Home energy use

By Dick Hill

The residential sector (again, using data from the Energy Information Administration, the statistical arm of the U.S. Department of Energy) consumes about 20 percent of total U.S. energy. About 5 percent is used in space heating, 2.6 percent air conditioning, 2.9 percent water heating, 1.3 percent regeneration, 2.4 percent lighting, 1 percent color television. Clothes washers, dryers, freezers, cooking, personal computers, furnace fans, boiler circulators, etc., do not, by themselves, reach the 1 percent level. But “other uses” reach the 2.8 percent level! Think hot tubs. The commercial use of refrigeration is just about equal to the residential use of refrigeration. In other words, the Shaw’s and Hannafords of this world use about as much energy for refrigeration as do households.
