Planetary civilization

A planetary or a Type I civilization is a civilization that would be global, likely having a tolerant worldwide society that functions through science and reason, and is capable of consuming all of the incoming energy from its neighboring star, or about 1017 watts for Earth.

A planetary civilization or global civilization is a civilization of Type I on the Kardashev scale. This type of civilization is likely to be reliant on renewable energy sources such as stellar power, as well as powerful non-renewable sources such as nuclear fusion. A Type I civilization's energy consumption level is roughly equivalent to the solar insolation on Earth (between 1016 and 1017 watts) – around 3 orders of magnitude higher than that of contemporary humanity (around 2×1013 as of 2020).
