Yes, I know what an SUV is. I am wondering how you concluded that SUVs are responsible for the push for ethanol.
People forget that energy is energy and its not free (from a physics perspective). Yes, electric cars don't emit at the tailpipe. They emit at the powerplant. Of course, the dynamos at the powerplant are a lot more efficient than the typical gas engine, but there is still a significant net CO2 emmision involved because those powerplants are usually running on things like coal and oil. Now, if nuclear power were more widely used we could have electric cars with virtually no CO2 emmisions, but we would have to find appropriate methods of disposing/storing the nuclear waste. The thing to keep in mind with electric cars is that the energy storage devices like batteries can have a very serious environmental impact that needs to be adequately addressed before the electric vehicles can be considered a truly viable option.
Biofuels (and other alternative fuels) do not necessarily have to drive food prices up. Like I mentioned, extra soybeans can be planted on fallow fields and algae-based biodiesel can be produced on non-arable land. This minimizes or eliminates the impact on food prices.
