Definition
A traditional unit of heat energy equal to the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit — approximately 1,055 joules. In the electric power industry, Btu is used to express fuel energy content, plant heat rates, and the thermal output of cogeneration facilities. One kilowatt-hour of electricity is equivalent to approximately 3,412 Btu, a conversion useful when comparing electric energy to fuel energy in efficiency and emissions analyses.
