Renewable energy breaks record in California

On April 30th, solar, wind and other renewables provided enough electricity to meet the needs within California’s Independent System Operator, which supplies about 80% of the state. More power was being generated at the time than was needed, so some was sent to other states.

Notes

Other renewables include geothermal, biomass, biogas and small hydroelectric power. Large hydroelectric and nuclear power are not considered renewable by the state of California. Total supply exceeds demand because some amount of electricity is lost in transmission and some is exported to other states.
