In Carl Sagan estimated that humanity is currently around Type 0. He derived the following formula by interpolation:.
In humanity was using about 10 terawatts 10 13 W of energy. What was the Kardashev rating? A Kardashev Type 0 civilization would control 1 megawatt. If manual labor by one human being is about 17 watts 50 watts over an 8 hour day, 0 watts for the remaining hours , a Type 0 would represent about 60, manual laborers.
A Type In the total world energy consumption was about 13, mtoe , which is about , terawatt hours. This is the equivalent to an average power consumption of This would be Kardashev Type 0. A Type II would probably have some kind of Dyson sphere to harvest all the star's energy. Type III would probably be as far advanced from us as we are from one-celled amoebae. Terran space explorers would be wise to avoid areas where Type III civilizations are operating.
Otherwise they might suffer a similar fate to that of an ant trying to cross an interstate highway. And for similar reasons: not because the Type III hates lower races, but because the lower races are so far beneath their notice that Type IIIs cannot be bothered to keep track of them. Do you ever think about the ants you run over in your automobile? Even with a Type II the situation might be analogous to a puppy-dog chasing a monorail.
Keep in mind that while two cultures may be at the same Kardashev level, but have vastly different technological trees. Things might get worse if a human explorer succeeded in attracting the attention of a Type III. They might react as you would, reaching for a cosmic spray-can of insecticide.
Or use the explorer with the same lack of concern shown by cancer researchers to their laboratory rats. Maybe more like the lack of concern they show to the cells in their tissue cultures. It doesn't control the resources of this one planet, let alone a solar system or a galaxy. The Time Lords were the Type 4 civilization. We had no equals. We controlled the fundamental forces of the entire universe. Nothing could communicate with us on our level. Catherine: So much gets shipped up from Earth on commercial transports, it's hard to keep them out.
G'Kar [suiting words to actions]: I have just picked it up on the tip of my glove. If I put it down again, and it asks another ant, "What was that?

There are things in the universe billions of years older than either of our races. They are vast, timeless. And if they are aware of us at all, it is as little more than ants, and we have as much chance of communicating with them as an ant has with us! We know, we've tried! And we've learned we can either stay out from under foot, or be stepped on.
G'Kar: Yes. They are a mystery.

And I am both terrified and reassured to know that there are still wonders in the universe that we have not yet explained everything. Whatever they are, Ms. Sakai, they walk near Sigma They must walk there alone! G'Kar walks away. Catherine studies the ant for a moment and then turns away, shivering. The ant goes on about its own business. Robert A. Freitas Jr. As civilizations technologically advance, members of that civilization have access to increasing amounts of energy.
For example, your average medieval peasant could never hope to own something as destructive as an AK automatic rifle or a few drums of fuel oil mixed with ammonium nitrate. Imagine a family picnic. Some ants show up.

Little Billy gets annoyed, tracks the ants back to their nest, dumps a cup of kerosene onto it and lights a match. The ant nest is annihilated. Billy gets called back to the picnic for ice cream. Imagine a gathering of Type III entities. Some human starships show up. Little Beta-Lambda gets annoyed, tracks the starships back to Earth, and seeds it with five gigatons of neutronium antimatter.
Earth is annihilated. Beta-Lambda gets called back to the gathering for euphoronic frequencies.

Once an alien species advances beyond us humans by say, oh, several hundreds of thousands or million years, they enter Charles Stross' classification of " Weakly Godlike Entities. David Zindell's War in Heaven contains quite a few god-like entities who still occasionally notice humanity.
However they are mostly concerned with efforts to circumvent the restrictions place upon them by the other god-like entities in the area. For three million years, it had circled Saturn, waiting for a moment of destiny that might never come. In its making, a moon had been shattered, and the debris of its creation orbited still. Now the long wait was ending. On yet another world, intelligence had been born and was escaping from its planetary cradle.
An ancient experiment was about to reach its climax. Those who had begun that experiment, so long ago, had not been men - or even remotely human. But they were flesh and blood, and when they looked out across the deeps of space, they bad felt awe, and wonder, and loneliness. As soon as they possessed the power, they set forth for the stars. In their explorations, they encountered life in many forms, and watched the workings of evolution on a thousand worlds. They saw how often the first faint sparks of intelligence flickered and died in the cosmic night.

And because, in all the galaxy, they had found nothing more precious than Mind, they encouraged its dawning everywhere. They became farmers in the fields of stars; they sowed, and sometimes they reaped. The great dinosaurs had long since perished when the survey ship entered the Solar System after a voyage that had already lasted a thousand years.
It swept past the frozen outer planets, paused briefly above the deserts of dying Mars, and presently looked down on Earth. Spread out beneath them, the explorers saw a world swarming with life.
