The Kardashev Scale
The Kardashev Scale, ranks the technological capabilities of a civilization, according to the energy it is able to manipulate and exploit. The scale was invented in 1964 by the Russian astronomer Nikolai Semenovich Kardashev who was looking for signs of extraterrestrial life within cosmic signals and proposed a scale for ranking these hypothetical civilizations based on their energy consumption. So the Kardashev scale was developed as a way of measuring a civilization’s technological advancement based upon how much usable energy it has at its disposal. The scale has three types that follow the scale of astrophysical structures in our local universe. The basic calibration is based on 3 energy positions on the scale corresponding to the ability to fully manage the energy resources of a inhabited planet (Type I), the star of the respective solar system (Type II) and its galaxy (Type III). Other astronomers have expanded the scale to Type IV and Type V.
