Bioethanol: Solution or Problem?

Opinions seem to be quite diverse about using bioethanol as a fuel.
So is bioethanol a solution or a problem?

My view is that it will not solve the CO2 emission problem. All it can do is to reduce dependence on fossile fuel, but that is a very temporary relief, which has more to do with politics.
It is quite likely that a massive production of bioethanol will have more negative consequences than positive ones.
Using agricultural land to feed our cars instead of meeting the increasing demand for food as the world population increases strongly rises questions, especially ethically ones. Of course, a way of coping with this would be to turn more land from its current use into agricultural land, but that probably will result in more environmental discussable practices such as excessive deforestation.
I would love to see a thorough and comprehensive study of all the consequences, positive as well as negative, to know where bioethanol might lead us. What will the impact be on gas emissions? What will be the impact on fuel costs? What will be the impact on agricultural and food prices? So far, I have only read opinions and I haven’t found such research.

As long as this stays this way, I will choose the principle of precaution and favor policies that encourage people to cut their energy use instead of getting massively and blindly in something that appears to me as an illusion.
