Question

Which one of the following forms of energy leads to the least environmental pollution in the process of its harnessing and utilization?

• A. Nuclear energy
• B. Thermal energy
• C. Solar energy
• D. Geothermal energy

Answer 1

The correct option is C

Solar energy

The explanation for the correct option:

In the case of option C,

1. Solar energy is any type of energy that is produced by the sun.
2. Solar energy can be directly or indirectly harnessed for human use.
3. Solar panels mounted on a rooftop harvest solar energy and convert it to electricity.
4. Whenever solar panels are utilized to generate electricity, no air or water pollution is produced. It does not necessitate the transportation of fuels or the disposal of waste products. Solar energy generates power softly, allowing it to be used in residential settings without causing noise pollution.

The explanation for incorrect options:

1. In the case of option A, metals such as uranium are used in nuclear energy, which emits harmful rays that can harm living organisms.
2. In the case of option B, coal is used in thermal energy, which emits sulfur and carbon dioxide, causing air pollution.
3. In the case of option C, the pressure is absorbed by the heat from the core, which can be extremely hot and dangerous at times.

Hence, Option(C) is the correct answer.
