It emits equal net carbon dioxide, but less carbon monoxide.Wiki wrote:
Compared with conventional unleaded gasoline, ethanol is a particulate-free burning fuel source that combusts cleanly with oxygen to form carbon dioxide and water. The Clean Air Act requires the addition of oxygenates to reduce carbon monoxide emissions in the United States. The additive MTBE is currently being phased out due to ground water contamination, hence ethanol becomes an attractive alternative additive.
Use of ethanol, produced from current (2006) methods, emits a similar net amount of carbon dioxide but less carbon monoxide than gasoline.[48] If all bioethanol-production energy came from non-fossil sources the use of bioethanol as a fuel would add no greenhouse gas.

In the US. It's great in places like south america where sugarcane is basically a weed they grows on its own.TheDarkRaven wrote:
I believe that it does 'release', as you say, the same amount of emissions. [EDIT] I meant in terms of CO2, which is all people seem to care about.
But the argument for ethanol use is that it is produced from plants which absorb CO2 for use in photosynthesis, thus making it a more viable fuel than normal 'gasoline'. However, the area required for arable production for the bio-ethanol fuel to replace 'gasoline' is so vast that it is impossible to use as a viable sole replacement.

C2H5OH
Ethanol is an organic substance (meaning it's composed primarily of carbon, along with hydrogen and oxygen.) whenever you combust an organic in air (O2) the byproduct is always CO2 and H2O.
Stoichiometrically the combustion of ethanol looks something like this:
C2H5OH + O2 --> CO2 + H2O
(then balanced)
1 C2H5OH + 3 O2 --> 2 CO2 + 3 H2O
So every 1 mole of ethanol (roughly 42.039 grams) will yield 2 moles (or about 28 grams) of CO2
True. Ethanol can be made from fermentation of glucose (the monomer of starch). The net result from the formation of glucose to the combustion of ethanol is a big fat zero increase in CO2.Phrozenbot wrote:
It's carbon neutral.
But only because the engines aren't designed for it. If the engine is designed for it, it works just fine.Spark wrote:
Not exactly great for one's engine though, so people are reluctant to contemplate it.

wtf is ethynol (chemically)?
Last weekend I had a rental car that was flex fuel. It took E-85 which I assume was ethanol. Amazing gas mileage and no drop in performance. Plus the gas was cheaper also. Me like.Bubbalo wrote:
