Number: RL31188 Title: Energy Efficiency and the Rebound Effect Authors: Frank Gottron, Resources, Science, and Industry Division Abstract: Several measures in the 107th Congress seek to increase energy efficiency as a means to decrease dependence on foreign oil, cut electricity demand and to curb both air pollution and greenhouse gas emissions. However some claim that these measures may not be as effective as projected because of the rebound effect. The rebound effect is defined as the difference between the projected and the actual savings due to increased efficiency. Pages: 13 Date: Updated November 19, 2001
