This question effectively encapsulates the debate surrounding nuclear energy, making it an ideal prompt for our sample essays. Let’s analyze this question and provide sample responses for different band scores.
Question Analysis
The question presents a balanced approach to the topic of nuclear energy, asking candidates to discuss two opposing viewpoints:
- Nuclear energy as the best solution to increasing energy demands
- Nuclear energy as too dangerous to be a viable option
Candidates are expected to:
- Discuss both perspectives
- Provide their own opinion on the matter
- Support their arguments with relevant examples and explanations
Advantages of using renewable energy sources may also be considered as a point of comparison in this discussion.
Sample Essay 1 (Band 8)
Nuclear energy has emerged as a contentious topic in the global discourse on sustainable power sources. While some advocate for its potential to meet growing energy demands, others express concerns about its inherent risks. This essay will examine both perspectives before offering a personal standpoint on the matter.
Proponents of nuclear energy argue that it offers a reliable and efficient solution to the world’s increasing energy needs. Nuclear power plants can generate vast amounts of electricity with minimal carbon emissions, making them an attractive alternative to fossil fuels. Moreover, nuclear energy is not dependent on weather conditions, unlike solar or wind power, ensuring a consistent energy supply. For instance, France derives about 70% of its electricity from nuclear power, demonstrating its viability as a primary energy source.
On the other hand, critics contend that the dangers associated with nuclear energy far outweigh its benefits. The potential for catastrophic accidents, as evidenced by the Chernobyl and Fukushima disasters, poses a significant threat to human life and the environment. Additionally, the issue of radioactive waste disposal remains a long-term challenge, as these materials can remain hazardous for thousands of years. The enormous costs involved in constructing and maintaining nuclear facilities, as well as the potential for nuclear proliferation, further compound these concerns.
In my opinion, while nuclear energy offers significant advantages in terms of energy output and reduced carbon emissions, the risks associated with its use cannot be ignored. I believe that a balanced approach, combining nuclear power with renewable energy sources, may provide the most effective solution. By gradually phasing out fossil fuels and investing in safer, more advanced nuclear technologies alongside renewable options, we can address growing energy demands while mitigating environmental and safety concerns.
In conclusion, the debate surrounding nuclear energy as a solution to global energy needs is complex and multifaceted. While it offers substantial benefits, the potential dangers cannot be overlooked. A carefully considered, diversified energy strategy that includes nuclear power alongside other sustainable sources may be the key to meeting our future energy requirements responsibly.

Sample Essay 2 (Band 7)
The debate over nuclear energy as a solution to the world’s growing energy needs has been ongoing for decades. This essay will discuss the arguments for and against nuclear power and present my personal view on this controversial issue.
Those in favor of nuclear energy argue that it is a highly efficient and clean source of power. Nuclear plants can generate massive amounts of electricity without producing greenhouse gases, unlike coal or oil-fired power stations. This makes nuclear energy an attractive option for countries looking to reduce their carbon footprint while meeting increasing energy demands. Furthermore, nuclear power is not dependent on weather conditions, providing a stable and reliable energy supply.
However, opponents of nuclear energy point out the significant risks associated with its use. The potential for devastating accidents, such as those that occurred at Chernobyl and Fukushima, poses a serious threat to human life and the environment. The problem of safely storing radioactive waste for thousands of years is another major concern. Critics also argue that the high costs of building and maintaining nuclear power plants make it an economically unsound option.
In my opinion, while nuclear energy offers some significant advantages, the risks and long-term challenges it presents cannot be ignored. I believe that investing in renewable energy sources like solar, wind, and hydroelectric power, along with improving energy efficiency, would be a safer and more sustainable approach to meeting our energy needs. These advantages and disadvantages of nuclear energy must be carefully weighed against other options.
To conclude, although nuclear energy has the potential to provide large amounts of clean energy, the dangers associated with its use are considerable. A more balanced approach, focusing on a mix of renewable energy sources and improved energy conservation, may offer a better solution to the world’s increasing energy demands.

Sample Essay 3 (Band 6)
Nowadays, nuclear energy is a hot topic because the world needs more energy. Some people think it’s the best way to get energy, but others say it’s too dangerous. I will talk about both sides and give my opinion.
People who like nuclear energy say it can make a lot of electricity without making pollution like coal does. This is good for the environment. Also, nuclear power plants can work all the time, not like solar panels that only work when the sun shines. This means we can always have electricity when we need it.
But other people think nuclear energy is very dangerous. They remember big accidents like Chernobyl and Fukushima, where many people got hurt. These accidents also made the land around them unsafe for a long time. Another problem is that nuclear waste is dangerous for thousands of years, and we don’t know how to keep it safe for so long.
I think nuclear energy has good and bad points. It can give us a lot of clean energy, which is good. But the dangers are very big if something goes wrong. I believe we should try to use more safe energy like wind and solar power instead. We should also try to use less energy in our daily lives.
In conclusion, nuclear energy can help with our energy needs, but it is also very risky. I think it’s better to focus on safer ways to get energy and to be more careful about how much energy we use.
