The topic of renewable energy’s impact on power grid infrastructure has become increasingly relevant in IELTS Writing Task 2 examinations. Based on analysis of past papers and current trends, this theme has appeared in various forms over the last 5 years, particularly in questions about technological advancement and environmental sustainability. Understanding the effects of integrating renewable energy into existing power systems is crucial for how renewable energy can drive technological innovation.
Let’s examine a recent IELTS Writing Task 2 question on this topic:
Some people believe that the integration of renewable energy sources into existing power grids is causing more problems than benefits. To what extent do you agree or disagree with this statement?
Task Analysis
This question requires candidates to:
- Take a clear position on the statement
- Discuss both challenges and advantages of renewable energy integration
- Support arguments with relevant examples
- Consider technical and economic implications
Sample Essay 1 (Band 8.0)
The integration of renewable energy into traditional power grids has become a contentious issue, with some arguing that it creates more complications than advantages. However, I strongly disagree with this perspective, as the benefits of incorporating renewable energy sources significantly outweigh any temporary challenges.
Firstly, integrating renewable energy sources into existing power grids contributes substantially to environmental sustainability. By reducing reliance on fossil fuels, this integration helps decrease carbon emissions and combat climate change. For instance, Hydrogen fuel cells and clean energy technologies have enabled countries like Denmark to generate over 50% of their electricity from renewable sources, demonstrating the feasibility of large-scale integration.
Moreover, the modernization required for renewable energy integration drives technological innovation and economic growth. Grid upgrades necessary for accommodating renewable sources create jobs and stimulate investment in smart grid technologies. The impact of electric vehicles on public infrastructure has already prompted significant improvements in grid management systems, benefiting both conventional and renewable power distribution.
While challenges exist, such as intermittency and initial infrastructure costs, these are outweighed by long-term advantages. The development of advanced storage solutions and smart grid technologies continues to address these issues effectively. Furthermore, the importance of renewable energy in rural areas has demonstrated how integration can improve grid reliability and access to electricity in remote locations.
In conclusion, despite initial challenges, the integration of renewable energy into power grids is essential for sustainable development and technological advancement. The benefits clearly surpass any temporary difficulties, making it a crucial step toward a more sustainable energy future.

Sample Essay 2 (Band 6.5)
I disagree with the statement that renewable energy integration causes more problems than benefits for power grids. Although there are some difficulties, the advantages are more important.
The main benefit of renewable energy integration is that it helps protect the environment. When we use solar and wind power, we reduce pollution from coal and oil power plants. Many countries have shown this works well. For example, Germany gets lots of its power from renewable sources and has reduced its carbon emissions.
Another good point is that renewable energy helps make the power grid more modern. Companies must upgrade their equipment and systems to handle renewable energy, which creates jobs and makes the grid work better. This also helps poor areas get electricity more easily, which is important for development.
There are some problems, like the cost of new equipment and the fact that solar and wind power depend on weather. However, new technology is helping solve these problems. Better batteries can store energy for when it’s needed, and smart systems help manage power distribution more efficiently.
In conclusion, while there are some challenges with renewable energy integration, the benefits for the environment and grid modernization are more important. Governments should continue supporting this change to create a better future.
