power International Holding inked a deal just last week to explore an offshore block in the Mediterranean. Work is expected to begin “within two months.”
At the same time, Indonesia is showing the world just how important it’s become for a key metal. Nickel prices surged to $17,900 per ton this week after Indonesia ordered steep cuts to protection at the world’s biggest mine, highlighting the fast-growing Southeast Asian nation’s grip over the global supply of a metal needed for making batteries, chemicals, and stainless steel. The spike followed Jakarta’s order to cut production in the world’s biggest nickel mine, Weda Bay, to 12 million metric tons this year from 42 million metric tons in 2025. The government slashed the nationwide quota by 100 million metric tons to between 260 million and 270 million metric tons this year from 376 million metric tons in 2025. The effect on the global price average showed how dominant Indonesia has become in the nickel trade over the past decade. According to another Financial Times story, the country now accounts for two-thirds of global output.
The small-scale solar industry is singing a Peter Tosh tune: Legalize it. Twenty-four states — funny enough, the same number that now allow the legal purchase of marijuana — are currently considering legislation that would allow people to hook up small solar systems on balconies, porches, and backyards. Stringent permitting rules already drive up the cost of rooftop solar in the U.S. But systems small enough for an apartment to generate some power from a balcony have largely been barred in key markets. Utah became the first state to vote unanimously last year to pass a law allowing residents to plug small solar systems straight into wall sockets, providing enough electricity to power a laptop or small refrigerator, according to The New York Times.
