I am going to introduce you to an interesting idea proposed by Kardashev called the Kardashev Scale. Here is a quote from science fiction and fantasy writer Veronica Sicoe which has a great introduction to this concept:
In 1964, Russian astrophysicist Nikolai Kardashev figured that civilizations can be categorized by the total amount of energy available to them. He defined three levels of civilizations based on their capacity to harness and use power. These have since been expanded by another four (in light of the increasingly wild speculations spawned by marrying mathematics and theoretical physics).
The Kardashev Scale, as it is called, now lists 7 levels of civilizations based on their power consumption, and implicitly on their technological advancement and extension.
