A Kilowatt-hour (kWh) is the standard measure of energy consumption for electricity in the U.S. and throughout the world. One kWh is the amount of energy needed to power a one kW device for an hour, or the energy needed to power 10 100-watt lightbulbs for an hour. Don't confuse this with electrical generation capacity, which is measured in the peak power that can be produced, in units of kW or MW (million watts). In general, for a gas or coal-fired power plant, one kW of generation capacity will produce between 6 and 8 MWh (6-8000 kWh) in a year's time.
