the fact that it can be made from a renewable resource is what i think is important. gas prices are only going to keep going up as oil gets harder to find, butanol will probly either stay at a fixed price or go down as more and more companys start produceing it. last year i was only paying around 80 cents a liter for gas, this year its been as high as $1.24 (canada). thats quite a big jump in price for a year, i can only imagine how high its gona get in the next couple years.
