The U.S. Environmental Protection Agency expanded the ENERGY STAR program to address industrial energy efficiency in 2000. Since then, the program has helped manufacturers strengthen their energy management practices and has engaged entire manufacturing sectors in focused energy efficiency efforts. The results demonstrate that energy efficiency is a cost-effective strategy for reducing GHG emissions in the manufacturing sector. This report discusses the origin of the ENERGY STAR program, its expansion into the industrial sector, the strategies used promote industrial energy efficiency and results.
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.
This report describes the work of EPA and the automobile manufacturing industry to develop an Energy Performance Indicator (EPI) for assembly plants. These types of plants are defined as those that produce passenger cars, light-duty trucks, sport utility vehicles, and vans in the United States. Learn how EPA uses EPIs to encourage industries to voluntarily improve their energy use. The report describes the data and statistical methods used to construct the EPI for automobile assembly plants. The equations are presented with instructions for using them in an associated Excel spreadsheet.
This paper from Duke University focuses primarily on the development of an updated ENERGY STAR industrial Energy Performance Indicator (EPI) for the cement industry and the change in the energy performance of the industry observed when the benchmarking system was updated from the original benchmark in 1997 to the new benchmark in 2008.
This document describes the data and analysis used to update the ENERGY STAR Energy Performance Indicator (EPI) for wet corn mills. The paper also compares the results of the original 1997 EPI with the updated analysis which is useful to someone who is interested in how the industry has changed during the last decade. The first section describes the data and the analysis used for the update. The second section compares the two models to show how the energy performance of this industry has changed over time.
