About These Units

Gigawatt (GW)

A gigawatt (GW) equals 1,000 megawatts or 1 billion watts. Gigawatts measure national electricity capacity, large power grids, and total generating capacity. US peak electricity demand is about 700 GW. Famous from "Back to the Future": 1.21 gigawatts.

Watt (W)

The watt (W) is the SI unit of power equal to one joule per second. Watts measure electrical power consumption (LED bulb: 10W, microwave: 1000W), light bulb brightness, and device power ratings. One kilowatt equals 1,000 watts. Named after inventor James Watt.
