Under California's landmark 2018 clean energy law, the state is mandated to source 100 percent of electricity retail sales from renewable and noncarbon resources by 2045.
This will help slash global warming emissions and pollution from the energy sector, contributing to progress toward California's climate goals. The increasing number of climate-fueled extreme weather events and growing electricity demand—both of which are stressing the state's electricity grid—underscore the urgency of reaching 100 percent clean energy in a safe and reliable manner.
