Some of the 300,000 computer-controlled mirrors, each about 7 feet high and 10 feet wide, reflect sunlight to boilers that sit on 459-foot towers. The sun’s power is used to heat water in the boilers’ tubes and make steam, which in turn drives turbines to create electricity Tuesday, Feb. 11, 2014 in Primm, Nev. (AP)
A gigantic solar farm, biggest of its kind in the world, opened last week in the California desert. Three-hundred and fifty thousand huge mirrors reflecting sunlight on 40-story towers — to 1,000 degrees Fahrenheit up there — making steam, turning turbines, generating clean electricity. And we not build another one like it. Solar and other renewable energies are up against an era of cheap, fracked natural gas.
