Following are the two sources of energy that are renewable:
(i) Wind: Wind energy is obtained from the air which is blowing at a high speed. Wind energy is trapped using windmills to generate electricity. Blowing of air is dependent on uneven heating of the earth. Since the heating of the earth is forever, wind availability will also be forever.
(ii) Sun: The energy obtained from the sun is known as solar energy. It is produced by the fusion of hydrogen into helium, fusion of helium into other heavy metals, and it continues. A large amount of hydrogen and helium is available in the sun, which will never be exhausted. Hence, solar energy is a renewable source of energy
