We were also told that cigarettes are not addictive and there are WMDs in Iraq. I have since stopped believing every piece of garbage for-profit companies like CNN, tobacco companies, and Big Oil tells me and let the facts speak for themselves.
Cellulosic ethanol --> http://en.wikipedia.org/wiki/Cellulosic_ethanol
The technology is in development, but is very close. With cellulosic ethanol, there would be no need to worry about food crops being grown for fuel and raising prices. I do not have all the facts on the drawbacks of this process, and if somebody would like to point some out, I would be happy to reevaluate my opinion, but it sounds like the best new fuel so far. So, the problem with rising food crop prices is solved (as far as I know)
Also, if something doesn't work, fix it. If the current pipes won't carry the new fuel, then we need to fix the pipes or replace them. Fuel processing companies that will be making biofuel will take care of that because it would make them more money. Problem solved.
The reason for biofuel is the demand for an alternative for storing energy cheaply and efficiently for transportation. Oil is a bad idea and has many shortcomings. Biofuel is the next best alternative. If anyone has anything better, I am open to discussion.
