When will human beings become civilized? A new paper examines our limitations.

There are many ways to measure the progress of human civilization. Population growth, rise and fall of empires, our technological reach to the stars.

But one simple measure is to calculate the amount of energy that humans use at any given time. As human beings expand and develop, our ability to use our power is one of our most important skills.

Assuming that civilizations on other planets may have similar capabilities, the energy consumption of one species is a good measure of technological efficiency. This is the idea behind the Kardashev Scale.

Russian astronomer Nikolai Cardashev In 1964 he presented the measure. He divided civilizations into three categories: planetary, star, and galaxy.

Type I can use energy in proportion to the amount of star energy that reaches its home planet. Type II species can use energy on their home star scales, and Type III can use the energy of the home galaxy.

The idea was more popular with Karl Sagan, who simply suggested a continuous measurement rather than three types.

So what kind of civilization are we? Even though people use a lot of energy, we are not even qualified for that type.

On average, about 1016 watts of solar power goes to Earth, and humans now use about 1013 watts. At Sagan’s sliding scale, that puts us at 0.73.

It is not bad for many evolutionists, but it raises an interesting question. Can I get Type I? After all, we cannot capture all the sunlight on Earth, and we still have a planet to live on.

This question was recently addressed in an article on arXiv. The paper looks at the three major sources of energy: fossils, nuclear and renewable sources and calculates their growth over time.

On the one hand, access to Type I seems to be much easier. Make energy production your priority, and you will reach the end. But each type of power source has its limitations.

Worse yet, burning every ounce of fossil fuel as much as we can can lead to climate change, which could lead to a catastrophic catastrophe for all of us. If you are lost, you cannot be a civilization.

Therefore, the team analyzes the physical limitations of each energy source and follows a balanced approach in accordance with the framework of the United Nations Framework Convention on Climate Change and the levels of pollution.

They realize that even with limited limitations, human beings can reach level I. The damage did not reach that level until at least 2371.

That is not necessarily a bad thing. The Kardashev Scale is a blurred tool for measuring human technology.

While advanced civilizations require significant effort, we have seen how the advancement and efficiency of low-power computing can help us to reduce or stabilize our energy consumption as technology advances.

When this study shows how we can be like I, we can really walk when we realize we don’t need to.
