Ethanol - bad for the OVERALL Environment

"Several factors are in play including the amount of energy required for fertilizers, equipment and the amount of fuel required to drive a car (a tank of ethanol has less energy content than gas, MIT confirmed.) " From a news article.
During the winter months in Portland you get to have 10% (by volume) of your fuel ethanol - and if you see your gas mileage go down during this time this is why - usually 2 to 3 MPG lower than regular full strength 87 octane gasoline (petrol for you British folks).
Doing a quick calculation, what this means that out of 11 gallons of fuel during the winter the distance you drive is equal to 10 gallons used during the summer when NO ethanol is used. Thus you waste a gallon of fuel - 30 miles - and cause MORE pollution than without the ethanol mixed in.
Add in the amount of energy required to CREATE the ethanol that means overall it is causing MORE pollution than it is clearing up - just that the pollution is caused ELSEWHERE so the cities, like socialist leaning Portland, just shifted the problem to someone else's back yard.
Doing another quick calculation that means 24 gallons of fuel is "wasted" per car during the winter (8 refills), with 2 million cars in the Portland area that means 48 MILLION gallons of fuel, 120+ MILLION dollars spent by people filling up their tanks ($2.70 or so a gallon) - with NO benefit at all. Add in all the trucks used to transport that fuel around Portland itself (there is only 1 fuel delivery line serving Portland) and the waste goes on and on really costing around $200 million in "wasted" money due to their "Green" push to have ethanol in the fuel.
And the EPA and Portland (plus METRO) think they are HELPING us.
Well, they do, this brings to them around $28 MILLION dollars in gas taxes to them (state and local) in four months - which they spend on ????? 
Definitely NOT roads!
