By choosing renewables alone, the state may be closing off
other decarbonization pathways.
Last week, California’s quest for a clean grid
revolution culminated in the introduction of a bill mandating 100 percent renewable energy by 2045.
Senator Kevin de León, a longtime environmental leader in
the state senate, wrote the measure, which comes on the heels of last year’s
major greenhouse gas reduction bill. Massachusetts
legislators introduced the same goal with a deadline of 2035.
