Switchgrass Makes Better Ethanol Than Corn

statemachine writes to mention that the USDA and farmers took part in a 5-year study of switchgrass, a grass native to North America. The study found that switchgrass ethanol can deliver around 540 percent of the energy used to produce it, as opposed to corn ethanol which can only yield around 24 percent. "But even a native prairie grass needs a helping hand from scientists and farmers to deliver the yields necessary to help ethanol become a viable alternative to petroleum-derived gasoline, Vogel argues. 'To really maximize their yield potential, you need to provide nitrogen fertilization,' he says, as well as improved breeding techniques and genetic strains. 'Low input systems are just not going to be able to get the energy per acre needed to provide feed, fuel and fiber.'"

    "The polling firm found that switchgrass ethanol can deliver only 0.54% of the voter cast in the states capable of producing it, as opposed to corn ethanol which can yield around 24% of the votes cast in the states that produce it."

    It's not about EROEI (Energy Return On Energy Investment), it's about PEOPI (Politicians Elected On Pork Invested).

    Switchfoot makes better music than Korn, too, but such opinion is no more revolutionary than the one in the article. Ethanol IS NOT the cure for our energy disease.

    I know the accurate scheduling and execution of many of my Linux system processes has benefited greatly from the strong United States cron lobby!
