WASHINGTON, DC, July 2, 2007 (ENS) - The U.S. Environmental Protection Agency has added greenhouse gas emissions data to its online calculator that shows householders how much air pollution results from individual electricity use, the fuels used to produce that electricity and ways to reduce the impact.

'EPA's Power Profiler makes it easy to research the air emissions that come from using electricity at home,' said Bob Meyers, acting assistant administrator for EPA's Office of Air and Radiation. 'All you need is a ZIP code and you're on your way to understanding your environmental impact. '

EPA has updated the Web-based Power Profiler with recently released data on emissions and fuels. In addition to learning the emissions from their individual electricity use, users can see how they compare with national averages.

The air emissions used in the calculator are the greenhouse gas carbon dioxide, CO2, and the acid rain and smog forming chemicals sulfur dioxide and nitrogen oxides.

Power Profiler displays the fuel mix in percent coal, oil, gas, nuclear, hydro-electric, and other renewable sources such as biomass, wind, solar, geothermal, and landfill gas.

With information from the calculator on their monthly electricity use, consumers can assess their annual emissions.

The site also guides users to other Web-based information showing how to reduce emissions from a home or business through greater energy efficiency and use of renewable energy.

Power Profiler uses information from EPA's Emissions & Generation Resource Integrated Database, eGRID, a comprehensive source of data on the environmental characteristics of nearly all electric power generated in the United States.
