In addition to this type of legislative framework and regulatory support, California’s energy efficiency model includes: n A “loading order,” which prioritizes reducing electricity demand through energy efficiency and demand response—ahead of renewable and conventional sources of energy n Decoupling gas and electric profits from energy sales—meaning PG&E does not make money through energy sales—which enables PG&E to aggressively pursue energy efficiency for customers without the prospect of a financial loss n Aggressive building codes and appliance standards that require Californians to build energy-efficient homes and commercial buildings n Ready availability of energy efficiency programs, training and strong customer interest PG&E’s energy efficiency programs have helped avoid the release of more than million metric tons of carbon dioxide (CO2) emissions based on cumulative lifecycle gross energy savings.
