Oh, goodness, thought we were past this at least. If you don't like ethanol fine, but at least there is ample science and work out there to be past this part by now.
Many good sources out there, Wikipedia is not always a perfect source, but if you start there they show the 1.3% return on ethanol in the USA that is the common, well researched, result I thought everyone knew about by now.
Read the abstract for the core info you all are asking for, you can download the whole report and read the whole dry paper for free.
There are many other sources out there.
There was one study, by a Big Oil guy, that factored in the sunlight as a cost in some slight of hand way, and also took the ddgs high protein, high mineral feed we get left from ethanol and just hauled it to a landfill I guess, and his one study, which has been discredited over and over and over as pure bunk, is likely what you are basing your ideas off of.
To each their own, but wrong is wrong.
Lot of research and science points to positive energy gain from:
Corn ethanol in the USA 130% efficient or so. Milk production in the USA 110% efficient or so. Certain types of beef production in the USA, tho not all feeding systems - quite varriable depending on how you value non- productive grasslands.
Farming is one of the few bright spots on efficiency in the USA, I'm just always plumb surprised folks on a more rural, more country oriented site like this are so totally anti-farm and need to stretch things to be so.
And now, as I often say, corn ethanol is -not- the solution to all the worlds energy problems, it is but a small player, offers us perhaps a 3% increase in transportation fuel is all. Evern with cellulosic added in down the road, wont get to be more than 6- 10% energy increase.It will never ever replace all fuel. But it is surprising how much extra jingle we all get to keep in our pockets with just that small 3% gain over the last 5-10 years.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
