Question

Which of the following is more environment friendly?

• A. Fission reactor
• B. Fusion reactor
• C. Both are equally environment friendly
• D. Nothing can be decided

Answer 1

The correct option is B

Fusion reactor

Explanation of the correct option

B: Fusion reactor

1. We know that fusion is one of the most eco-friendly energy sources available. The fusion process produces no $c{o}_2$ or other hazardous atmospheric pollutants, implying that it has no impact on greenhouse gas emissions or global warming.
2. Fusion has two fuel sources, hydrogen and lithium, which are abundant in many parts of the world.
3. A controlled fusion of atoms produces about four million times the energy of a chemical process like coal, oil, or gas burning, and four times the energy of nuclear fission reactions (at equal mass).

Explanation of the incorrect option

A: Fission reactor

1. Nuclear fission is still the clean and most powerful energy source available to civilization but is less clean than fusion reaction.

C:Both are equally environment friendly

1. We all know that both fission and fusion reactors are not environmentally friendly.

Hence, option (B) is the correct answer.
