The point that seems to keep getting overlooked is the need for a good
portable energy carrier in our civilization (and irritatingly enough
gasoline and diesel are currently the best(pollution,global warming
aside)). You may be trying to imply that you are using more oil than
you are producing. But that may not be the case at all. In fact even if
more energy is required to produce ethanol than you get from it, it may
still be desirable to do but the energy required to produce it will
have to come from other sources. I do not claim that ethanol is a good
energy carrier but it might be and probably is better (much) than
hydrogen and may be cheaper to produce than non-petroleum based
gasoline.
