Global energy efficiency has become a significant topic, not only in academia but also in real-world discussions, especially regarding sustainability and climate change. Understanding trends in energy efficiency from 2000 to 2023 can provide insightful data, which is often the focus of IELTS Writing Task 1. In this article, we will look into an example question related to this topic and provide a detailed analysis and sample response.
Introduction
Energy efficiency trends feature commonly in IELTS Writing Task 1 questions, typically in the form of charts, tables, or graphs. This type of question requires students to summarize and compare the data concisely.
Sample IELTS Task 1 Question
The graph below shows trends in global energy efficiency from 2000 to 2023 in five different regions: North America, Europe, Asia, Africa, and South America. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.
(Graph/Table Example – This would show a line graph or table with data)
Analysis of the Question
In this task, you need to address the following:
- Introduce the graph/table and its main features.
- Highlight significant trends and changes over the specified period.
- Compare data across the different regions to show similarities and differences.
- Conclude by summarizing the overall trends.
Writing Sample
Introduction
The line graph illustrates the trends in energy efficiency across five regions (North America, Europe, Asia, Africa, and South America) over a 23-year period from 2000 to 2023. Overall, there has been a general increase in energy efficiency across all regions, albeit with some regional variations.
Overview
Between 2000 and 2023, all regions saw an improvement in energy efficiency. Europe and Asia exhibited the most significant growth, while Africa showed the least improvement. North America and South America displayed moderate increases.
Body Paragraph 1
In 2000, Europe and North America started at similar levels of energy efficiency, at around 55%. Over the years, Europe experienced a steep rise, reaching approximately 85% by 2023, marking it as the most efficient region. In contrast, North America’s energy efficiency grew at a slower pace, ascending to 70% by 2023.
Simultaneously, Asia started at a lower base of around 40% but saw substantial improvement, catching up with North America by 2020 and reaching 80% efficiency by 2023. Africa, despite starting from the lowest efficiency level at 30%, only managed to reach 50% by 2023, lagging behind other regions. South America showed a consistent, moderate increase from 45% to 65% over the same period.
Body Paragraph 2
A comparative analysis reveals that Europe and Asia have made the most remarkable leaps in energy efficiency, possibly due to stringent energy policies and technological advancements. On the other hand, Africa’s slower progress could be attributed to economic and technical constraints. North America and South America witnessed steady increases, though at varied growth rates, suggesting differences in national energy policies and resource availability.
Conclusion
To sum up, from 2000 to 2023, there was a significant enhancement in global energy efficiency, with Europe and Asia leading the advancements. Despite varied rates of improvement, all regions have made progress towards higher energy efficiency levels.

Key Points for Writing
- Structure: Follow the standard structure: Introduction, Overview, Body paragraphs, Conclusion. Clearly state the main trends.
- Comparison and Contrast: Use comparative language to highlight differences and similarities (higher than, lower than, as much as, while, whereas).
Vocabulary and Grammar Tips
Vocabulary to Remember
- Efficiency (n) [ɪˈfɪʃnsi]: The ability to accomplish a task with the least waste of time and effort.
- Region (n) [ˈriː.dʒən]: An area or division, especially part of a country or the world.

- Steep (adj) [stiːp]: Rising or falling sharply.
- Constraints (n) [kənˈstreɪnts]: Limitations or restrictions.
- Technological advancements (ph): Improvements in technology.
Example Usage
- “Europe exhibited substantial growth…”
- “North America’s efficiency grew at a moderate pace…”
- “Africa showed the least improvement…”
Grammar Structures
- Comparative and Superlative Forms: When comparing regions, use comparative forms (e.g., more efficient than, less efficient, the most efficient).
- Clause of Contrast: Use while and whereas for contrasting statements (e.g., While Europe saw a steep rise, Africa experienced slower growth).
Conclusion
Achieving a high score in IELTS Writing Task 1 involves accurately summarizing and comparing data, using appropriate vocabulary and grammatical structures, and presenting information logically. By understanding the trends in global energy efficiency, you can effectively tackle similar questions in your IELTS exam to achieve a Band 7+ score.
