The pie charts below compare the proportion of energy capacity in gigawatts (GW) in 2012 with predictions for 2030.
Sample Response
Overall, fossil fuels werefossil fuel was by far the largest energy sourcebiggest energy sector while it was flexible capacity made up“flexible capacity” that made up the smallest shareamount in 2012. These two energy sources will remain at opposite endson two opposite ends of the spectrum though the share of the former will have fallen significantly by 2030. It is also worth noting that the total energy capacityproduction is expected to double by 2030in the future. Focusing on non-renewable sources of energy first, the proportion of capacity supplied by fossil fuelsenergy produced by fossil fuel constituted roughly two-thirds in 2012, yet it is predicted that it will fall by 20 percentage pointsfall by 20% 1828 years later. Nuclear energy, which accounted for 6% of the total energy capacity, will also have shrunk slightly. In contrast, the figure for flexible capacity is set to double, making up 2% in 2030. Non-renewable energy sources, on the other hand, are generally expected to grow in use. The most noticeable change will be in solar power generation, with a nine-fold increase from a mere 2% in 2012. Similarly, more than twice as much energynearly twice as much energy will be produced from wind in 2030 as it was in 2012, with the figures at 12% and 5%, respectivelywith respective figures being 5% and 12%. By contrast, the figure for other renewables will have experienced a negligible drop of 3 percentage pointsdrop of 3% by 2030 from just over a fifth in the first year. Finally, total energy capacityproduced will increase twofold, hitting 10.569 GW. Delete#task1 252 words,
Why this response received Band 7.5
The response presents a clear overview and organizes the figures into sensible energy groups, with most proportions and the doubling of total capacity reported accurately. Its main weakness is a small cluster of factual or labeling errors, including describing renewables as non-renewables, giving the interval as 28 years, and calling the wind rise merely twofold. Check category labels and calculate changes precisely before finalizing comparisons.
IELTS Writing Criteria Scores
Task Achievement
A clear overview and strong selection of figures are undermined by the incorrect 28-year interval, the renewable-category mislabeling, and an imprecise description of wind growth.
Verify every category name, time interval, and calculated change directly against the charts before submitting.
Coherence and Cohesion
The response progresses logically from the overview to grouped details, although presenting everything as one dense paragraph weakens the visible organization.
Separate the overview and the two main comparison groups into distinct paragraphs to make the progression immediately clear.
Lexical Resource
A broad and generally precise range describes proportions, forecasts, and changes effectively, with only occasional inaccurate terminology.
Use exact category terms consistently, especially when distinguishing renewable from non-renewable sources.
Grammatical Range and Accuracy
Varied complex structures are handled with strong control, and the few awkward constructions do not impede meaning.
Refine comparative phrasing such as the description of the wind increase to make relationships fully exact.
