The US Energy Information Administration reported that total residential housing energy use remained flat from 1980 to 2009. The total number of residential home increased from slightly more than 80 million to just over 115 million during that time. The energy consumption per housing unit dropped roughly 25% during that period. Better insulation and more energy efficient lighting and appliances helped lower the energy use even though the average housing size increased over that period.
