CT: A terawatt (TW) is a decimal multiple of the derived unit of power in the International System of Units (SI) watt, which is defined as one joule per second. Power measures the rate of energy conversion or the rate at which work is done. One watt is the rate at which work is done when an object’s velocity is held constant at one meter per second against constant opposing force of one newton. In electromagnetism, one watt is defined as the rate at which work is done when one ampere of current flows across a potential difference of one volt.
Example: In 2006 the installed capacity of all hydroelectric power generators in the world was approximately 1 TW.

N: 1. From tera- (prefix meaning “trillion,” used in forming large units of measure (such as terabyte), officially adopted 1947, from Greek teras “marvel, monster”) and watt (unit of electrical power, 1882, in honor of James Watt (1736-1819), Scottish engineer and inventor. The surname is from an old pet form of Walter and also is in Watson).
2. Terawatt (TW) is a metric measurement unit of power. The terawatt is equal to one trillion watts (1012W).
