ok, Kilowatt hour is the unit of electricity consumed in homes, I confused it with electric current. but it is a unit of energy basically, not power. WATT is the unit of power. so correct answer is energy.

*The kilowatt hour, also written kilowatt-hour,
(symbol kW·h, kW h or kWh) is a unit of energy.
*It is most commonly used to express amounts of energy delivered by electric utilities, and it appears on electric meters and bills in some countries.

*The kilowatt hour is a measure of work, the watt is a measure of power. The amount of wattage times the amount of time is the amount of work done.

*It is not used in the International System of Units (SI). The SI unit of energy is the joule (J), equal to one watt second. The kilowatt hour is commonly used, though, especially for measuring electric energy.
