This report describes the data and statistical methods used to construct the Energy Performance Indicator (EPI) for corn refining plants. It also explains how the EPI was developed to provide a plant-level indicator of energy efficiency by working with the corn refining industry. This report is useful if you would like background information on how EPA's ENERGY STAR Wet Corn Milling Plant EPI was developed. The report presents the individual equations used to develop the EPI, as well as instructions for using them in an associated Excel spreadsheet.

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 PDF contains the entire 310-page Energy Independence and Security Act of 2007 (EISA). EISA lays the groundwork for federal agencies to increase the efficiency of products and buildings, promote research on and deploy greenhouse gas capture and storage options, and improve the energy performance of the federal government. Read this act to understand the federal government's initiative to prevent greenhouse gas emissions and protect our climate, part of which includes the use of ENERGY STAR benchmarking tools and resources.
