Ideal for CBSE and other board students, this resource will simplify your study experience.Energy from various sources is considered to have been derived from the sun. Do you agree? Justify your answer.
Yes, I agreed to the statement that energy from various sources have been considered to have been derived from the sum, the reasons are as follows:-
In the wave energy, strong winds are generated due to the sun and the wave energy is generated by the waves that are generated by the strong winds blowing across the sea. In the Ocean thermal energy, Water at the surface of the sea is heated by sunlight but the deeper water is cold in the sea. This energy is obtained from the temperature difference which is due to the sunlight. Warm surface of the water is used to boil the volatile liquid and then these vapours of liquid like ammonia. These vapours are then used to run the turbine of the generator. In solar energy, the phenomenon of photoelectric effect (electricity production by the light) is possible only in the presence of the sun.
Energy from the fossil fuels are obtained by a lot of pressure and heat because they are buried deep inside the earth’s crust which are made by the dead organic matter. Energy can also be obtained from the water of seas, rivers etc. the water gets evaporated and falls at different places as snow or rainfall. And then this water gets collected in the large dams which allow it to flow after getting filled and then this water is used to rotate the turbines to generate electricity.
