Successes in Energy Efficiency
The state’s Building Energy Efficiency Standards have saved Californians billions of dollars in reduced electricity bills. They conserve nonrenewable resources, such as natural gas, and ensure renewable resources are extended as far as possible so power plants do not need to be built. Learn more in the Energy Almanac about how far we’ve come-and need to go-on the road toward a more resilient, affordable, equitable, and environmentally sustainable energy system.”
