The Electricity Database Files Web site from the Department of Energy's Energy Information Administration division contains several helpful resources. The site's two main categories are entitled Electric Generator Databases and Power Plant Databases, which contain more than a dozen links to related information. These include everything from an Annual Electric Generator Report, Electric Utilities Database, and a Wholesale Electric Trade Database, to a Clean Air Act Database Browser that provides information about electricity generators that must comply with the sulfur dioxide provisions of the Clean Air Act Amendments of 1990. This unique and informative collection, besides being easy to access, makes utilizing the information simple by allowing users to download the files as either Microsoft Access or Excel files.
