Renewable energy and its role in reducing global carbon emissions is a hot topic in IELTS Writing Task 2. This subject has appeared frequently in past exams and is likely to continue being a popular theme due to its global relevance. Let’s explore this topic through an analysis of a typical question and sample essays for different band scores.
Analyzing the Task 2 Question
Some people think that the best way to reduce global carbon emissions is to increase the use of renewable energy sources such as solar and wind power. To what extent do you agree or disagree with this view?
This question is asking for your opinion on whether increasing the use of renewable energy is the most effective method to reduce global carbon emissions. It’s an agree/disagree type question, which requires you to clearly state your position and support it with relevant examples and explanations.
Sample Essay 1: Band 8 Response
Climate change is one of the most pressing issues of our time, and reducing carbon emissions is crucial in mitigating its effects. While I largely agree that expanding renewable energy usage is a vital strategy, I believe it should be part of a multifaceted approach rather than the sole solution.
Undoubtedly, increasing the adoption of renewable energy sources like solar and wind power can significantly reduce carbon emissions. These clean energy technologies produce electricity without burning fossil fuels, thus eliminating the release of greenhouse gases during operation. For instance, countries like Denmark and Germany have made substantial progress in cutting their carbon footprint by investing heavily in wind farms and solar parks. This transition not only reduces emissions but also creates jobs in the green energy sector, providing economic benefits alongside environmental ones.
However, while renewable energy is crucial, it should not be viewed as the only solution to this complex problem. A comprehensive approach to reducing global carbon emissions must include other strategies such as improving energy efficiency, promoting sustainable transportation, and implementing carbon pricing mechanisms. For example, enhancing building insulation and upgrading industrial processes can dramatically reduce energy consumption and, consequently, carbon emissions. Similarly, encouraging the use of electric vehicles and developing robust public transportation systems can significantly cut emissions from the transport sector, which is a major contributor to global carbon output.
Moreover, it’s important to recognize that the transition to renewable energy faces challenges such as intermittency issues and the need for grid upgrades. These hurdles underscore the importance of developing energy storage technologies and smart grid systems alongside renewable energy sources. Without addressing these aspects, the full potential of renewable energy in reducing carbon emissions may not be realized.
In conclusion, while I strongly support the increased use of renewable energy as a key strategy in reducing global carbon emissions, I believe it should be part of a broader, multi-pronged approach. Combining renewable energy adoption with energy efficiency measures, sustainable transportation, and supportive policies will likely yield the most effective results in our fight against climate change.

Sample Essay 2: Band 7 Response
Global carbon emissions are a major concern in today’s world, and many people believe that increasing the use of renewable energy sources is the best solution. I agree to a large extent that renewable energy plays a crucial role in reducing carbon emissions, but I also think other measures are necessary.
Renewable energy sources like solar and wind power are clean alternatives to fossil fuels. They produce electricity without emitting greenhouse gases, which is a significant advantage in the fight against climate change. For example, countries that have invested heavily in solar panels and wind turbines have seen a noticeable decrease in their carbon footprint. This shows that renewable energy can make a real difference in reducing emissions.
However, while renewable energy is important, it’s not the only solution to the problem. Other steps like improving energy efficiency in buildings and industries, and promoting sustainable transportation, are also crucial. For instance, better insulation in homes can reduce the need for heating and cooling, which lowers energy consumption and emissions. Similarly, encouraging the use of electric vehicles and public transport can help cut emissions from the transportation sector.
One challenge with renewable energy is that it’s not always available. The sun doesn’t always shine, and the wind doesn’t always blow, which means we need better energy storage solutions. This shows that while renewable energy is very important, we need to work on other technologies too to make it more effective.
In conclusion, I believe that increasing the use of renewable energy is a very important way to reduce global carbon emissions, but it should be part of a broader strategy. Combining renewable energy with other measures like energy efficiency and sustainable transport is likely to be the most effective approach to tackling this global problem.

Analysis of Band 7 Essay
This essay demonstrates several qualities that contribute to its Band 7 score:
- Clear position: The writer agrees with the statement but also acknowledges other factors.
- Relevant ideas: The essay presents relevant points about renewable energy and other emission reduction strategies.
- Coherence: The essay is generally well-organized with clear paragraphing.
- Vocabulary: The writer uses some less common vocabulary items accurately (e.g., “carbon footprint”, “sustainable transportation”).
- Grammar: The essay uses a mix of simple and complex sentence structures with generally good control.
While this essay is strong, it lacks some of the sophistication and depth of analysis seen in the Band 8 essay, which is why it scores a Band 7.

Sample Essay 3: Band 6 Response
Many people think that using more renewable energy like solar and wind power is the best way to reduce global carbon emissions. I agree that renewable energy is important, but I don’t think it’s the only solution to this problem.
Renewable energy is good for the environment because it doesn’t produce carbon dioxide when it makes electricity. This is different from burning coal or oil, which releases a lot of harmful gases into the air. For example, countries that use a lot of solar panels have less pollution. This shows that renewable energy can help reduce carbon emissions.
However, there are some problems with renewable energy. Sometimes the sun doesn’t shine and the wind doesn’t blow, so we can’t always get electricity from these sources. This means we need to find ways to store energy or have backup power sources. Also, building solar panels and wind turbines can be expensive, which makes it hard for some countries to use them.
I think we need to do other things to reduce carbon emissions too. We should try to use less energy by making buildings more efficient and encouraging people to use public transport instead of cars. These things can also help reduce the amount of carbon dioxide we produce.
In conclusion, I believe that renewable energy is important for reducing global carbon emissions, but it’s not the only solution. We need to use renewable energy along with other methods to solve this big problem.
