California continues to establish itself as a leader in solar energy innovation and pro-solar policymaking, nationwide. Many of these efforts have taken place at the state level. Witness the passage of California bill AB 510, which boosted the state's cap on net-metering for solar power installations. But county and city governments have played a prominent role, too. Recently GetSolar has detailed the following: a 95-kilowatt photovoltaic (PV) system that helps Santa Monica's Big Blue Bus transit system offset its carbon emissions; eSolar's Suntower Plant in Lancaster, Calif., which was recognized as 2009's best renewable and sustainable project; and the California solar powerhouse that is San Diego, which boasts more rooftop solar installations than any other American city. But these stories only tell the southern half of the California solar tale.
