Solar energy

Solar energy is one kind of energy in which solar radiation is used for production of energy. Among the various non-conventional source of energy solar energy seems to hold out the greatest promise the mankind. The solar energy is free, inexhaustible, nonpolluting and friendly for environment. The rapid depletion of fossil fuels and combined crisis of pollution and of steep rise in oil price have brought about an upsurge of interest in Solar energy. The existing source of energy such as coal, oil, water and uranium may not be sufficient to meet the increasing energy demands. This requires that scientists and engineers should undertake resources work which would help in exploring the possibilities of harnessing energy from several nonconventional source of energy.
