Question

18 Solar light is allowed to fall on solar panel to generate electricity. It is not so common practice to generate electricity in this way. So it is known as non-conventional energy. Which one of the following is an example of non-conventional source of energy? (a) Mineral oil (b) Coal (c) Biogas (d) Wood​

Answer 1

Answer:

Bio gas

Explanation:

organic waste such as dead plant and animal material, animal dung, and Kitchen waste can be converted into a gaseous fuel called biogas. The organic waste is decomposed by bacteria in biogas digesters to emit biogas which is essentially a mixture of methane and carbon dioxide

Answer 2

C) Biogas is an example of a non-conventional source of energy. Non-conventional sources are also known as renewable sources of energy.

Explanation:

• Non-conventional sources of energy are considered to be important as they are renewable, pollution-free, their availability them is in abundance, and they are environmentally friendly.
• The largest non-conventional source of energy is solar energy.
• They are mainly used for household purposes. These are not responsible for the cause of pollution.
• Biogas is an environmentally-friendly, renewable energy source.
• It is produced when organic matter, such as food or animal wastes, is broken down by microorganisms in the absence of oxygen, in a process called anaerobic digestion.
