Topic: Science and Technology
Q4. Examine the viability of nuclear fusion energy as a prominent clean-energy source in the coming years. (250 words)
Difficulty level: Moderate
Reference: India Today
Why the Question?
The world’s largest nuclear fusion reactor that mimics the Sun just came online in Japan
Key Demand of the question:
To examine whether nuclear fusion energy can replace fossil fuels.
Directive word:
Examine – When asked to ‘Examine’, we must investigate the topic (content words) in detail, inspect it, investigate it and establish the key facts and issues related to the topic in question. While doing so we should explain why these facts and issues are important and their implications.
Structure of the answer:
Introduction:
Begin by defining nuclear fusion.
Body:
First, write about the process of nuclear fusion in brief.
Next, mention the huge potential for growth, emission-free nature and consistent nature of nuclear energy production in contrast with wind and solar energy.
Next, write about the limitations of the above – technological constraints, lack of expertise, land requirement, manpower, financing etc.
Briefly mention the major developments happening in the field of nuclear fusion (including in India).
Conclusion:
Conclude with the argument that India should expand its sources of energy away from fossil fuels, to maintain its development while not harming the environment. Nuclear fusion gives a huge hope in this endeavour.
