An incandescent light bulb costs about 50 cents and lasts about 750 hours. If you were to leave a 100-watt bulb burning for 24 hours each day, 365 days per year, it would use 876 kilowatt hours per year. ( 1000 watts equals one kilowatt -C --kilo-- means a thousand.) A kilowatt-hour of electricity costs about 15 cents.
