Is Energy Efficiency Environmentally Friendly?

Abstract

This paper challenges the view that improving the efficiency of energy use will lead to a reduction in national energy consumption, and hence is an effective policy for reducing CO 2 emissions. It argues that improving energy efficiency lowers the implicit price of energy and hence make its use more affordable, thus leading to greater use. The paper presents the views of economists, as well as green critics of 'efficiency' and the 'dematerialization' thesis. The paper argues that a more effective CO 2 policy is to concentrate on shifting to non-fossil fuel fuels, like renewables, subsidized through a carbon tax. Ultimately what is needed, to limit energy consumption, is energy conservation not energy efficiency.

“…The end result in terms of saved energy is thus uncertain, and energy efficiency might not be an effective tool for energy conservation (see, e.g. Herring 2000). Drawing on Greene et al (1999), the direct rebound effect is estimated to approximately 20%.…”
