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
6
Environmental Equivalent of Avoiding 70 Quads
70 Quads = 33 Mbod (Million barrels of oil per day)
= 40% of World oil production of 80 Mbod
70 Quads = 1 Billion cars off the road, impressive since there are only 600 million cars on the road
7
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).
8
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.

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”

– Measured in lumens/watt Air conditioning standards
– U.S. split into regions based on type of weather
– Hot/dry west differs from warm/wet southeast
– With peak load as the focus, not seasonal efficiency— “SEER” White roofs on existing buildings Benchmarking of Commercial Buildings
– Fine tuning of energy management systems

Heat Mirror Windows – Steve Selkowitz, LBNL
Low Emissivity films are required by building standards world-wide. They reflect far infrared radiation. Retain indoor heat in winter, reflect outdoor heat in summer. They double the R-value of double glazing, and the inside pane is warm to the touch – more comfortable
Before low-E, windows were 30% of the heat load of a home – now 15%.
During a Montana winter, a north-facing low-E window, facing a snowy sunlit slope, is a net energy gainer.
“Selective film are required for Commercial Buildings in California. They reflect far- and near-infrared radiation, and halve the solar gain though windows; including car windshields in BMW’s etc.
Modern windows save ~1 Mbod of oil equivalent, = Alaskan oil.

Ashok Gadgil at LBNL points out if UV treatment replaces boiling 10 tons of water per day, each system avoids 3 tons of CO2 per day. An American car emits only 4 tons of CO2 per YEAR Cost of an avoided ton of CO2 is $0.35, vs. EU price of $20.
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 under lamp Low maintenance: once every three months >50 units now operating in India and Philippines http://www.waterhealth.com/

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

LEDs Powered with Photovoltaics
Evan Mills at LBNL points out the following: If 1.6 billion people could replace kerosene lamps with LEDs,
emissions would drop by the equivalent of 1.3 million barrels of petroleum per day
http://eetd.lbl.gov/emills/PUBS/Fuel_Based_Lighting.html The above estimate was for residential lamps only Including commercial uses, Mills estimates > 2 Mbod For comparison, U.S. gasoline use is 9 Mbod
