Assessing Improvement in the Energy Efficiency of the U.S. Auto Assembly Plants

This 12-page paper describes the voluntary ENERGY STAR program policy approach selected to engage and motivate the automobile manufacturing industry to improve its energy performance, and the results of the industry’s efforts to advance energy management as measured by the updated EPI. Most notably, the paper shows that electricity use per vehicle in the best plants improved by 2 percent, while the fuel use per vehicle improved by a dramatic 12 percent.
