Q & A from - Union of Concerned Scientists
"Q: Some critics say that ethanol is destined to remain a niche product in the Midwest, subsidized by Congress for the benefit of farm-state politicians. Is this charge justified?
A: If ethanol is to grow beyond its midwestern roots, we will need to develop new technologies to produce it more efficiently and from alternative feedstocks. The potential for cellulosic ethanol to help tackle oil dependence and global warming is there, but it will take a long-term commitment and improvements in vehicle efficiency for that potential to be realized. If politicians just use ethanol as a 'flavor of the month' to avoid taking real steps to cut oil dependence through higher fuel efficiency, it could end up as a bit player or even a drain on oil dependence (as we have seen with the dual-fuel loophole that provides automakers credits toward meeting fuel economy standards without requiring that flex-fuel vehicles run on alternative fuels)."
