Could a Black Hole Power Civilization?

In summary, a 44-year-old theory suggests that alien civilizations could potentially harness the power of a black hole. While the physics behind this idea is sound, it would be impractical for our civilization to use this method as it would require living in orbit around a black hole, which is currently not feasible. There are more feasible and sustainable ways of obtaining energy for our society.

The physics is fine. But as a practical idea it makes no sense unless you live in orbit around a black hole. Getting our entire civilisation from here to a black hole would be a tiny bit challenging. From where we are, there are far easier ways of getting energy in a sustainable manner.
