What fuel to use?

So, i once learned from an episode of West Wing that ethanol uses more fossil fuels to make than it would to just use gas in our cars. Still, I thought that there had to be something to biodiesel and have fantasized for the past year about buying a 4runner and converting it to biodiesel. I really, really want an old body style 4runner, but I simply can't justify it. However, if I could make it run clean, wouldn't that be nifty?
Then I run across this article from Cornell University stating scientifically what Hollywood already told me -- bio fuels aren't efficient.
from the July 2005 study:

In terms of energy output compared with energy input for ethanol production, the study found that:

* corn requires 29 percent more fossil energy than the fuel produced;
* switch grass requires 45 percent more fossil energy than the fuel produced; and
* wood biomass requires 57 percent more fossil energy than the fuel produced.

In terms of energy output compared with the energy input for biodiesel production, the study found that:

* soybean plants requires 27 percent more fossil energy than the fuel produced, and
* sunflower plants requires 118 percent more fossil energy than the fuel produced.

So where do we go now? Electric cars? Hybrids?

Ideally, I would like to bike, walk, or take public transportation to work. However, I can't afford to live near my work for walking or biking, and Seattle's mass transit outside of main areas in the city are for shit. It would take me two hours each way to cover the distance it takes me 20 minutes to drive. Apparently, that is where my willingness to sacrifice for the Earth ends.

Also, what do we do about all the land being used for corn that is subsidized by the US government? Being from Ohio, I know the importance of farming, especially corn farming. However, we could be producing so many other things, couldn't we? Am I dreaming to think that we could dismantle the corporate farms and go back to the way things were, when small farmers could actually make a living? I need to read more on this.

For now, I guess I need to make little changes like walking to the store more often and unplugging stuff in my house when I'm not using said stuff.
