U.S. Home Energy Use
As High as in 1970s, Despite Advances
The average American household uses the same amount of energy it did in the early 1970s
, despite significant improvements in the efficiency of household appliances, according to a report in the Washington Post
. Even though appliances such as dishwashers and refrigerators now use half the amount of energy that they did several decades ago, average household energy use has remained the same because houses have been getting bigger and because they now contain more power-hungry devices, such as computers, flat-screen televisions, video games, and digital video recorders. One sign of that growing demand from computers, TVs, and other gadgets is that while electricity accounted for 23 percent of an average household’s energy use in 1978, it now accounts for 42 percent, according to the Post
. Even though household energy use has essentially remained flat for the past 40 years, the number of households has increased significantly as the U.S. population has grown from 203 million in 1970 to nearly 310 million today, pushing up overall energy use.
