| Grade three math to figure out KWH's Hi: Let's say my hydro costs 11 cents per kilowatt hour, all included and my toaster oven uses 1000 watts and it is in use for one hour...that would cost 11 cents?. How about my stereo which uses 250 watts, for one hour 11 divided by four=2.75 cents?. If I listen for four hours it costs 11 cents!!? Thanks, Huck |
