Overview
What is the Kardashev Scale?
Conceived by Soviet astronomer Nikolai Kardashev in 1964, the scale classifies civilizations by the total amount of energy they can harness. Carl Sagan later proposed a continuous interpolation formula so we can track progress between the major milestones:
K = (log₁₀(P) − 6) / 10
where P is power consumption in watts. Humanity currently sits at roughly K ≈ 0.73, well on the way to Type I.

K = 0.7290
P = 19.5 × 1012 W = 1.95e+13 W
K = (log₁₀(1.95e+13) − 6) / 10
K = (13.29 − 6) / 10 = 0.7290
