Attojoule
An attojoule (aJ) is a unit of energy equal to 10^-18 joules.
History/Origin
The attojoule was introduced as part of the SI prefixes to measure extremely small amounts of energy, particularly in fields like nanotechnology and quantum physics, as the need to quantify very tiny energy scales grew.
Current Use
The attojoule is used in scientific research to measure minute energy quantities, such as in nanotechnology, quantum computing, and molecular biology, where energies involved are extremely small.
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.
