Napalm, check out this website and scroll to the bottom and open the PDF with ethanol energy balance. So far I think the sun's energy is free but some of the idiots you choose to believe have it in the energy equation. Around here there is a lot of livestock fed by-products from the ethanol plant. The manure is put back on the land to fertilize the next crop saving commercial fertilizer. Us farmers aren't out doing as much tillage as before,hybrids are way better,the only problem I see is one guy can do so much it has reduced the farm labor needed to about nothing.
