Space heating and water heating account for nearly two thirds of U.S. home energy use

Space heating and water heating were the top two energy-consuming uses in U.S. homes in 2015, according to EIA’s latest Residential Energy Consumption Survey (RECS). Space heating consumption can vary considerably by climate and building characteristics, while variation in water heating consumption is driven primarily by the number of occupants in a home. Households use a variety of fuels for space heating and water heating, which affects these end-use shares of household energy expenditures.
