Former Gov. Jerry Brown signed Senate Bill 100 into law Sept. 10, 2018. The ambitious bill commits the state to 100% carbon free electrical energy by 2045. There are key milestones along the way: 50% renewables by 2026 and 60% renewables by 2030. California has been ramping up its renewable portfolio standard since it was established in 2002 with the goal of 20% renewable energy by 2017. Four years later, the target was adjusted to 20% by 2010 and, in 2008, the governor moved the target to 33% by 2020. In 2015, the legislature passed SB 350, setting a new target of 50% by 2030. These incremental changes have made California a world leader in renewable portfolio standard targets.
