Problems with ethanol - the fraud of alternative fuels
Published on April 26, 2007 By Draginol In Politics

In the past year or so we've seen more and more people jump onto the Ethanol bandwagon.  After learning more about it (and it doesn't take very long to do some basic research) I've concluded that Ethanol advocates are idiots.  Let me be very clear: If you think Ethanol is a serious alternative fuel you either haven't researched it at all or you are too dumb to be expressing opinions.

It's actually difficult to find a "plus" to Ethanol.  I guess, in theory, it would reduce dependence on foreign oil. Which seems ironic that anyone would tolerate the negatives to deal a minor blow to middle east oil producers even as they shop at Walmart (which imports vast amounts of its "stuff" from China) on their way to a "Get our troops out of there" protest rally.

So what's wrong with Ethanol? Let's count the ways:

1) It's not carbon-neutral. Not by a long shot.  Burning a bio fuel in itself is "carbon-neutral" but producing the bio fuel in the first place (whether it be corn or switch grass) and then harvesting it and then turning it into fuel is hardly carbon-neutral.

2) It takes more than 1 gallon of fresh water to produce 1 gallon of Ethanol. Think about that for a moment.  Environmentalists talk a great deal about conserving water. But producing Ethanol is one of the worst things you can do in that area.  When someone runs their shower for a long time, at least that water is (ahem) recycled if you're living in a city.  But the fresh water used for farming and producing ethanol is not coming back to the water table or the lake or stream it came from any time soon.

3) It pollutes the air. In our rush to worry about CO2 (better known as the stuff that plants breath) people seem to forget about good old fashioned real pollution

But let's put away the extra pollution in Ethanol itself, let's consider the production of it which involves using massive amounts of nitrogen for fertizing it and the effect of that.  Or how about all the other things involved in raising crops.  I'm no farmer but one doesn't need to look hard to find out that the "agribusiness" is a pretty environmentally intrusive thing.  It's one thing if it's being done for food, but as an alternative to gasoline?

4) It wouldn't even come close to solving our problems. Even if we turned nearly all the ariable farm in the United States to switch grass or corn production and we switched to using corn stalks or other more efficient methods of getting bio-fuels, we still wouldn't have enough for even today's gasoline needs. 

5) Ethanol actually requires more energy to produce than it provides.  Let me be clear on this because Ethanol advocates try to side-step this by saying that all energy sources are like this.  But the difference is that Ethanol already uses more energy in the sense that it takes more gas, coal, ethanol, whatever fuels you want to use to produce ethanol than the produced ethanol will provide back.

It's a fraud.  Really wanting something to be true really badly doesn't make it true. One study showed that a gallon of Ethanol has 76k BTUs but requires 116k BTUs to produce -- before you even start transporting the stuff! In other words, it's not a close call on that point.

It's like the Simpsons episode where Homer goes into the Grease business and Bart says "That bacon you just used to produce that grease that made 50 cents cost $5." and Homer says "That's your mother's money" and Bart says "But her money comes from you." and Homer says "And my money comes from grease."

THAT's the kind of reasoning an Ethanol advocate has to use. Homer Simpson logic.

6) Ethanol has less energy in the final fuel. That means you get fewer miles per gallon on your car which means more trips to the gas station and more overall overhead.

7) Ethanol production would (obviously) raise food prices.  The government subsidizes Ethanol production. So farmers produce it instead of other grops (you know, food). Food prices go up. There have already been food riots on this.  To dumb this down so that ethanol advocates can understand: We are paying taxes so that we can pay more money for our food.

8) How do you transport Ethanol? Do advocates realize that Ethanol is a type of alcohol? (the name implies it, no?).  That means you can't use pipelines like we do for gasoline. What happens to alcohol when you mix it with water? What happens to piping if you run alcohol through it for awhile? The wikipedia page for Ethanol talks about this. But it's easy to forget that its advocates apparently don't like reading..or math.   So even if we were willing to lay waste to the land necessary to produce this stuff, how do you transport it around? By truck or train. And what powers those? Grease?

None of these facts are hard to find out. They're not part of some conspiracy by the evil oil companies.  Half of it is common sense.  Fossil Fuels, whether we like them or not, are about the closest thing we have to Energon cubes we got.

We need to get away from fossil fuels but we need to do it intelligently. Ethanol is just such a patently stupid idea on so many levels that I can't believe no one has bothered to expose it yet and discredit it once and for all.

Personally, I think plug-in hybrids are a good start. Sure, our power comes from fossil fuels but it's lot easier (and cheaper) to control what power plants emit than cars. Moreover, the US is the OPEC of coal which is what most of our power plants produce.  Better yet, use nuclear power and send the waste over to Iraq (just kidding) (not kidding, secret evil plan in progress) .

Most of our fossil fuel use and CO2 emissions come from vehicles. Give me a car that could even go 20 miles per day on electric and I'd be off of gasoline.  The answer isn't to find some new magical carbon fuel, the answer is to reduce how much our cars use IMO.

Great article, Brad, you've done your homework on this one. Agree 100%.
on Apr 26, 2007
Thanks for the article. I haven't myself researched too heavily into the use of ethanol as a fuel source, but I'm glad that you posted this anyways as I learned quite a bit.

Comment number 3 is confusing though. I'm not sure exactly how ozone is actually released from the combustion of ethanol fuel. Most of the articles I've found relating to it says that it does so, but it doesn't tell me how exactly. I don't doubt it's true, but still would like to know how. I'll look into it some more.

Comment 5 is certainly interesting, I didn't know that. But is this something that could be fixed with better processing methods? In any case, it would show that it's certainly not viable in this stage, and resources used to making it production more efficient could be used on something more promising.

8) Yeah, I forgot about the polarity of ethanol. I can see many problems arising with ethanol that is too diluted.

I do agree with your final point. Increasing efficiency is probably the best thing we could do right now. So much energy is lost as heat, and in braking, it's incredible. If waste is reduced then we can certainly curtail many of the environmental and economic impacts. However, the fact that they are essentially non-renewable is concerning and an alternative will have to be found, but alas, it's not my area of expertise.

It still produces CO2...any hydrocarbon produces CO2 as a product when burned. Ethanol is drinking alcohol...with a formula of C2H5OH. The reaction of oxidizing it(burning it) is: 2C2H5OH + 7O2 ----> 4CO2 + 6H2O...so that's plenty of CO2 emission...

I agree it’s not a viable alternative to fossil fuels. Hell Bush likes it so that ought to tell you right there it’s a stupid idea. Hemp is actually far superior to corn or switch grass. It doesn’t need pesticides and very little fertilizer. It also has a number of other environment saving uses such as clothing and paper that would make it an environmental positive imo.

I also agree we need about 40 new modern nuclear power plants in this country. And if the government wants to subsidize something they can pay for 70% of this car for me and anyone else who wants one. Link

Yes, but the reason they call it "carbon-neutral" is because the CO2 that is released was gathered from the air in the first place, and so the net CO2 emissions are near zero.

It's like solar panels... the ideas are good. They have great potential... they just aren't ready for consumer use yet. Some day, ethanol, or something like it, might be a great fuel, but it isn't ready yet. It needs a LOT more research before it, or something similar, will be ready for use.

Excellent article.  I've put up news in this area quite a bit myself lately, pointing out a lot of the issues you've raised.

People are rushing to biofuels, especially Ethanol, and proclaiming these biofuels as the savior of the energy using world.  Your article lists mosts of the reasons why those people should slow down and think more before they start heading us all down the wrong path for our energy needs.

The problem with coal is that it does suck to burn, and the greens are trying to ban that just as hard as they are trying to ban Oil.  That is the real problem with Electric cars now.  They are not really carbon neutral as the energy created to charge the battery comes overwhelmingly from Oil and Coal - which the Greens are trying to ban.  There is not enough wind, water and sun to fulfill all the power needs of this country, and the only thing worse than oil and coal to a green is Nuclear power (which when handled properly is the best solution logically - but you will never get Nader to agree).

You briefly touched on the only reason that Ethanol is so popular.  It reduces dependance on foreign oil.

on Apr 27, 2007
Lets look at your arguments:

1) I consider this a strawman's argument. The fuel in itself IS carbon-neutral. I doubt there is anything in the production cycle which requires additional CO2 output. Besides, other fuels have the similar additonal production and distribution polution, so it doesn't worsen the situation.

2) So you produce in neightbourhoods where water is not a problem, or find some variants which can be cultivated on sea. You can't grow the crops everywhere, but that is hardly an argument against ethanol in itself. It just limits it usability somewhat and will heighten the price.

3) So do several variants of fossil gasolines. True, you have to look careful at this, but that article you found presented a worst case scenario. Given enough research I doubt the health risks will be severe.

4) now, this is what I call a valid point.

5) not really convinced on this point as the problem with energy is often the conversion from one type into another, and the transport. I don't care if ethanol would cost a massive amount of energy, if that is free energy. So, if you are using gas-based energy centrales to produce ethanol, you are right, but if you are using hydro-power or solar energy, you are not. So the Ethanal-advocates are right in their defense. (Of course there is also the issue that the energy used to produce ethanol could be used for something more useful, like hybrid-cars , hence my reference to 'free' energy).

6) So basically your point here is that you will need a bigger tank in your car?! Hardly an argument. Around here we have cars running on gaz, imagine the fuel tanks you'll need for that It only means that ethanol has some drawbacks, not that it is not a valid alternative.

7) basically the same argument as 2. You need to grow it. Which is great if you're producing far more food than needed, and a bit of a problem if you don't.

8) Don't confuse the end product ethanol with the raw oil which is going through the pipelines. Don't know about the US, but around here the gazoline I put in my car is not going through pipes, it is being distributed by cars, trains and boats. And my guess is you transport the ethanol the same way.

If you just look on the internet for arguments against something, you will find them, no doubt. And yes, you are right if you say that right now Ethanol is not a valid alternative yet. And yes, you are right if you claim that ethanol is no silveren bullet. It has issues. But it is a renewable fuel source, thait is what makes it green! And as oil definitely is not a renewable fuel source. Furthermore you can transfer to it gradually with relatively small investments, which makes it so attractive.

So ethanol is definately green, but whether it is also feasible, I don't know. Most of your points just require more environment friendly production methods and more technological research into possible solutions. I know that technological research sounds a bit cheap, but if you look at the polution of a car nowadays compared to the polution of a car thirty years ago, there is a huge improvement. Similarly a lot of the arguments against ethanol just boil down to that its production and use is not mature enough yet. Given enough incentives (like government regulations) those issues will be tackled.

The only issue I'm really concerned about is the farming part. We might indeed push people into starvation because the land is used for ethanol instead of food. My guess is we can't miss that much fertile land for ethanol, but that is just a hunch.

So believe it or not, I agree with your end conclusion that we need to get away from fosil fuels intelligently and that hybrid cars might very well be a better solution. I just don't agree with you that Ethanol advocates are just idiots (although some of them undoubtfully are ).

CORN ethanol , at least as technology currently stands, is next to a waste of time in the respect that politicians are pushing it to be the next wonder fuel. all the points you make are certainly valid on that. what brazil has done isn't about corn ethanol but sugar ethanol, which is much cheaper and efficient in it's production and conversion. unfortunately, our farmers grow too much corn, not too much sugar.

our political powers that be are trying to push the corn thing as some sort of parallel to the sugar ethanol program that has made brazil virtually energy independent. it's not. it's just a bunch of politicians trying to drive more pork to their districts / states for a product, that , like you state, doesn't do what it is supposed to do as advertised. politicians are trying to kill 2 birds with 1 stone (help farmers, help energy independence) and seem to be willing to buy any hogwash that will justify pushing corn ethanol down our throats.

while i applaud america at least starting to try to break the oil addiction, corn probably won't be the answer. at least with the current technology.

Great article, again! I especially appreciated point #7 and the snarky nuclear power remarks. Why is it that even France has more nuclear power production than our much more technically capable country?

I live in SE Virginia, home of Smithfield Foods, one of the largest food manufacturers in the world. They are very concerned about ethanol, because it will drive up the cost of corn, which is the primary feed material for pork and a significant portion for beef. Of course, it will drive their costs up, but ultimately, who do you think will pay for that increase? We the consumer, of course! So it's not just 1st line food costs to you and me, it will drive up food costs for probably all meat and dairy based food products as well! Yeah, great idea, just to save a couple bucks on gas. And don't even get me started on our "reliance" on Mid-East oil. Please.

This is where your arguement falls apart. If it "takes" energy to make it. It "ain't" free. The energy to make it has to coome from somewhere.


Distillation
For the ethanol to be usable as a fuel, water must be removed. Most of the water is removed by distillation, but the purity is limited to 95-96% due to the formation of a low-boiling water-ethanol azeotrope. The 96% m/m (93% v/v) ethanol, 4% m/m (7% v/v) water mixture may be used as a fuel, and it's called hydrated ethyl alcohol fuel (álcool etílico hidratado combustível, or AEHC in Portuguese). In 2006/2007, an estimated 17 billion liters (4.5 billion gallons) of hydrated ethyl alcohol fuel will be produced, to be used in ethanol powered vehicles.[15]


What are you going to use to get the water out? Heat, and heat takes added energy. Then there's also the fermentaion process which requires more (MORE ENERGY)


[edit] Ethanol-based engines
Ethanol is most commonly used to power automobiles, though it may be used to power other vehicles, such as farm tractors and airplanes. Ethanol (E100) consumption in an engine is approximately 34% higher than that of gasoline (the energy per volume unit is 34% lower


Then there's this little mess too.

We (the US) for the most part can't grow sugar. It takes a special type of climate that we don't have. The "only" place it could be grown is Hawaii. And unless I'm mistaken that state ain't all that big.


Sugarcane cultivation requires a tropical or subtropical climate, with a minimum of 600 mm (24 in) of annual moisture. It is one of the most efficient photosynthesizers in the plant kingdom, able to convert up to 2 percent of incident solar energy into biomass[citation needed]. In prime growing regions, such as Hawaii, sugarcane can produce 20 kg for each square meter exposed to the sun
