California leads the United States in producing electricity from renewable energy sources that include solar (from the sun), geothermal (from heat within the Earth), and biomass (from plants and animals). The state is also one of the top producers of conventional hydroelectric power (renewable energy from moving water), and also has a vast supply of crude oil.
In large part, California can thank Pacific Gas and Electric Company (PG&E), which gets its electricity from a mix of greenhouse gas-free technologies making it 100% greenhouse gas-free. About 5.1 Million accounts across 70,000-square-miles of service area in California utilize Pacific Gas and Electric Company, a subsidiary of PG&E Corporation.
