Bioethanol: Problem or Solution

Very interesting presentation...does a great job of illustrating the law of unintended consequences. It's unfortunate that something that has so much promise to help mitigate one problem can cause so many others. Is there a way to harvest the "food" part of agricultural products to feed the population, and use the rest to produce biofuel?

I think that the use of biofuels is another short-term solution to our problem of using fossil fuels. Unfortunately, you run into deforestation issues and the slaughtering of the tropical rainforests in order to grow crops. I enjoyed the presentation.

good presentation. another of those misnomers from the world of energy to our doorstep. Biofuels, yes have plenty of upside, but does it combat there downside. Not if it is destroying more land, which in turn leads to more global warming. Plus right now most is being converted into fuel in places where coal is being used to make electricity for the fuel process, thus it is still using a lot of fossil fuel to make ethanol. Should we really be using land for food, as land for fuel? thanks for the presentation.

I enjoyed your presentation. My presentation also mentioned the cons of ethanol, in that bioethanol leads to eutrophication and hypoxia.

So to produce bioethanol, land would have to be seemingly destroyed and the grain/goods used to make the fuel could feed many people and animals. Sounds like a bad idea, but the fuel would reduce pollution. I would hate to be the one to make the decision to go ahead with production or not. Very interesting information. Good job!

This was an interesting presentation especially the information on the costs of bioethanol. It makes you wonder if this process is even worth it.

Very good presentation. I didn't realize that so much water would be required per gallon of bioethanol - but when you think about having to grow the grains it makes sense. I would hate for a person to starve due to us using the crops to make fuel. There are many cons to this issue that I have never even thought about. Thanks for bringing them to my attention.
