As an IELTS Writing Task 2 expert, I’ve observed that questions related to renewable energy and its environmental benefits have become increasingly prevalent in recent exams. This trend is likely to continue, given the global focus on sustainable development and climate change mitigation. Today, we’ll explore a question that combines these critical themes: the benefits of renewable energy in reducing pollution.
Let’s analyze a typical IELTS Writing Task 2 question on this topic:
Some people believe that the use of renewable energy sources is the most effective way to reduce pollution. To what extent do you agree or disagree with this statement?
This question requires you to consider the effectiveness of renewable energy in pollution reduction and express your opinion on the matter. Let’s break down the question and provide sample essays for different band scores.
Question Analysis
- Topic: Renewable energy and pollution reduction
- Task: Express your opinion on the effectiveness of renewable energy in reducing pollution
- Key points to consider:
- Definition of renewable energy sources
- Types of pollution (air, water, soil)
- Comparison with other pollution reduction methods
- Potential limitations or challenges of renewable energy
Sample Essay 1 (Band 8-9)
Renewable energy has emerged as a promising solution to combat the growing environmental crisis, particularly in terms of pollution reduction. While I largely agree that renewable energy sources are highly effective in mitigating pollution, I believe that a comprehensive approach involving multiple strategies is necessary for optimal results.
Undoubtedly, the widespread adoption of renewable energy sources such as solar, wind, and hydroelectric power can significantly reduce air pollution. Unlike fossil fuels, these clean energy alternatives do not emit harmful greenhouse gases or particulate matter during power generation, leading to improved air quality and reduced respiratory health risks. Moreover, the transition to renewable energy can help curb water pollution associated with coal mining and oil extraction, as well as minimize soil contamination from fossil fuel spills and leaks.
However, it is essential to recognize that renewable energy alone may not address all forms of pollution. For instance, while electric vehicles powered by renewable energy can reduce urban air pollution, they do not eliminate other sources of particulate matter such as tire and brake wear. Additionally, the manufacturing process of renewable energy technologies, such as solar panels and wind turbines, still involves some level of industrial pollution that needs to be managed responsibly.
To maximize the pollution reduction potential of renewable energy, it should be implemented alongside other complementary strategies. These may include improving energy efficiency in buildings and industries, promoting sustainable urban planning and public transportation, and implementing stricter regulations on industrial emissions and waste management. By adopting a holistic approach that combines renewable energy with other pollution control measures, we can create a more comprehensive and effective solution to environmental degradation.
In conclusion, while I strongly believe that renewable energy sources play a crucial role in pollution reduction, their effectiveness can be further enhanced when integrated with other environmental protection strategies. A multi-faceted approach that leverages the strengths of renewable energy while addressing its limitations is likely to yield the most significant improvements in overall environmental quality.

Sample Essay 2 (Band 6-7)
Renewable energy is becoming more popular as a way to reduce pollution. I agree that it is effective, but I think there are other important ways to reduce pollution too.
Renewable energy sources like solar and wind power are good for reducing air pollution. They don’t produce harmful gases like coal and oil do when they are burned to make electricity. This means cleaner air in cities and less damage to the environment. Also, renewable energy can help reduce water pollution because we don’t need to mine coal or drill for oil, which can pollute rivers and oceans.
However, renewable energy is not perfect. Making solar panels and wind turbines still causes some pollution in factories. Also, renewable energy can’t solve all types of pollution. For example, it doesn’t stop plastic waste in the oceans or chemical pollution from farms.
I think we need to use renewable energy along with other methods to reduce pollution. We should also focus on recycling, using public transport, and creating stricter laws for industries to control their waste. By combining renewable energy with these other approaches, we can make a bigger difference in reducing pollution.
In conclusion, I believe renewable energy is very effective in reducing some types of pollution, especially air pollution. But it works best when used together with other pollution reduction strategies. We need a complete plan that includes renewable energy and other methods to really solve our pollution problems.
