About Gigawatt (GW)

One billion watts, the gigawatt is used for national-scale power generation statistics and major infrastructure. The Hoover Dam produces about 2 GW at peak, and the Three Gorges Dam in China has a capacity of 22.5 GW. The famously quoted '1.21 gigawatts' from Back to the Future is actually a plausible lightning bolt power level.
