Most California politicians have hated the zero-emissions electricity generated by nuclear power since 1976, when they passed a moratorium on new nuclear power plants. Nuclear is the cleanest, safest, proven, least-emitting fuel of all, and yet most of California’s politicians hate it. Once, California had multiple operating nuclear power plants, including San Onofre, Diablo Canyon, Rancho Seco, and partial ownership in Palo Verde, located in Arizona. Now, only Diablo Canyon and Palo Verde remain in operation.
