What Is A Kilowatt-hour (kWh) And What Can It Power?

What''s the difference between a kilowatt hour (kWh) and a kilowatt (KW)? A kilowatt (kW) is 1,000 watts and is a measure of how much power something needs to run. In metric, 1,000 = kilo, so 1,000 watts equals a kilowatt. A kilowatt hour (kWh) is a measure of the amount of energy something uses over time.
