In Winning the Oil Endgame: Innovation for Profits, Jobs and Security (Rocky Mountain Institute, Snowmass, Colo., $35), Mr. Lovins shows us the path to reduce our oil consumption. How much? How fast? Think about this timetable:

• Cut consumption by the amount we import from the Persian Gulf by 2015.
• Use less oil by 2025 than we used in 1970.
• Import no oil at all by 2040.
• Use no oil at all by 2050.

More impressive, much of this can be done simply by getting back on the efficiency improvement path we were on when we responded to the first and second OPEC oil price shocks in 1973 and 1979.
