California is among the world’s leaders in the development and deployment of renewable energy. Businesses, residents, and public entities in the state have harnessed significant amounts of solar, wind, geothermal, biomass, and other renewable sources, putting California on track to procure 33 percent or more of its energy from renewables by 2020 — the current statewide target. To meet its longer-term 2050 target (reducing greenhouse gas emissions eighty percent below 1990 levels), California will have to develop a vision and policies for renewable energy deployment beyond 2020.
