The cost to use thatappliance can be determined fromthis label.In the example on this slide, the pieceof electronics is rated at using 65 wattsof electricity. If you used this appliancefor one hour, it would use 65 watt-hours of electricity.Electricity is sold by kilowatt hour, so youwould need to convert watts to kilowattsto determine the cost. If you used thisappliance for two hours, it would use 130watts of electricity (2 hours x 65 watts).
