I disagree with your position. In the context of a discussion of
sustainability, which implies perpetuity, we cannot afford to dismiss the person
who wants to live within a sustainable energy budget. Those of us who choose to
ignore the fact that we are living on mined energy, should at least have the
ability to recognize the value of exploring alternatives that would allow us to
live within our means. From and energy budget perspective, this means finding
ways of surviving on the solar energy that arrives on earth daily.
Who knows, maybe more oil will be found, maybe we can stretch out our oil
consumption for another one thousand years. After that what? Pehaps the person
requesting information on ethanol production is not too late, rather, he may be
too early.
