Energy Conservation and Efficiency

Energy Conservation and EfficiencyTom Manning

“Relying solely on a cheap, painless technological fix to conquer oil addiction is like relying solely on methadone to conquer heroin addiction. Abstinence is needed, too. The energy equivalent is conservation, which is superior in every way to substitution.”Hendrik Hertzbert, New Yorker, February 2006

“Ritualistic calls by utopians, moralists, and environmental absolutists for energy conservation are utterly inadequate and doomed to failure.”

Robert Zubrin, “An Energy Revolution”, American Enterprise Online

“Energy efficiency measures can reduce the need for additional generation and transmission resources…. At times of peak demand, energy savings are estimated to exceed 4,000 MW (approximately eight mid-sized power plants). However, these savings would require significant additional investment in energy-efficiency programs… Additionally, this would require increasing residential and commercial building energy codes as well as energy efficiency appliance standards.” New Jersey Blue Ribbon Panel on Development of Wind Turbine Facilities in Coastal Waters, November, 2005

• All of our major fuels are mined, then refined• High density chemical energy (fuel) starts

with photosynthesis

What is our situation?

• All of our major fuels are mined, then refined• High density chemical energy (fuel) starts

with photosynthesis• We convert mined fuels into electricity or

other energy forms (mechanical energy, heat)

• Refining is cheap, conversion is costly

What are the implications of a transition from energy mining to

energy conversion?

• Refining is cheap, conversion is costly• The lower the quality of the source, the more

costly the conversion
