"It seems obvious that rising efficiency in cars, furnaces, and lawn mowers should, in the aggregate, significantly curb demand for energy," write Peter Huber and Mark Mills in "The Bottomless Well," their perceptive 2005 book on the supply, demand, and pricing of energy. "Sad to say, however . . . efficiency doesn't lower demand, it raises it."

"Efficiency may curtail demand in the short term, for the specific task at hand," Huber and Mills acknowledge. "But its long-term impact is just the opposite. When steam-powered plants, jet turbines, car engines, light bulbs, electric motors, air conditioners, and computers were much less efficient than today, they also consumed much less energy. The more efficient they grew, the more of them we built, and the more we used them - and the more energy they consumed overall." ~Jeff Jacoby, in the Boston Globe, The Fuel-Efficiency Paradox
