Kardashev Scale
Where does humanity stand on the cosmic energy scale?
Humanity is currently at
0.727
on the Kardashev Scale
72.7% of the way to Type I · Estimated ~91.1 years to reach Type I
What if we had more power?

The Kardashev Scale Explained
Type 0 (K = < 0.7)
< 10^16 W
Civilization harnesses a fraction of its planet's energy. Uses fossil fuels, early nuclear, and renewables.
Think: Earth today (0.73)
Type I (K = 1.0)
~1.74 × 10^17 W
Controls all energy available on its planet — weather, volcanos, oceans, and full solar input. Zero fossil fuels.
Think: Earth in ~200-300 years?
Type II (K = 2.0)
~3.85 × 10^26 W
Harnesses the entire energy output of its star. Could build a Dyson sphere or swarm. Interplanetary colonization.
Think: Star Trek Federation level
Type III (K = 3.0)
~4 × 10^37 W
Controls the energy of an entire galaxy. Can manipulate space-time, travel between stars easily.
Think: Star Wars Empire level
Type IV (K = 4.0)
~10^46 W
Harnesses energy of the entire observable universe. Controls dark energy and cosmic expansion.
Think: Beyond current physics
Type V (K = 5.0)
~10^56 W
Transcends the universe itself. Harnesses energy from the multiverse. Essentially godlike.
Think: Pure science fiction
