Already on a fast-track to building a reliable renewable energy infrastructure, California may soon set its sights on a future that is totally fossil fuel-free. Last week, right at the deadline for new bills, California State Senate President pro tem Kevin De León introduced legislation that will hasten the state's shift to renewable energy. Senate Bill 584 will push up California's shift to 50% renewables by 2025 (five years sooner than our current goals) and 100% by 2045.
