Sample Response
The charts illustrate the proportions of energy produced by hydro, geothermal, wind, gas, nuclearHydro, Geothermal, Wind, Gas, Nuclear and others frombetween 1970 to 1990. Overall, it is apparent that the amount of power generated increased over the years except for Hydropower in 1990.
In a more detailed analysis, in 1970, Hydropower accounted for 45% of the total energy yielded, which was just over double the proportion generated from geothermalwhich almost doubled the energy obtained from geothermal. Power from wind, gas and other sourcesPower from wind, Gas and other forms of careline accounted for relatively small sharesis insignificant, whereas nuclear energy was not generated at all.
Turning to the power generated in 1980, about three-quarters of it was from hydro, at 76%hydro which is 76%, while the other sourcesguidelines accounted for the remaining quarterremaining one quarter. Geothermal, wind and nuclear powerwind and Nuclear Power differed from one another by one percentage pointwere one per cent greater than one another, that is, 8%, 7% and 6%, respectively. Furthermore, Gas and other sourcesGas and other forms of gasoline produced less than 2% of power eachless than 2% power.
Finally, in 1990, relatively similar proportions of hydro and geothermal energy were generateda relatively similar rate of hydro and geothermal energy was yielded, 34% and 39%, respectively. Similarly, the percentage of power from gasthe percentage of fuel from Gas and other forms wasis almost the same. They are 2.5% and 2%, accordingly. Wind accounted for 7% of powerThe wind gave 7% of power, almost half the 15.5% share of nuclear powerwhich is almost half the proportion of nuclear power, which is 15.5%.
Why this response received Band 6.5
The response is strongest in its detailed coverage: it reports most percentages accurately and compares the sources clearly within each year. However, the overview wrongly describes growth in the amount of power rather than changes in percentage shares, and it misses the decisive shift from hydro to geothermal leadership. Rewrite the overview around the dominant sources and the major redistribution of shares, then retain the accurate numerical support.
IELTS Writing Criteria Scores
Task Achievement
Most categories and figures are reported accurately, but the overview misinterprets percentage shares as total power growth and omits the change in the leading source.
Summarise that hydro dominated in 1970 and 1980 before geothermal became largest in 1990, while gas and other sources remained minor.
Coherence and Cohesion
The response progresses logically through the three years, with clear paragraphing and generally effective linking between comparisons.
Make multi-item comparisons more direct so that relationships such as the one-point sequence do not require rereading.
Lexical Resource
There is sufficient range for describing proportions and comparisons, though inaccurate choices such as 'guidelines,' 'gasoline,' and 'yielded' reduce precision.
Use consistent chart vocabulary, especially 'energy source,' 'accounted for,' and 'share of generation.'
Grammatical Range and Accuracy
A mix of simple and complex sentences communicates the data clearly, although errors in comparison structures, articles, and tense recur.
Check comparative clauses and keep past tense consistent when reporting figures from historical years.
