Watt-hour
A Watt-hour (Wh) is a unit of energy that measures the amount of electrical energy consumed or generated over time. One Watt-hour is equivalent to one watt of power used or produced for one hour. This unit is commonly used to quantify energy usage in households, industries, and various devices. For instance, a 100-watt light bulb running for 10 hours consumes 1000 watt-hours, or 1 kilowatt-hour (kWh). Watt-hours are essential for understanding energy consumption, billing in electric utilities, and managing energy efficiency.
Gigajoules
A Gigajoule (GJ) is a unit of energy equal to 1,000,000,000 joules. It is commonly used to measure very large quantities of energy, such as the energy consumption of cities, the energy production of power plants, and the energy content of large quantities of fuel. One gigajoule is the amount of energy required to apply a force of one newton over a distance of one billion meters, or the energy transferred when one gigawatt of power is applied for one second. Gigajoules are used in various fields, including energy production, industrial processes, and large-scale energy management, providing a standard measure for comparing substantial energy transfers and consumption.
