This chapter discusses the alternate energies that are being developed from agriculture. It considers many advantages and disadvantages of these forms of energy. The main advantages of biomass fuels are that one type or another can be grown almost anywhere and unlike petroleum products, they are renewable and relatively non-polluting. Whilst most attention has been given to sugar cane (Saccharum officinarum) many other plant species are capable of producing alcohol or other fuels like oil and firewood. Yields are high because of its C4 photosynthetic pathway and large leaf area. One of the disadvantages of the crop is that harvesting costs are high because much labor is generally needed. However, these disadvantages are outweighed by the use of byproduct bagasse for processing energy and the easy and well established fermentation of molasses to ethanol. Cassava, a photosynthetically efficient and easily grown root crop is currently receiving much attention as a means of, expanding alcohol production into areas of Brazil that are considered too dry for sugar cane. Yields of alcohol per hectare are usually quoted as being below those of sugar cane when average yields of 12-15 ton/ha are used. The African oil palm (Elaeis guineensis) looks the most interesting crop from the point of view of yield. Many other new oil bearing crops are being studied at present and a few are thought to have interesting futures because of their high potential energy yields. |
