Distinguish the differences between the advantages and disadvantages of biomass.
Biomass Energy Advantages and 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
