Nuclear energy has been a recurring topic in IELTS Writing Task 2 exams, particularly when discussing environmental issues and sustainable energy sources. Based on past exam patterns and current global trends, it’s highly likely that questions related to nuclear energy will continue to appear in future tests. Let’s examine a relevant IELTS Writing Task 2 question and explore sample essays for different band scores.
Some people think that nuclear energy is the best solution to the world’s increasing demand for energy. Others believe it is too dangerous and that we should find alternative sources of energy. Discuss both views and give your own opinion.
Analysis of the Question
This question is a classic example of a discussion essay with an opinion element. It requires candidates to:
- Discuss the advantages of nuclear energy as a solution to increasing energy demands
- Explore the concerns about nuclear energy’s safety and the need for alternatives
- Provide a personal opinion on the matter
Let’s look at sample essays for different band scores to understand how to approach this question effectively.
Sample Essay for Band 8-9
Nuclear energy has emerged as a contentious topic in the global quest for sustainable power sources. While some advocate for its adoption as the primary solution to meet growing energy needs, others express grave concerns about its safety and push for alternative energy sources. This essay will examine both perspectives before presenting my own viewpoint.
Proponents of nuclear energy argue that it offers a reliable and efficient solution to the world’s escalating energy demands. Nuclear power plants can generate vast amounts of electricity with minimal carbon emissions, making them an attractive option for countries aiming to reduce their carbon footprint. Moreover, nuclear energy is not dependent on weather conditions, unlike solar or wind power, ensuring a consistent energy supply. The high energy density of nuclear fuel also means that relatively small amounts can produce enormous quantities of power, potentially securing energy independence for many nations.
On the other hand, critics emphasize the inherent dangers associated with nuclear energy. The catastrophic consequences of nuclear accidents, such as those in Chernobyl and Fukushima, serve as stark reminders of the potential risks. The long-term management of radioactive waste poses another significant challenge, as it remains hazardous for thousands of years. Furthermore, the initial cost of building nuclear power plants is exceedingly high, and there are concerns about the proliferation of nuclear technology for military purposes.
In my opinion, while nuclear energy does offer some compelling advantages, the risks and long-term environmental implications are too severe to ignore. I believe that a more prudent approach would be to invest in a diverse portfolio of renewable energy sources, such as solar, wind, and hydroelectric power, combined with significant improvements in energy efficiency. This strategy would not only address our growing energy needs but also ensure a safer and more sustainable future for generations to come.
In conclusion, the debate over nuclear energy as a solution to global energy demands is complex and multifaceted. While it offers significant benefits in terms of energy output and low carbon emissions, the potential risks and long-term challenges cannot be overlooked. A balanced approach that prioritizes safety, sustainability, and diversification of energy sources is essential for addressing our energy needs responsibly.

Sample Essay for Band 6-7
Nuclear energy is a topic that many people have different opinions about. Some think it’s the best way to meet our growing energy needs, while others believe it’s too dangerous and we should look for other options. In this essay, I will discuss both sides and give my opinion.
People who support nuclear energy say it’s a good solution because it can produce a lot of electricity without causing much pollution. Nuclear power plants don’t release greenhouse gases like coal or oil plants do, so they can help fight climate change. Also, nuclear energy is very powerful, so a small amount of fuel can make a lot of energy. This could help countries become less dependent on other countries for energy.
However, there are also strong arguments against nuclear energy. The biggest concern is safety. If there’s an accident at a nuclear power plant, it can be very dangerous for people and the environment. We’ve seen this happen in places like Chernobyl and Fukushima. Another problem is nuclear waste, which stays radioactive for a very long time and is hard to dispose of safely. Building nuclear power plants is also very expensive, which is another drawback.
In my opinion, I think nuclear energy is too risky to be the main solution for our energy needs. While it does have some benefits, like producing a lot of energy without much pollution, the potential dangers are too high. I believe we should focus more on developing safer renewable energy sources like solar and wind power. These might not be perfect, but they don’t have the same risks as nuclear energy.
To conclude, nuclear energy has both advantages and disadvantages. Although it can provide a lot of clean energy, the safety risks and long-term problems with waste are serious concerns. I think it’s better to invest in safer and more sustainable energy sources for our future.
