The amount of fuel used to generate electricity depends on the efficiency or heat rate for the generator (or power plant) and Heat content of the fuel. Power plants efficiency (heating rates) vary according to the types of generators, power station emissions and other factors. Fuel heat content also varies.

Two formulas can be used to calculate the amount of fuel used to generate a kilowatt (kWh) electricity:

• Amount of fuel used per kWh = Heat rate British thermal devices (Btu) per. KWh) divided by Fuel Content (in Btu per Physical Unit)
• Kilowattour produced per. Fuel amount used = Fuel content (in Btu per Physical unit) divided by heat rate (in Btu per kWh)

Data sources for the calculations:

Electric Power Annual

Monthly Energy Summary , Appendix with fuel heat content, electric heating and conversion factors

You can calculate the average amount of fue I used to Generate electricity in the United States, in every state and in some power plants that use
