Watts
The watt (W) is the SI unit of power, defined as one joule per second. It is used to measure the rate of energy transfer and is commonly used in a wide range of applications, including electricity, mechanics, and heating.
Gigawatts
A gigawatt (GW) is equal to one billion watts. It is used to measure large-scale power output, such as the capacity of entire power grids or large power plants. Gigawatts are used in the context of national or regional energy production.
