The pie charts compare the sources of electricity in one particular country in 2000 and 2020.

Overall, a coal was by far the most used resource to generate electricity in the first year given, while in 2020 the leadership was already taken by natural gas. It is also worth noting that wind & solar witnessed a significant increase in the percentage of electricity generated, becoming the second.

In 2000, almost half of the whole electricity was produced with coal, although this proportion decreased to a mere 12% in 2020. Nuclear, by contrast, experienced relatively slight drop from 18% to 15%, whereas the category ‘Other’ remained the same in both years – just 2%.

Turning to sources which saw rises by 2020, it is wind & solar which grew the most, from only 1% to a remarkable 27%. Despite this, it was second in 2020, after natural gas, which increased considerably and reached 34% in the final year. Noticeably, the smallest change was seen in hydro power, by 1% from nine to ten percentage units.

Task Response

The report effectively addresses the task by providing an overview and making relevant comparisons between the two years. The overall structure is clear, with an introduction, an overview, and detailed paragraphs. However, there are some inaccuracies in the data (e.g., coal at 12% instead of 25%, nuclear at 18% instead of 15%, 'Other' at 2% instead of 8%, wind & solar at 1% and 27% instead of 8% and 25%, natural gas at 34% instead of 28%, and hydro at 9% to 10% instead of 12% both years). These inaccuracies detract from the task achievement, as the report should accurately represent the data. To improve, ensure that all figures are correctly reported and that the overview accurately reflects the main trends. Additionally, avoid introducing categories not present in the data (e.g., 'Other'). With more precise data reporting, the response would be stronger.

Coherence & Cohesion

The report is well-organized and easy to follow, with a clear overall statement and logical grouping of information. The use of cohesive devices is generally effective, though a few transitions could be smoother. For example, the phrase 'Turning to sources which saw rises by 2020' is slightly awkward; consider 'Turning to the sources that increased by 2020' for better flow. Paragraphing is appropriate, and the progression from overall trends to specific details is well managed.

Lexical Resource

The report demonstrates a good range of vocabulary with some effective choices, such as 'witnessed a significant increase' and 'remarkable 27%'. However, there are a few inaccuracies and repetitions. For instance, 'a coal' should be 'coal' (no article), and 'the leadership was already taken' could be more naturally phrased as 'natural gas had taken the lead'. Additionally, 'wind & solar' is informal; use 'wind and solar' or 'renewables' consistently. The phrase 'percentage units' is unusual; 'percentage points' is the standard term. Overall, the lexical resource is adequate but could be more precise and varied.

Grammatical Range & Accuracy

The report shows a good range of grammatical structures with mostly accurate usage. There are minor errors, such as 'a coal' (incorrect article) and 'experienced relatively slight drop' (missing article before 'slight drop'). The sentence 'it is wind & solar which grew the most' could be more concise as 'wind and solar grew the most'. Punctuation is generally correct. The grammar is strong overall, but these small inaccuracies prevent a perfect score.
