Demystifying kW vs. kWh

At its core, a kilowatt-hour is a unit of energy. It is the ammount of energy that is consumed or produced by a devic with a power output of one kilowatt over the course of one hour. For example, a 100-watt light bulb that is left on for 10 hours would consume 1 kilowatt-hour of energy (0.1 kW x 10 hours = 1 kWh).
