The correct answer is Kilowatt hour (kWh)

Key Points

The commercial unit of electrical energy consumed is the Kilowatt hour (kWh).
One kilowatt hour is equivalent to the energy consumed by a 1000-watt appliance running for one hour.
It is commonly used by electric utility companies to measure and bill energy usage of consumers.
1 kWh is equal to 3.6 million joules (J).

Additional Information

Joule (J) is the SI unit of energy, but it is not practical for measuring large amounts of electrical consumption.
Volt (V) is the unit of electric potential, not energy.
Watt (W) is the unit of power, which is the rate of energy consumption.
Electricity meters in households typically measure energy consumption in kilowatt hours (kWh).
