Yea, but you get like 40% WORSE gas milage. It's worthless. It just drives up the price of food. And what do you think delivers it? DIESEL trucks, and it's also worse for the enviroment to make. Ethanol is worthless, worse than Carbon Credits.
OK
Though you meant $$ Yes the jury is still out on wether or not it is viable or not. It does produce more HP per gallon but yes less MPG.
We can also make Biodiesel from oilseeds but the same thing aplies there.
Ethanol in its pure form (before it is denatured) is just moon shine so it is valuable.
