This report summarizes annual estimates of total consumption of major fuels such as coal, fuel oil, natural gas, gasoline, and diesel fuels. Estimates of the consumption of a number of other comparatively minor fuels are also included.

Portions of the NEDS data are reported to EPA by state agencies under the provision of Section 110 of the Clean Air Act and EPA Regulations, Title 40, Code of Federal Regulations, Part 51.321.
