A terawatt (TW) is a unit of power equal to one trillion watts. It is commonly used to measure large-scale energy production and consumption, such as that from power plants or the total energy demand of a country. For context, a typical household uses about 1 kilowatt (kW) of power, so a terawatt represents an immense amount of energy. In the context of renewable energy, solar power and wind energy are often discussed in terms of terawatts to highlight their potential contributions to global energy needs. The world’s total energy consumption is measured in terawatts, emphasizing the scale of energy required to support modern life.
