Abstract

Energy efficiency is no longer a new term for the public. Over the past four decades, the concept of energy efficiency has been more and more accepted and used by the society worldwide. Along with energy efficiency, some other relevant terms such as energy conservation, energy intensity, and energy savings have also been frequently used. This chapter presents a brief introduction on these terms and a short description on relationship among energy efficiency, climate change, global energy demand, and national energy security. This chapter also introduces the concepts of energy efficiency gap, low hanging fruits of energy efficiency, and energy efficiency barriers.
