Every year, the California Energy Commission releases its Renewable Portfolio Standard (RPS) report, which gives details about the mix of energy experienced by all utilities within the state during the preceding 12 months. The report for this year, released in November, shows that all three of the state’s investor-owned utilities — Pacific Gas & Electric, Southern California Edison, and San Diego Gas & Electric — are projected to derive 50% of their electricity from renewable sources by 2020. That is a full decade ahead of schedule. PG&E reports it used 32.9% renewable energy in the past year. The figure for SoCal Edison was 28.2%. San Diego Gas & Electric led the pack with 43.2% renewable energy.
