Science Concept: Paying for Power

Your local electric utility sends your household a bill for the electricity you use.

You pay for the kilowatt-hours (kWh) of electricity used in your home during the billing period. What is a kWh? It is equal to 1,000 watts of electricity used for one hour. If you leave ten 100-watt lightbulbs on for an hour, you’ve used one kWh of electricity.
