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 led to a blackout for 100,000 people in and around New Orleans. 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.
Editor’s note: This story has been updated to clarify the relationship between the unplanned nuclear shutdown and the power outage in New Orleans.

Current conditions: More than two dozen locations across the Mountain West and Midwest broke temperature records Sunday as the nation’s heat wave roasted the Central United States • At least 12 people died fleeing a sweeping wildfire in Spain as hundreds of firefighters battled the flames • In Colorado, the ongoing Aspen Acres Fire has destroyed 780 structures.
During President Donald Trump’s first term, his administration’s big fight over public lands centered on the last two national monuments approved by Barack Obama on the way out of office. In 2017, Trump signed executive orders slashing the size of Bears Ears National Monument by 85% and nearby Grand Staircase-Escalante, both located in Utah, by half. Legal challenges were still pending when President Joe Biden restored the reserves to their initial size in 2021. But ABC4 in Utah reported last week that Trump planned to announce a new executive order to shrink the boundaries of the monuments yet again, likely this afternoon. “The Antiquities Act was a one-way statute when Teddy Roosevelt signed it into law. It was a one-way statute when President Trump tried to ignore it in 2017. It’s still a one-way statute today,” Aaron Weiss, the executive director of the Center for Western Priorities, said in a statement. “Just last month, Congress had a chance to weaken the management plan for Grand Staircase-Escalante and declined.”
In April, the Senate approved a House resolution using the Congressional Review Act to clear the way for a mining operation near Minnesota’s Boundary Waters, in what my colleague Jeva Lange called a declaration of “open season on public lands.”
Over the past 12 months ending in July, 56 fusion companies raised a total of $4.5 billion, a 69% jump over 2025’s total. That’s according to the latest data from the Fusion Industry Association’s annual report. Total funding since 2021 now stands at $14.2 billion, a sevenfold increase. Twice as many companies are now competing as when the report was first published six years ago. This year’s figures include major financing rounds from Commonwealth Fusion Systems, which raised $863 million last August; Inertia Enterprises, which brought in $450 million in February; Helion Energy, which raked in $456 million last month; and the European champion Proxima Energy, which netted $518 million this month.

Back in January, I told you when the price of copper hit a record high. We kept track, too, of Chilean miners’ plans to ramp up production last month. But Chile’s output of copper fell sharply in May, according to a Mining.com analysis of data from Codelco, the country’s national miner. Production from major miners such as BHP dropped over 18% year-on-year to 106,300 metric tons. The fall comes as key mines in the South American nation face declining ore quality.
The move comes right as one of China’s biggest solar manufacturers switched from using silver to copper in its panels in response to what Bloomberg described as the surging prices of the precious metal.

The world’s first commercial satellite powered by nuclear energy has launched into space after escaping the Earth’s atmosphere on a SpaceX Transporter-17 vessel. Miami-based City Labs, the company behind the launch, specializes in designing, developing, and manufacturing micro power technology based on the radioisotope tritium. The technology is meant to provide long-lasting, maintenance-free power for medical, industrial and space applications. “This is a historic step for commercial nuclear power in space,” City Labs CEO Peter Cabauy told World Nuclear News. The system “demonstrates that safe, compact, and regulatory-approved nuclear power systems are ready for routine commercial deployment.” The technology “enables persistent, always-on” operations “that are not constrained by sunlight or battery life.”
New York is behind on its development of clean energy. Its offshore wind buildout has stagnated. The state has limited space and sunlight for large-scale solar. And while Albany is positioning itself as the state leader on nuclear power with plans to construct more reactors upstate, those efforts are long term, and only just began. But one source of green power is expanding faster than expected: rooftop solar. New Yorkers installed 8 gigawatts of distributed solar capacity, putting the state ahead of schedule moving toward its legally-binding goal of 10 gigawatts by 2030. “New York continues to set the bar high as we mark another milestone for solar within our communities across the state,” New York Governor Kathy Hochul, a Democrat, said in a statement. “This is low-cost, reliable clean energy that is delivering cost savings for families and businesses while expanding the availability of renewable energy which benefits our environment, our economy and contributes to New York’s diverse energy resource mix.” That’s optimistic. But as Heatmap’s contributor Jesse Jenkins explained on our Shift Key podcast in 2023, there are limits to how big an impact rooftop solar can have on emissions.
China, as I told you last week, has been investing heavily in green hydrogen. The statement in Beijing’s latest Five-Year Plan confirms that green hydrogen, ammonia, and methanol “will play a significant role in decarbonizing China,” Hydrogen Insight reported.
Building a data center is also quite carbon-intensive.
When I helped start Heatmap News three years ago, I didn’t think I would be writing this much about big tech companies.
I knew that, sure, they were crucial to America’s ability to develop and scale some next-generation emissions-reducing technologies. (By then, Microsoft had already started its huge carbon removal purchasing program.) And, yes, I knew they bought a lot of renewables. But I still understood their clean energy programs chiefly as an employee perk — a way for some of the economy’s richest firms to show their largely urban, college-educated, and liberal employees that they cared.
Perhaps that was true once. It’s not true anymore. Over the past several years, the tech companies have become major electricity consumers and producers in their own right. Artificial intelligence has turned their electricity procurement and development businesses into core operational competencies. (Meta and Microsoft have even considered entering the electricity trading business.) Some of the thorniest questions in climate policy were first encountered by these tech companies.
More importantly, their hunger for electricity has transformed them into quasi-industrial companies — and given them enough heft in the market to sometimes counterbalance (and sometimes collaborate with) the utilities and fossil fuel firms that previously steered the sector. As such, they’re now crucial parts of the U.S. decarbonization story.
Three companies in particular dominate the artificial intelligence cloud business: Google, Amazon, and Microsoft.
The country’s best-known frontier labs, such as OpenAI and Anthropic, rely on these companies to provide their compute power; Amazon Web Services is the backbone of virtually the entire online software industry. Amazon, Google, and Microsoft account for more than half of the country’s data center power capacity, according to the investment firm Jeffries.
So these companies’ emissions are, in a sense, not only their own; they also give us a view into the AI industry’s carbon footprint more broadly.
Over the past two weeks, all three of these cloud providers released their energy and emissions data for the past year, and we’ve looked at the top line findings from these reports in past editions. Today I want to briefly dive into what they could mean together.
Let’s handle the part you already know: Everyone’s emissions are up.
Microsoft’s emissions grew by 25% last year, their largest year-over-year leap since the pandemic. Amazon’s emissions leapt by 16%, its largest one-year increase ever. Google’s emissions increased by 18%, rising above their pre-pandemic level.
This surge will make the companies’ climate goals increasingly difficult to meet — and some of them are coming up fast. Microsoft has pledged to become ‘carbon negative’ by 2030, meaning it must remove more climate pollution from the atmosphere than it emits in that year. Google has pledged to achieve net zero by 2030, a goal that requires — by its own estimate — cutting its emissions in half by that year, as compared to their 2019 level. Amazon, meanwhile, has pledged to achieve net-zero in its operations by 2040.
All three firms’ greenhouse gas emissions are up because of the AI data center boom. Microsoft consumes nearly four times as much electricity as it did before the pandemic; Google’s electricity use has more than doubled.
These companies’ energy use has swelled, too, but at least as of last year, nearly all of their energy demand still took the form of electricity. When we think about “electrification” in the national context, perhaps we should think at least as much about these AI megalodons as we do about heat pump or battery manufacturers.
Amazon, to its shame, does not publish recent electricity usage data, so it doesn’t appear on either of these charts.
But outsiders have estimated its power consumption based on the numbers it does publish. Hendrik Rood, an IT researcher and consultant in the Netherlands, calculates that Amazon’s data center business used 78,000 gigawatt-hours in 2025. That would mean it consumes nearly as much electricity as Microsoft and Google combined.
As I cautioned yesterday, some of these figures are already outdated. Although all three companies just released their 2025 sustainability data, Microsoft brackets its report to the fiscal year, which ended on June 30, 2025. Google and Amazon’s data covers the calendar year.
In what might be a quirk inherent to the genre, all three sustainability reports have a somewhat defensive tone (or at least a writing style that tries to anticipate quibbles). These companies know that their sustainability pledges, embraced in the heady flush of 2020 and 2021, have become much more difficult to fulfill in the AI era. And they want you to know that all of their emissions could be worse — if not for their corporate policies, pollution might be much higher.
I can’t say I find these counterfactuals entirely believable. We don’t know what Google or Microsoft or Amazon would do if, say, computing were more energy intensive or a certain process more environmentally damaging. And Jevon’s paradox suggests that every gain in efficiency — especially for a service as in-demand as AI — will make it cheaper to use AI, therefore raising its energy demand.
But I do think it’s worth sharing these claims to get some perspective. Google, for its part, says that its corporate emissions would be five times higher than they are if not for its total slate of policies:

Microsoft takes a more clinical approach. It selects four of its corporate policies: “carbon-free electricity, sustainable fuels, XBOX console efficiency,” as well as efforts to decarbonize its Surface tablet production. If not for these interventions, it says, it would have emitted 34 million tons of greenhouse gas into the atmosphere last year, not the 21 million tons that it did produce.
For all the focus on the difficulty of powering data centers (including by Heatmap), electricity does not drive most of these companies’ emissions — or it didn’t in the first half of last year, at least. The majority of Microsoft, Google, and Amazon’s greenhouse gas emissions came from what are dubbed “scope 3” emissions, a somewhat nebulous category that includes buildings, employee travel, and the full carbon footprint of their supply chain. This category reflects the AI boom in its own way.
(Skip this if you’re a sustainability nerd: In the classic schema used for corporate emissions accounting, “scope 1” emissions are direct fossil fuel pollution from an asset that the company owns or controls, “scope 2” emissions are pollution associated with the electricity, steam, or chilled water purchased by the company, and “scope 3” emissions are everything else — pollution from the company’s upstream supply chain and its downstream product use. I find this scheme makes somewhat more sense for businesses like airlines and automakers than it does for technology conglomerates. But that’s a different newsletter.)
It makes sense, then, that Amazon should have huge scope 3 emissions. The scope 3 subcategory called “Purchased Goods and Services” drives the largest share of its emissions; these include pollution from goods and services that Amazon buys for its employees to use, as well as all the embodied carbon in its line of Amazon Basics products.
But the biggest driver of scope 3 emissions — and thus for emissions overall — for Microsoft and Google came from “capital goods,” a category that covers new construction, physical assets and other fixed infrastructure used to produce products and services. More than 40% of Microsoft’s total emissions came from capital goods, and they made up more than 9 million metric tons of the company’s greenhouse gases. Google doesn’t fully aggregate out its “capital goods” category, combining it with the “use of sold products” subcategory, but it was responsible for almost 9 million tons as well.
These capital goods include the new data centers themselves: all the cement, steel, server racks, and silicon that actually make up the physical infrastructure supporting the AI boom. Here at Heatmap, we often focus on the electricity sector because it’s where so much change. But it’s good to remember that construction remains enormously carbon-intensive, and the literal buildings that house AI are, in many cases, still driving a disproportionate amount of emissions.
The July 4 heat wave showed just how far the metropolis has to go to reach its decarbonization goals.
New York City’s decarbonization plan has stalled. The events of this year’s Fourth of July weekend all but prove it.
The temperature in the city reached as high as 100 degrees Fahrenheit on Thursday, July 2, the hottest it’s been here in 14 years. As New Yorkers blasted their air conditioners to stay cool, utilities drew on all of New York’s resources to serve the resulting electricity demand for cooling. These included a fleet of dual-fuel power plants, which can burn both oil and natural gas and encompasses many of its peakers, which turn on to deal with spikes of demand.
Those dual-fuel plants pushed over 10 gigawatts of electricity onto the grid on the evening of July 1— about a third of the total load in the state — and hit similar peaks on the 2nd and 3rd. The peaker fleet owned and operated by the New York Power Authority was operational for over two-thirds of the heat wave, which persisted for four consecutive days, while some ran nonstop from 7 a.m. July 2 to 3 a.m. July 4, according to NYPA.
In response to questions about the use of its peakers during the heat wave, a NYPA spokesperson told me, “During times of peak energy demand, like last week’s heat wave, the state’s independent grid operator called upon NYPA’s Small Natural Gas Power Plants to run well beyond their typical usage to meet high energy needs and prevent localized blackouts.”
While specific generator information is a protected trade secret, they said, “capacity suppliers are critical resources to meet system peak loads like those experienced during the recent heatwave.”
And yet still, over 100,000 people lost power during the heat wave. Real-time electricity prices in the area of the New York grid that includes the city got as high as $1,465 per megawatt-hour on the evening of July 3, according to data collected by Grid Status.
At the same time, the latest addition to New York’s non-carbon electricity generation fleet, a transmission line from Quebec that can transmit up to 1,250 megawatts known as the Champlain Hudson Power Express, was struggling. It experienced an unplanned outage on July 1, the first day of the heat wave, followed by a second outage beginning on July 4 that still had not been resolved as of Friday.
Since 2014, the city has had an aspirational goal of reducing emissions by 80% of its 2005 levels by 2050. CHPE was a major part of that plan, which also included offshore wind and utility-scale solar. There has been progress: Of the 1,000 megawatts of solar the city aims to have installed by 2030, about two thirds have been built. Even so, about 90% of New York City’s electricity came from fossil fuels in 2025, according to the city’s comptroller.
Why the difficulty decarbonizing? Blame a mixture of policy and geography. New York City is dense and has a lot of old buildings with old heating systems. Reducing consumption of fossil fuels requires getting cars off the road (congestion pricing) and retrofitting buildings with electric appliances (Local Law 97).
But that’s the demand side — the supply side is far trickier. Utility-scale non-carbon-emitting power on the orders of hundreds of megawatts or a gigawatt will have to be built elsewhere and piped in via transmission lines. That means offshore wind, solar (ideally with battery storage), and maybe one day nuclear power.
To the extent New York City can build solar and storage locally, it means dealing with a thicket of building regulations and local opposition. Efforts to shut down or replace peaker plants in the city have run into a brick wall at the New York Independent System Operator, which has declared that at least some peakers will have to stay online through the end of the decade to maintain system-wide reliability.
The only other new source of carbon-free power currently under construction is the offshore wind project Empire Wind, due to come online in 2027. NYISO said last year that without CHPE, Empire, and two local transmission projects planned to enter service by 2030, New York City would be “deficient in the summer” through 2030.
Of course developers have scrapped several other offshore wind projects over the years, whether due to problems procuring the right size turbine or the Trump administration buying out their lease. And though New York Governor Kathy Hochul pledged last summer to develop at least a gigawatt of new nuclear capacity in the northern region of the state, that is probably a decade away from fruition.
Meanwhile the Clean Path transmission line, which was meant to connect New York City to several gigawatts of new wind, solar and hydropower, saw its contracts canceled in late 2024 as its projected costs continued to rise. Last year, utility regulators shut down an effort by the state-run New York Power Authority to take it over as a “priority transmission project,” questioning whether it was “needed expeditiously” to meet downstate reliability needs and arguing that the project “will not be needed to serve substantial amounts of generation until well after 2033, and possibly not until 2040.”
While the city has some utility-scale battery storage systems, would-be developers have faced intense local opposition. Fullmark Energy, for instance, scrapped a planned 650-megawatt storage project after protests from political figures, including frequent mayoral candidate Curtis Sliwa. A dispute over another battery storage project in Queens has escalated into accusations of assault leveled by Councilmember Phil Wong, who called for a criminal investigation into what he said was an assault by a contractor for a project against his staffer.
So what’s left for New York City to do?
Any near-term progress will likely come from increasing efficiency and adding marginal generation capacity, as opposed to large-scale new projects and decommissioning of power plants.
“We need to max out our energy efficiency gains from Local Law 97,” former New York City Chief Climate Policy Advisor Daniel Zarelli told me, referring to a 2019 law mandating steep reductions in emissions from large buildings in the city, which came into effect two years ago. He also called for a further“push on batteries and behind the meter solar, clean energy, and energy efficiency.”
Already across the state, behind-the-meter solar is shaving off peak power demand. On the afternoon of July 2, behind-the-meter solar accounted served about 4.5 gigawatts to users, according to NYISO and Grid Status data.
Going forward, Zarelli said, the city should use its purchasing and planning power — as it did with CHPE — for projects like resurrecting Clean Path. “We need to be starting now. Maybe it’s not by 2030, but soon after we could be getting the benefit of that.”
“Battery developers started to see interconnection costs that were around 30 or 40 times what is standard,” Patrick Robbins, director of the Utility Customers Association told me. “It just means that new battery projects completely don’t pencil out and so we have a de facto moratorium on new [battery] projects.”
Advocates for solar and storage have blamed Con Edison for the city’s slow progress there, claiming that changes in the interconnection process have made it essentially cost prohibitive for battery storage developers to move forward on new projects.
Some of these fights have landed in front of New York’s Public Service Commission. In a filing, the city cited data from Con Edison showing that “the interconnection costs for some projects … have increased by thousands of percent,” citing one project whose interconnection costs jumped from $640,000 to over $35 million due to changes in how Con Edison attributed grid costs from new projects.
"Battery storage is essential to New York's clean energy future, and Con Edison strongly supports the development of energy storage when projects are deployed at the right locations, at the appropriate scale, and with operating parameters that provide the greatest benefit to customers and the electric grid,” a Con Edison spokesperson told me. “Because grid constraints vary across our system — from neighborhood‑level distribution lines to major transmission corridors — the location of a battery ultimately determines how much benefit it can deliver to the grid and to customers.”
There were 115 megawatts of battery storage operational in New York City at the end of last year, according to Con Edison, and 865 megawatts of projects with interconnection agreements. Peak load in the region is about 10,000 megawatts, meaning that these new projects would meaningfully alter the way the utility serves its customers.
Con Edison has claimed in a regulatory filing that the concentration of projects could lead to “significant impacts from BESS charging on infrastructure upstream of primary feeders,” necessitating the changes to its interconnection process. The city claimed in its filing that the added cost has “understandably chilled ongoing development activity at a time when New York City needs more supply resources capable of serving peak demand.”
When I reached out to the Mayor’s Office of Climate & Environmental Justice about the dispute, I received a statement in return from New York City Chief Climate Officer Louise Yeung: “Expanding battery storage capacity will be critical to New York City’s clean energy future, as extreme climate events continue to strain our grid system,” she said. “The City is working across agencies and communities to ensure battery energy storage projects are deployed safely and can provide reliable power when New Yorkers need it most.”
As for residential solar and storage, it will likely take years for those distributed resources to become a regular part of New York City’s energy landscape. There’s only one fully permitted and approved residential storage system allowed in New York City, which was installed earlier this year by Brooklyn Solar Works. Negotiating approvals with city agencies including the Department of Buildings and the New York City Fire Department took around six years, the company’s vice president of sales, Steve Nelson, told me.
“It’s New York City. We’re expecting there to be some level of bureaucracy and some lift to get that stuff approved,” Nelson said. “But what we also lack is a ready, readily accessible residential battery that meets the criteria that these departments have set.”
All that adds up to both a practical and a political gap for decarbonization, Zarelli told me.
“Batteries are a great way to connect the climate agenda and the affordability agenda, and it’s in the mayor’s control — it’s the regulatory apparatus at FDNY,” he said. “That’s a big near-term play that I think would make a big difference.”
Earlier this year, New York City Councilmember James Gennaro introduced a bill to amend the fire code to relax some battery storage permitting and safety requirements. But that still leaves the city’s decarbonization advocates with many big fish to fry.
“It’s a challenging future that’s still out in front of us, and how to navigate that is really difficult. But it’d be good if we were actually aligned on what our goals were as a society,” Zarelli said.
