Bio-Desiel is very important too anything that is real and can challenge oil is good. But as Brazil has proven E85 can be done very well. Its real, its here and its just about got its teeth sunk in. The oil companies are trying to make move without breaking the law(Price Fixing and other illegal activities) they are buying E85 production facilities but they are being watched too. I think by ten years form now 1 E85 be be at every station just like Desiel is now and then its game over for the most part. There will never be the midlle east led price fixing, they'll have to battle and farmers will find massive scale to reduce prices to below oil and so on and so on, it'll be beautiful at this point I'm 95% sure it will happen as E85 has its foot in the doorway and in Brazil it went like clockwork and grew every single year till it was their dominant fuel.

Check here to find a station near you just as proof of how its out there.
