Switch Grass
Switch grass is one of the most efficient biofuels yet developed. It is a perennial crop, meaning that it grows all year long. Normally, swith grass grows on the prairies and can reach 2.2 meters tall. Through a refining process,switch grass turned into cellulosic ethnol which can be used in car engines. Some studies show that biofuels using switch grass produce 540 percent more energy than needed to grow,process and refine it. This is a very high "net energy yield," much better than corn ethanol. Currently, the technology used to covert switch grass into ethanol is not as advanced as that does not adversely affect food prices. Both of these biofuels are promising for the future
