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.

On the Greenhouse Gas Reduction Fund, Canada’s new prime minister, and CERAWeek
Current conditions: Firefighters successfully controlled brush fires in Long Island that prompted New York Gov. Kathy Hochul to declare a state of emergency • Brisbane, Australia, recorded its wettest day in more than 50 years • Forecasters are keeping an eye on a storm system developing across the central U.S. that could pack a serious punch this week.
The nonprofit Climate United filed a lawsuit over the weekend against the Environmental Protection Agency and Citibank for withholding $7 billion in climate funds awarded as part of the Biden administration’s Inflation Reduction Act. The move escalates a dispute over some $20 billion in grants from the IRA’s Greenhouse Gas Reduction Fund, which was designed to help mobilize private capital toward clean energy and climate solutions. President Trump’s EPA Administrator Lee Zeldin has been on a mission to claw back the funds, claiming their distribution was rushed and mismanaged. In its lawsuit, Climate United says it has been unable to access the $7 billion it was awarded, and that the EPA and Citibank have given no explanation for this. It wants a judge to order that the money be released. “We’re not trying to make a political statement here,” Beth Bafford, chief executive of Climate United, toldThe New York Times. “This is about math for homeowners, for truck drivers, for public schools — we know that accessing clean energy saves them money that they can use on far more important things.” The Trump administration has reportedly demanded that the eight organizations tapped to receive the money turn over records to the FBI and appear in federal court later this month.
Canada’s Liberal Party has elected Mark Carney, a net-zero finance advocate, to succeed Justin Trudeau as prime minister. Carney is not a career politician. Instead, he comes from the financial world, having overseen both the Bank of Canada and the Bank of England, and is an evangelist for green investment and a net-zero financial sector. He was the UN Special Envoy for Climate Action and Finance in 2019, and “has made clean energy, climate policies and economic prosperity for Canada some of the central facets of his campaign,” CNN reported. If he wins the upcoming general election, Carney will be tasked with navigating President Trump’s tariffs and making key decisions about the future of Canada’s vast natural resources, including fossil fuels and rare minerals.
The U.S. has withdrawn from yet another global climate initiative, this one aimed at helping developing nations recover from natural disasters. The United Nations loss and damage fund was one of the biggest wins to come out of COP28 in 2023, with nearly 200 countries signing on in support. It’s expected to start funding projects this year. About $740 million has been pledged so far, and the U.S. has said it will give about $17.5 million, though it’s unclear if that money will actually be handed over now. “This decision, made by the nation with the largest historical responsibility for climate change, jeopardises vital support for vulnerable countries facing irreversible climate impacts,” said Ali Mohamed, the chair of the African Group of Negotiators.
The energy industry descends on Houston, Texas, this week, for the annual CERAWeek conference. This year’s event, titled “Moving Ahead: Energy Strategies for a Complex World,” will focus on the changing global energy landscape. Key themes include shifting regulations, the turbulent oil and gas market, electrification and power demand, the rise of AI, managing emissions, and the policy outlook for renewables. According toReuters energy columnist Ron Bousso, fossil fuel executives are going into the conference with a case of “Trump buyer’s remorse” as new tariffs and geopolitical policies from the Trump administration have “created turmoil in financial markets and clouded the outlook for the global economy and energy prices.”
Argentina will observe three days of national mourning after 16 people were killed in flash flooding over the weekend triggered by unprecedented rainfall. Nearly a year’s worth of rain – about 16 inches – fell in just eight hours in the port city of Bahia Blanca in the Buenos Aires province. Many people are still missing. Environment official Andrea Dufourg said the event was a clear example of climate change. “Unfortunately this will continue to take place,” Dufourg said. “We have no other option than to prepare cities, educate citizens, and establish effective early warning systems.”
Twenty-one House Republicans have signed a letter urging the GOP to uphold the Inflation Reduction Act’s clean energy tax credits in their budget bill, warning that gutting the credits would “risk sparking an energy crisis in our country, resulting in drastically higher power bills for American families.” That’s three more than signed a similar letter during the last Congress.
While they’re getting more accurate all the time, they still rely on data from traditional models — and possibly always will.
The National Oceanic and Atmospheric Administration has had a bruising few weeks. Deep staffing cuts at the hands of Elon Musk’s efficiency crusaders have led to concerns regarding the potential closure of facilities critical to data-gathering and weather-forecasting operations. Meteorologists have warned that this could put lives at risk, while industries that rely on trustworthy, publicly available weather data — from insurance to fishing, shipping, and agriculture — are bracing for impact. While reliable numbers are difficult to come by, the agency appears to have lost on the order of 7% to 10% of its workforce, or more than 1,000 employees. NOAA’s former deputy director, Andrew Rosenberg, wrote that Musk plans to lay off 50% of the agency, while slashing its budget by 30%.
Will that actually happen? Who the heck knows. But what we can look at are the small cracks that are already emerging, and who could step in to fill that void.
One thing that’s certain is that the National Weather Service, a division of NOAA, announced last week that it is suspending operations at a weather balloon launch site in Alaska, due to staffing shortages. The data gathered at this remote outpost helped inform the agency’s weather forecasts, which are relied upon by hundreds of millions of people, as well as many of the world’s largest companies and public agencies.
Perhaps to Musk’s department, this looks like a prime opportunity for the private sector to step up and demonstrate some nimble data gathering prowess — and indeed a startup that I’ve covered before, WindBorne, has already offered its services. The company, which makes advanced weather balloons, has offered to provide NOAA with data from its own Alaska launches for six months, at no cost. WindBorne is also one of a number of private companies creating AI-based weather models that have outperformed NOAA’s traditional, physics-based models on key metrics such as temperature, wind speed and direction, precipitation, humidity, and pressure.
All this raises the question, though, of what kind of role the private sector could and should play in the weather forecasting space overall. If the architects of Project 2025 have their way, NOAA would be “broken up and downsized,” and its National Weather Service division would “fully commercialize its forecasting operations.” If the Trump administration achieves these goals, “the Weather Service would cease to function in a way that it could meet its mandate to protect American life and property,” Daniel Swain, a climate scientist at University of California Agriculture and Natural Resources, told me.
But given that heavyweights like Google, Huawei, and Nvidia are already in the AI-based weather prediction game, along with startups such as WindBorne and Brightband, which is making weather predictions tailored to the needs of specific industries such as insurance, agriculture, or transportation, it wasn’t clear to me whether, if NOAA were to crumble, the accuracy of weather forecasts necessarily would, too. I thought that perhaps Musk, the White House’s most notorious AI enthusiast, might be thinking the same thing. So I asked around.
“There’s actually a very good argument that I think would be very uncontroversial to expand the role of the private sector, even to offload certain parts of the workflow to the private sector,” Swain told me, with regards to NOAA and its adoption — or lack thereof — of AI-based weather forecasting. But what nobody wanted was to get rid of free, publicly available government forecasts completely.
“I don’t want to have to figure out what company to trust. I just want to be able to go and open the National Weather Service and know what’s going on,” John Dean, the CEO and co-founder of WindBorne, told me.
Julian Green, the CEO and co-founder of Brightband, agreed. “The government doesn’t just forecast the weather, but it gives people alerts. And there’s regulation around whether [it tells you that] you should evacuate, or shut your factory down, or so on.” It’s not hard to imagine the ethical quandaries that could arise from a private company with a profit motive deciding who can access potentially life-saving forecasts, and for how much.
WindBorne’s and Brightband’s AI models, as well as those from tech giants such as Google, are significantly less computationally intensive to operate than those from NOAA or the other leading weather forecasting agency, the European Center for Medium-Range Weather Forecasts. These traditional models rely on supercomputers crunching complicated atmospheric equations based on the laws of physics to make their predictions.
But this doesn’t mean the physics-based models are getting replaced by AI now, or potentially ever. Government data and traditional forecasts still make up the backbone of advanced AIs, which are trained on decades of data largely gathered by NOAA satellites, weather balloons, and radar systems, and then interpreted through the lens of standard physics-based models. After training is complete, the AI models can predict what weather patterns will develop, much like ChatGPT predicts the next word in a sequence, but only after being fed a snapshot of initial weather conditions — also pulled from traditional physics-based models.
Essentially, these AI forecasts are built on the backs of the giants, and while their outcomes are hugely promising, they could not exist without that solid foundation. While one day, it might be possible to operate AI forecasting models without relying on traditional models, Dean and Green told me that physics-based models might always be critical for training the AI. So while their companies’ respective models have yielded impressive results, both Dean and Green nixed the idea that their companies could wholly replace the predictions made by the National Weather Service.
All of this is in flux of course, but as Green put it to me in an email, “a good mechanic doesn't throw away good older tools just because you get new tools.” Plus, as Dean explained, there are still conditions under which physics-based models tend to outperform AI, such as “really small-scale and high-res phenomena — let’s say convective events, let’s say severe thunderstorms in the Plains, or tornado formation.”
Even Project 2025’s authors point out that private industry forecasters rely on publicly available NOAA data, though it doesn’t make any reference to AI models or physics models. The document simply says that the agency “should focus on its data-gathering services” and the “efficient delivery of accurate, timely, and unbiased data to the public and to the private sector.”
There are also questions around whether AI models, trained on data from the past, will be able to predict the types of unusual and extreme weather events that are becoming more and more common in a warming world, Swain told me. “Does it fully capture those?” he asked. “There’s a lot of evidence that the answer is no.”
Lastly, NOAA’s weather model, the Global Forecast System, is simply measuring much more than the AI models do today. “It predicts so many different phenomena, like different types of snow, hail, mixing ratios, turbulence,” Dean said. “We’re building up over time to add more and more variables. But for both WindBorne and other models, it’s not the same currently as what GFS does.”
So while the Heritage Foundation might want to delegate all forecasting responsibilities to private companies, the vision I heard from the startups I talked to looked more like a mutually beneficial arrangement than the full commercialization of weather prediction, or even a clean division of labor. “It’s not privatized weather, it’s a public-private partnership,” Dean said of his ideal future, “where you get freely available forecasts from a public institution like NOAA, but they work with our industry to iterate faster and to drive more innovation.”
What everyone seems to want is simply for the government to forecast better, and today that means moving quickly to build AI-based models. NOAA has taken some steps forward, prototyping some models, bolstering its computing capabilities, and even recently partnering with Brightband to optimize its observational data to train AI models. But it remains behind other agencies in this regard. “The Chinese government and the European Center for Medium Range Weather Forecasts have done a far better job at adopting AI-based weather forecasts than NOAA has,” Dean told me. “So something does need to change at NOAA to get them to move faster.”
Indiscriminately laying off hundreds of the agency’s employees may not be the best place to start. But if there’s anything we know Musk loves, it’s AI and private sector ingenuity. So maybe, just maybe, this administration will be able to forge the kind of partnerships that can supercharge federal forecasting, while keeping NOAA’s weather predictions free and open for all. Or maybe we’ll all just be paying the big bucks to figure out when a hurricane is going to hit.
On energy transition funds, disappearing butterflies, and Tesla’s stock slump
Current conditions: Australians have been told to prepare for the worst ahead of Cyclone Alfred, and 100,000 people are already without power • Argentina’s Buenos Aires province has been hit by deadly flooding • Critical fire conditions will persist across much of west Texas through Saturday.
Many foreign aid programs have reportedly received a questionnaire from the Trump administration that they must complete as part of a review, presumably to help the government decide whether or not the groups should receive any more federal funds. One of the questions on the list, according toThe New York Times, is: “Can you confirm this is not a climate or ‘environmental justice’ project or include such elements?” Another asks if the project will “directly impact efforts to strengthen U.S. supply chains or secure rare earth minerals?” President Trump issued an executive order freezing foreign aid on his first day back in office. The Supreme Court subsequently ruled that aid must be released. The Times notes that “many of the projects under scrutiny have already fired their staff and closed their doors, because they have received no federal funds since the review process ostensibly began. … Within some organizations, there are no staff members left to complete the survey.”
The United States has withdrawn from a global financing program aimed at helping poorer nations ditch fossil fuels and shift to clean energy. A spokesperson from the Treasury Department said the Just Energy Transition Partnership does not align with President Trump’s vision of American economic and environmental values. The program was launched in 2021 and has 10 donor nations, including many European countries. Its first beneficiaries were Indonesia, Senegal, South Africa, and Vietnam. The U.S. had committed more than $3 billion to Indonesia and Vietnam and nearly $2 billion to South Africa under the initiative. “The U.S. withdrawal is regrettable,” said Rachel Kyte, the U.K.’s climate envoy. “The rest of the world moves on.” In January, the Trump administration canceled $4 billion in pledges to the Green Climate Fund. “We have to plan for a world where the U.S. is not transfusing funds into the green transition,” Kyte added.
Butterfly populations in the U.S. are rapidly declining due to a combination of climate change, habitat loss, and pesticide exposure, according to a “catastrophic and saddening” new study published in the journal Science. “Butterflies are vanishing from the face of the earth,” one of the study’s co-authors told The Washington Post. The research analyzed data from 77,000 butterfly surveys and found that butterfly numbers have fallen by 22% in just 20 years across the entire country. Of the 342 butterfly species that could be analyzed for trends, 107 plummeted by more than 50% and 22 by more than 90%. Just nine species saw their numbers rise. The researchers say these numbers are likely an underestimate.
The findings underscore the crisis facing all the small, underappreciated insects that pollinate flowers and crops, control pests, maintain soil health, and play a vital role in the food chain. According to the World Wildlife Fund, up to 40% of the world’s insect species may disappear by the end of the century. The study’s lead author, ecologist Collin Edwards, said there is some hope. “Butterflies have fast life cycles,” he said. “At least one generation per year, often two or three. And each of those generations lays a ton of eggs. This means that if we make the world a more hospitable place for butterflies, butterfly species have the capacity to respond very quickly and take advantage of all our efforts.”
The Government Accountability Office yesterday said that Congress can’t review (or repeal) the Environmental Protection Agency’s waiver that lets California set its own vehicle emissions standards. The decision derails plans being spearheaded by Republicans and EPA Administrator Lee Zeldin to use the congressional review process to overturn the waiver. California’s aggressive emissions standards, which have been adopted by many other states, would effectively end the sale of fully gas-powered cars by 2035. Republicans are mulling their next move.
Tesla’s stock price has been taking a beating as resentment grows around CEO Elon Musk’s political meddling. The company’s valuation soared from around $800 billion to $1.5 trillion in December, when it became clear Musk would become the president-elect’s right hand man. Since that moment, the company’s value has fallen by more than $600 million, effectively erasing the bump in Tesla’s market cap. Shares fell by 5.6% yesterday alone, and sales are cratering abroad and in key U.S. markets like California.
As Andrew Moseman explains for Heatmap, a big drop in sales could be a double-whammy for Tesla revenue. “Recall that the company’s most reliable revenue stream is not really its sales of electric cars, but rather the carbon credits generated by those EVs under California’s auto emissions regulatory scheme, which it can sell to other automakers who’ve yet to meet their emissions targets,” Moseman says. “Tesla’s tumbling sales in the wake of Musk’s antics could reduce the amount of credits it could sell to others, since the credits are tied to sales of low-emissions vehicles.” There was more bad news for Musk today: A SpaceX Starship rocket exploded during a test flight, sending flaming debris flying across a large area and disrupting air traffic in Florida.
A new report shows that a year after London expanded its low-emissions zone, air quality in the city has improved, with nitrogen dioxide levels across 2024 down significantly:
