The two pie charts compare the percentage distribution of electric energy production , which is a major source of energy in USA, between 1970 and 1980.

Overall, coal accounted for the largest proportion in both charts, whereas nuclear represented the smallest share. Although there were some changes over time, the general distribution pattern remained broadly similar.

In 1970, coal made up the largest segment, accounting for 47% of the total. This was followed by natural gas, which represented 24%. Meanwhile, hydro and oil contributed moderate proportions, at around 16% and 12% respectively. The smallest proportion was recorded for nuclear, at just 1%.

By 1980, there were noticeable changes. Although coal remained the dominant category, its share rose to 51%. In contrast, natural gas decreased to 15%, while hydro and oil experienced a more slight change drop to 12% and 11%. Nevertheless, nuclear continued to represent the smallest proportion at 11%.

Task Response

The report effectively summarizes the information presented in the pie charts, providing a clear overview of the changes in electric energy production between 1970 and 1980. The description of the data is accurate and well-organized. To improve, ensure that all numerical values are precisely stated and avoid minor inaccuracies (e.g., the nuclear proportion in 1980). Also, 'hydro' experienced a slight change drop to 11% rather than 12%.

Coherence & Cohesion

The report is generally well-organized with a clear introduction, overview, and detailed descriptions of each chart. The information is presented logically, and the use of cohesive devices is adequate. However, there's room for improvement in paragraphing and transitions to further enhance the flow of the report.

Lexical Resource

The report demonstrates a good range of vocabulary suitable for describing the data. Terms like 'proportion,' 'segment,' 'dominant category,' and 'noticeable changes' are used appropriately. To further enhance the lexical resource, consider incorporating more varied synonyms and precise language to describe the changes and proportions.

Grammatical Range & Accuracy

The report demonstrates a good command of grammar with a variety of sentence structures. There are a few minor errors, such as the slight inaccuracy in describing the change in hydro and oil, and the final proportion of nuclear energy. Addressing these small inaccuracies will improve the overall grammatical accuracy.
