This is a good video that talks about the “real story” behind the biofuels and ethanol debate. Many people are under the impression that biofuels are the answer to our current oil crisis. Scientist, David Fridely talks about how realistic it is to think about using corn, for example, to create enough biofuel to create an alternative to the oil we depend on today.
I found it interesting to learn that biofuel would have to be 99.5% pure in order to work in our engines and that corn would have to be grown no more than 250 miles from the source of use if it were turned into corn ethanol. This means that it would not be cost effective to ship over larger distances like we do with oil.
