If intensity dropped at pre-1973 rate of 0.4%/year
Actual (E/GDP drops 2.1%/year)
12% of GDP = $1.7 Trillion
7% of GDP =$1.0 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

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).

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 from transportation, and 1/3 from buildings and industry.
