The most exhaustive study on ethanols EROEI, by Isaias de Carvalho Macedo, shows an alcohol energy return of more than eight units of output for every unit of input—and this study accounts for everything right down to smelting the ore to make the steel for tractors.
This is BS. They start off discrediting Biofuel, then talk about corn ethanol. Yes, corn ethanol is probably not very efficient but Cellulosic biofuels are now being developed from landfill waste, any bio-waste or any plant waste. These materials are going to emit CO2 anyway as they decompose, we might as well harvest the energy for fuel.
Yes, more evidence that corn-based ethanol was merely a transition to more sustainable sources. Thankfully, though, we now have the actual processing plants built to take advantage of algae-sourced cellulosic material for ethanol production as a result.
No longer true. They have advanced ways to get ethonal from waste parts of plants.
The sugar in cellulosic biomass is locked up in cellulose, which contains normal C6 sugar, and hemicellulose, which contains Xylose (C5) sugar. Since normal yeast can't ferment Xylose, Celunol has acquired genetically engineered E. coli bacteria which can turn almost all of it into ethanol.
Biofuels are the way forward e.g they increase auto mobile performance and they are CLEAN. Also why doesn't the us govenment use bio-diesel machines to collect the corn instead of a fossil fuel. Because if you use a fossil fuel to get a biofuel you basically cancel out the clean non-polluting biofuels use by producing carbon dioxide to get a biofuel e.g ethanol.
This was supposed to be a telephone press conference and I showed up with a camera. A camera introduces a different element to the atmosphere and most groups just disallow the camera. Whatever the disruption my camera caused, they still impart much information. I also learned alot from following up on greyflcns comment in this thread about the california legislature/biofuels

@mikehanoo33 Where does the stated 1:8 input:output energy actually come from? What are the sourcing effects?

This is great no nonsense information. Thanks for posting. I wish they had talked more about non-corn biofuels as well, and how they compare.

How sad very few views of this and its so on the money.

This was touched on slightly in the California legistlature biofuels report.

Heh, well it's Friday.
Also wow, new study out today by the nobel prize winner who gave us all the ozone theory stuff.
It basically says that just by only the DIRECT emissions of biofuels, it's a horrible idea.
Since virtually all biofuel studies heavily discount N2O laughing gas, which is 296x more potent than CO2.

Where can I get the unpassworded version of the report.
All I can find is the press release copy.
