LOS ANGELES (AP) - Gov. Jerry Brown has signed an ambitious measure to combat climate change by increasing California's renewable electricity use to 50 percent and doubling energy efficiency in existing buildings by 2030.
Brown signed the bill Wednesday after losing a political battle against oil interests as he attempted to also cut petroleum use by half in the state.
The governor and Democratic leaders blamed the defeat on a multimillion-dollar advertising campaign by oil companies.
Brown began the year setting the most aggressive greenhouse-gas emissions benchmark in North America.
He outlined the plan to cut petroleum use, boost renewable electricity production and double energy efficiency in existing buildings without specifying how California could achieve those far-reaching goals.
The final bill largely defers to state regulators to implement the programs.
