The way Bio-Fuels are being approached in the United States is plain stupid! We're using corn kernels to make ethanol to fuel our cars, the kernels are only about 5% of the total plant. Using sugarcane like Brazil does makes much more sense since the entire plant is used. Brazil itself used very little sugarcane domestically so utilizing it to make fuel helped prices their domestic economy and raised export prices. Both of these were good for their economy. The United States uses much of its corn for animal feed or other products that are utilized domestically thus diverting corn for another use only hurts prices for their consumers. Soybeans use for Bio-Diesel is much the same especially in regards to only using a small portion of the plant. The fuels being approached like they are being in the United States only hurts our overall economy. Granted it's a benefit to a few small sectors but it's detrimental to the economy as a whole. We need to pursue other sources of energy that we have a large quantities (Coal and potentially Nuclear) as well as other renewable sources such as Solar, Hydro, Wind and Geothermal in order to ensure our economy remains strong.
