Just read a terrific article titled Toward a Type 1 Civilization by Michael Shermer."In a 1964 article on searching for extraterrestrial civilizations, the Soviet astronomer Nikolai Kardashev suggested using radio telescopes to detect energy signals from other solar systems in which there might be civilizations of three levels of advancement: Type 1 can harness all of the energy of its home planet; Type 2 can harvest all of the power of its sun; and Type 3 can master the energy from its entire galaxy.
Based on our energy efficiency at the time, in 1973 the astronomer Carl Sagan estimated that Earth represented a Type 0.7 civilization on a Type 0 to Type 1 scale. (More current assessments put us at 0.72.) As the Kardashevian scale is logarithmic -- where any increase in power consumption requires a huge leap in power production -- we have a ways before 1.0.
Fossil fuels won't get us there. Renewable sources such as solar, wind and geothermal are a good start, and coupled to nuclear power could eventually get us to Type 1."
To get an in depth view of the Kardashev Scale, click on the Dyson Swarm graphic. The information rocks.Enjoy
The question, as asked before in BRT, is Do We Have the Will?
