KILOWATT HOUR Meaning and
Definition
-
A kilowatt-hour, abbreviated as kWh, is a unit used to measure electrical energy consumption or production over a specific period. It is a compound measurement that combines power, measured in kilowatts (kW), with time, measured in hours. The kilowatt-hour is commonly used to measure the amount of electricity consumed or generated by various electrical devices, households, buildings, or power plants.
Specifically, a kilowatt-hour refers to the amount of energy consumed or produced when a device with a power rating of one kilowatt operates for one hour. For instance, if a 1-kilowatt device were to operate for ten hours, it would consume ten kilowatt-hours of energy. This can be calculated by multiplying the power rating (in kilowatts) by the duration of operation (in hours).
The kilowatt-hour is widely used in utility billing, as electricity providers charge customers for the amount of energy consumed. It helps quantify the energy usage patterns, enabling customers to understand and manage their consumption.
It is important to note that the kilowatt-hour is a measure of energy, not power. Power refers to the rate at which energy is being consumed or produced, while energy represents the total amount consumed or produced over time. The kilowatt-hour provides a practical way to express both concepts in a single unit within the context of electrical energy.
