Answer #1

Yup, it’s a scale of civilizations.

* Type I — A civilization that is able to harness all of the power available on a single planet, approximately 1016 or 1017 W. The actual figure is quite variable; Earth specifically has an available power of 1.74  × 1017 W (174 petawatts). (See Earth's energy budget.) Kardashev's original definition was 4  × 1012 W. (Kardashev had originally defined Type I as a "technological level close to the level presently attained on earth", "presently" meaning 1964).

* Type I — A civilization that is able to harness all of the power available from a single star, approximately 4  × 1026 W. Again, this figure is variable; the Sun outputs approximately 3.86  × 1026 W. Kardashev's original definition was also 4  × 1026 W.

* Type III — A civilization that is able to harness all of the power available from a single galaxy, approximately 4  × 1037 W.  This figure is extremely variable, since galaxies vary widely in size; the stated figure is the approximate power output of the Milky Way. Kardashev's original definition was also 4  × 1037 W.
Answer #2

I only know it was under a scheme for classifying advanced technological civilizations proposed by Nikolai Kardashev1 in 1964, thats all. You should ask professors for more information.
