How does humanity's power consumption in 2017 compare to a Type 1 civilization?

Humanity's power consumption in 2017 was 17.9 terawatts, giving a Kardashev score of 0.60.

What are potential pathways for humanity to become a Type 1 civilization?

Solar and nuclear fusion energy

Managing waste heat from nuclear reactors and energy absorbed from the Sun

Significantly alter societal norms, requiring innovative solutions to manage energy and heat dissipation

Nikolai Kardashev introduced a scale categorizing civilizations based on energy consumption, with Type 1 harnessing all energy from a star, Type 2 consuming energy comparable to a star's output, and Type 3 consuming energy similar to a galaxy.
Carl Sagan expanded Kardashev's concept into a logarithmic scale based on energy levels, with humanity's current consumption placing us at a Kardashev score of 0.60, requiring a significant increase to reach Type 1 status. This transition would necessitate innovative solutions to manage waste heat and energy absorption, potentially involving massive cooling systems or expanding civilization to other celestial bodies.

Nikolai Kardashev classified civilizations based on energy consumption in 1964.
Kardashev proposed a scale to quantify civilization advancement.
Type 1 civilization can harness all energy from its parent star, around 1.7 x 10^17 watts.
Type 2 civilization would consume energy comparable to a star's output, about 3.8 x 10^26 watts.
Type 3 civilization would consume energy comparable to a galaxy, around 5 x 10^36 watts.
Carl Sagan extended Kardashev's idea to a continuous scale based on logarithmic energy levels.
Humanity's average power consumption in 2017 was 17.9 terawatts, giving a Kardashev score of 0.60.
To reach type 1 status, humanity needs to increase power consumption by a factor of 10,000.
Various models predict different timelines for humanity to reach type 1 civilization status.
Solar and nuclear fusion energy are potential pathways for humanity to become a type 1 civilization.

To become a type one civilization, the challenge lies in managing both the waste heat from nuclear reactors and the energy absorbed from the Sun, leading to a warming planet. Two potential solutions are proposed: constructing a massive air conditioner to cool enclosed living spaces or expanding civilization to other planets and moons in the solar system to distribute energy dissipation and maintain cooler temperatures.
The transition to a Kardashev type one civilization would significantly alter societal norms, requiring innovative solutions to manage energy and heat dissipation. Scientists engage in theoretical exercises and calculations to envision the implications of such advancements, aiming to detect technosignatures of advanced civilizations through telescopic observations.
