Green New Deal Part 4: How Much?
Is it possible to run New York on renewable energy alone?

We’re nearing the finish line at last. We know what we’re going to add to eliminate virtually all fossil fuels from New York state by 2030: new renewable power-generation assets capable of producing 600 million megawatt-hours of electricity per year.
We know what those assets are going to be: 20,551 new wind turbines, each rated at 10 megawatts (MW); 134,000 MW of solar generation, and; 117,000 MW of battery-storage capacity.
As an aside, in theory, one could reduce the number of wind turbines by adding more battery storage. The problem with that solution is that the capital cost of battery storage is about 50 percent higher than the capital cost of wind turbines, on a per-MW basis, according to the Energy Information Association (EIA). (Operating and maintenance costs are virtually identical.) Accordingly, green New York would get more expensive with more battery storage, so we’re packing in as many wind turbines as we can to “brute force†a solution.
