The Kardashev Scale and Civilization Energy Levels

The Kardashev scale, proposed by Soviet astronomer Nikolai Kardashev in 1964, categorizes civilizations into three stages based on their energy usage. A type one civilization can harness all the energy on its planet, including untapped sources like earthquakes and volcanoes. Type two civilizations can utilize the total energy of their star with a Dyson sphere. Type three civilizations have the ability to control energy on a galactic scale, encompassing billions of stars. The scale also includes speculative concepts like type four and type five civilizations, which involve capturing energy from the universe and alternate dimensions. We are currently not even a type one civilization. In 1973, astrophysicist Carl Sagan calculated that humanity was at a 0.7 on the scale in his book, Cosmic Connection.
