Nuclear energy as a power source is a topic that has appeared in IELTS Writing Task 2 several times over the past few years. Given the ongoing global discussions about clean energy and climate change, it’s likely to remain a relevant topic for future exams. Let’s explore this subject through sample essays and in-depth analysis.
Analyzing the Task 2 Question
Some people think that nuclear energy is the best solution to the world’s increasing demand for energy. Others believe that nuclear power is too dangerous and we should focus on developing renewable energy sources instead. Discuss both views and give your own opinion.
This question presents a balanced argument task, asking candidates to discuss two opposing viewpoints on nuclear energy and provide their own opinion. The main points to address are:
- The potential benefits of nuclear energy in meeting global energy demands
- The perceived dangers of nuclear power
- The alternative of focusing on renewable energy sources
- Your personal stance on the issue
Sample Essay 1 (Band 8-9)
The debate over nuclear energy as a viable solution to the world’s growing energy needs has intensified in recent years. While some advocate for its potential to meet increasing demands, others argue that the risks outweigh the benefits and that renewable sources should be prioritized. This essay will examine both perspectives before presenting my own view.
Proponents of nuclear energy argue that it offers a reliable and efficient power source capable of meeting the world’s escalating energy requirements. Nuclear power plants can generate vast amounts of electricity with minimal carbon emissions, making them an attractive option in the fight against climate change. Furthermore, nuclear energy is not dependent on weather conditions, unlike some renewable sources, ensuring a consistent power supply.
On the other hand, critics emphasize the potential dangers associated with nuclear power. The catastrophic accidents at Chernobyl and Fukushima serve as stark reminders of the devastating consequences when safety measures fail. Additionally, the issue of radioactive waste disposal remains a significant environmental concern, as these materials pose risks for thousands of years. These factors have led many to advocate for a focus on developing renewable energy sources instead, such as solar and wind power, which are considered safer and more environmentally friendly.
In my opinion, while nuclear energy does offer some advantages, the potential risks and long-term environmental impact make it a less desirable option compared to renewable alternatives. The importance of clean energy in mitigating climate change cannot be overstated, and I believe that investing in the development and implementation of renewable technologies is a more sustainable and responsible approach to meeting our energy needs.
In conclusion, although nuclear energy has the capacity to meet growing energy demands, the associated risks and environmental concerns make it a controversial choice. I firmly believe that prioritizing the advancement of renewable energy sources is the most prudent path forward, offering a safer and more sustainable solution to our global energy challenges.

Sample Essay 2 (Band 6-7)
Nuclear energy is a controversial topic when it comes to solving the world’s increasing energy needs. Some people think it’s the best solution, while others believe it’s too dangerous and we should focus on renewable energy instead. This essay will discuss both views and give my opinion.
Those who support nuclear energy say it can produce a lot of electricity to meet growing demands. Nuclear power plants don’t release much carbon dioxide, which is good for fighting climate change. Also, they can work all the time, unlike solar or wind power that depend on the weather.
However, many people are worried about the dangers of nuclear power. There have been serious accidents like Chernobyl and Fukushima that caused a lot of damage. Another problem is what to do with radioactive waste, which stays dangerous for a very long time. Because of these risks, some people think we should develop more renewable energy sources like solar and wind power instead.
In my opinion, I think renewable energy is a better choice than nuclear power. While nuclear energy can produce a lot of electricity, the risks are too high. Solar and wind power are becoming more efficient and cheaper, and they don’t have the same dangers as nuclear energy. I believe we should invest more in these technologies to meet our energy needs safely.
To conclude, nuclear energy has both advantages and disadvantages for solving the world’s energy problems. Although it can produce a lot of power, I think the risks are too great. Instead, we should focus on developing renewable energy sources for a safer and cleaner future.
