Space exploration and its potential for discovering new energy sources has become an increasingly relevant topic in IELTS Writing Task 2. This subject combines scientific advancement with environmental concerns, making it a prime candidate for examination. Based on recent trends, we can expect to see more questions related to space research and alternative energy in future IELTS tests.
One potential question that aligns closely with past exam topics is:
Some people think that space research is a waste of money and resources, while others believe it is essential for finding alternative energy sources. Discuss both views and give your own opinion.
Let’s analyze this question and provide sample essays for different band scores.
Question Analysis
This question requires candidates to:
- Discuss arguments for and against space research in relation to alternative energy sources
- Present their own opinion on the matter
- Support their points with relevant examples and explanations
The challenge lies in balancing the discussion of both viewpoints while clearly stating and supporting your own stance.
Sample Essay 1 (Band 8-9)
Space exploration has long been a subject of debate, with some viewing it as an unnecessary expense and others considering it crucial for humanity’s future. This essay will examine both perspectives before presenting my own view on the matter.
Those who oppose space research often argue that the enormous financial resources allocated to these programs could be better spent addressing immediate terrestrial problems such as poverty, healthcare, and education. They contend that investing in existing renewable energy technologies like solar and wind power would yield more immediate benefits for our planet’s energy needs. Furthermore, critics point out that many space missions have failed to produce tangible results, making them seem like extravagant gambles with public funds.
On the other hand, proponents of space exploration emphasize its potential to revolutionize our approach to energy production. They argue that space exploration plays a crucial role in scientific advancement, including the discovery of new energy sources. For instance, research into helium-3 found on the Moon could lead to safer and more efficient nuclear fusion reactors. Additionally, space-based solar power systems could provide a constant, clean energy supply unaffected by weather or day-night cycles. Supporters also highlight how space research drives technological innovation, often resulting in spinoff technologies that benefit various sectors on Earth, including energy efficiency.
In my opinion, while the concerns about the cost of space research are valid, its potential benefits for alternative energy sources and overall scientific progress far outweigh the drawbacks. The history of space exploration has shown that seemingly impractical endeavors can lead to groundbreaking discoveries and technologies. Moreover, as our planet faces increasing energy demands and environmental challenges, the need for innovative solutions becomes more pressing. Space research offers a unique platform for developing these solutions, potentially securing a sustainable energy future for humanity.
In conclusion, although space research requires substantial investment, its role in advancing our understanding of the universe and developing new technologies is invaluable. By continuing to explore space, we not only expand our knowledge but also increase our chances of finding revolutionary energy sources that could address our long-term needs on Earth.

Space research exploring alternative energy sources
Essay Analysis
This essay demonstrates several key strengths that contribute to its high band score:
Task Achievement: The essay fully addresses all parts of the task, discussing both viewpoints and clearly presenting a personal opinion.
Coherence and Cohesion: The ideas are logically organized with clear progression throughout the essay. Paragraphs are well-linked, and cohesive devices are used effectively.
Lexical Resource: The essay employs a wide range of vocabulary with very natural and sophisticated word choices (e.g., “extravagant gambles,” “revolutionize our approach,” “spinoff technologies”).
Grammatical Range and Accuracy: Complex sentence structures are used accurately and effectively. There is a good mix of simple and compound-complex sentences, demonstrating a high level of grammatical control.
Development of Ideas: Each main point is well-developed with relevant examples and explanations, showing depth of understanding of the topic.
Sample Essay 2 (Band 6-7)
In recent years, there has been a debate about whether money spent on space research is worthwhile or not, especially when it comes to finding new energy sources. This essay will discuss both sides of this argument and give my opinion.
Some people think that space research is a waste of money and resources. They believe that there are more important problems on Earth that need solving first, like poverty and climate change. These people argue that we should focus on developing renewable energy sources that we already know about, like solar and wind power, instead of looking for new ones in space. They also say that space missions are very expensive and often don’t give us any useful results.
On the other hand, there are those who believe that space research is very important for finding new energy sources. They say that we might discover new materials or technologies in space that could help us produce clean energy more efficiently. For example, some scientists think we could use helium-3 from the Moon to create safer nuclear power. Space research has also led to many useful inventions that we use on Earth, like solar panels and water filtration systems.
In my opinion, I think that space research is important and can help us find new energy sources. While it’s true that it costs a lot of money, the potential benefits are huge. We need to think about the long-term future of our planet and find sustainable energy solutions. Space exploration could be the key to solving our energy problems and helping us protect the environment.
To conclude, although space research is expensive, I believe it is necessary for finding new energy sources and advancing our technology. We should continue to invest in space exploration while also addressing immediate problems on Earth.
