For the planet earth, the Sun is the primary source of all energy.
The Sun is the most vital, abundant and direct source of energy.
India lies in the tropical zone and has plenty of sun shine, for long hours of a day.
There are large possibilities to develop solar energy in the country and that too without much cost.
Solar energy is tapped through the system of Solar Photo Voltaic (SPV) cells.
The thermal heating system can be used for water heating, solar cookers for cooking meals and drying food grains etc.
Solar energy can be developed in almost every part of the country but more so in hot, dry and cloud free areas like Rajasthan.
