Journal: Alternative biofuel sources that aren't corn or soy

From a blog over at ZDNet about alternative fuels:

"A five-year federal study found that switchgrass can produce 540% more energy than it takes to farm it. Wow, that's very different from the heavily subsidized and fertilized corn crop now being used to produce ethanol biofuel. Corn produces only about 25% more energy and even soy-based biodiesel is less than 100% more energy productive. Switchgrass could also be used to produce ethanol. That would reduce greenhosue emissions compared to current gasoline."

It would be great to see the government invest more in developing such alternative sources.
