Highlight
Most of the utility-scale power plants that came online after 2010 were renewables or natural gas: solar (over 22 gigawatts from 2011 to 2022), followed by natural gas (slightly over 10 gigawatts), and wind (slightly under 10 gigawatts). Meanwhile, most of the power plants retired (about 18 gigawatts from 2011 to 2022) had been natural gas power plants (14 gigawatts), most of which began operations between the 1950s to the 1970s. In 2022, California achieved a momentous milestone by exclusively embracing renewable energy additions while simultaneously phasing out 35.8 megawatts of coal-generated power, according to the California Energy Commission (CEC).
