Emissions and Generation Resource Integrated Database (eGRID)
From Open Energy Information
This tool is a comprehensive source of data on the environmental characteristics of electric power generated in the United States. These environmental characteristics include air emissions for nitrogen oxides, sulfur dioxide, methane, and nitrous oxide; emissions rates; net generation; resource mix; and many other attributes. This information enables policymakers and project developers to estimate the emissions reduction potential of renewable energy development in a given area.
