Amid the National Renewable Energy Laboratory’s (NREL) latest report1 on the land requirements of solar power generation, others are taking a look at what is really required to power homes using solar and wind and comparing that to another carbon free source, nuclear power generation.
A nuclear power plant, the biggest reactors currently available would take up less than 2 square miles and produce 3200MW of power.2 To achieve this same power output from solar would require 292 square miles, 146 times the amount of land required for a nuclear plant.2 A wind farm would need to be 832 square miles, or 416 times the land to create the same amount of power of the nuclear plant.2 To put this into perspective, the land footprints are shown over the backdrop of the state of Rhode Island, where the blue is a nuclear plant, the yellow a solar farm, and the green a wind farm all of equal capacity.
