Gigajoule
A gigajoule (GJ) is a unit of energy equal to one billion joules, used to measure large amounts of energy such as in power generation and fuel consumption.
History/Origin
The gigajoule was introduced as part of the International System of Units (SI) to provide a standard measure for large-scale energy quantities, especially in scientific and industrial contexts, gaining prominence in the 20th century.
Current Use
Gigajoules are commonly used today to quantify energy in fields like energy production, consumption, and engineering, particularly for large-scale systems such as power plants, fuel storage, and energy audits.
Megawatt-Hour
A megawatt-hour (MW·h) is a unit of energy equal to one megawatt of power sustained for one hour.
History/Origin
The megawatt-hour has been used since the development of large-scale electrical power systems to quantify energy production and consumption, especially in power generation and grid management, becoming standard in the 20th century.
Current Use
It is commonly used today to measure electricity generation, consumption, and capacity in power plants, utilities, and energy markets worldwide.
