IELTS Writing Task 2 Prompt
Some people hold that the development of technology leads to environmental pollution and energy shortage. What do you think?
Band 8 Model Essay
This essay builds a balanced argument across five short sections: an introduction, three body paragraphs, and a conclusion. Each part is labeled below so you can follow the logic from problem to solution.
Introduction
By 2030, the data centres powering artificial intelligence are expected to expand so quickly that their demand for cooling water, their noise pollution, and their need for rare earth minerals will drive a scale of resource extraction unmatched since the discovery of petrochemicals. This confirms that unregulated technology genuinely strains the environment, though the same innovation, once properly incentivised, also offers the most realistic path to reversing that damage.
Body Paragraph 1
This is not a distant hypothetical. Data centres already consume electricity on a scale comparable to a small country, and their constant cooling systems draw on the same freshwater supplies that nearby communities depend on. The rare earth metals needed for their servers, meanwhile, are extracted through mining that can strip forests and pollute rivers for decades. At the consumer level, discarded smartphones and laptops pile up as electronic waste in landfills across the developing world, where informal recycling exposes workers to toxic metals. These costs are real and rising, not speculative.
Body Paragraph 2
Yet the same innovation that created this strain has also made cleaner alternatives newly affordable rather than aspirational. The cost of solar panels has fallen by roughly ninety percent over the past decade, to the point that installing rooftop solar can now pay for itself within a few years for an ordinary homeowner, not only a government-subsidised project. As population growth keeps pushing demand for raw materials upward, prioritising the replenishment of what is already extracted matters just as much as finding new sources, and some of that future demand may eventually be met by mining materials in space rather than stripping them from Earth.
Body Paragraph 3
What determines whether technology helps or harms the environment is rarely the technology itself but the incentives surrounding its use. Left purely to market forces, companies will keep choosing the cheapest available method, which is usually the most polluting one, because clean alternatives still cost more to adopt in the short term. Only when governments impose a real cost on emissions, through carbon pricing or strict efficiency standards, does clean technology become the economically rational choice rather than a voluntary one.
Conclusion
In conclusion, the scale of data-centre growth expected by 2030 shows that technology’s environmental cost is not hypothetical, but the same falling cost curve that made rooftop solar affordable also shows how quickly clean alternatives can scale once the incentives are right. The deciding factor is not the technology itself but whether policy, not the market alone, makes the cleaner option the cheaper one.
Why This IELTS Writing Task 2 Technology Environmental Pollution Essay Scores Band 8
This essay hits all four IELTS marking criteria at a high level. Here is a full breakdown of each one, so you can see exactly what raises the score.
Task Response. The essay gives a clear, balanced opinion instead of picking one extreme side. It backs the argument with specific facts, like data-centre growth and falling solar costs. Every claim gets real evidence, not just an assertion. This balance is exactly what the prompt asks for, and it is what separates a Band 8 answer from a one-sided Band 6 response.
Coherence and Cohesion. Ideas progress logically from the problem to the solution. Phrases like “yet the same innovation” and “in conclusion” tie each paragraph to the last. As a result, the reader never has to guess how one idea connects to the next. Each paragraph also opens with a clear topic sentence, which makes the structure easy to skim.
Lexical Resource. Topic-specific terms such as “carbon pricing,” “resource extraction,” and “efficiency standards” show precise, wide-ranging vocabulary used naturally. The writer also varies verb choice instead of repeating “cause” or “affect” throughout. That variety signals genuine command of the topic, not memorized phrases.
Grammatical Range and Accuracy. The essay uses long, accurate, and varied sentence structures throughout. It also mixes in shorter sentences for contrast and emphasis. This range aligns with what the official IELTS scoring criteria reward at Band 8.
