Introduction:
The major source of energy is derived from fossil
fuels. Due to the limited availability or depletion of
these sources with time, balance between the demand
and supply of energy seems to be degrading in the
coming years. Moreover the fossil fuels are polluting
in nature. In order to maintain a balance between
demand and supply of energy, there is a need to
exploit renewable sources to the maximum limit
possible thereby providing a clean, eco-friendly
source of energy.
