It's always amazing to find out exactly how much electricity a device uses and how much that electricity costs.
A watt isn't very large. You can barely cook a pot of rice with a thousand watts if you leave it on the stove for an hour. That is a "kilowatt hour" (kWh) of electricity. Using a kilowatt hour costs about eight cents on average nationally (though rates around the country range from 4.5 to 17 cents per kWh). Here in Jamestown a residential kilowatt-hour of electricity costs 6.5 cents.
