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.
|
So...you've never been to a farm you mean. Do you know what's involved in making corn and then distilling it and then transporting it?
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.
|
Well heck, let's use that logic to its final conclusion - let's just live in places where the results of pollution (or if you believe in human made global warming) won't be a big deal. What magical land did you have in mind for producing Ethanol then? The places I was referring to involve places where we grow things where the water is largely coming from the water table or a nearby lake or river.
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.

Compared to ethanol, gasoline is a "green" fuel when it comes to pollution. If we switched purely to ethanol, a lot more people would die from air pollution.
4) now, this is what I call a valid point.
|
It's the elephant in the room. It's not even a viable fuel because we can't even remotely produce enough of it.
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).
|
But the energy ISN'T free. That's like saying "Well if the energy is magical". Let's say we moved to a purely Ethanol based economy. Everything is Ethanol. If it takes MORE than 1 gallon of Ethanol to produce 1 gallon of Ethanol what is the result going to be?
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.
|
My point is that we would still end up putting MORE stuff in the air. You'd need a bigger tank which adds weight and uses resources. It means you get even fewer miles per gallon. To me, a "green" fuel is one that is..well green. As in, doesn't pollute as much as what it is supposed to replace.
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.
|
The difference here is the unintended consequences. My problem with so many environmentalists is that they're so into their own narcisism that they can't be bothered to THINK. They talk about wanting to help starving people in Africa and elsewhere even as they advocate policies that would make it worse. It's the whole "But we had good intentions" nonsense.
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.
|
No, there's a big difference here. I can assure you they are not transporting gasoline from the refinery to your local gas station in a truck or train. It's by pipe. But that's exactly what would happen with ethanol.
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 as long as we can keep doing it it's green? That's all it takes? Wow. None of the facts I presented were really disputed by you. You just don't seem to like me pointing them out.
So ethanol is definately green, but whether it is also feasible, I don't know.
|
To me, things that create more pollution than something termed non-green is not green in my book. Garbage incineration is "renewable" too. Is that a "green" technology too?
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
).

I believe Ethanol advocates are idiots in the same way that I think people who follow the Underpants gnomes philosophy on business are idiots.
A lot of the issues with Ethanol are not subject to technological innovation. If it takes 2 gallons of Ethanol to make 1 gallon of ethanol you really don't need to go much further than that. Or if the physical land area available for agriculture is less than is needed to produce it then there's not much more to discuss.
The arguments for Ethanol always go "Ethanol is good" <Insert magical technological innovation> "PROFIT!"
