The Carl Sagan Formulation & Mathematics

Logarithmic Interpolation Formula

K = (log₁₀ P - 6) / 10

Where P is total continuous power consumption in Watts.

In 1964, astrophysicist Nikolai Kardashev proposed three integer civilizational tiers based on power consumption: Type I (10¹⁶ W), Type II (10²⁶ W), and Type III (10³⁶ W). In 1973, Carl Sagan introduced a continuous logarithmic scale to interpolate values between whole integers.

Current Step-by-Step Derivation (2025)

1. Annual Primary Energy: E = 166,754 TWh

2. Continuous Power: P = (E × 10¹² Wh) / 8,760 h = 19.036 Terawatts (1.9036e+13 W)

3. Power Logarithm: log₁₀(1.904e+13) = 13.2796

4. Sagan Scale: K = (13.2796 - 6) / 10 = 0.7280 ≈ 0.73

💡 Why 19%: Humanity's current power consumption of 19.04 TW represents 19.0% of the 100 Terawatt (10¹⁴ W) milestone, and 0.19% of full Type I (10,000 TW).

Nikolai Kardashev Civilization Tiers Reference

Type 0

Current

Sub-Planetary Civilization

Power: < 10¹⁶ W (< 10,000 TW)

Civilization extracts power from organic, chemical, and basic nuclear fuels. Humanity currently operates at ~19 TW (K ≈ 0.73).

Sources: Fossil fuels, fission, solar, wind, hydro, geothermal

Type I

Planetary Civilization

Power: 10¹⁶ W (10,000 TW = 10 PW)

Capable of harnessing all energy delivered to Earth from our star (~1.74×10¹⁷ W) or deploying widespread fusion and planetary-scale storage.

Sources: Global solar collectors, controlled thermonuclear fusion, antimatter, planetary geothermal

Type II

Stellar Civilization

Power: 10²⁶ W (100,000,000 PW)

Capable of capturing the total radiant energy output of its home star using megastructures such as a Dyson swarm or sphere.

Sources: Star-lifting, full Dyson swarm, artificial micro-black holes

Type III

Galactic Civilization

Power: 10³⁶ W

Controls and channels energy across the scale of an entire galaxy spanning hundreds of billions of stars.

Sources: Galactic core supermassive black hole extraction, gamma-ray burst harvesting
