The Kardashev scale is a Russian astronomer Nikolai Kardaschow from the 1964 level of development proposed categorization of extraterrestrial civilizations by their energy consumption.
In its basic form it has three categories, are classified in the civilizations on the basis of their energy production.
Type I: The civilization that is at the technological level of the current [ 1964] Earth with an energy consumption of 4.1012 W. This was later changed then that civilization is in a position to exploit the full power available on a planet. This is about 1016-1017 W. (For the Earth, this value is slightly larger than 1.74 · 1017 W).
Type II: Civilization is in a position to take advantage of the overall performance of their central star. That's about 4.1026 W.
Type III: Civilization is in a position to take advantage of the overall performance of a galaxy. That's about 4.1037 W.
Human civilization is currently below Type I, since we are only able to use a portion of the available power on earth. To replace the consumption of limited fossil resources through a wider use of solar energy, it also requires the humanity still significant development steps. The current status of human civilization is unofficially known as type 0th Although intermediate values in Kardaschows original proposal were not available, Carl Sagan, the current status of the people extrapolated to 0.7.
A possible key factor for the jump to Type I civilization is the massive use of methods of generating energy from ocean, wind power, solar energy and the use of geothermal energy. However, there is no known way to use the entire available capacity of the earth, without completely covered with artificial structures. In the medium term this is probably an impossible task. The growth of solar energy production during the last 20 years corresponds to a doubling every 18 months. If this trend would continue unchanged, I would, that is human civilization in 2041 a complete Type I civilization, and in 2113 achieved the status of a Type II civilization.
A hypothetical Type II civilization could use a Dyson sphere or a similar construct to use the full power of a star.
A Type III civilization could use the same methods as a Type II civilization, but extended to all stars of a galaxy, or it makes use of previously unknown agents.
