Interesting article here on Alternet.org.

After a steady stream of news out of Washington this past year that ethanol was going to cure all our woes, it's refreshing to hear some rational thoughts to the contrary.  Written by the Co-Directors of the International Forum on Globalization (www.ifg.org), the authors make some good points about the pitfalls of looking for biofuels to cure our dependence on oil noting that "corn-produced ethanol and many of the other biofuel varieties are leading us down a path of unsustainability as they continue to impact fragile ecosystems, threaten biodiversity, concentrate corporate power and increase inequities in rural communities."

I think a move away from corn based ethanol is an absolute necessity and sources like switchgrass and other cellulosic materials can provide a much more sustainable system of supply.  Ultimately, though, it is like the authors say, " "the answer must involve renewables plus significant efforts toward all-out conservation, efficiency, reduced consumption and "powering down" of energy use."
