Civ 4 global warming
The energy use would then be comparable to the luminosity of the Sun, about 4 ×10 33 erg/sec (4 ×10 26 watts). Lemarchand stated this as a civilization capable of using and channeling the entire radiation output of its star. Type II A civilization capable of harnessing the energy radiated by its own star-for example, the stage of successful construction of a Dyson sphere or Matrioshka brain-with energy consumption at ≈4 ×10 33 erg/sec. Lemarchand stated this as a level near contemporary terrestrial civilization with an energy capability equivalent to the solar insolation on Earth, between 10 16 and 10 17 watts. Currently, the civilization of Type I is usually defined as one that can harness all the energy that falls on a planet from its parent star (for Earth–Sun system, this value is close to 1.74 ×10 17 watts), which is about four orders of magnitude higher than the amount presently attained on Earth, with energy consumption at ≈2 ×10 13 watts. Type I Technological level of a civilization that is "close to the level presently attained on Earth, with energy consumption at ≈4 ×10 19 erg/sec" (4 ×10 12 watts). In 1964, Kardashev defined three levels of civilization, based on the order of magnitude of power available to each:

This is the first 3 of 6 parts of the Kardashev scale. The scale has three designated categories.
