What is jigawatts?

Jigawatts (abbreviated as GW or GWatt) is a unit of power, commonly used to describe the power output or consumption of large-scale energy facilities such as power plants. One gigawatt is equal to one billion watts, or 1,000 megawatts.

The term "gigawatt" became popularized through its use in the science fiction film trilogy "Back to the Future," in which a DeLorean time machine powered by a "flux capacitor" required 1.21 gigawatts of power to operate.

Currently, the world's largest power plant in China, the Three Gorges Dam, has a capacity of 22.5 GW, while a single wind turbine can generate between 1.5-7.5 MW, and a typical household consumes around 1-2 kW.

In the context of renewable energy, the term "gigawatt" is often used as a measure of progress towards reaching a global renewable energy target, such as the Paris Agreement goal of transitioning to a low-carbon economy with at least 50% of global energy demand supplied by renewable energy by 2030.
