Task: Write an essay on the following topic:Is nuclear energy a viable solution to climate change?

Model Answer:

Nuclear energy has long been debated as a potential solution to address the issue of climate change. While it is true that nuclear power generation does not emit greenhouse gases, it is crucial to consider the various aspects and consequences associated with its utilization. In this essay, I will argue both for and against the viability of nuclear energy in tackling climate change, and provide a balanced conclusion based on the presented evidence.

Firstly, nuclear energy can be considered a viable solution due to its ability to produce large amounts of clean and consistent energy. Nuclear power plants are not reliant on weather conditions or daylight hours like other renewable energy sources such as solar and wind. This consistency allows for a stable energy supply that is essential in meeting the growing demand for energy, especially in rapidly developing countries. Additionally, nuclear energy has the potential to significantly reduce greenhouse gas emissions if it replaces fossil fuels as the primary source of energy production. According to the International Atomic Energy Agency (IAEA), nuclear power can help reduce global carbon dioxide emissions by approximately 5 gigatons annually.

On the other hand, there are several concerns associated with the use of nuclear energy that must be taken into account. One of the major challenges is the management and disposal of radioactive waste, which remains hazardous for thousands of years. The storage of this waste requires a high level of security and containment, as any leakage or accident could result in severe environmental and health consequences. Moreover, the construction and operation of nuclear power plants are costly, requiring significant financial investment and skilled labor. This presents an obstacle to developing countries, which may not have the resources to invest in this technology.

Furthermore, the risk of accidents at nuclear facilities cannot be ignored. The catastrophic events at Chernobyl and Fukushima serve as stark reminders of the potential devastation caused by nuclear energy. While advancements in technology and safety protocols have been made since these incidents, the possibility of a major accident remains a significant concern.

In conclusion, while nuclear energy has the potential to play a role in mitigating climate change by providing a clean and consistent source of power, it is essential to carefully weigh the benefits against the associated risks and costs. The long-term management of radioactive waste, the financial investment required for construction and operation, and the potential consequences of accidents must all be considered when evaluating the viability of nuclear energy as a solution to climate change. Ultimately, a diverse mix of renewable energy sources and improved energy efficiency measures should form part of an integrated approach to addressing the issue of climate change, rather than relying solely on nuclear energy.

Based on the provided model answer, the following scores can be assigned according to IELTS scoring standards:

Task Response: 9 (The response fully addresses all parts of the task, demonstrating a comprehensive understanding of the question.)

Coherence and Cohesion: 8 (The essay is well-structured and logically organized, with appropriate cohesive devices used throughout.)

Lexical Resource: 8 (The vocabulary choice is generally appropriate and varied, although some less common words could be replaced with more familiar synonyms to enhance clarity.)

Grammatical Range and Accuracy: 9 (The grammar is mostly accurate and complex, with only a few minor errors.)

Overall, the essay would receive an IELTS Band Score of 8.5.
