Primary energy consumption: Primary energy consumption: Consumption of primary energy. The U.S. Energy Information Administration includes the following in U.S. primary energy consumption:
Primary energy consumption also includes all non-combustion uses of fossil fuels. Energy sources produced from other energy sources—for example, coal coke from coal—are included in primary energy consumption only if their energy content has not already been included as part of the original energy source. As a result, U.S. primary energy consumption does include net imports of coal coke, but it does not include the coal coke produced from domestic coal.
Note: In some EIA publications, conventional hydroelectricity net generation, geothermal electricity net generation, solar thermal and photovoltaic electricity net generation (both utility-scale and small-scale), and wind electricity net generation are converted to Btu using the average annual heat rate of fossil-fueled plants, under definitions used prior to September 2023.
Primary energy consumption expenditures: Expenditures for energy consumed in each of the four major end-use sectors, excluding energy in the form of electricity, plus expenditures by the electric utilities sector for energy used to generate electricity. There are no fuel-associated expenditures for associated expenditures for hydroelectric power, geothermal energy, photovoltaic and solar energy, or wind energy. Also excluded are the quantifiable consumption expenditures that are an integral part of process fuel consumption.
