How can we tell the Renewable Fuels Standard (RFS) is working? By how nervous it's making the big oil companies!

Ethanol is made in America, better for the environment, and good for your car, and above else, can help break you free from the grip you are currently under by the petroleum industry.

It's great knowing you have reduced your pollution by over half with every mile driven on E-85!

Hi Hannie,

That's what I thought. You took one piece and extended it. So the 50% is particulate matter from a non-catalytic vehicle output. Most cats will reduce that by 80%. So the gas vs ethanol margin is very slim. The CO does come out right so that's good news.

And I think the writer didn't get all the facts and stats right. The rest of the life cycle figures are going to be skewed from oil since it is carbon based and the assumption is all the oil is available naturally. So why do we drill miles down to get it out of the ground?

And 100% reduction is a zero emission? I think that calculation goes with the idea of plug-in EV as zero emission vehicles too. So where did the power come from in the first place? Cold Fusion?

agronomic alert; cold soil condition effect on corn;
http://trelay.com/uploads/AgSpotlight-ColdSaturatedSoilEffectsCornGermEmerge.pdf

The cold weather and cold soil conditions are holding off the planting.
Only a couple of week left to get those seeds in the ground.
Not a dependable way to base our energy supply .If they don't get the corn in the ground, the average will be dedicated to soy beans.

Not only when you run it in your car tdoiler, but the lifecycle analysis for ethanol is very favorable, EVEN FROM CORN. What I said was reducing your pollution, not one type of pollution over another. Studies, even on corn ethanol show that a driver's choice of E-85 over E-0 reduces total pollution over 50%.

From WIRED MAgazine, 2011

Myth No. 3: Ethanol crops and production emit more greenhouse gases than gasoline.

False. A 1996 EPA study analyzing sources of air pollution confirmed that gasoline vehicles and non-road equipment are the largest contributors to vehicular gaseous hazardous air pollutants. However, another study showed ethanol reduces tailpipe carbon monoxide as much as 30 percent and tailpipe particulate matter emissions by 50 percent (.pdf). And blending ethanol with gasoline dramatically reduces carbon monoxide tailpipe emissions and tailpipe emissions of volatile organic compounds that form ozone.

Finally, a life cycle analysis of ethanol found “at present and in the near future, using corn ethanol reduces greenhouse gas emission by more than 20 percent, relative to those of petroleum gasoline.” Blending cellulosic ethanol with gasoline to make E85 brings the reduction to 63 percent. Some purpose-grown woody crops for next-generation fuels actually increase soil carbon enough to yield over a 100 percent reduction in GHG emissions.

I will repeat:
Hannie, where did you get your info on "..reduced your pollution by over half with every mile driven on E-85!"

If it was economical then other countries would be exporting ethanol to the US. Cheaper labor, more land available, and can easily use other bio forms to get better yield more cheaply

I do not think it is "working" when it is not self supporrtive. The governement thows alot of money to keep it going.
