a Does not include electric power generation and distribution losses, which, if included, would triple the electric conversion factor given below,  and would increase the numbers in this row by about 20%.

KEY: Btu = British thermal unit; kWh = kilowatt hour.

NOTE: The heat equivalent factors used in Btu conversion are: diesel = 138,700 Btus/gallon; electric = 3,412 Btu/kWh.
