Power Profiler Allows Users to See Emissions, Electric Sources

EPA has updated its emissions and generation database, or eGrid, with 2007 data, allowing users to access the information using ZIP codes.

The U.S. Environmental Protection Agency updated its database that helps Americans understand the health and environmental impacts of electricity generation. EPA’s Emissions and Generation Integrated Resource Database (eGRID) and Power Profiler now include data from 2007, an update from 2005.

eGRID is a comprehensive database of emissions from almost all electric power generated in the United States. The data are widely used to show the impacts of electricity generation as well as the benefits from reduced electricity demand. eGRID contains emissions information for nitrogen oxides and sulfur dioxide, which contribute to unhealthy air quality and acid rain in many parts of the country. eGRID also contains emissions information for carbon dioxide, methane, and nitrous oxide, which are greenhouse gases that contribute to climate change.

Power Profiler is a user friendly online application that uses eGRID data to show air emissions information and the type of electricity generation, such as coal or nuclear, in various regions of the country. By simply entering a ZIP code and selecting a utility, users can learn more about where their electricity comes from and what impact it has on air quality and the environment.
