Prices and Cost
Energy Saving Light Bulb The average cost of electricity in the United States is currently 11.88 cents per kilowatt hour (kWh) (for a more accurate cost, you can check your last billing statement for your cost per kWh), meaning if you used 1,000 watts of electricity for an hour, it costs you 11.41 cents.
Regular Bulb 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 – “kilo” means a thousand.) A kilowatt-hour of electricity costs about
15 cents.
