The problem is that drawing energy out of crops is very inefficient. Plants are very good at generating the complex organic molecules we need to ingest in order to survive, but pretty inefficient when we just want lots of energy. We need safer/cleaner nukes, in my opinion, and electric cars/planes + maglev trains for mid-distance transport. Nukes provide bridge energy during this probably permanent oil problem; better solar should be the ultimate destination.
