I know I’m late to this post, but I’ve just recently stumbled upon your blog. I urge you to do more research on ethanol. I know it’s not the only solution, but I do feel it can be a piece of the puzzle.

It doesn’t use the part of the grain that we/cattle eat. There is still a byproduct of Dried Distiller’s Grain to be fed to cattle.

Cornell’s research is reported to have included the energy that the farmer used driving his truck to town to get lunch, and the energy used to cook that lunch.

The thing is it’s a technology we have now, and it’s something to build off of. Perhaps switchgrass will be a better solution. But look at what Brazil has done by putting forth the effort to become energy independent! The have tripled their output of ethanol from one acre of sugar cane in 30 years.

You are correct, it will never meet all our fuel needs. But hopefully it can help be a part of it.
