Sun is the major source of energy. We utilize solar energy in different ways. It is renewable source of energy Plants prepare food by using sunlight. From these fossil fuels, firewood are formed. Windmills works by utilizing kinetic energy of wind energy from infrared rays. Tidal energy is obtained due to gravitation. When we consider any energy sources, they were originated from solar energy.
