Megajoule
A megajoule (MJ) is a unit of energy equal to one million joules.
History/Origin
The megajoule was introduced as part of the metric system to measure large amounts of energy, especially in scientific and engineering contexts, aligning with the SI units established in the 20th century.
Current Use
The megajoule is used in fields such as physics, engineering, and energy industries to quantify large energy quantities, including in energy production, consumption, and scientific research.
Gigawatt-Hour
A gigawatt-hour (GW·h) is a unit of energy equal to one billion watt-hours, representing the amount of energy produced or consumed over one hour at a power level of one gigawatt.
History/Origin
The gigawatt-hour emerged as a standard unit of energy measurement in the 20th century with the development of large-scale power generation and electrical engineering, facilitating the quantification of energy production and consumption in power plants and grids.
Current Use
Gigawatt-hours are used today to measure large-scale energy production, consumption, and capacity in power systems, renewable energy projects, and national energy statistics, aiding in energy management and planning.
