InsideClimate News reports that California Senate leader Kevin de Leon has introduced a bill that would require the state to go 100% renewable by 2045. If passed, the legislation would make California the second state (after Hawaii) to adopt a fossil-fuel-free electrical grid.

The legislation would also speed up California’s existing target — 50% of electricity from renewable sources — by five years to 2025. As InsideClimate News reports, the state is already well on its way to meeting this target, with 27% of its electricity coming from renewables last year.
