Summary
Recent controversy suggests that energy e$ciency policies used to reduce carbon emissions might actually increase overall energy consumption. The result would be an unintended increase in carbon emissions. This paper examines the underlying issues of this so-called `rebound e!ecta from both a historical perspective and through the results of a recent macroeconomic analysis completed for the United States. Depending on the assumptions of income and price elasticities, as well as the supply/demand interactions within a macroeconomic model, the rebound e!ect might reduce overall savings by about 2}3% compared to a pure engineering analysis. In other words, an economy-wide, cost-e!ective engineering savings of 30% might turn out to be [...]

Despite the impact of a rebound e!ect, the net result of energy e$ciency policies can be a highly positive one
