Nataliya [291]

Answer:

Kilowatt-hour

Explanation:

Energy refers to the amount or quantity of power which is being consumed by an individual, group of people or organization over a specific period of time. As the consumers continue to use energy, they're being charged or made to pay a utility fee regularly for their amount of consumption, which is usually calculated hourly (kilowatts hour or kwh).

Hence, power utility companies use kilowatt-hour (KWh) per month, to determine how much energy is being used.
