Energy Efficiency and Rebound Effect: Does Energy Efficiency Save Energy?(Report‪)‬

1. Introduction The energy issue has been crucially important for state economies, and (surely) it will sustain its importance in the future. Besides being a basic input for economies, energy is the determinant for the world economy in the fields of economical, social and geographical environment. Acquiring sufficient energy economically, safely and cleanly in a determined time is an important sign for countries to show their levels of development. The shocks experienced in energy prices in 1970s and the real wage fluctuations profoundly influenced state economies in some ways. One of these influences has been observed in using new technologies in order to minimize the energy input used in production process. The relation between energy efficiency and energy consumption has been a matter of several discussions among developed countries since 1980s. Brookes (1979), Khazzoom (1980), Saunders (1984, 1992), Schurr (1982) assert that; while the increases in energy efficiency at micro level causes decrease in energy consumption at micro level, it will cause an increase in energy consumption at national or macro levels [1-5]. This approach is named as Khazzoom-Brookes postulate. This thesis was first used (proved) by Harry Saunders in 1992. The studies related to this field were considerably influenced by the Jevons' study named "The Coal Question" [6].
