Terawatt (10¹² Watts)

Introduction : A terawatt is equivalent to 1 trillion (10¹²) watts. It’s a large-scale unit used to express global power production or energy needs on national or planetary levels.

History & Origin : Gained relevance in the 20th century as energy tracking evolved with global industrialization. Now widely used in discussions of energy policy, renewables, and climate science.

Current Use : Common in evaluating the world’s total energy consumption, estimating large grid outputs, or projecting the capacity of entire energy sectors like solar or nuclear power.

Erg per Second (CGS Power Unit)

Introduction : The erg per second is a CGS (centimeter-gram-second) unit of power. It defines the rate of doing work at one erg per second, equal to 1e-7 watts. Suitable for small-scale scientific and atomic-level measurements.

History & Origin : Introduced in the 19th century with the CGS system, the erg per second was widely used in classical physics, especially in electromagnetism and thermodynamics. It was eventually superseded by watt-based SI units.

Current Use : Primarily used in physics and astronomy to describe extremely small or precise power outputs, like light from a faint star or heat at microscopic scales. Still seen in theoretical or legacy scientific texts.
