San Francisco-based Pacific Gas and Electric Co. (PG&E) averaged 32.8% renewable-based power supplies for the electricity it distributed last year. California has set a goal for the major utilities like PG&E to hit 33% by the end of 2020. Because of its large hydro electric fleet and the state's only major nuclear power plant, PG&E had nearly 70% of its power supplies last year come from greenhouse gas-free resources. The company said it is well on the way to hitting a 50% renewable power goal by 2030 that was set by the state.
