The sun is almost inexhaustible source of renewable energy. Solar energy generated by solar radiation on the earth is 15,000 times greater than the energy consumed by man on earth.Solar energy does not pollute and is also free. Thus the goal should be to use solar energy to the maximum extent. Besides the known examples of the utilization of solar energy for space heating water heating swimming pools and to generate electricity for lighting
solar energy can be applied in many ways including the following: ...
Production of electricity using solar photovoltaics
Production of hydrogen using a photoelectrochemical cell
Production of electricity using concentrated solar energy
Production of electricity by heating trapped air which rotates turbines in a solar tower
Heating of buildings, directly through the construction of passive solar buildings
Heating of food products using solar oven
Heat water or air for domestic hot water for space heat using solar thermal panels
Heating and cooling air through the use of solar fireplaces
Production of electricity in geosynchronous orbit using solar satellites
Solar air-conditioning units
