Name two energy sources that you would consider to be renewable. Give reasons for your choices.
Two
renewable sources of energy are as follows:
(a) Sun: The energy derived from the Sun is known
as solar energy. Solar energy is produced by the fusion of hydrogen
into helium, fusion of helium into other heavy elements, and so on. A
large amount of hydrogen and helium is present in the Sun. Therefore,
solar energy can replenish on its own. The Sun has 5 billion years
more to burn. Hence, solar energy is a renewable source of energy.
(b) Wind: Wind energy is
derived from air blowing with high speed. Wind energy is harnessed by
windmills in order to generate electricity. Air blows because of
uneven heating of the Earth. Since the heating of the Earth will
continue forever, wind energy will also be available forever.
