A rotating black hole contains an enormous amount of energy, which an advanced civilization could hope to harness with up to 29% efficiency. There are two main mechanisms: the Penrose Process, which involves sending pairs of particles into a black hole's ergosphere and extracting one particle that gets spit out, and the Blandford-Znajek Mechanism, which extracts energy from a black hole's magnetic field as it interacts with its environment.
