IELTS Academic Writing Task 1 – Sample Test 08 (Process Diagram: Wind Turbine Electricity Generation)

Task Question

The diagram below illustrates how electricity is generated using wind turbines and then delivered to households.

Summarize the information by describing the main stages and explain how the system works.

IELTS Academic Writing Task 1 - Process Diagram of electricity generation using wind turbines with transmission to households

Figure: Electricity Generation through Wind Turbines

Sample Answer (Band 7.5–8)

The diagram illustrates the process of generating electricity through wind turbines and its subsequent transmission to households. Overall, the system converts kinetic energy from moving air into electrical energy, which is then distributed via power lines for domestic use.

Initially, the blades of the wind turbine capture energy from the wind. As the wind turns the blades, mechanical energy is transferred to a rotor connected to a shaft. This shaft drives a generator located inside the turbine housing, converting the mechanical input into electrical output.

Once the electricity is produced, it flows to a transformer, where the voltage is adjusted for long-distance transmission. From there, power lines carry the electricity to residential areas. Finally, it reaches individual households, where it can be used for lighting, heating, and other appliances.

In summary, electricity generation using wind turbines is a straightforward yet efficient process, consisting of three key stages: capturing wind energy, converting it into electricity, and distributing it to end users.

Writing Task 1 Analysis

✅ Strengths

  • Clear overview with a strong summary sentence.
  • Accurate data reporting and logical progression of ideas.
  • Good lexical variety: words like "dramatically," "modest," "steady rise."
  • Coherence maintained through effective linking.

❌ Weaknesses

  • Lack of detailed coverage of intermediate years reduces analytical depth.
  • Sentence variety is limited; more conditional and concessive clauses needed.
  • Some connectors repeated (e.g., "while," "although") → more diversity required.

📌 Suggestions for Improvement

  • Incorporate intermediate data points (e.g., 1995, 2005) to show deeper analysis.
  • Use more advanced cohesive devices: "nevertheless, conversely, in contrast, notwithstanding."
  • Vary sentence structures by adding conditional and relative clauses.
  • Highlight cause-effect: "This suggests that computer ownership became a necessity rather than a luxury."

🔑 Stronger Synonyms

  • "increase" → "escalate," "expand," "climb steadily"
  • "soared" → "skyrocketed," "surged"
  • "steadily" → "progressively," "consistently"
  • "lagged behind" → "trailed," "remained subordinate"

🔗 Useful Linking Devices

  • Contrast: whereas, in contrast, on the other hand
  • Addition: furthermore, in addition, coupled with
  • Result: therefore, consequently, as a result
  • Concession: although, even though, despite the fact that

💡 Common Collocations (Academic)

  • steady growth / significant decline
  • marked difference / noticeable increase
  • account for a proportion / represent a majority
  • remain relatively stable / witness a surge
