I don't skydive (can't afford it being a college student) but I've often worried about this problem. But here's one possible solution: check out the December 2005 Scientific American, in the Scientific American 50 awards section. Some people made an alcohol-powered crop duster and they said it would be possible to convert existing airplane engines to running on alcohol. Alcohol would be a renewable fuel because it can be made from corn.
