A terawatt-hour (TWh) is a unit of energy that represents one trillion watts of power used for one hour, and it equals 3.6 ×— 1015 Joules. This is equivalent to an impressive 3.6 million joules or 3.6 megajoules. This value is sufficiently large to represent the annual electricity generation of entire countries and is commonly used to describe significant energy production or consumption.
The value is equivalent to 1,000,000 megawatt-hours (MWh) or 1,000,000,000 kilowatt-hours (kWh) as well. One kilowatt-hour represents a consistent power of one kilowatt operating for a duration of one hour.
Applications of TWh
Terawatt-hours are a unit of measurement used to quantify the amount of electricity or heat generated. In practical applications, it is commonly employed to facilitate comprehension of large quantities of electrical energy.
For example, in 2022, electricity consumption in the United States is predicted to reach 4,010 terawatt-hours. The residential sector is responsible for a significant portion of this consumption, closely followed by the commercial sector. Heating and cooling appliances make up a significant portion of residential electricity consumption.
