I think that the question is too arithmetical: "Sauron has 100 energy units..." Role players and computer gamers are used to calculate magical force in "units", like life points, physical strength etc. But we should always remember that this is just a model. Nobody would really ask his physician about his life points, or his body building trainer about his strength points. So it is a little strange to wonder about Saurons energy units...
There is no principle of conservation of magical energy in Middle Earth! Magic is nothing that can be measured and calculated, it is some mystical power, far above our comprehention. (See the excellent article
Let’s Put the Magic Back in Magic by Ernest Adams about this subject. Well, it has been written for computer game developers, but you can also apply it to pen-and-paper RPGs etc.)
Perhaps Sauron has put some of his power into the ring in order to open a gate to some mystical source of power... The power of Mount Doom? A giant ring-dragon sleeping deep under the sea around Middle-earth? Or even Melkor Himself? Who will ever know?
