Distinguish the differences between the advantages and disadvantages of biomass.


Biomass Energy Advantages and Disadvantages
Advantages
Disadvantages
  • Reduces need for fossil fuels for the production of heat, steam, and electricity for residential, industrial & agricultural use
  • Available almost everywhere
  • Biomass fuel from agriculture wastes may be a secondary product that adds value to agricultural crop
  • May reduce municipal, agricultural and industrial waste
  • Is an inexhaustible fuel source if harnessed properly
  • Growing "energy crops" puts idle farmland to use
  • Sulfur, nitrogen oxides, and carbon emissions can be significantly reduced by burning biomass
  • Carbon dioxide which is released when biomass fuel is burned, is taken in by plants
  • Agricultural wastes will not be available if the basic crop is no longer grown
  • Additional work is needed in areas such as harvesting methods
  • More expensive than conventional fossil fuels
  • A less concentrated form of energy, making it less efficient
  • Releases some emissions, especially if burned improperly
  • Some biomass conversion projects are from animal wastes and are relatively small and therefore are limited.
  • Research is needed to reduce the costs of production of biomass based fuels
