Prickly Pear cactus is drought-resistant, can be grown where other crops die, and makes surprisingly good fuel for anerobic digestion, which then creates biogas. The cactus breaks down much faster than manure and is considered a nuisance in many areas now. It can be harvested, perhaps on commercial scale, to produce natural gas or generate electricity.
