Energy & the Kardashev scale - Deepstash

The Kardashev scale

.... is a method, proposed by Soviet astronomer Nikolai Kardashev in 1964,  of measuring a civilization's level of technological advancement based on the amount of energy it is able to use. 

The Kardashev scale has 3 categories:

  • Type I civilization, also called a planetary civilization, can use and store all of the energy available on its planet.
  • Type II civilization, also called a stellar civilization, can use and control energy at the scale of its planetary system.
  • Type III civilization, also called a galactic civilization, can control energy at the scale of its entire host galaxy.

Energetically, Earth is still in its infancy

The Earth is at 0.7 on the Kardashev scale. While the jump has been significant in the last 200 years the number has been stagnant for the past 50. This is an argument for a great planetary stagnation.

We could have been a planetary civilization in terms of energy output if we had embraced and developed nuclear energy. We could have lived the future the Jetsons predicted. But fears of nuclear bombs made nuclear a political debate and we stayed on fosil fuels and renewables.

Since energy is on everyone's lips after the invasion of Ukraine, I think it would be useful to think of the energy output as a planetary issue, as Kardashev proposed.

Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.


Don’t look further if you love learning new things. A refreshing concept that provides quick ideas for busy thought leaders.

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

Sean Green

Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.

Jamyson Haug

Great for quick bits of information and interesting ideas around whatever topics you are interested in. Visually, it looks great as well.

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!

Giovanna Scalzone
