For those who didn't know, corn isn't the only thing that ethanol can be made from. There are many choices, including sugar beets, sugar cane, cull potatoes, and switch grass for example. That's right, I said switch grass.
"The research — reported Monday by the National Academy of Sciences — is the most extensive ever conducted on the potential to grow switch grass for energy. The report offers a positive outlook for cellulosic biofuels.
The study indicates an energy gain of 540 percent when processing switch grass into ethanol, compared to 130 percent to 140 percent for corn.
The energy calculations take into account all products used in production, including fertilizer and diesel fuel.
Switch grass is a tall, warm-season pasture grass that can be cut for hay. When grown for fuel production, producers allow it to reach flowering stage and cut it only once a year.
The study also found that greenhouse gas emissions from ethanol made with switch grass were 94 percent lower than emissions from gasoline production."
