Residential energy efficiency has shown significant improvements over the past few years. In 2013, the U.S. Energy Information Administration (EIA) reported that heating and cooling – the long-standing energy hogs in American homes – no longer accounted for the major part of energy use in homes. Whereas in 1993, heating and cooling comprised 57.7% of total energy use, by 2009, their share had declined to 47.7%.
