   The Btu should not be confused with the Board of Trade Unit (BTU), an obsolete UK synonym for kilowatt hour (1 kW⋅h or 3,412 Btu). The Btu is often used to express the conversion-efficiency of heat into electrical energy in power plants. Figures are quoted in terms of the quantity of heat in Btu required to generate 1 kW⋅h of electrical energy.

   en.wikipedia.org/wiki/Energy_in_the_United_States

   [67] [68] Most of the energy used in homes was for space heating (34%) and water heating (19%), much more than the amount used for space cooling (16%) and refrigeration (7%). [69] Businesses use similar percentages for space cooling and refrigeration. They use less for space and water heating but more for lighting and cooking. [70]
