Thanks. I thought this person had identified some really interesting topics for study, and I thought he was correct in his reasoning that: > >Explaining why he conducted the study, Dukes wrote: "Fossil fuel consumption >is widely recognized as unsustainable. However, there has been no attempt to >calculate the amount of energy that was required to generate fossil fuels, >(one way to quantify the 'unsustainability' of societal energy use)." I wonder as to the details of how he arrived at the very extreme-seeming figure that: ' >only about one-10,750th of the original carbon in ancient plant material >actually ends up as oil This was an assumption that seemed worth questioning. His final discussions of biofuel energies were also interesting to me. Some biofuel proponents will disagree with his ideas, but so be it. I liked the fact that he has chosen to examine these issues, and has illustrated the apparent inefficiency (in one sense) of fossil fuel use of solar energy. ------------------------ Yahoo!
