GEOGRAPHY AND HISTORY

  Biomass refers to the total organic matter found on the earth’s surface in terms of plants and animals These plant/animal matter can be converted into energy by biological and thermochemical processes The main sources of biomass energy are agricultural wastes Animal waste such as cow dung and human waste is used to produce biogas a combustible gas generated by the fermentation of organic matter e.g. cow dung Biogas can be used as cooking gas and in refrigerators Advantages of biomass energy Inexhaustible as long as there is organic matter. Available throughout the world. Cheap because uses waste products. Production doesn’t require advanced technology Biogas gives twice as much heat as natural gas . Slurry left behind when biogas is being made can be used as fertilizer. Disadvantages of biomass energy Cannot be transported over longer distances. Contributes to global warming ( pollution ) if burnt directly. Requires large spaces for the construction of the bio-digesters  RE...
