How Much Energy Is Used to Heat and Cool American Homes?

Almost half of the energy used in American homes is for heating and cooling. Before 2009, more than half of all energy used in American homes was for heating and cooling. In 1993, for example, about 58% was used to heat and cool the homes. This reduction in energy used for temperature control is thought to be the result of several factors, including improved window performance, better insulation in homes and more energy-efficient heating and cooling equipment.
