Actually, there is the theoretical possibility of using one to get energy - Microscopic black holes produce Hawking Radiation - the smaller the black hole, the more radiation produced. However, you can't readily control the rate of production (it is a function of the black hole's mass, which can be difficult to change). You could also capture energy by feeding the black hole matter - gas dropped into a black hole heats up to compensate for the gravitational potential energy loss, and hot gas produces light, some of which can escape the gravity well from the black hole.
Mind you, to get this energy, you have to be able to manipulate a small black hole, which is probably very difficult (if possible) and very dangerous.
