Media coverage of the controversy surrounding the use of certain non-native feedstocks for bioenergy is as pervasive as invasiveness itself. Plants such as giant reed (Arundo donax) and elephant grass (Pennisetum purpureum) are known to be weedy or invasive in natural habitats; the concern lies in their ability to spread propagules into natural habitats outside intended areas.

Energy crop developer Ceres, Inc. reports that growers are ready and willing to produce biomass for biopower and advanced biofuels, and have the land to do so.

Corn cobs could provide a future energy source, but farmers would have to receive a much higher price than previously thought to cover their costs and turn a profit, according to a Purdue University study.

Giant miscanthus, which is a perennial warm-season grass from Asia, is garnering attention across the Midwest because of its high biomass output, its potential for conversion to ethanol and its adaptability to many different soil types.
