The majority of American homes now have at least 16 different electrical appliances. To find out how much it costs to operate an appliance, multiply the cost for a kilowatt-hour by the number of kwhr the appliance uses. While your usage of any appliance may not be the same as the average consumption listed, this calculation will Provide approximate operating costs. Using the pamphlet You and Your Electric Company follow the chart on Annual Energy Requirement. Kilowatt-hour rates vary widely.
Utilities list the rate for a kilowatt-hour on statements to customers.
The pamphlet How to Understand Your Utility Bill is an excellent reading guide which should be assigned as homework for parents and students. Each student should have received a copy by now. Basically the pamphlet explains such terms as the btu, cubic feet, watt, kilowatt, fuel adjustment cost, PGA, and rate schedule. The pamphlet is self-explanatory and vital, therefore I will not elaborate on its content except to mention some possible adaptations. For instance, the sample bill can be dittoed, and used as a study guide which will aid the explanation of the Calculating section.
