The breakdown of the energy use in homes is changing. Air conditioning has become a much larger share of energy use in the past decade or so. In the last survey by the Department of Energy they found that 87% of homes use air conditioning having at least one portable unit. Most newer homes have central air conditioning.
In addition, the Department of Energy found that 90% of homes had at least one desktop, laptop, tablet, or smartphone, and 79% have more than one. Although U.S. homes have an increasing number of computers, the number of televisions per home is declining. In 2015, homes had an average of 2.3 televisions, down from an average of 2.6 televisions per home in 2009. More than twice as many households reported not using a television in 2015 compared to 2009. It seems that Americans are viewing entertainment on their phones, tablets and computers instead.
