How much coal, natural gas, or petroleum is used to generate a kilowatthour of electricity? The amount of fuel used to generate electricity depends on the efficiency or heat rate of the generator (or power plant) and the heat content of the fuel. Power plant efficiencies (heat rates) vary by types of generators (prime movers), power plant emission controls, and other factors.

&#; Heat rate is a term commonly used in power stations to indicate the power plant efficiency.The heat rate is the inverse of the efficiency: a lower heat rate is better. = While efficiency is a dimensionless measure (sometimes quoted in %) heat rate is typically expressed as Btu/kWh. This is because Watt-hours are more commonly used when referring to electrical energy and Btu is more …
