Renewable energy resources are of great interest today. Miscanthus research has been conducted at several locations including the University of Illinois, at Cornell University's grass bioenergy website and North Carolina State University have or are currently conducting research on miscanthus biomass. Farm Energy shows new analysis of miscanthus for biomass. Europe and England have also conducted research. Almost all of this work has involved Miscanthus x giganteus, a natural hybrid of Miscanthus sinensis and M. sacchariflorus, as the best biomass fuel or fiber source. Crosses with sugar cane and other grasses are being explored as a perennial biomass fuel source.
