Here is a link to a good article about of ethanol as a fuel. If you are looking for a sustainable, "green" fuel, ethanol is probably not what you think it is.

A quote:

"...the bottom line is that, broadly, to perform the same job as an equivalent volume of petrol, you’d need to burn about 40 per cent more pure ethanol, and it would emit the same (or very similar) amount of CO2. "

The article doesn't touch on the fact that the last time I checked, it still took about as much energy to convert raw plant matter into a burnable fuel as you can get from the end product burnable fuel. Which makes the whole excersize totally pointless. (Am I wrong about this?)

Also it doesn't touch on how mindblowingly awful ethanol fuel is on metal. (Your engine is made of metal.) I work in this industry. A conventional part of basic aluminum costs about a sixth of what it costs to make the same product able to stand up to 85% ethanol fuel. Its ugly stuff.

It's politicized science, unfortunately.
