Planetary civilization modify the weather at will, harness the power of a hurricane, or have cities on the oceans. Although they roam the heavens in rockets, their energy output is still largely confined to a planet. On the Kardashev scale, the next status is Type II civilization, where a civilization consumes all the energy that their star emits, or about 10 watts. Michio Kaku in a book "Physics of the Future" suggests that humans may attain stellar civilization status in a few thousand years. Planetary civilization A planetary civilization or global civilization is a civilization of Type I on Kardashev scale, with
