New York climate plan sets 30-year goal for 100% renewable energy

Solar panels on every roof. Parking meters that double as car chargers. Wind turbines towering above farm fields and ocean waves. Cars, home furnaces and factories converted to run on electricity from renewable sources.

A new law signed by New York Gov. Andrew Cuomo sets the nation’s most aggressive targets for reducing carbon emissions and is intended to drive dramatic changes over the next 30 years. It calls for all the state’s electricity to come from renewable, carbon-free sources such as solar, wind and hydropower. Transportation and building heating systems would also run on clean electricity rather than oil and gas.

But while the goals of the legislation signed Thursday are clear, details on how to achieve them are undetermined. It isn’t clear how much all this change will cost, or even whether it is all technically feasible.

Some critics call the plan impractical.

“It would require massive deployment of both onshore and offshore wind, which is going to be enormously costly,” said Robert Bryce, an energy specialist at the Manhattan Institute, a conservative think tank. “You already have local opposition to onshore wind that has stymied the state’s ability to build any new capacity.”

The Climate Leadership and Community Protection Act requires the state to cut greenhouse gas emissions to 85% below 1990 levels by 2050 and offset the remaining 15% with measures such as planting forests and capturing carbon for storage underground.

A new 22-member New York State Climate Action Council will have three years to come up with a “scoping plan” to recommend mandates, regulations, incentives and other measures.

The law will require utilities to get 70% of the state’s electricity from renewable sources by 2030. Last year, 26.4% came from renewables, according to a report by New York Independent System Operator, the nonprofit corporation that runs the state’s power grid.

“The legislation is going to shape the way we live, work and play going forward,” said Peter Iwanowicz, executive director of Environmental Advocates of New York, which supports the plan. “It transitions New York state’s economy entirely off fossil fuels to one powered by renewable energy.”

Massive wind farms off the coast of New York City and Long Island are planned to help the transition to green energy.

Combined, the two wind farms will have a 1,700 megawatt capacity, enough to power about 1 million homes, Cuomo said at the signing, where he was joined by former Vice President Al Gore.

“This is the most ambitious, the most well-crafted legislation in the country,” Gore said of the state’s new targets.

The bill calls for 9,000 megawatts of offshore wind capacity by 2035. It also calls for 6,000 megawatts of solar capacity by 2025, five times the current amount, and 3,000 megawatts of energy storage capacity by 2030.

The Climate Action Council will likely call for new building codes to increase energy efficiency and require heating and cooling systems using electric heat pumps that transfer heat between indoors and outdoors. There may be incentives to retrofit existing homes and buildings. The New York City Council this spring passed an aggressive climate bill of its own that would require energy-efficient building retrofits, with hefty fines for landlords who don’t comply.

Since transportation makes up a third of the state’s emissions, the climate council will likely call for an expansion of mass transit and an accelerated shift to electric vehicles, which the state now promotes with rebates and investments in charging infrastructure.

Ken Girardin, a policy analyst at the Empire Center for Public Policy, a spinoff of the Manhattan Institute, calculates the offshore wind buildout will cost more than $48 billion upfront and $1 billion in annual operating cost. At least 56 square miles of solar panels would be needed to hit the 2025 goal of 6,000 megawatts of solar capacity, Girardin said.

But the costs of wind and solar installations have been dropping, said Michael Gerrard, director of the Sabin Center for Climate Change Law at Columbia University. “It’s much more economical to build large amounts of wind and solar energy than even three or four years ago,” he said.

Mark Jacobson, an energy expert at Stanford University, led a 2013 study outlining how New York could transition to 100% renewable energy by 2030. It envisioned 4,020 onshore wind turbines spread across 1.5% of the state’s land area — 818 square miles. And solar farms would cover 463 square miles.

About a third less land area would be required with today’s technology, he said, but the buildout would still be staggering — especially in a state where land is expensive and local opposition has stymied such projects.

New transmission lines, which also generate local opposition, would be needed to tie new wind and solar projects to the electrical grid.

“It’s definitely going to cost ratepayers a lot more for reliable electricity,” said Gavin Donohue, president of Independent Power Producers of New York, whose members produce three-quarters of the state’s electricity. He said efficient, low-emission natural gas plants built in the last 10 years are needed to keep the lights on.

“To say we’re not going to have any fossil fuel by 2050 is preposterous,” Donohue said. “Are we not going to have airplanes or gas-fueled cars? Is everyone going to have to retrofit their houses?”

Other Democratic-led states have passed laws to reduce greenhouse gas emissions in response to the Trump administration’s efforts to roll back regulations on power plants and vehicles. New York is the sixth state to mandate 100% renewable energy sources in coming decades, after Hawaii, Nevada, New Mexico, Washington and California. But New York’s plan will get there first.

“It’s one of the strongest climate change laws in the world,” Gerrard said. “It’s a heavy lift, but not as difficult as coping with the effects of severe climate change if action is not taken.”
