In 2000, Home Energy Magazine Online published an interesting article by Jeanne Byrne on the amount of energy used by various appliances in the home.
About 61% of residential motor energy is used in space conditioning. Another 25% is used in refrigerators and freezers. Washing and drying--laundry and dishes--uses 6%. The remaining 8% is used in small appliances such as vacuum cleaners and hair dryers; drills, saws, and other power tools; and other applications.
Energy efficiency has certainly improved during the last 11 years but the essence of the article is still valid. For more information, go to the original article at Home Energy Magazine Online.
