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 curta

Energy efficiency is increased when an energy conversion device, such as a steam turbine, undergoes a technical change that enables it to produce more heat or electricity from the same amount of fuel. This book brings together research and analyses which put this issue in perspective.
