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 third anniversary of the signing of the Inflation Reduction Act, Heatmap contributor Advait Arun mourns what’s been lost — but more importantly, charts a path toward what comes next.
Today, the Inflation Reduction Act would have turned three years old — if it hadn’t been buried alive in a big, beautiful grave. While the IRA was a hodgepodge of programs salvaged from President Biden’s far more ambitious Build Back Better agenda, it still represented the biggest climate investment in U.S. history. It catalyzed over $360 billion in energy and manufacturing investments and was expected to drive the installation of over 155 gigawatts of new solar and wind energy by 2030. And now Republicans have taken a sledgehammer to its achievements.
The timing could not be worse — not just for the climate, but also for the energy systems that we rely on. At a moment when the energy sector requires $1.4 trillion worth of upgrades by 2030 just to keep up with rising energy demand and increasingly erratic weather, Republicans have instead delivered a one-two punch of tariffs and tax hikes, sabotaging the industrial base required to deliver those investments and raising the retirement age of our power generation fleet.
All over the country (Texas and California maybe exempted), our aging electricity system is putting in its two-weeks notice. Staring down the barrel of precipitous demand growth, the country’s regulated utilities have requested over $29 billion in rate increases, concentrated across the West and South. The Department of Energy ordered the delayed retirement of coal plants and oil generators to manage this summer’s demand peaks. Meanwhile, capacity market prices on two of the country’s largest grids, PJM and MISO, have reached record highs ― a cry for new supply that is now increasingly unlikely to materialize quickly or cheaply. Two months ago, an unplanned nuclear reactor outage on a congested part of Louisiana’s energy grid plunged 100,000 people in and around New Orleans into a blackout. That meant no working AC or refrigerators across large swaths of the city during a sweltering Memorial Day weekend.
All of this amounts to an opening for Democrats to shift public opinion decisively in favor of renewed climate action. Moving forward, lawmakers cannot ignore our infirm fossil-fired energy system, which stands to thwart their ability to deliver affordability, employment, health, and resilience to their constituents. Despite our recent losses, we still need an energy policy ― a climate policy.
What should the Democrats’ second attempt at a clean investment program look like? Having delivered the Bipartisan Infrastructure Law and the Inflation Reduction Act, laws that committed the state to the realization of a particular energy future, Democrats are well-positioned to build on their successes, and even to engage Republicans who remain interested in supporting innovative technologies, decarbonizing industry, and protecting public lands.
Where they cannot meet Republicans halfway, Democrats should double their ambitions. They must continue to embrace the power of federal investment to shape markets and achieve policy goals. But they must also learn from the shortcomings of their previous legislative outings and substantively change how the federal government invests in the first place. The way forward for Democrats starts with mapping out exactly how far they didn’t go, and ends with going there.
IRA and BIL were paradigm-shifting attempts at market-shaping. They laid the groundwork for the deployment of promising clean firm energy technologies such as next-generation geothermal and nuclear energy, as well as for necessary grid and supply chain upgrades, such as long-distance transmission corridors and critical minerals processing.
IRA and BIL were not, however, a comprehensive climate policy. They created cost-share programs for infrastructure resilience but neglected to buttress municipal bond markets, which states and local governments can use to make longer-term investments in climate resilience and adaptation. They penalized methane emissions but organized no comprehensive or compulsory managed phaseout of fossil fuel infrastructure. They failed to advance or adequately finance a coordinated deployment strategy for any key energy sector. And they shed the transformative vision of Biden’s Build Back Better agenda, which sought to stabilize the cost of living for Americans in the meantime — a tactical retreat that, in retrospect, looks ill-advised given voters’ current worries about affordability.
I am aware that criticizing BIL and IRA on these grounds amounts to judging them for goals they didn’t attempt to achieve. Judging them by the goals they did attempt to achieve, however, reveals that they only ever worked incompletely. Taken together, BIL and IRA expanded the energy tax credit system, created powerful programs for piloting and deploying innovative energy technologies, and seeded an ecosystem of regional financing institutions devoted to more equitably distributing the benefits of decarbonization. But the energy tax credits were never expansive enough; the programs intended to motivate investments into deeper decarbonization were not flexible enough to drive the mass uptake of emerging technologies; and efforts to decarbonize disadvantaged communities lacked a coherent strategy and ran headlong into local capacity constraints.
Speeding up the energy transition and building new infrastructure at scale requires endowing federal and state agencies with adequate appropriations, access to liquidity, and crystal-clear, wide-ranging mandates, as well as empowering them in statute with considerable flexibility as to the financial products and strategies they deploy to achieve those mandates.
Although imperfect, the IRA’s tax credits scored some significant wins that should undoubtedly inform future policy. The law took an existing system of technology-specific subsidies that had been on the books in some form since 1978 and made them technology-neutral, allowing developers of nearly any zero-emissions energy technology to access tax relief. It expanded the credits to domestic manufacturers of certain low- and zero-carbon technologies. It created a tax credit transfer market, allowing developers with limited tax liability to sell their credits for cash on an open market to any tax-liable buyer, rather than engage in expensive and complex “tax equity” transactions with a few large banks. It made certain credits directly accessible to tax-exempt entities, significantly broadening the pool of potential users. And most of these credits remained entirely uncapped ― a “bottomless mimosa” for developers that spurred over $321 billion in clean energy and manufacturing investments and supported more than 2,000 new facilities across the country.
To be sure, the IRA did not level the playing field perfectly across developers or across technologies. Developers of energy transmission, grid transformers, and electric rail were shut out of the credits. Tax-exempt public and nonprofit developers ― entities as large as the New York Power Authority and as small as local churches ― could not monetize depreciation or participate in the transfer market. And some credits remained capped, forcing developers to apply and cross their fingers. But as early as 2023, Goldman Sachs argued that even with these inadequacies ― which have easy legislative and statutory fixes ― the IRA would still have spurred over $3 trillion in investment by 2033.
The GOP has gutted much of this system, shortcomings and all, and replaced it with a tangle of red tape. The energy tax credits are once again technology-specific ― solar and wind developers have a few months left to start a project and claim the credits as written, though what it means to start a project got more complex just yesterday. But even the “clean firm” energy technologies that can still claim credits until 2032, such as nuclear and geothermal, may not be safe under new “foreign entity of concern” rules, which condition credits on developers’ ability to limit their reliance on Chinese suppliers and investment, requiring them to map out their supply chains at an unprecedented level of detail.
Democrats seeking to restore and build upon this plank of the IRA have their work cut out for them. The developers and manufacturers of any technology that contributes to zero-emissions energy production should be able to access and monetize federal support regardless of their tax status and free from the rigmarole and uncertainties imposed by competitive application procedures. Goldman Sachs’ $3 trillion estimate is now the lower bound of what’s possible — for instance, a tax credit for transmission investments suggested as part of Build Back Better but excluded from the IRA could have catalyzed over $15 billion in investment and supported the economics of all other energy projects. To the degree that the tax credits can help build industrial capacity and institutional support for decarbonization, future policymaking should maximize their remit and their distribution.
Tax credits alone, however, are hardly a skeleton key to decarbonization. Being disbursed only once a project is complete, tax credits do not substitute for the kinds of upfront financial support that project developers — especially developers of emerging technologies — require to complete their projects in the first place. Private investors have been comfortable with solar, batteries, and onshore wind because these projects can be completed, claim their tax credits, and earn revenues on the grid on a mostly predictable timetable. But new nuclear reactors, geothermal, hydrogen, green steel, and carbon capture are unfamiliar investments, have uncertain development pathways and return profiles, and thus remain un-bankable to investors.
This is why BIL and IRA created powerful programs worth tens of billions of dollars to finance the deployment of emerging clean technologies and break this vicious cycle of uncertainty. The Office of Clean Energy Demonstrations, or OCED, and the Loan Programs Office, or LPO, in particular, were empowered to support, at scale, the testing and commercialization of these emerging technologies as well as conversions of whole electricity grids.
OCED, with over $27 billion in appropriations, set up hubs for hydrogen and carbon capture projects across the country, and funded a suite of advanced steel and iron decarbonization projects. Endowed by BIL and IRA with over $15 billion in total credit subsidy and well over $300 billion in total loan authority, LPO made ambitious investments across a host of innovative technology categories, including ― but certainly not limited to ― energy storage, sustainable aviation fuels, virtual power plants, EV charging, and bioenergy. At the end of 2024, the LPO had over 200 loan applicants in its queue.
By rescinding OCED’s unobligated funding, ambiguously rewriting LPO’s lending authorities (while rescinding most of its unobligated credit subsidy), and pulling the plug on billions of dollars worth of conditional commitments, the GOP has stopped years of progress in its tracks. In the meantime, LPO has shed considerable staff while the administration has prevented it from making any new commitments. The combination of the “foreign entity of concern” rules constraining tax credit eligibility and this shuttering of federal financing opportunities could seriously throttle the development and commercialization of nuclear energy in particular, the darling du jour of Republicans’ energy strategy.
If these offices were once the engines of decarbonization, they needed a stronger spark plug. The LPO, in particular, has a special authority to finance state government-backed, non-innovative clean energy projects, such as regional battery manufacturing clusters or a state power developer’s renewables portfolio, but has never used it. And while OCED and LPO can provide developers with some degree of upfront support, LPO cannot easily provide construction loans, cannot derisk project cash flows to provide security to investors, and cannot mandate offtake. These deficiencies prevent ambitious borrowers with unproven technologies from scaling up: they scare off private lenders in the infrastructure sector, many of which are skittish about construction risk, require project developers to demonstrate three to five years of stable cash flows, have a low tolerance for market price uncertainty, and have shareholders who demand a certain level of returns.
The DOE can bridge this “valley of death” by using its broader market-shaping authorities to take a more aggressive “dealership” role in these sectors, providing stable offtake for developers through upfront purchasing while becoming a reliable source of supply to downstream customers (like an actual car dealership or a grocery store). The DOE has in fact already used this approach to provide demand-side support to its now-endangered hydrogen hubs through OCED.
These kinds of public dealership arrangements are not unique or path-breaking: The Federal Reserve’s backstop of the municipal bond market in 2020, nonprofit investor Climate United’s planned EV trucking purchase-and-lease program in California, and even the Department of Defense’s recent MP Materials deal are all examples of public entities addressing a mismatch in the supply of and demand for a critical good and, in doing so, shaping markets toward public ends.
For all that BIL and IRA built avenues for developing and deploying energy technologies, they were also full of programs aimed at distributing the fruits of decarbonization equitably. Both the energy community bonus credits, a provision in the IRA that increased the value of the energy tax credits for projects in poorer, higher-unemployment, and energy facility-adjacent communities, and President Biden’s Justice40 initiative, which directed 40% of federal spending toward poorer and more rural communities, exemplified the administration’s “place-based” approach to industrial policy and economic development. The Biden administration heavily encouraged disadvantaged communities, local governments, schools, nonprofits, and tribal nations to develop their own clean energy projects — aided by the IRA’s direct pay mechanism, which allowed tax-exempt entities to access subsidies — by drawing on the various local decarbonization programs in BIL and IRA.
The Greenhouse Gas Reduction Fund, perhaps the most important of these programs, exemplifies the promises and pitfalls of the administration’s approach to “place-based” industrial policy. Managed by the Environmental Protection Agency, GGRF provided $27 billion to disadvantaged communities for the financing of rooftop solar, zero-emissions transport, and net-zero housing. That pot was split into three thematic buckets ― $7 billion to the Solar for All program, specifically for rooftop solar development; $14 billion to the National Clean Investment Fund, for supporting clean energy project finance more broadly in disadvantaged communities; and $6 billion more to local and regional technical assistance providers. Each program then subdivided its appropriations further. Solar for All went to 60 recipients across the country via a competitive application. The National Clean Investment Fund’s $14 billion was split among three awardees, each a coalition of various financial institutions designed to lend to energy projects, such as green banks, impact investors, and nonprofits ― and each of those recipient coalitions planned to subdivide much of its funds still further, first among coalition partners and then to subordinate local and state partners.
That dizzying program structure was meant to endow local communities with the ability to finance their own projects. And by including so many nonprofit institutions, GGRF could make significant inroads into Republican states, whose officials might otherwise reject federal funding.
But there was not much coordination between partners and subawardees around how best to deploy those funds. And what seemed like a firehose of financing often reached local recipients as a trickle of pre-development and technical assistance grants. Demanding that local organizations build their own capacity to plan, finance, and develop projects (or hire expensive external consultants to do so) ― with limited and one-time funds, no less ― is duplicative and inefficient, and it defeats GGRF’s own stated goal of mobilizing private capital through building standardized markets for decarbonization, thereby slowing down the pace of emissions reductions. The program’s complexity also left it vulnerable to EPA Administrator Lee Zeldin’s efforts to hound the program in court and freeze its funding.
Pandemic-era proposals for a National Investment Authority, as well as legislative proposals for a national green bank ― predecessors to the GGRF ― differ sharply from this status quo, instead highlighting how public finance can benefit from economies of scale. Larger financial institutions tasked with deploying clean energy projects can more easily prepare portfolios of projects for co-investors, engage with utilities, raise debt on municipal bond markets, and build a bench of trustworthy private developers to contract for projects. If they are publicly administered, these institutions can also take more risk, undercut private lenders, support more developers, engage with local communities to meet their needs, and use revenues from higher-return projects to derisk lower-return projects that might be necessary to build to achieve their resilience and affordability goals.
Should policymakers get a second shot at building a national green bank system, they should not try to recreate GGRF’s fractal approach to energy finance. Rather, policymakers must ensure that financing sits in the hands of public agencies that already have the authorities and expert staff to be ambitious market-shapers: bond banks, state-led energy finance authorities, and public developers. The good news is that state-level green banks empowered with state funding and a political mandate are already exercising their capacities to shape markets and support disadvantaged communities directly: the New York Power Authority, the Minnesota Climate Innovation Finance Authority, the Connecticut Green Bank, and the Greater Arizona Development Authority, to name a few, are all taking it upon themselves to raise debt and contract with developers to undertake ambitious energy and infrastructure investment programs.
But Democrats should be clear-eyed about the consequences of this reorientation: It means rejecting the prevailing wisdom that local nonprofits should necessarily coordinate local project development. Local groups can be extremely effective advocates for communities’ needs ― but in contrast to public investment agencies, their capacity to finance and implement solutions is simply not great enough.
This analysis of IRA and BIL leaves out more parts of the laws than it includes ― to take just one example, the BIL’s $5 billion National Electric Vehicle Infrastructure charging station program. But the story is similar: Ambitious as it seemed, NEVI money could only flow when state governments set up implementation offices and had their spending plans approved by federal officials. Most states, which had not prepared for any of this, took years to build the requisite capacity ― just in time for the Trump administration to try and snatch away the funding (though it recently admitted defeat in that project). In fairness to state governments, the EV charging sector is incredibly new. But even this program highlights how IRA and BIL lacked the capacity to be implemented as quickly and efficiently as their supporters hoped.
Going above and beyond BIL and IRA to deliver an energy policy that stabilizes Americans’ cost of living while driving an energy transition away from fossil fuels and toward the technologies of the future ― Democrats should embrace this challenge. But they should also be aware that climate ambition runs headlong into the same institutional problems facing American democracy at large. The Senate filibuster prevents either party from comprehensively redesigning the federal government, its institutions, and its regulations to serve Americans more quickly and more efficiently. That leaves both parties reliant on budget reconciliation ― to our detriment. The head-spinning design of GGRF was itself an artifact of the reconciliation process, which prevented Congress from creating a single green bank institution or giving it a specific mandate; its awardee organizations and coalitions certainly did not ask for the program structure they got.
There’s a lot more that budget reconciliation will never solve: the century-old American utility system, the regulatory thicket of U.S. electricity markets, or the land use and permitting rules that constrain project development and grid interconnection. And things could get worse: Trump-appointed judges and Supreme Court justices who reject federal agencies’ and state governments’ attempts to regulate fossil fuel infrastructure have placed the legal system itself at odds with responsible energy system management. The courts may no longer be able to block clawbacks and recissions of legally obligated federal spending. Democrats, like clean energy developers, do not fight on a level playing field.
While Democrats are out of federal power, they should practice ambitious climate policymaking at the state level. States already have considerable ability to raise finance and build capacity for ambitious infrastructure projects ― and they might have to quickly, considering the drain of federal capacity that might support them. By developing their own public programs for transmission finance, utility-scale battery procurement, virtual power plants, and clean firm energy pilots, Democratic state governments can ensure that the ecosystem of clean energy developers created by BIL and IRA does not disappear for lack of demand — and in doing so, these states would help stabilize the cost of clean energy project development.
Finally, Democrats should not forget that climate remains a cost of living issue. In a city like New Orleans, rocked by the recent nuclear outage, residents spend, on average, over 19% of their incomes on their energy bills, over three times the DOE’s threshold to be considered an energy-burdened community. Their bills already include adders for climate adaptation and disaster preparedness ― yet, for all they spend, they still face blackouts, and their costs will only increase as their grid continues to deteriorate. Here, climate policy is not about combating Chinese supply chain dominance, or even about delivering an American industrial renaissance. It’s about keeping the lights on, keeping bills low, keeping the air clean, and keeping residents safe from disaster.
It turns out that voters all over the country still care about these goals. A majority of likely voters in the next election think climate change will have a direct impact on their or their family’s finances. This constituency is still in play — and given sharply deteriorating macroeconomic conditions, soon-to-spike electricity prices, and the ever-increasing threat of climate disaster, these cost-of-living-focused voters could be far more vocal, relevant, and hungry for change than a coalition built on vague sabre-rattling against China.
In 2022, Democrats made a valiant first attempt to transform the state itself. Perhaps it was inadequate, perhaps it was impossible to do more at the time, but that’s no reason not to think seriously about the kind of policymaking, institutional, and financial interventions that would be called for should they get a second shot at realizing that goal. The rollback of the IRA only reveals how much Democrats left on the table three years ago ― and how much farther a real climate policy could go.
Renewables developers may yet be able to start construction before the One Big Beautiful Bill deadlines hit.
The Trump administration issued new rules for the wind and solar tax credits on Friday, closing the loop on a question that has been giving developers anxiety since the One Big Beautiful Bill Act passed in early July.
For decades, developers have been able to lock in tax credit eligibility by establishing that they have officially started construction on a project in one of two ways. They could complete “physical work of a significant nature,” such as excavating the project site or installing foundational equipment, or they could simply spend 5% of the total project budget, for instance by purchasing key components and putting them in a warehouse. After that, they had at least four years to start shipping power to the grid before stricter work requirements kicked in.
Shortly after signing the OBBBA, however, Trump issued an executive order directing the Treasury Department to revise its definition of the “beginning of construction” of a wind or solar project. Under the new law, this definition can make or break a project. OBBBA established new deadlines for wind and solar development, allowing projects that start construction before the end of this year to qualify for the tax credits as they currently stand. But projects that start construction between January 1 and July 4 of 2026 will have to follow stringent new rules limiting the use of materials with ties to China in order to qualify.
The start construction date also affects how long a developer has to complete a project and still qualify for credits. Projects that start before July 4 of next year have at least four years, while those that start after must meet an impossibly short timeline of being up and running in just a year and a half, by the end of 2027.
Some worried the new guidance would narrow that four year timeframe or affect project eligibility retroactively. Neither happened. The only major change the Treasury department made to the existing guidance was to get rid of the 5% safe harbor provision. While this is not nothing, and will certainly disqualify some projects that might otherwise have been able to claim the credits, it is nowhere near as calamitous for renewables as it could have been.
Projects can still establish they have started construction by completing “physical work of a significant nature,” and the definition of physical work still includes off-site work, such as the manufacturing of equipment. That means it’s still possible for a company to simply place an order for a custom piece of equipment, like a transformer, to establish their start date — as long as they have a binding contract in place and can demonstrate that the physical production of the equipment is underway.
The new guidance also contains a carve-out that allows solar projects that are less than 1.5 megawatts to use the 5% rule, which will help rooftop solar and smaller community-scale installations.
Trump’s executive order came after a reported deal he made with House Freedom Caucus Republicans who wanted to axe the tax credits altogether. The order directed the Treasury to prevent “the artificial acceleration or manipulation of eligibility” and restrict “the use of broad safe harbors unless a substantial portion of a subject facility has been built.”
Treasury’s relative restraint, then, comes as something of a relief. “It’s not good, it’s not helpful, but from my perspective, the guidance could have been a lot worse,” David Burton, a partner at Norton Rose Fulbright who specializes in energy tax credits, told me. “Utility-scale solar and wind developers should be able to plan around this and not be that harmed.”
That doesn’t mean clean energy groups are happy about the changes, though. “At a time when we need energy abundance, these rules create new federal red tape,” Heather O’Neill, president and CEO of the industry group Advanced Energy United, said in a statement. “These rules will make it more difficult and expensive to build and finance critical energy projects in the U.S.”
The changes don’t go into effect until September 2, so for the next two weeks, all projects can still utilize the 5% safe harbor.
Even though the rules are not the death-blow for projects that some anticipated, there’s still one big unknown that could squeeze development further: The Treasury department has yet to put out guidance related to the new foreign sourcing rules created by the OBBB. One of the big fears there is that companies will have to prove their lack of ties to China so far up their supply chains that compliance becomes impossible.
We probably won’t be left wondering for long, though. Trump’s executive order asked for those rules within 45 days, putting the due date on Monday.
On the worsening transformer shortage, China’s patent boom, and New York’s nuclear embrace
Current conditions: Tropical Storm Erin is still intensifying as it approaches the Caribbean • Rare August rainstorms are deluging the Pacific Northwest with a month’s worth of precipitation in 24 hours, threatening floods • Hong Kong has issued its highest-level “black” rainstorm warning multiple times this month as Tropical Storm Podul lashes southern China.
President Donald Trump’s order to keep large fossil-fueled power stations scheduled to retire between now and 2028 operating indefinitely will cost ratepayers across the United States $3.1 billion per year, according to new research from the consultancy Grid Strategies on behalf of four large environmental groups. If the Department of Energy expands the order to cover all 54 fossil fuel plants slated for closure in the next three years, the price tag for Americans whose rates fund the subsidies to keep the stations running would rise to $6 billion per year.
The problem may only grow. The agency’s existing mandates “perversely incentivize plant owners to claim they plan to retire so they can receive a ratepayer subsidy to remain open,” the report points out.
With electricity consumption hitting new records in the U.S., demand for transformers is surging. The years-long supply shortage for power and distribution transformers is now set to hit a deficit below demand of 30% and 10%, respectively, in 2025, according to a new report from the energy consultancy Wood Mackenzie. Complicating matters further for manufacturers scrambling to ramp up supply, Trump’s One Big Beautiful Bill Act is throwing clean-energy projects into jeopardy and sending mixed signals to factories on what kinds of transformers to produce. At the same time, tariffs are raising the price of materials needed to make more transformers.
“The U.S. transformer market stands at a critical juncture, with supply constraints threatening to undermine the nation's energy transition and grid reliability goals,” Ben Boucher, a senior supply chain analyst at Wood Mackenzie, said in a statement. “The convergence of accelerating electricity demand, aging infrastructure and supply chain vulnerabilities has created constraints that will persist well into the 2030s.”

For years, China was known for ripping off the West’s technology and patenting cheaper but more easily manufactured copies. Not anymore. China applied for twice as many high-quality clean energy patents as the U.S. in 2022, according to a New York Times analysis of the most recently available public data. The European Patent Office, which supplied data to the Times, defines a “high quality” patent as one that has been filed in two or more countries, indicating that the company or individual involved has a strong competitive interest in protecting its idea.
The growth in China’s intellectual property ambitions is a sign that Beijing’s strategic push to ramp up academic research and industrial innovation is maturing. “It is the opposite of an accident,” said Jenny Wong Leung, an analyst and data scientist at the Australian Strategic Policy Institute, which created a database of global research on technologies that are critical to nations’ economic and military security, including clean energy.
In June, New York Governor Kathy Hochul directed the New York Power Authority, the nation’s second-largest government-owned utility after the federal Tennessee Valley Authority, to support the construction of the state’s first new nuclear plant since the 1980s. Albany has plenty to sort out between now and the 15-year deadline for completing the project, including selecting a site, picking from one of the many new reactor designs, and finding a private partner. But one thing isn’t a problem, at least for now: Public support.
New Siena polling I covered in my Substack newsletter yesterday shows that 49% of registered voters in New York support the effort, with just 26% opposed. Both sides of the political spectrum are largely in lockstep, with Republican support outpacing that of Democrats by a margin of 55% to 49%. That’s lucky for Hochul, who will need support from the more politically conservative upper reaches of the state where the facility is likely to be built. For more on the technical and political considerations in play, here’s Heatmap’s Matthew Zeitlin on the plan.
It seems like everyone is abandoning their net zero goals. But not insurer Aviva. The company’s chief executive, Amanda Blanc, said the British giant remained committed to its carbon-cutting goals in the U.S. and the United Kingdom, The Guardian reported. With rising profits propelling shares in the company to their highest level since the 2008 financial crisis, Blanc said, “extreme weather conditions, climate change, and the impact that that has on our insurance business that actually insures properties” meant Aviva needed to “remain committed to our ambition.”
The red-headed wood pigeon once seemed on the verge of extinction. The population, endemic to Japan’s Ogasawara Islands, fell to below 80 individuals in the 2000s. But once its main predator, the feral cat, was removed, the bird made a remarkable comeback. A team of researchers at Kyoto University set out to find out why the expected problems from inbreeding never occurred. Per a press release: “Their results revealed that the frequency of highly deleterious mutations in the red-headed wood pigeon was lower than in the more widespread Japanese wood pigeon. This suggests that, rather than hindering it, the pigeon's success was likely rooted in its long-term persistence in a small population size prior to human impact.”
