What would happen if the sun suddenly changed into a black hole (it would still keep it's same mass)? Well, actually, nothing would happen. The effects of black holes only become apparent if you get relatively 'very' close. In fact, every thing seems normal until you get to the boundry of the old sun. From there on out, the closer you get the stronger gravity gets. In the old sun, after crosing the boundry, gravity becomes weaker because particles on the other side of you cancel out some of the gravity. In the case of a black hole, however, there are no other particles to cancel out gravity, so you can get infinitely close and gravity will keep rising. Actually, you would probably have to be infinitely close to feel infinite gravity (We'll never know, unfortunately, because it's on the other side of the event horizon). Anyway, to get to your question, black holes probably don't have infinite gravatational energy. And larger black holes have more energy because their gravatational field occupies a larger area. So, I hope I actually did answer your question in all this blabber.
