The Appliances contest is designed to reproduce appliance energy use in the average U.S. home. To earn points, student teams must maintain certain temperature ranges in their refrigerators (34°F/1.11°C to 40°F/4.44°C) and freezers (-20°F/-28.9°C to 5°F/-1.5°C). During the competition, they must wash and dry 12 towels for 2 days; cook and serve meals for 4 days; clean dishes using a dishwasher for 4 days; and operate a TV/video player for up to 6 hours and a computer for up to 8 hours for 5 days. Points are awarded for this contest through task completion.
