Question

Which one of the following is not ultimately derived from the Sun’s energy?
A. Fossil fuels
B. Wind energy
C. Geothermal energy
D. Biomass

Answer 1

Hint: Energy can be derived from many sources that’s why in the solution of this problem, we will be explaining the different types of sources of energy such as fossil fuels, wind energy, geothermal energy and biomass.

Complete Step by Step Answer:
Fossil fuels are the fuels which are obtained from the earth’s core and formed by the decomposition of organisms, plants, animals, etc. over a period of millions of years. These fuels are derived from the sun’s energy directly or indirectly.Wind Energy is a form of energy which is obtained by utilizing the energy of the heavy winds. In other words we can say that the energy of heavy winds is transferred to the wind tunnels as a result of which energy is produced.

Geothermal energy is a form of thermal energy of the earth crust. We can easily understand that this thermal energy is not related to the sun’s energy.Biomass is the form of energy which is produced by the decomposition of various waste products by utilizing their energy. The biomass materials could be corn, seeds, etc. This energy is also derived from the sun’s energy indirectly.From the above explanation, it can be clearly said that geothermal energy is not derived from the sun’s energy whereas fossil fuels, wind energy and biomass energy are directly or indirectly derived from the energy of the sun.

It can be said that from the given options, only geothermal energy is derived from the energy of the sun. Therefore, the option (C) is correct.

Note: Do not confuse with geothermal energy as the heat energy derived from the sun because geothermal energy is the thermal energy of the earth crust.
