Neither ethanol nor methanol has the potential to "replace" fossil fuels --
mostly because of the land constraints. But David Pimentel also says
that ethanol consumes more energy than it produces:
"Ethanol production is wasteful of fossil energy resources and does not
increase energy security. This is because considerably more energy, much of
it high-grade fossil fuels, is required to produce ethanol than is available
in the ethanol output. Specifically, about 71% more energy is used to
produce a gallon of ethanol than the energy contained in a gallon of
ethanol." Pimentel: http://hubbert.mines.edu/news/v98n2/mkh-new7.html
