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 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”

Energy Action Plan
The Energy Action Plan is driven by the Loading Order contained in the multi-agency Energy Action Plan. Since its enactment in 2003, the Loading Order has been integrated into the major CPUC decisions governing energy policy and procurement. Energy resources are prioritized as follows:
1. Energy Efficiency/Demand Response 2. Renewable Generation, including renewable DG 3. Increased development of affordable & reliable conventional
generation 4. Transmission expansion to support all of California’s energy
goals.

The Rosenfeld Fund at the Energy Foundation
Interests that I’d like to pursue with the Fermi Prize $375,0001. In the Developing World: appropriate technology which also reduces
carbon emissions Replacing Kerosene Lamps with LEDs and PV arrays Ultra violet water purification systems Efficient cook stoves for the Darfur refugee camps
2. Worldwide: Robust Building Technology Seismic resistant insulated panel construction White and cool-colored roofs Cool Communities
3. Support for Graduate Students in fields related to Energy Efficiency

LEDs Powered with Photovoltaics
Evan Mills at LBNL points out the following: If 1 billion people could replace kerosene lamps with LEDs, emissions would drop by the equivalent of 1 million barrels of petroleum per day

UV Water Purification
36
Ashok Gadgil at LBNL points out if UV treatment replaces boiling 10 tons of water per day, each system avoids 4 tons of CO2 per day
Meet / exceed WHO and US EPA criteria Energy efficient: 60 watts disinfects 1 ton / hour Low cost: 4 cents disinfects a ton of water Reliable, Mature components Can treat un-pressurized water Rapid throughput: 12 seconds Low maintenance: once every three months http://www.waterhealth.com/
Ultra Violet Water Purification for Villages in Developing World
37
In Nov.-Dec. 2005, he visited Darfur camps, and showed that with a $10 metal stove, and training to use it, only half the fuelwood is needed.
The stove saves fuelwood worth $160 annually for a refugee family
Since that time, Ashok Gadgil has improved stove efficiency by another factor of two
