The EPA’s Emissions and Generation Integrated Resource Database (eGRID) is a “comprehensive source of data on the environmental characteristics of nearly all electric power generated in the United States.”
eGRID contains emissions and emission rate information for the following air pollutants and greenhouse gases: nitrogen oxides (NOx), sulfur dioxide (SO2), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and mercury (Hg).
The eGRIDweb application enables you to look at 2004 or 2005 emissions data by state, grid region, utility company, or specific power plant.
The EPA cites that “through eGRID, you can:
- Use emission rates for calculations based on electricity use (e.g., carbon footprinting, greenhouse gas inventories);
- Show the impacts of electricity generation and benefits of reducing the demand for grid-supplied electricity;
- Find out which plants emit the most and least pollution in the country; and
- Examine the emissions and fuel mix of different electric generating companies.”
