Energy efficiency is increased when an energy conversion device, such as a steam turbine, undergoes a technical change that enable it to produce more heat or electricity from the same amount of fuel. This contrasts with energy conservation and energy curtailment. The cumulative effect of energy efficiency can be enormous and significant in a country like the United States which uses so much more energy than it produces. This book brings together important research and analyses which put this critical issue in perspective.
