California Gov. Edmund Brown Jr. signed a 33 percent renewable energy standard into law on April 12.
The standard requires California’s investor-owned and municipal utilities to have one-third of their power generation come from renewable energy sources by 2020. The mandate also requires utilities to draw some of the electricity from distributed generation systems such as rooftop solar.
The state Assembly passed the legislature in March.
The California Air Resources Board had been responsible for implementing an executive order from then-Governor Arnold Schwarzenegger, which established the 33 percent mandate. However, rules set by the board are more easily undone than those approved by the Legislature. Schwarzenegger vetoed a similar bill in 2009.
