$ 1.7 Trillion

New Physical Supply = 25 Q
Avoided Supply = 70 Quads in 2005
If E/GDP had dropped 0.4% per year
Actual (E/GDP drops 2.1% per year)
70 Quads per year saved or avoided corresponds to 1 Billion cars off the road
5
How Much of The Savings Come from Efficiency?
Easiest to tease out is cars
– In the early 1970s, only 14 miles per gallons
– Now about 21 miles per gallon
– If still at 14 mpg, we’d consume 75 billion gallons more and pay $225 Billion more at 2006 prices
– But we still pay $450 Billion per year
– If California wins the “Schwarzenegger-Pavley” suit, and it is implemented nationwide, we’ll save another $150 Billion per year
Commercial Aviation improvements save another $50 Billion per year Appliances and Buildings are more complex
– We must sort out true efficiency gains vs. structural changes (from smokestack to service economy).
6
How Much of The Savings Come from Efficiency (cont’d)?
Some examples of estimated savings in 2006 based on 1974 efficiencies minus 2006 efficiencies
Beginning in 2007 in California, reduction of “vampire” or stand-by losses
– This will save $10 Billion when finally implemented, nation-wide
Out of a total $700 Billion, a crude summary is that 1/3 is structural, 1/3 is transportation, and 1/3 is buildings and industry.

A supporting analysis on the topic of efficiencyfrom Vice-President Dick Cheney
“Had energy use kept pace with economic growth, the nation would have consumed 171 quadrillion British thermal units (Btus) last year instead of 99 quadrillion Btus”
“About a third to a half of these savings resulted from shifts in the economy. The other half to two-thirds resulted from greater energy efficiency”
Source: National Energy Policy: Report of the National Energy Policy Development Group, Dick Cheney, et. al., page 1-4, May 2001
Cheney could have noted that 72 quads/year saved in the US alone, would fuel one Billion cars, compared to a world car count of only 600 Million

Goals Of SB 1
“… to install solar energy systems with a generation capacity equivalent to 3,000 megawatts …”
“… to establish a self-sufficient solar industry in which solar energy systems are a viable mainstream option in 10 years…”
“… to place solar energy systems on 50 percent of new homes in the 13th year … ”

Demand Response, Retail Pricing Pilot, and Advanced Metering Infrastructure
CPUC and CEC have been testing the impact of “CPP” (Critical Peak Pricing) on demand
– Two summers of tests ($10 M experiment). Results for residential customers
– 12% reduction when faced with critical peak prices and no technology
– 30% to 40% reduction for customers with air conditioning, technology, and a critical peak price.
PG&E and SDG&E will install advanced meters soon New Bldg. Standards (Title 24(2008)) will require smart meters and
“PCTs” (Programmable Communicating Thermostats) in all new buildings and major retrofits, starting late 2008.
