The charts show the percentage of power generated from 6 different types of Gareline
Sample Response
Overall, it can be clearly seen that the largest share of electricitythe highest electricity was generated by hydro in 1970, while power generated from gasgas generated power was lowest in 1980. Another noticeable change is that the largest proportion of powermaximum power was generated in the hydropower plant.
First, the proportion generated from hydrothe power generated in the hydropower plant was 76%, the highest proportion in 1980the highest power generated in 1980. However, the shares generated by gas and other sources wereelectricity generated by gas and other was 1.4% and 1.6%, respectively. Moreover, in 1970, wind powerin 1970, the wind was 5% of electricity generated.
Turning to the remaining figuresOn the other hand, the power disparity generated by gas and other was 44.8% in 1970. In the same yearAfterwards, geothermal accounted for 22%geothermal was 22% of the power generated in the same year. Notably, wind accounted for 7%the wind was 7% of the power generated, but hydro approximately doubled(15.5%) of power generated in 1990. Geothermal and hydropower generationgenerated were 39% and 34%were 34% and 39%, respectivelycorrespondingly.
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.
