California has the largest state economy in the United States and is the fourth-largest electricity producer in the nation, accounting for about 5% of U.S. utility-scale electricity generation in 2021. Because more electricity is consumed in California than is produced there, about 30% of its electricity supply is imported, and 36% of its nuclear electricity supply is imported,
