Miscanthus for Ethanol
Having even more potential yield than either corn or switchgrass, Miscanthus is a perennial grass that can grow on marginal land, and if it is harvested at the correct time it requires little fertilizer. Researchers say that they can harvest 2.5 times as much ethanol per acre as they can get with corn.
"One of the criticisms of using any biomass as a biofuel source is it has been claimed that plants are not very efficient " about 0.1 percent efficiency of conversion of sunlight into biomass," Long said. "What we show here is on average Miscanthus is in fact about 1 percent efficient, so about 1 percent of sunlight ends up as biomass." ed.z.: More plants for the energy mix! Those numbers don't look bad.
