The charts show the percentage of power generated from 6 different types of Gareline
Sample Response
Overall, it can be clearly seen that the highest electricity was generated by hydro in 1970, while gas generated power was lowest in 1980. Another noticeable change is that maximum power was generated in the hydropower plant.
First, the power generated in the hydropower plant was 76%, the highest power generated in 1980. However, electricity generated by gas and other was 1.4% and 1.6%, respectively. Moreover, in 1970, the wind was 5% of electricity generated.
On the other hand, the power disparity generated by gas and other was 44.8% in 1970. Afterwards, geothermal was 22% of the power generated in the same year. Notably, the wind was 7% of the power generated, but hydro approximately doubled(15.5%) of power generated in 1990. Geothermal and hydropower generated were 34% and 39%, correspondingly.
IELTS Writing Correction
- 1. Use a precise measure Original: the highest electricity Suggested revision: the largest share of electricity Why it matters: The chart reports proportions of generation rather than an amount called the highest electricity.
- 2. Fix modifier order Original: gas generated power Suggested revision: power generated from gas Why it matters: The revised noun phrase uses the correct participle structure.
- 3. Describe the proportion Original: maximum power Suggested revision: the largest proportion of power Why it matters: Proportion is more precise for values shown as percentages.
- 4. Use chart terminology Original: the power generated in the hydropower plant Suggested revision: the proportion generated from hydro Why it matters: The chart shows energy-source shares rather than output from a particular plant.
- 5. Complete the comparison Original: the highest power generated in 1980 Suggested revision: the highest proportion in 1980 Why it matters: The replacement completes the complement after the percentage figure.
- 6. Fix the subject phrase Original: electricity generated by gas and other was Suggested revision: the shares generated by gas and other sources were Why it matters: The plural percentages require a plural subject, and other needs a head noun.
- 7. Name the source Original: in 1970, the wind Suggested revision: in 1970, wind power Why it matters: Wind power is the appropriate uncountable name for the energy source.
- 8. Use a neutral transition Original: On the other hand Suggested revision: Turning to the remaining figures Why it matters: The paragraph continues the description rather than presenting a direct contrast.
- 9. Correct the time link Original: Afterwards Suggested revision: In the same year Why it matters: The sentence still reports 1970, so a later-time transition is misleading.
- 10. Express the share Original: geothermal was 22% Suggested revision: geothermal accounted for 22% Why it matters: Accounted for states a category's percentage naturally and precisely.
- 11. Express the proportion Original: the wind was 7% Suggested revision: wind accounted for 7% Why it matters: A source accounts for a percentage rather than being a percentage.
- 12. Repair the noun phrase Original: generated Suggested revision: generation Why it matters: Generated cannot function as the required noun in this subject.
Suggested Rewrites
- the highest electricity the largest share of electricity
- gas generated power power generated from gas
- maximum power the largest proportion of power
- the power generated in the hydropower plant the proportion generated from hydro
- the highest power generated in 1980 the highest proportion in 1980
- electricity generated by gas and other was the shares generated by gas and other sources were
Why this response received Band 5.0
The response has a recognizable structure and reports several correct figures, especially for 1980. However, its overview is repetitive and partly inaccurate, while the 1990 discussion confuses hydro, nuclear, and geothermal values and important categories are omitted; the response is also below the required length. The priority is to verify every category against the charts and present the principal shifts across all three years in a clear overview and comparative detail groups.
IELTS Writing Criteria Scores
Task Achievement
The response reports some accurate figures but gives an unclear overview, omits major data, and substantially mislabels the 1990 values.
State that hydro peaked in 1980 before falling, geothermal rose to lead in 1990, and support this overview with accurately checked figures from all six sources.
Coherence and Cohesion
Basic paragraphing and linking are present, but the ideas are not grouped by a clear comparison and some transitions do not reflect the relationship between details.
Group the data by the main changes over time and use linking expressions only when they accurately signal contrast, sequence, or comparison.
Lexical Resource
The vocabulary is sufficient to name categories and describe proportions, but repetition and inaccurate combinations such as power disparity and hydropower plant reduce precision.
Use precise chart language such as accounted for, rose to, fell to, and proportion, while avoiding unnecessary repetition of power generated.
Grammatical Range and Accuracy
A mixture of sentence forms is attempted, but frequent errors in clause construction, articles, and word forms make several comparisons difficult to follow.
Build each comparison with a clear subject and verb, then check articles, agreement, and comparative structures before adding more complex clauses.
