Default Re: A study says that ethanol is worse than gasoline for the environment
Here is a very good ( and colorful ) chart:
http://www.ncga.com/public_policy/PD...hanolStudy.pdf

Basically, it states it takes 1.23 btu of fossil fuel to deliver 1.00 btu of gasoline to the pump.

Conversely, it states it takes 0.74 btu of fossil fuel to deliver 1.00 btu of ethanol to the pump.

So this is a 3.7 to 5 ratio, strictly speaking about btu.
Since gas has more BTU per gallon, essentially 3 gallons of gas produces 5 gallons of ethanol.

.

Gasabout $0.05/mi
Gasabout $0.09/mi
E85about $0.09/mi
PHEV $0.0219 / mile*
*plus electricity, sometimes free! ( work / hotel lot )
