Planetary civilization is planetary, consuming all energy that is available from a neighboring star, or about 10 watts. A Type II civilization is stellar, consuming all the energy that their star emits, or 10 watts. A type III civilization is galactic, consuming the energy of billions of stars, or about 10 watts. Carl Sagan suggested defining intermediate values (not considered in Kardashev's original scale) by interpolating and extrapolating, according to his calculations, the modern state of the present human civilization is expressed by a value about 0.7. Theoretical physicist Michio Kaku, in a book, "Physics of the Future", published in 2011, stated
