  The prickly pear has a number of advantages over other biofuel crops, such as wheat, sugarcane, and soybeans. For one thing, only the husk of the cactus is used for generating biofuel, while its inner flesh is still preserved for food. Therefore, using the plant as a fuel source will not put pressure on food prices.
