  5. Electricity Use of Refrigerators and Freezers in the US compared to Generation from Nuclear, Hydro, Renewables, Three Gorges Dam and ANWR (Arctic National Wildlife Refuge) 800 Nuclear 700 600 500 Billion kWh per year 400 Conventional 150 M Refrig/Freezers Hydro 300 at 1974 eff at 2001 eff Used 50 Million 2 kW Existing Renewables 200 PV Systems Used 3 Gorges Dam Saved 100 0

  6. The Value of Energy Saved and Produced. This is previous figure re-stated in dollars with generation worth $.03/kWh and savings worth $.085/kWh) 25 Nuclear Dollars Saved from 150 M Refrig/Freezers 20 at 2001 efficiency 50 Million 2 kW 15 PV Systems Billion $ per year Conventional 10 Hydro ANWR Existing 5 3 Gorges Dam Renewables 0

  7. 3 Gorges Dam vs. added Appliances in 2010 3 Gorges: 18 GW x 3,500 hours/year = 63 TWh at wholesale Conclusion: Optimum appliances could save 35 TWh/year, about one-half of 3 Gorges generation in 2010. Savings at retail at least twice as valuable as wholesale, so economically equivalent to the entire 3 Gorges project. Source: David Fridley - LBNL

Annual Usage of Air Conditioning in New Homes in California Annual drop averages 4% per year 3,000 Initial California Title 24 2,500 Building Standards 100% California Title 20 2,000 Appliance Standards Estimated Impact of 1976-1982 2006 SEER 12 Standards kWh/YEAR 1,500 1,000 33% 1992 Federal Appliance 500 Standard 0 1970 1972 1974 1976 1978 1980 1982 1984 1986 1988 1990 1992 1994 1996 1998 2000 2002 2004 2006 Source: CEC Demand Analysis Office

  10. Estimated Power Saved Due to Air Conditioning Standards (1974 - 2002) (cont’d) • Peak Power for United States Air Conditioning ~ 250 GW • But standards cover only residential and rooftop units ~ 200 GW • Avoided GW: 67% of 200 GW = 135 GW • Comparisons: • California Peak Load ~ 50 GW • United States Nuclear Plants net capability ~ 100 GW • Cooler roofs will save another 10% of 200 GW • Flat roofs, new or replacement, should be white • To be required in 2005 California Building Standards • Sloped roofs, new or replacement, can be colored but cool • Each strategy saves 10%, so 20 GW total • Just switching a-c equipment located outside to white should save another 1%, or 2 GW

  12. Electricity Efficiency and Renewables in CaliforniaGoals of California Energy Action Plan 2003 • California kWh per capita is already flat compared to U.S. climbing 2%/yr. • New California goal is to reduce kWh per capita by 1% per year • Renewable Portfolio Standard: add 1% of renewables per year • Additional peak reduction of 1% per year by Demand Response when power is expensive or reliability is a problem • In total, goals aim to reduce electricity growth, increase renewables, and grow demand response

  13. The Transition to a Sustainable Future • Past investments in efficiency have reduced growth and saved money • In addition, future investments could significantly reduce world energy demand and carbon emissions • We now turn from a discussion of electricity to primary energy
