💡 Exam Tips for Energy Resources

🎯 How to Write a Good Comparison Answer

Always give a named advantage AND a named disadvantage for each source
Use comparatives: "Nuclear is more reliable than wind because..." not just "Nuclear is reliable"
For 6-mark questions, address all specified criteria (e.g. reliability, cost, environment)
End with a justified conclusion: "Overall, [source] is better for [country] because..."

📝 Key Command Words in This Topic

Evaluate — don't just list pros and cons; compare and make a judgement
Suggest — there may be more than one acceptable answer; give a reason
Justify — give a reason for your choice or recommendation
Discuss — explore different aspects; can include advantages, disadvantages, and context

⚠️ Common Mistakes to Avoid

Saying wind/solar is "free" — the fuel is free but equipment has high manufacturing and maintenance costs
Saying nuclear "produces radiation" as if this is unusual — all energy sources have byproducts; the question is whether they are manageable
Forgetting that biofuels do release CO₂ when burned (even if roughly carbon neutral)
Confusing "renewable" with "reliable" — they are different properties
Not specifying the context in evaluation questions — the best choice depends on the country's geography, resources, and priorities
