San Francisco, September 13, 2012 — The California Public Utilities Commission (CPUC) said the energy efficiency programs approved by the CPUC resulted in savings of 5,900 GWh of electricity in 2010-2011 based on utility reported savings estimates, enough to power more than 600,000 households for a year and more than 1,000 MW, the equivalent of two major power plants.
In addition, the estimated savings cut carbon dioxide emissions by 3.8 million tons, the equivalent of removing more than 700,000 cars from California's roads.
In its 2010-2011 Energy Efficiency Annual Progress Evaluation Report the CPUC summarizes investor-owned utility implementation thus far of the CPUC's $3.1 billion 2010-2012 energy efficiency program.
The report details progress toward meeting multiple statewide energy and climate policy objectives including the Energy Action Plan, Assembly Bill 32, and the California Long Term Energy Efficiency Strategic Plan.
As outlined in the report, 89 percent of estimated energy savings reported through 2011 occurred in the commercial (55 percent) and residential (34 percent) sectors, with the agricultural and industrial sectors combined making up the remaining 12 percent of electric savings.
Through 2011, the majority of estimated electric savings was achieved through lighting (59 percent), followed by process improvements (13 percent), and HVAC (10 percent). Natural gas savings were primarily achieved in the industrial sector, where 47 percent of the estimated savings were generated through process improvements.
The report also includes information on counties in California with the highest energy savings in the state. Los Angeles County leads the way in electricity savings, while Contra Costa County shows leadership in the natural gas area.
