Compare and contrast bio-mass and hydroelectricity as sources of energy.


Biomass is the fuel developed from organic matter waste of living organisms like plant waste, animal waste, forest waste, and municipal wastes.

In biological terms, the word biomass refers to the organic plant matter, which is transformed into fuel and used as an energy source. Biomass fuel is considered to be of great importance as it plays the role of a renewable and sustainable source of energy. For example, biomass is used for the production of electricity. Due to this, biomass is capable of replacing fossil fuels.


Hydroelectricity refers to the generation of electrical power by the use of hydropower. Hydropower here principally is the gravitational force of falling water. It is the most extensively used form of renewable energy considering for 3% of the world’s total energy consumption. The cost of hydroelectricity is moderately low, giving it a competitive edge as a source of energy. The average cost of electricity for a large hydropower plant is very less. Energy production is dependent on the amount of water that is let out since this can be controlled, hydropower plants have the advantage of being flexible. The output can be controlled as required by the need.
