Rank Possible Advanced Civilizations According To Energy Consumption

By Dr. Michio Kaku

"A. A Type I civilization is truly planetary, using up all the energy from their sun which lands on their planet. They might, for example, be able to control all forms of planetary energy, such as controlling the weather and the power of hurricanes and volcanoes.

B. A Type II civilization has mastered stellar power, using up all the energy released from their mother star. They use up 10 billion times more energy than a Type I civilization. A typical example might be the Federation of Planets in Star Trek, which has harnessed the energy from only a tiny sliver of the stars in the Milky Way galaxy.

C. A Type III civilization is galactic, harnessing 10 billions more energy than a Type II civilization. They roam freely across the galactic space lanes. A typical example might be the Borg on Star Trek, or the Empire of the Star Wars series, or the Empire of Asimov’s Foundation Series."
