IELTS Writing Task 2 Renewable Energy Essay
Sample Essay 1: Band 8-9 Level
Here’s a high-scoring sample essay that demonstrates excellent language use and coherent argumentation:
In the face of climate change and dwindling fossil fuel reserves, the role of technology in promoting renewable energy sources has become increasingly significant. I strongly agree that technological advancements are crucial for the wider adoption and efficiency of renewable energy, and this essay will explore the reasons behind this stance.
Firstly, technological innovations have dramatically improved the efficiency and cost-effectiveness of renewable energy sources. For instance, advancements in photovoltaic cell technology have led to a substantial increase in the efficiency of solar panels while simultaneously reducing their production costs. This has made solar energy more accessible to both individuals and businesses, encouraging wider adoption. Similarly, improvements in wind turbine design and materials have allowed for larger, more efficient turbines that can generate more power even in areas with lower wind speeds.
Moreover, technology plays a vital role in addressing the intermittency issues associated with renewable energy sources. One of the main challenges of renewable energy is its dependence on weather conditions, which can lead to inconsistent power generation. However, technological advancements in energy storage systems, such as advanced battery technologies and pumped hydro storage, are providing solutions to this problem. These innovations allow excess energy to be stored during peak production times and released when demand is high or production is low, ensuring a more stable and reliable energy supply.
Additionally, smart grid technologies are revolutionizing the way we distribute and consume renewable energy. These advanced systems use artificial intelligence and machine learning to optimize energy distribution, predict demand, and integrate various renewable sources seamlessly into the existing power infrastructure. This not only improves the overall efficiency of the energy system but also makes it easier for consumers to adopt and benefit from renewable energy sources.
However, it is important to acknowledge that technology alone is not sufficient to promote renewable energy. Supportive policies, public awareness, and economic incentives are also crucial factors. Nevertheless, technological advancements provide the foundation upon which these other elements can build, making them an indispensable component of the transition to renewable energy.
In conclusion, while multiple factors contribute to the promotion of renewable energy, technological advancements play a pivotal role. They enhance efficiency, address key challenges, and create new possibilities for integration and distribution. As we continue to face environmental challenges, ongoing technological innovation will be essential in shaping a sustainable energy future.

Sample Essay 2: Band 6-7 Level
Here’s a sample essay that demonstrates good language use but with some areas for improvement:
In recent years, the importance of renewable energy has grown significantly due to environmental concerns. Many people believe that technology plays a crucial role in promoting the use of these energy sources. I agree with this view to a large extent, and I will explain my reasons in this essay.
Firstly, technological advancements have made renewable energy sources more efficient and affordable. For example, solar panels have become much cheaper and more effective due to new technologies. This means more people and companies can now use solar energy, which helps to promote its use. Similarly, wind turbines have improved, allowing them to generate more electricity even when there’s less wind.
Secondly, technology has helped to solve some of the problems associated with renewable energy. One big issue with sources like solar and wind is that they don’t produce energy all the time. However, new battery technologies allow us to store energy when it’s sunny or windy, and use it later when we need it. This makes renewable energy more reliable and attractive to users.
Additionally, smart grids are another example of how technology is promoting renewable energy. These advanced systems help to manage the distribution of electricity from different sources, including renewables. They can balance the supply and demand of energy more effectively, which makes it easier to integrate renewable sources into our existing power systems.
However, it’s important to note that technology alone is not enough to promote renewable energy. Government policies and public awareness are also very important factors. For instance, financial incentives can encourage people to adopt renewable energy, while education can help people understand its benefits.
In conclusion, I believe that technological advancements are very important for promoting renewable energy sources. They have made these sources more efficient, reliable, and easier to use. However, we should remember that other factors also play a role in increasing the use of renewable energy.
