In late August, the California Legislature passed SB 100 (de Leon), which increases California’s renewable electricity (RPS) requirement from 50 to 60 percent by 2030. SB 100 also requires the California Public Utilities Commission to plan for 100 percent of the state’s electricity to come from RPS eligible or zero carbon power by 2045. These two provisions will help to keep renewable power growing in California and will force the CPUC to plan for a more diverse portfolio of resources to meet the 100 percent target in 2045.
Some energy advocates and environmental groups have been claiming that the U.S. can meet all its energy needs with solar, wind and energy storage. The National Academy of Sciences has released a paper that criticizes that view as likely to be dangerously expensive if achievable at all. The NAS paper strongly recommends the inclusion of bioenergy in a low carbon portfolio to provide power that is easily dispatchable (available when needed) and that can be carbon negative.
