Lawmakers in California have strengthened the state's commitment to clean energy by passing a bill to stop using fossil fuels entirely by 2045. The legislature passed S.B. 100 by 43 votes to 32, making California the second state to take such a step, following Hawaii. The bill now moves to a procedural vote in the Senate, and then to Governor Jerry Brown to sign it into law. Around 72 percent of the state's residents were in support of the move, according to polls cited by CBS.
