In a study published by Energy in June, a group of Stanford academics predicted that California will use only renewable energy by 2050. Mark Delucchi, co-author of the study and research scientist at the Institute of Transportation Studies at UC Davis, believes that California has the resources to become an all-renewable energy state but explained that it first needs the go-ahead from policy-makers. “There is a big difference between what is technically and economically feasible and what is politically feasible, and we recognize that,” Delucchi said. “Just because we show that it is technically and economically feasible doesn’t mean it is easy to do in a political sense – that’s a whole other matter.”
