crops inefficient as biofuel
Using corn for biodiesel ethanol: "'You put in nearly as much energy into producing energy than you get out of it. It doesn't actually make a lot of sense,' he said."
Anyone hoping to live sustainably by switching to biodiesel would do better to use waste products, which scientists are investigating the lucrativeness of.

There is no such thing as "biodiesel ethanol." Biodiesel and ethanol are two different products. Biodiesel has the highest energy balance of any fuel available today according the the exahstive EPA/DOE fuel lifecycle anaysis of 1998.
You're right. I always get the two mixed up.
I was referring to bioethanol, but I always thought biodiesel was the same thing, then I realize that diesel can't be used in normal car.
So, from what I understand, bioethanol from corn is inefficient, but biodiesel from a variety of vegetable oil might be best, as long as those vegetable oil is waste product, not newly photosynthesized from plants.
