Two issues involved with using "crops" for fuel: land and reliability of fuel supply.
Issue 1. Do you want your farmland used to produce fuel or food? As more farmland is turned over to producing fuel crops, less farmland is left to produce food, and the price of food will increase. Increasing ethanol usage has already impacted the price of food.
Issue 2. Oil can be pumped out of the ground as needed. Need more, pump more. Its reliable. Food crops are not reliable. They are susceptible to freezes, droughts, heat waves, water supply issues, insects, etc. Are you prepared for an un-relaible fuel supply?
