The Kardashev scale is a great tool that has been looked at since the 1960's that was created by this particular scientist. The general thought behind this is, is that you can measure the power of a civilization by the way it can harness the energy around it.
When we think of power, we currently think of simple things like electric and various other forms this perhaps in your houses or even in the form TELSA cars.
But the power that is needed to truly harness in this world, is that in our solar system.
In a simple way, the human race is currently not a full TYPE I race. A TYPE I race according to Kardashev would be able to harness all the energy on its planet.
So far as humans we could say we are about 2/3's the way from that perspective idea -- or capability.
One way we could accomplish is to harness all the power in the center of the earth, or the oceans around us.
Now if we jump ahead a bit, as first mentioned, a TYPE III would be able to harness energy that you might even imagine. That would be in the form of other solar systems itself!
The ability to hardness not only the stars around us, but the entire solar system and utilize its energy for vast space travel.
It is rather hard to think about Humans coming up with such power, but once has to think is there another race out there that has achieved that type of energy power?
