NY Times Looks at E85 Ethanol

And it’s not especially pretty. Among other things, it only has 75% of the energy density of gasoline, so you get 3/4 the mpg.

Which illustrates one of the big challenges of peak oil. There are few energy sources as cheap or convenient as petroleum-based fuels.

I won’t even get into the agricultural and environment issues around mono-culture corn production (yes, I know ethanol can come from other crops, but this was a corn-belt-focused story).
