[QUOTE="soberups, post: 344029, member: 14668"] That is because we are going about it the wrong way. Corn is a horribly inefficient way to make ethanol, but the corn lobby in Washington is quite powerful. Hemp and switchgrass are far better crops for this purpose, they use far less water, and they can be grown in rotation with other crops to avoid depleting the soil...but those crops dont have a congressional lobby. One thing to bear in mind however is that the majority of corn grown in this country is actually used for cattle feed. If you feed a cow raw corn it digests the starch and protien and farts out a huge amount of methane. If you take that same corn and refine it into ethanol, what you are left with are high-protien "distillers grains" that can still be fed to cattle....only instead of farting gas into the atmosphere, that same gas is being refined into ethanol prior to feeding. So when we criticize corn ethanol as a fuel we need to bear in mind that it can be made as a by-product of cattle food that is already being grown and is thereby getting two uses from the same crop.
