New York mayor could unlock the city's biggest clean energy shift yet

On a chilly September night in Brooklyn, a church filled with climate organizers and renewable energy advocates gathered for what they saw as a turning point. Zohran Mamdani, elected as New York City's next mayor, wasn't there in person — but his victory felt like a validation of their years-long push for something radical: a power grid owned and controlled by the public, not corporations.

The campaign for public renewables had been building quietly in Albany for years, driven by progressive and socialist state legislators. But Mamdani's primary win suggested the moment had shifted. "The public renewables campaign was instrumental in Mamdani's primary win," said state Assemblymember Marcela Mitaynes. Now the question is whether he can actually deliver.

What the mayor can actually control

Here's the tricky part: the mayor's office doesn't directly run New York's power system. That's the domain of the New York Power Authority (NYPA), a state agency that has historically moved slowly on clean energy. But in 2023, the state legislature passed the Build Public Renewables Act, which requires NYPA to fast-track solar and wind projects to power 70% of New York by 2030. NYPA recently announced a plan to build 7 gigawatts of solar and wind capacity with battery storage — enough to power millions of homes.

What Mamdani can do is significant. His administration could mandate solar panels on city buildings, align permitting and zoning rules with clean energy priorities, and enforce Local Law 97, which requires large buildings to cut their emissions nearly in half by 2030. These aren't flashy moves, but they're the scaffolding that makes the bigger transition possible.

Johanna Bozuwa, executive director of the Climate and Communities Institute, sees this as the real opportunity. "I really see this as a key opportunity for the incoming administration to showcase the power of collaboration with an entity like NYPA, to leverage its power and relationships to decarbonize these schools," she said.

New York City remains far more dependent on fossil fuels than the rest of the state — partly because transmission infrastructure hasn't kept pace with demand. A coordinated push from City Hall and the state could change that. It could also lower energy bills for residents, which is why climate advocates keep linking the clean energy argument to cost of living. "We can't disaggregate climate from cost of living," Bozuwa said. "The Mamdani administration really has the opportunity to show what a new form of climate politics looks like, one that actually brings climate and cost of living together."

There are real obstacles. NYPA's 7-gigawatt plan has been criticized by some as insufficient to meet the 2030 targets. Financing is tight. And just days after Mamdani's election, Governor Kathy Hochul approved a permit for a fracked gas pipeline — a move that seemed to undercut the clean energy momentum.

But the infrastructure for change is now in place. NYPA has a track record of working with the city on energy projects. The state law exists. And for the first time, the city has a mayor who won partly because he promised to make this happen. What comes next will show whether that promise can become reality.
