Real IELTS Sample Questions and Model Responses

Sample Question 1: Renewable Energy Transition Speed

Question: "Some experts argue that countries should transition to renewable energy as quickly as possible to combat climate change, while others believe a gradual transition is more practical and economically sensible. Discuss both views and give your opinion."

Model Response Structure:

Introduction: The urgency of climate change has intensified debates about renewable energy transition timing, with stakeholders advocating dramatically different approaches to clean energy deployment. While rapid transition proponents emphasize environmental imperatives and technological readiness, gradual transition advocates highlight economic stability and practical implementation challenges. This essay examines both perspectives before arguing that ambitious renewable energy targets combined with pragmatic implementation strategies offer the most effective path forward.

Body Paragraph 1 (Rapid Transition Perspective): Advocates for immediate renewable energy deployment present compelling evidence that technological capabilities and environmental urgency justify aggressive clean energy transitions. Current renewable energy costs have reached grid parity with fossil fuels in most global markets, with solar photovoltaic prices declining 89% since 2010 and wind costs dropping 70%, eliminating economic barriers to rapid deployment. Countries like Costa Rica and Iceland demonstrate rapid renewable transition feasibility, achieving 95% and 85% renewable electricity respectively through focused policy commitment and investment. Furthermore, climate scientists emphasize that limiting global warming to 1.5°C requires 45% emission reductions by 2030, making gradual transitions inadequate for avoiding catastrophic climate impacts that would impose far greater economic costs than transition investments.

Body Paragraph 2 (Gradual Transition Perspective): However, gradual transition advocates highlight legitimate practical and economic constraints that make immediate renewable deployment challenging and potentially counterproductive. Grid integration of high renewable percentages requires sophisticated infrastructure upgrades, energy storage systems, and demand management technologies that need time to develop and deploy effectively. Germany's rapid renewable expansion, while environmentally progressive, resulted in some of the world's highest electricity prices and grid instability issues, demonstrating transition speed trade-offs. Additionally, fossil fuel industries employ millions of workers globally whose livelihoods depend on managed transitions that provide retraining opportunities and economic alternatives, making sudden industry elimination socially disruptive and politically unsustainable in democratic societies.

Conclusion: While environmental urgency demands ambitious renewable energy targets and accelerated clean energy investment, I believe that successful transitions require balancing speed with implementation pragmatism. Countries like Denmark and Norway demonstrate that rapid renewable deployment is achievable when supported by comprehensive planning, grid infrastructure investment, and just transition policies for affected workers and communities.

Sample Question 2: Renewable Energy Investment Priorities

Question: "Governments have limited resources for energy development. Some argue these should focus entirely on renewable energy, while others believe continued investment in fossil fuels remains necessary. Discuss both views and give your opinion."

Analysis Framework:

  • Resource allocation: Government budget constraints and competing priorities
  • Energy security: Reliable supply requirements and transition risks
  • Economic considerations: Employment, industry competitiveness, and stranded assets
  • Environmental imperatives: Climate targets and pollution reduction needs
  • Technological readiness: Current capabilities and development requirements
  • International competitiveness: Global energy market positioning

Frequently Asked Questions

Q: How can I discuss renewable energy without technical engineering background?

A: Focus on well-established energy principles and widely reported research findings rather than engineering details. Learn key concepts like "grid parity," "intermittency," and "energy storage" with clear definitions. Use authoritative sources like IRENA, IEA, and government energy agencies. Emphasize policy and economic aspects where technical expertise is less critical. BabyCode's energy essentials module provides accessible explanations of key concepts used in IELTS essays.

Q: What are the most effective examples for renewable energy discussions?

A: Use well-documented national and regional programs that demonstrate different approaches and outcomes. Denmark's wind energy leadership (50% electricity from wind). Costa Rica's 95% renewable electricity achievement. Germany's Energiewende transition experience. China's massive solar deployment scale. Always explain significance: "Denmark's achievement of 50% wind electricity demonstrates that high renewable penetration is technically feasible in developed grid systems."

Q: How do I balance renewable energy benefits with challenges?

A: Present evidence-based arguments acknowledging both advantages and limitations. Discuss intermittency solutions: "While solar and wind variability creates grid management challenges, technological advances in battery storage and smart grid systems are rapidly addressing reliability concerns." Address costs realistically: "Although renewable energy requires substantial infrastructure investment, long-term operation costs are minimal compared to fuel-dependent fossil plants."

Q: Should I make predictions about energy futures in these essays?

A: Make evidence-based projections rather than speculative predictions. Reference current trends, cost trajectories, and policy commitments. Use conditional language: "If current cost reduction trends continue" or "Based on announced government targets, renewable capacity may triple by 2030." Acknowledge uncertainty while identifying likely influences on energy system evolution.

Q: How do I address fossil fuel industries and workers?

A: Discuss transition impacts sensitively while maintaining focus on evidence-based analysis. Acknowledge legitimate concerns: "Energy transitions create economic disruption for fossil fuel workers and communities, requiring comprehensive just transition policies including retraining programs and economic diversification support." Avoid dismissive language about traditional industries while supporting clean energy development.
