Investors are betting on gas to meet the U.S.’s growing electricity demand. Turbine manufacturers, however, have other plans.

Thanks to skyrocketing investment in data centers, manufacturing, and electrification, American electricity demand is now expected to grow nearly 16% over the next four years, a striking departure from two decades of tepid load growth. Providing the energy required to meet this new demand may require a six-fold increase in the pace of building new generation and new transmission ― hence bipartisan calls for an energy “abundance” agenda and, where the Trump administration is concerned, dreams of “energy dominance.” This is the next frontier in the fight between clean energy and fossil energy. Which one will end up fueling all of this new demand?
Investors are betting on natural gas. If these demand projections aren’t just hot air, the energy resource fueling all this growth will be, so to speak. Where actually deploying new gas power is concerned, however, there’s a big problem: All major gas turbine manufacturers, slammed by massive order growth, now have backlogs for new turbine deliveries stretching out to 2029 or later. Energy news coverage has mentioned these potential project development delays sometimes in passing, sometimes not at all. But this looming mismatch between gas power demand and turbine supply is a real problem for the grid and everyone who depends on it.
Taking a closer look at the investment plans of GE Vernova, the U.S.’s leading gas turbine manufacturer, suggests that, even as energy demand ramps up, these delays will persist. Rather than potentially overinvest in the face of rising demand and suffer the consequence of falling prices, GE Vernova and its competitors are committed to capital discipline, lengthening their order book, and defending shareholder value. Their reluctance to invest, while justified in some part by the nature and history of the industry, will threaten policymakers’ push for energy abundance ― to say nothing about economic growth or innovation.
Meanwhile, supply chain shortages will constrain the growth of clean energy generation. Inadequate investment in gas and an insufficient buildout of renewables in the face of unprecedented demand growth ― these are a toxic cocktail for the American energy system. Forget visions of an all-of-the-above energy strategy. How about none of the above?
Energy project developers, utilities, and investors have already started adjusting their gas buildout expectations and timelines. NextEra CEO John Ketchum stated in an earnings call that new gas projects “won’t be available at scale until 2030, and then only in certain pockets of the U.S.” That’s due not only to turbine queues, but also to an historically sluggish and increasingly expensive gas project development environment. “The country is starting from a standing start,” he added. “This is an industry that really hasn’t seen any active development or construction in years … all of that puts pressure on cost.”
Even in Texas, where lawmakers created the Texas Energy Fund to provide $10 billion of concessional financing to new gas power plants, delays are biting developers’ balance sheets. Just last week, private developer Engie withdrew two loan applications for gas peaker plant projects due to “equipment procurement constraints.” There’s no other way to spin it — the turbines are the problem.
Given that wait times and reservation payments drain developers’ liquidity and increase their financing costs, energy giants are trying to cut the line. Chevron is partnering with GE Vernova to develop up to 4 gigawatts of gas power plants for data centers. NextEra also announced a partnership with GE Vernova, through which the two companies will co-develop and co-own “multiple gigawatts” of natural gas power plants.
It’s safe to say that GE Vernova’s power division is riding high. The company’s investor materials suggest a heady growth trajectory. Gas turbine equipment orders rose 66% between 2023 and 2024, from 41 turbines to 68 turbines. Those 68 turbines represented about 20 gigawatts of capacity, double 2023’s order book. Developers reserved 9 gigawatts more of turbines; those reservations will turn into contracted production orders by 2026. At this point, 90% of GE Vernova’s total order volumes are in its backlog; for its power division, that represents almost $74 billion of equipment delivery and service contracts.
The company plans to invest $300 million into its gas power business in the next two years. And CEO Scott Strazik is pitching investors on continued growth. “Given our expansion plans to produce 70 to 80 heavy-duty gas turbines per year beginning in the second half of 2026, up from 48 this year, we are positioning to meet this demand. We expect to grow our gas equipment backlog considerably in 2025, even as we ramp to ship approximately 20 gigawatts annually starting in 2027, and expect to remain at that level going forward,” he said on the company’s Q4 earnings call.
That last sentence should give readers pause: GE Vernova has plans to build no more than 20 gigawatts of turbines per year, and developers that miss the cutoffs will just have to queue up for the next year’s order book. Why the limit?
Strazik laid out two key reasons. First, he’s looking for developers’ “receptivity to pay for what I will call premium slots” in 2028 and 2029, to “capture every dollar of price with the precious slots available,” as he told investors during a different presentation in December. GE Vernova’s annual report, which it released in February, refers to this strategy ― inviting desperate developers to bid up the price of scarce turbines ― as “expanding margins in backlog.” Second, the company remains hampered by supply constraints, particularly on ramping up its new heavy-duty and H-class turbines. There are real limits to how much more GE Vernova can build, and how quickly.
But over the longer term, it looks like GE Vernova is intentionally committing more to capital discipline rather than to broader capacity expansion. The company has $1.7 billion in free cash flow, a third of which it will return to shareholders through dividends and stock buybacks. And Strazik wants to avoid using the rest to underwrite what he sees as dangerous overcapacity that could threaten GE Vernova’s profitability. “I think we have to be very thoughtful to make sure that we don't add too much capacity, even though we are starting to sell slots into 2029,” he said during the investor update. “We're going to continue to be very sequential on how we invest.”
Strazik’s current strategy prioritizes productivity and efficiency improvements at GE Vernova’s existing plant in South Carolina over building new manufacturing facilities. Some capacity expansion, sure ― but no new plant. “Concrete's expensive, cranes are difficult,” he told investors. The company’s main competitors abroad, Mitsubishi and Siemens, have the same backlogs, and Mitsubishi, at least, is responding with a similarly measured strategy. Mitsubishi CFO Hisato Kozawa is open to some degree of capacity expansion, but maintains that Mitsubishi can only increase capacity “in a very planned manner with discipline. And if we need more capacity, we may want to first improve the rotation of the capacity.”
To the CEOs of all three companies, history would likely seem to justify this discipline. In 2017 and 2018, years of investment into capacity expansion coincided with a near-total collapse in global demand for gas turbines. This market crash was most likely the combined effect of low energy demand growth, energy efficiency improvements, continued use of coal power across Asia, the growing share of renewable energy on the grid, and investors’ realization that solar and wind energy could meaningfully undercut gas on price. All three companies laid off tens of thousands of employees, and the crash contributed to the complete breakup of General Electric and its partial spin-off into GE Vernova last year.
These gas turbine manufacturers are also some of the world’s leading wind turbine blade manufacturers, and a similar fate befell that sector in the past decade. Large-scale capacity expansion and competition for contracts drove down costs and margins across the supply chain — only for those to move sharply in reverse when supply chains froze up during the pandemic and interest rates shot up in 2023. Now offshore wind projects are plagued with problems and, at least in the U.S., President Trump’s de facto moratorium on offshore wind development has further reduced the sector’s ability to bounce back. These companies have been burned before. It only makes sense not to repeat past mistakes.
Combined-cycle gas turbines are complex machines, similar to airline engines in their intricacy and in the extensive global supply chains required to produce them. But their leading producers, afraid of getting over their skis, won’t undertake the massive upfront investments required to increase their long-term production capacity. Where does this leave the energy transition?
Bankers and energy project developers alike can see the writing on the wall. Beth Waters, managing director for project finance at Japanese bank MUFG, has insisted that “renewables have to be part of the electricity mix. It cannot just be gas-fired.” NextEra’s Ketchum has said the same: “Renewables are here today,” he stated during the latest earnings call — unlike gas. Jigar Shah, the head of the Department of Energy’s Loan Programs Office under President Biden, wrote on LinkedIn about his confidence that “batteries will be deployed at 10X the capacity of combined cycle natural gas units over the next 4 years.” Major utility companies, for their part, still have large clean energy procurement targets in their integrated resource plans. The smart money is clearly betting that an “all-of-the-above” energy deployment strategy will be better than eschewing any particular energy source.
They’re being optimistic. Not only does new utility-scale renewable energy take years to build, there’s also not yet enough transmission and longer-term energy storage on the grid to balance the variance in existing solar and wind resources. That prevents solar and wind from providing the kind of 24-hour stable power that corporate and industrial customers demand. Expanding energy storage and transmission resources will depend not just on regulatory reforms to permitting and interconnection, but also on resolving the severe bottleneck in grid transformers, where analysts believe capacity expansion has also failed to meet roaring demand, resulting in wait times of three to four years. (GE Vernova and Siemens build grid transformers too.) The status quo has left hundreds of gigawatts of clean energy projects across the country stuck in a regulatory and financing limbo, and the grid issues that tie up clean energy development will further constrain gas power growth.
To be sure, President Trump’s “energy dominance” agenda seems to favor the development of clean firm energy resources, such as nuclear and enhanced geothermal, to cut through the literal gridlock. The gas turbine manufacturers, all of which build steam turbines for nuclear power, stand to benefit from interest in restarting and upgrading now-shuttered plants. But building new nuclear projects currently takes at least 10 years, if not more. The singular new nuclear project built in the U.S. in the past three decades was completed seven years late and almost $20 billion over budget.
Enhanced geothermal might fare somewhat better ― its drilling technology comes straight from the fracking sector, and the pilot projects of companies like Fervo are achieving impressive heat and electricity production targets. Still, to turn heat into electricity, Fervo needs turbines, too. While enhanced geothermal projects need organic Rankine cycle turbines, as opposed to the combined-cycle gas turbines used in gas power plants, commodity market strategist Alex Turnbull theorizes that the commonalities between the two will threaten geothermal developers with the same delays and bottlenecks. (Fervo’s turbine supplier is an Italian subsidiary of Mitsubishi.)
The tech giants building data centers are already investing in new power ― but if neither nuclear nor geothermal can be deployed at scale in the absence of massive policy support, then that leaves tech companies paying for whatever energy sources their regional electricity grid relies on in the meantime. As Cy McGeady, a fellow at the Center for Strategic and International Studies, told Heatmap last year, “Nobody is willing to not build the next data center because of inability to access renewables.” But drawing so much from existing resources ― mostly gas, but also nuclear ― without building sufficient new power leaves less for every other energy consumer.
Policymakers on both sides of the aisle have their work cut out for them to avoid a crisis born of a failure to build any energy resource adequately: They must execute a thorough grid overhaul while also punching through the specific supply chain bottlenecks that prevent energy generation from being built quickly. Regardless of energy demand projections, these are goals worth pursuing. They advance grid reliability, energy affordability, and decarbonization, as well as accommodate any necessary energy supply growth.
Still, it’s worth questioning the prevailing narratives around load growth. It’s not clear how much energy data centers in particular will actually require. Not only have innovations like DeepSeek challenged market assumptions about tech companies’ investment requirements, but recent research also suggests that load growth projections could fall significantly if data centers’ energy demand were more flexible. Not to mention that data center developers often make duplicate interconnection requests with different utilities to maximize their chance of securing a power agreement.
Our energy grid will need a lot less hot air if data center demand goes up in smoke ― and that would be a relief for American consumers and the climate alike. But courting a gas turbine crisis should itself give policymakers pause. The fact that our energy system is at a point where neither turbines nor transformers nor transmission is available in sufficient capacity to meet any policymaker’s vision of energy abundance suggests that our leaders must reorient the government’s relationship to industry. During periods of economic uncertainty, capital discipline might appear rational, even profitable. But the power sector’s profits are, through rising energy bills and more frequent climate disasters, revealed to be everyone else’s costs. Between clean energy and fossil fuels — between what Americans need and what private industry can provide — the energy transition is shaping up to be, quite literally, a power struggle.

On Massachusetts’ offshore headwinds, Biden’s gas rules, and Australia’s free power
Current conditions: The Pacific Northwest is getting blasted with winds of up to 70 miles per hour • Heavy snow is coming this week for the higher elevations in New England and upstate New York • San Cristóbal de La Laguna in the Canary Islands saw temperatures surge to 95 degrees Fahrenheit.

Democratic candidates swept to victory in key races with implications for climate change on Tuesday night. In Virginia, Democrat Abigail Spanberger — who vowed to push forward with offshore wind, new nuclear reactors, and fusion energy — seized the governor’s mansion in the first major race to be called after polls closed. In New Jersey, Democrat Mikie Sherrill, who campaigned on building new nuclear plants and pressing the state’s grid operator, PJM Interconnection, to cut electricity prices, trounced her Republican opponent. In New York City, Democrat Zohran Mamdani, who said little about energy during his campaign but came out in the last debate in favor of nuclear power, easily beat back his two rivals for Gracie Mansion. Yet the Georgia Public Service Commission's incumbent Republican Tim Echols lost his race against Democrat Alicia Johnson, a defeat for a conservative who championed construction of the only two nuclear reactors built from scratch in modern U.S. history. In what one expert called a sign of a “seismic shift” on the commission, Peter Hubbard, another Democrat running to flip a seat on the commission, also won.
At a moment when the Trump administration is “disassembling climate policy across the federal government,” Heatmap’s Emily Pontecorvo wrote, “state elections are arguably more important to climate action than ever.”
A federal judge in Washington ruled Tuesday that the Trump administration can reconsider the Biden-era approval of SouthCoast Wind off the coast of Nantucket, Massachusetts. The decision, reported in The New York Times, is a setback for the joint venture between EDP Renewables and Engie, and handed the White House a victory in what we’ve called here the administration’s “total war on wind.” Judge Tanya S. Chutkan of the U.S. District Court for the District of Columbia ruled that the project developers would not “suffer immediate and significant hardship” if the Department of the Interior’s Bureau of Ocean Energy Management were allowed to reevaluate the project’s construction and operation permits.

Meanwhile, the U.S. Court of Appeals for the D.C. Circuit upheld Biden-era Department of Energy efficiency rules for gas-fired residential furnaces and commercial water heaters in a ruling that rejected the gas industry’s challenge on Tuesday. “Overall, we find that DOE’s economic justification analysis and conclusions were robust,” the panel ruled, according to Bloomberg Law. The decision will maintain the status quo of how the agency enforces energy efficiency rules for the appliances. Under standards updated in 2021 and 2023, the Biden-era bureaucrats proposed raising efficiency levels to 95% for furnaces and using condensing model designs to heat water.
White House budget officials pressed the Environmental Protection Agency to expand its rollback of tailpipe regulations this summer as the agency sought to repeal the foundational policy that undergirds federal climate rules, E&E News reported. Documents the green newswire service obtained showed the White House Office of Management and Budget pushed the environmental regulator to weaken limits on vehicular pollution, including soot and smog-forming compounds in addition to planet-heating carbon. The EPA initially pushed back, but the documents revealed the staffers at OMB demanded the agency pursue a more aggressive rollback.
Australia launched a new plan to force energy companies to offer free electricity to households during the day to use excess solar power and push the grid away from coal and gas. The policy, called the “Solar Sharer” plan, aims to take advantage of the country’s vast rooftop solar panels. More than 4 million of Australia’s 10.9 million households have panels, and the capacity has overtaken the nation’s remaining coal-fired power stations. The proposal, the Financial Times reported, would also extend the benefits of distributed solar resources to the country’s renters and apartment dwellers.
For years, nuclear scientists have dreamed of harnessing atomic energy from thorium, potentially shrinking radioactive waste and reducing the risk of weapons proliferation compared to uranium. In the West, that has remained largely a dream. In China, however, researchers are vaulting ahead. This week, Chinese scientists announced a major breakthrough in converting thorium to uranium in a reactor. “This marks the first time international experimental data has been obtained after thorium was introduced into a molten salt reactor, making it the only operational molten salt reactor in the world to have successfully incorporated thorium fuel,” Shanghai Institute of Applied Physics of the Chinese Academy of Sciences said in a statement.
Rob and Jesse touch base with WeaveGrid CEO Apoorv Bhargava.
Data centers aren’t the only driver of rising power use. The inexorable shift to electric vehicles — which has been slowed, but not stopped, by Donald Trump’s policies — is also pushing up electricity use across the country. That puts a strain on the grid — but EVs could also be a strength.
On this week’s episode of Shift Key, Rob and Jesse talk to Apoorv Bhargava, the CEO and cofounder of WeaveGrid, a startup that helps people charge their vehicles in a way that’s better and cleaner for the grid. They chat about why EV charging remains way too complicated, why it should be more like paying a cellphone bill than filling up at a gas station, and how the AI boom has already changed the utility sector.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University.

Here is an excerpt from our conversation:
Robinson Meyer: In your experience, are consumers willing to make this deal, where they get some money off on their power bill in order to change how their car works? Because it does seem to include a mindset change for people, where they’re going from thinking of their car as a machine — I mean, this is part of the broader transition to EVs. But there’s an even further mindset shift that seems to me like it would be required here, where you go from thinking about your car as a machine that you wholly own — that enables your freedom, that is ready to drive a certain amount of miles at any time — to a machine that enables you to have transportation services but also is one instantiation of the great big cloud of services and digital technologies and commodity energy products that surround us at any time.
Apoorv Bhargava: Yeah, I mean, look, I think we have seen faster adoption rates than any other consumer-side resource participating in energy has. So I feel very good about that. But ultimately, I think of this as a transition to the normal experience for folks who are going through what is a new experience altogether.
Again, similar to my cell phone plan, if this was just offered to me as a standard offering — you buy an EV, your utility offers you a plan, it’s called the EV plan — in the same way that we have EV time-of-use rates, quote-unquote. If you’re just offered an EV plan where it’s exactly the same thing — I’m going to make sure you’re fully charged every night in the way you want it to be charged, with the cleanest, cheapest, most reliable charging possible, and it’s just being taken care of.
I think what’s so hard for most folks to grok, is that the way this experience works is it’s supposed to be completely frictionless, right? You’re really supposed to not think about it. It’s actually only in the few moments where you need to change your 99% behavior to the 1% behavior — where you’re like, Oh, I need to go to the airport, or, Oh, I need to go on a road trip. That’s where you need to think about it. It’s flipped from thermostat management programs where you actually need to think about it actively in the moments where the grid is really strained.
Where we’ve overinvested, in my view —and this is a controversial view — we’ve overinvested in trying to make EVs be like gas stations or like the gas station model. We keep talking about it all the time. We’ve over-talked about range anxiety. The fact of the matter is 80% of charging still happens at home. Even in the long run, 30% of charging will happen in the workplace. 50- plus-percent will happen at home. It’s very little charging that’s gonna happen on fast charging. But we’ve talked so much, ad nauseam, about fast charging that we’ve actually forgotten that underpinning the iceberg of the electrification cost is the grid itself. And never before has the grid been so strained.

The self-described “ecosocialist” ran an ultra-disciplined campaign for New York City mayor. Once he’s in office, the climate issue could become unavoidable.
Zohran Mamdani, the New York state assemblyman, democratic socialist, and Democratic nominee, was elected mayor of New York City on Tuesday night.
Many factors fueled his longshot rise to Gracie Mansion — a congested primary field, a gleam-in-his-eyes approach to new media, and an optimistic left-wing worldview rendered newly credible by global tumult — but perhaps above all was a nonstop, months-long performance of bravura message discipline. Since the Democratic primary began in earnest earlier this year, Mamdani has harped in virtually every public appearance on what he has described as New York’s “affordability crisis,” promising to lower the city’s cost of living for working-class residents.
He hammered that message even as the election required him to play a shifting set of roles. During the primary, he set himself apart from a field overflowing with progressives by showcasing his differences with the Democratic Party. During the general election, he became the consummate Democrat, earning the votes of the party’s most loyal voters even as the former governor and one-time old-guard Democrat Andrew Cuomo ran an independent bid. Fittingly, Mamdani’s victory speech Tuesday night alluded to and remixed lines from socialists and liberal Democrats alike — including Cuomo’s father, New York’s former governor Mario Cuomo.
“A great New Yorker once said that while you campaign in poetry, you govern in prose,” Mamdani said, paraphrasing the elder Cuomo. “If that must be true, let the prose we write still rhyme, and let us build a shining city for all.”
So given all the notes he struck during the campaign, it is revealing to consider those Mamdani left unplayed. One in particular stands out: Throughout the long mayoral campaign, Mamdani rarely spoke about climate change — often doing so only when directly asked.
This might not seem meaningful on its face. Mamdani had a lot of issues he could focus on, after all. (He also spoke intermittently about, say, K-12 education, even though as mayor he will oversee the nation’s largest school district.)
But in light of his biography, Mamdani’s relative reticence on climate change stands out. During his early career in the state legislature, Mamdani defined himself in part through his climate activism, and by his view that New York should be “leading the country in our fight against the climate crisis,” as he said in a 2022 press release. He helmed some of the most aggressive recent activist efforts to shut down, block, and replace fossil fuel infrastructure in Gotham. They provide a window into where his mayoralty could go — and also illustrate the fraught politics of climate change in Year 1 of Trump 2.0.
From his first days in the New York State Assembly in 2021, Mamdani placed himself at the forefront of the debate over the future of fossil fuels in New York’s energy system. “When I ran for this office, it was on a platform of housing, justice, and energy for all,” he said in a statement soon after his election.
Many of his biggest policy proposals as a legislator focused on climate change. He backed the Build Public Renewables Act, a bill that empowers New York’s state power agency to develop wind and solar projects in order to meet the state’s climate goals. He resisted NRG Energy’s push to replace an aging natural gas peaker plant in Astoria, Queens, with a newer power plant that would still burn gas. And he opposed the expansion of natural gas pipelines into the state while cosponsoring the Clean Futures Act, which would, he said, ban all new natural gas power plants across New York.
Climate change was the issue, he said, at the very heart of his political identity. In July 2022, after the state assembly expired without a vote on the Build Public Renewables Act and amid a heat wave in New York, he called for a special session to pass the bill, deeming climate change a “human catastrophe.”
“There are a number of bills that I would love to pass tomorrow. I’m not calling for a special session for all of them,” he told Spectrum News. “The reason we have to call for this one is because climate change is not waiting.”
In its fight against the Queens power plant, his legislative office — working alongside the Stop NRG Coalition, an alliance of local residents, the Democratic Socialists of America, and traditional environmentalists such as Earthjustice and the Sierra Club — called 36,000 households and sent more than 7,800 postcards asking residents to reject the plant, Mamdani later said. Ultimately, locals filed more than 6,000 comments to oppose the proposed plant; when the New York Department of Environmental Conservation ultimately denied a key permit in October 2022, Mamdani claimed victory.
He was also clear about who had lost that fight: big corporations and fossil fuel-aligned capitalism. “This shows when we organize against corporations that put capital over the collective, we can win a world where we all live with dignity,” he said. “Stopping the Astoria power plant is an amazing victory towards a habitable planet and the clean future we all deserve.”
Many of Mamdani’s other climate efforts were ultimately successful. The Build Public Renewables Act passed in April 2023 as part of the state budget and was signed into law by Governor Kathy Hochul. The state has not passed the Clean Futures Act, although regulators have rejected other proposed fossil-fuel power plants across the state, citing its 2019 climate leadership law.
In a little-watched May 2021 video that gives a concentrated dose of Mamdani’s political vision at the time, he described himself not as a socialist, but as a “proud ecosocialist” who believed that electricity should be treated as a “public good.”
“Did you ever wonder why New York state only gets 5% of its energy from wind and solar?” he asked in the video. “It’s because of one word: capitalism.” The way to fight that capitalistic hold on energy production, he said, was with public power — government ownership and development of zero-carbon generation.
Even after those victories, Mamdani remained a proud champion of climate issues. As recently as a year ago, he suggested that activism and agitation around climate change was a key way that progressives could differentiate themselves from Trump in the eyes of the working class. At a rally in late November last year, shortly after a drought resulted in a rare brush fire that consumed 2 acres of the city’s beloved Prospect Park, he exhorted the New York Power Authority, or NYPA, to move faster to develop its pipeline of renewables projects — and framed credible climate action as essential to countering Trump’s rise.
“The climate crisis does not care about any of the reasons that are usually given so much weight in Albany. It doesn’t care if you want to blame the supply chain. It doesn’t care if a private company says it has reduced profitability. It cares only if you build out renewable infrastructure,” he said.
“If you want to know how to defeat the Donald Trump far-right movement, it’s by showing we actually have a workable alternative,” he continued. “Because if working class people can’t breathe the air, if they can’t afford to live in the city they call home because they can’t find a union job, and if they look around at their favorite parks being on fire, why would they trust us?”
“It is time to show them why,” he concluded. “It’s time for the Build Public Renewables Act.”
Mamdani has continued to push for NYPA to accelerate its renewables construction — he posted a video of the same rally to his Instagram feed in September, encouraging his followers to file public comments with New York state.
As recently as February 2025, he described New York City as facing an “existential moment of our climate crisis” at a candidate forum, and said that enforcing the city’s climate laws would require “taking on the real-estate industry.”
But in the months since, his earlier bold rhetoric — casting practical concerns as no object when it comes to climate action — has faded, and he has evinced more sympathy for landlords and homeowners who may bear decarbonization’s costs. He still describes climate change in existential terms, but has become far less likely to bring it up unbidden in his own speeches and media appearances.
As a major party mayoral candidate, too, Mamdani largely avoided framing climate action as a necessary antidote to Trumpism. When seeking to contrast himself with the president, he focused almost entirely on cost of living issues. In a Fox News appearance in October, Mamdani addressed Trump directly and said that he would work with him to address New Yorkers’ cost of living.
His campaign website’s only stated climate proposal is a “Green Schools” plan to renovate 500 public schools, turn 500 asphalt schoolyards into green spaces, and construct “resilience hubs” at 50 schools. Speaking with The Nation in April — in one of his few recent long-form interviews on climate policy — Mamdani set that plan within his broader campaign, saying “climate and quality of life are not two separate concerns. They are, in fact, one and the same.” Schools, he said, offer “an opportunity for comprehensive climate action.”
But his website has few other details about what climate actions he might like to pursue once he takes office as mayor. Indeed, the candidate who once blamed capitalism for New York’s failure to build renewables is now promising to establish a “Mom-and-Pop Czar” to cut fines on small businesses and speed up permitting. It also gives few clues about how Mamdani would handle decarbonization’s inevitable trade-offs. If achieving a faster renewables buildout led to higher energy prices for consumers and small businesses, what would he do?
Even in situations where his slogans could reasonably connect to some climate benefit, Mamdani did not complete the handshake. His website does not mention the pollution benefits of fast and free bus service, for instance, even though free transit in other campaigns has been described as a climate policy. His 25-minute victory speech, delivered to a jubilant crowd on Tuesday night, did not mention climate change at all.
Regardless of what he’s said, Mamdani will be required to take big actions on climate policy as mayor. The most significant will likely arise from an ordinance called Local Law 97, which requires New York City’s large buildings to reduce their greenhouse gas emissions by 2050. That law’s strict new set of pollution caps and penalties will start in 2029, and many landlords are set to pay big fines. During the second mayoral debate, Mamdani repeated that the “climate crisis is one of the most pressing issues facing this city,” and said he wants the law’s fines to be enforced. But he also added that “the city should make it easier for buildings to comply.”
Mamdani has also argued that the city and state should renew a set of tax breaks to make it cheaper for large residential buildings, like condos and co-ops, to meet the law’s targets, and has proposed creating a “one-stop shop” for Local Law 97 compliance in the city governance, according to his debate remarks and a memo about homeowner policy released by his campaign.
In replacing climate change with cost of living, Mamdani has moved closer to what appears to be an emerging consensus among his party. Recent autopsies of the 2024 election have argued that voters believed Democrats were too focused on issues like climate change and not enough on affordability or inflation. Mamdani’s relentless focus on near-term costs — and his embrace of clear, actionable, and frankly non-climate-related slogans — suggests that one young ecosocialist might now agree with them. His ultimate victory suggests that it wasn’t a bad gamble.
