  2. CO2 Emissions in California: Historical and Projected 174 MM tons = 30%

  3. Buildings natural Non-Combustion Buildings gas (net) electricity 7% 15% 16% 22% 14% Industry electricity 6% Transportation Petroleum Industry natural 41% Industry gas Petroleum 7% 8% California’s CO2 Emissions by End-Use Sectors 2004 Total Emissions = ~500 Million Metric Tons CO2 (eq.)

  4. Annual Energy Savings from Efficiency Programs and Standards 45,000 ~15% of Annual Electricity Use in California in 2003 Or 0.5% per year over 30 years 40,000 35,000 30,000 25,000 Utility Efficiency GWh/year Programs at a cost of ~1% of electric bill 20,000 15,000 Building Standards 10,000 5,000 Appliance Standards 0 1997 1998 2000 2001 2003 1999 2002 1975 1977 1978 1980 1983 1985 1987 1989 1991 1992 1993 1994 1976 1979 1981 1982 1984 1986 1988 1990 1995 1996

  5. California IOU’s Investment in Energy Efficiency Forecast Crisis Performance Incentives Profits decoupled from sales IRP Market Restructuring 2% of 2004 IOU Electric Revenues Public Goods Charges

  9. Other Energy Strategies , 4% Efficiency, 17% Forestry, 20% Renewable Water Energy, 10% Efficiency, 1% Cleaner Power Smart Growth, Plants, 9% 15% Renewable Clean Cars, Fuels, 2% 28% Strategies for Meeting California’s CO2 Goals in 2020 Total Reductions = 174 Million metric Tons CO2 equivalent

  10. California Renewables Portfolio Standard • Designed to increase diversity, reliability, public health and environmental benefits of California’s energy mix. • Current legislative goal of 20% of retail sales from renewables by 2010; increase by at least 1% per year. • Some discussion of increasing the goal to 33% by 2020

  11. California Solar Initiative :“Zero energy” new homes • $ 3 Billion Dollars over 10 years • Current rebate of $2.80 per watt but tied to improved home efficiency for new homes • Goal of 3,000 MW within 10 years, mostly residential locations • A 2 kW Alternating Current PV system on a home with a 3 kW central air conditioning on an annual basis 7,500 kWh (typical new home in California) -3,000 kWh (PV output) 4,500 kWh remaining load -2,500 kWh reduction in load due to extraenergy efficiency 2,000 kWh (Net purchase of utility energy) • www.GoSolarCalifornia.ca.gov
