The Gore Challenge Starts Here | SolveClimate.com

How much solar power would it take to replace the 20% of US electricity powered by natural gas? About 311 GW of nameplate capacity would do the trick. Some more context: SolveClimate linked to a story yesterday about a proposal for the world's largest solar farm. It would produce 250 megawatts of power. We'll need 1,250 of those to replace the gas plants.

How much solar power to replace all the coal? About 761 GW. Gulp. These are big numbers.
