Miscanthus biofuel field. Miscanthus x giganteus grass being grown for use as an energy source. Miscanthus (sometimes called elephant grass or E- grass) can either be burnt directly in electricity-generating power stations, or can be used to produce ethanol for fuel use. It is a promising crop for this purpose as it is low maintenance, has a low moisture and mineral content and provides a high yield each year. As a biofuel, it is renewable and is essentially carbon neutral, as the carbon it releases during combustion was taken from the atmosphere during its growth. Photographed in autumn at a farm in Charlbury, Oxfordshire, UK.
