Energy is back at the top of the news again.  Rising oil prices, a recent national commission recommending new policies, a gridlocked energy bill on Capitol Hill, and the continuing controversy over climate change have generated a new round of hand-wringing over energy policy not seen since the 1970s.  Fossil fuels, it is feared, are becoming scarce, or should somehow be made scarce.  In The Bottomless Well (Basic Books, January 2005), Peter W. Huber and Mark P. Mills shatter the conventional wisdom about energy, arguing that fossil fuel is abundant and energy efficiency mandates are counterproductive. Moreover, Huber and Mills explore the continuing revolution in energy technology, explaining why we can expect an energy-abundant future that will transcend the last drop of oil or lump of coal.
