Tworenewable sources of energy are as follows:
(a) Sun: The energy derived from the Sun is knownas solar energy. Solar energy is produced by the fusion of hydrogeninto helium, fusion of helium into other heavy elements, and so on. Alarge amount of hydrogen and helium is present in the Sun. Therefore,solar energy can replenish on its own. The Sun has 5 billion yearsmore to burn. Hence, solar energy is a renewable source of energy.
(b) Wind: Wind energy isderived from air blowing with high speed. Wind energy is harnessed bywindmills in order to generate electricity. Air blows because ofuneven heating of the Earth. Since the heating of the Earth willcontinue forever, wind energy will also be available forever.
