Energy from various sources is considered to have been derived from the sun. Do you agree? Justify your answer.
It is true that energy from various sources have been derived from the sun. Following are
explanations for this:
(a) Plants harness solar energy to make biomass. This biomass was converted into fossil fuels. So, energy in fossil fuels came from sun.
(b) Firewood and gobar gas have got energy from sun; as explained in previous point.
(c) Water cycle on earth happens because of heat from the sun. So, kinetic energy in water is because of sun.
(d) Waves and ocean currents are caused because of heating from the sun. So, different kinds of energy from ocean have sun in their root.
(e) The earth was made after a piece from the sun took shape of this planet. So, geothermal energy or energy from nuclear power plant have come from the sun.
