Watt-Hour
A watt-hour (W·h) is a unit of energy equal to the amount of energy transferred or used when one watt of power is sustained for one hour.
History/Origin
The watt-hour was established as a practical unit of energy measurement with the adoption of the International System of Units (SI) and has been used in electrical and energy industries to quantify energy consumption and storage since the 20th century.
Current Use
Watt-hours are commonly used to measure electrical energy consumption in household appliances, batteries, and energy storage systems, providing a convenient unit for billing, capacity ratings, and energy management.
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.
