Kilowatt Hour (KWh) – Defined

A measurement that appears on your electric bill to show your usage. One thousand watt-hours equal 1 kWh.  Practical info: A typical U.S. household uses approximately 27,022 kilowatt-hours of electricity per year. Ten 100-watt bulbs operating at full power for one hour would consume 1 kWh of energy.
