Stanford researchers have found that it’s “technically and economically” feasible to move California to an entirely clean energy system by 2050, using existing renewable sources like wind, water and sunlight. Published in Energy this week, the study concluded that the upfront capital costs would be more than offset by lower energy expenses. Bonus points: It could add 220,000 “manufacturing, installation and technology construction and operation jobs,” cut energy demand by around 44 percent, and eliminate billions in health costs linked to pollution. “If implemented, this plan will eliminate air pollution mortality and global warming emissions from California, stabilize prices and create jobs — there is little downside,” said Mark Jacobson, a Stanford professor of civil and environmental engineering, in a statement.
