Related: About this forumUH-OH, secret document leaked: Ethanol gets about 7% less mpg than gas; 10% BETTER on energy equiv
basis. This is quite a bit different than the 35% mileage decrement so often quoted.
These are the results of a test of cars actually driven on the street, some using gasoline others using ethanol, over a two year period (not dynomometer tested) conducted by the Batelle Memorial Institute for the National Renewable Energy Lab - when was this done?...[font size="3"]in 1998![/font] (got this off a web site that indicated it was last update for content on Jan 30, 2012).

(37,540 posts)Good news, but I'm not convinced that ethanol is our best long term energy source for powering vehicles.

I'm pretty cautious about predicting for "the long term". I am worried enough about tomorrow. Oil has been flirting with $100 (West Texas, NOrth Sea Brent with $110 a barrel) thanks to 1) the Arab Spring and 2) Iran nuclear program. Experts are now saying once we get to Memorial day gas could easily be at $4.00 a gallon. If (When?) Israel strikes Iran's nuclear facilities I think $4.00 gas will quickly become a fond memory.
Gas at $4.00 a gallon will take a good deal out of our meagre recovery. If it goes above that (depending on how far) we could see zero growth and increased Unemployment. These developments for the long term do not bode well for developing and deploying other more technically advanced, and more expensive, technologies such as electric cars. NOT good.
I have said before that we should be increasing methanol production (from natural gas) to be added to ethanol to further reduce our need for petroleum fuel. Of course, we are not going to do that. At least not until we have petroleum prices strangling our economy. Then we might do it.
Unfortuitous developments in the short term will dramatically affect what we will be able to do in the long term ---- unless we take such actions that can produce short term changes in our dependency on petroleum. (note in addition to adding methanol to the ethanol supply we should have been promoting the development of the Ethanol Enabled Direct Injection engine designed by three MIT scientists, which gets 30% better fuel economy (comparable to conventional hybrids) for about one fourth the cost.
Ethanol Boosting Systems
These steps might have saved the economy from the coming petroleum cost contraction (or at least minimized the damage) which will put off deployment of electric cars even further (you have to have quite a few people who have enough free money to buy electric cars to expand their use.).

(37,540 posts)If ethanol as 10% better energy efficiency than gas, why does this translate to 7% less mpg? I want to moderate my original comment to agree that ethanol would certainly be a strategic optional source of fuel should petroleum futures escalate on geo-political events. I think there may be better longer terms options to the internal combustion engine, but it will take better battery storage technology and more investment in solar energy in general.

Converting corn to fuel ethanol damages the environment in many ways.
Nothing good comes from this kind of corn growing -- not factory farmed meat, not high fructose corn syrup, not ethanol fuel.
We've let other industries die, some that actually improved life in the U.S.A. with well paying U.S. jobs and some of the highest quality products in the world. Gone, so many of them replaced with lower quality, short-lived goods made in low-wage nations where workers suffer unspeakable abuses.
Growing mutant monster corn ought to be on a list of industries that need to die, right up there with mountaintop removal coal mining, uranium mining, and much of our corrupt-beyond-redemption "defense" industry.
You know what I'd like to see instead of ethanol? How about hemp clothing grown and made by union workers in the U.S.A.... How about electric cars powered by solar panels, all made in the USA by union workers... How about banning inhumane factory farms and raising our livestock in open places? How about we turn some of our corn fields back into wild prairie, with bison, wolves roaming free...
