🎓 Higher Tier: Evaluating Energy Choices
At higher tier, you need to evaluate energy resource choices — not just list advantages and disadvantages, but weigh them up and justify a conclusion. Key factors to consider:
- Environmental impact: CO₂ emissions, pollution, habitat destruction, wildlife
- Reliability: Is it available on demand? Is it intermittent?
- Energy security: Does the country have domestic supplies, or depend on imports?
- Economic factors: Construction cost, running cost, jobs created
- Scale: How much power does it actually produce? (One nuclear station = hundreds of turbines)
- Social factors: Visual impact on communities, noise, public opposition
- Transition challenges: The existing grid was built for large, steady fossil fuel plants — intermittent renewables require significant upgrades to storage and transmission
A good evaluation will acknowledge trade-offs: wind is good for CO₂ but intermittent; nuclear is reliable and low-CO₂ but produces dangerous waste. The "best" choice depends on the priorities of the decision-maker and the specific context.
