As oil reserves run out, I believe we will find many different energy sources we can use. The first ones will be easy. Natural gas, solar and wind energy will be used. I think that nuclear energy will also be used more. I hope we can figure out how to use fusion instead of fission. Fusion is not as dangerous. We may also figure a cheap way to break water into oxygen and hydrogen and use the hydrogen, its byproduct is water. There are probably those we don't even know about yet that we will use, just as oil was not used until the late 1800's.
