3 Gorges Dam vs. added Appliances in 20103 Gorges: 18 GW x 3,500 hours/year = 63 TWh at wholesale

Source: David Fridley - LBNL

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.

Estimated Power Saved Due to Air Conditioning Standards (1974 - 2002)

Peak Power for United States Air Conditioning ~ 250 GW But standards cover only residential and rooftop units ~ 200 GW

Avoided GW: 100 GW Comparisons:

– United States Nuclear Plants net capability ~ 100 GW– California Peak Load ~ 50 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

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 1/2% to 1% each 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

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 our discussion from electricity to primary energy Additional details will be available in Energy Efficiency and Climate
