megawatt hour
- Definition: A megawatt hour (MWh) is a unit of energy equivalent to one megawatt (MW) of power used for one hour. It is commonly used to measure large-scale energy production and consumption.
- Symbol: The symbol for megawatt hour is MWh.
- Usage: Megawatt hours are commonly used in the energy sector to quantify the amount of electricity generated by power plants or consumed by large facilities over a specific period.
kilowatt hour
- Definition: A kilowatt hour (kWh) is a unit of energy representing one kilowatt (kW) of power used for one hour. It is widely used in residential and commercial electricity billing.
- Symbol: The symbol for kilowatt hour is kWh.
- Usage: Kilowatt hours are typically used by utility companies to measure and bill customers for their electricity usage.
Origin of the megawatt hour
- The term megawatt hour originated from the need to quantify large amounts of electrical energy produced and consumed. The prefix “mega” signifies one million, thus a megawatt hour represents one million watts of energy used over an hour. This unit became essential with the growth of large-scale power generation, especially in the 20th century.
Origin of the kilowatt hour
- The kilowatt hour emerged as a practical unit for measuring energy consumption in smaller scales, such as households and businesses. The term combines “kilo,” which denotes one thousand, with “watt hour,” indicating the energy consumed by one kilowatt of power over one hour. This unit became prevalent in the late 19th century as electrical grids expanded and residential electricity usage increased.
