You left out the reduced efficiency of ethanol compared to raw gasoline as well as its deleterious effects on engines, especially small engines.
/// actually, the reduced efficiency is included here:
MORE btus to make a gallon of ethanol, than it contains!
...but, you said it much more clearly. (probably i should look up the exact ratio. it’s shocking, like 1/3 less)
and, i did leave off the engine damage.
(which nation-wide, must be a HUGE cost. ...yet another serious unintended consequence of this insane program.)
