Over the past three decades, the share of residential electricity used by appliances and electronics in U.S. homes has nearly doubled from 17 percent to 31 percent, growing from 1.77 quadrillion Btu (quads) to 3.25 quads. This rise has occurred while Federal energy efficiency standards were enacted on every major appliance, overall household energy consumption actually decreased from 10.58 quads to 10.55 quads, and energy use per household fell 31 percent.
Federal energy efficiency standards have greatly reduced consumption for home heating
Total energy use in all U.S. homes occupied as primary residences decreased slightly from 10.58 quads in 1978 to 10.55 quads in 2005 as reported by the most recent consumption and expenditures data from the Residential Energy Consumption Survey (RECS). Updated energy consumption data will be available next year. A dramatic reduction in the energy needed to heat homes, along with other efficiency improvements, led to a 31 percent reduction in energy use per household. As a result, total residential energy consumption remained virtually the same.
