'Today, about a third of California’s electricity comes from renewables, including solar, wind, geothermal, biomass and small hydropower dams. Solar installations, in particular, skyrocketed. In just five years, solar went from less than 1 percent of California’s in-state electricity generation in 2012 to over 11 percent in 2017. But electricity from natural gas has also held steady. In 2017, it represented more than 40 percent of California’s in-state generation.'
