The given pie charts depict the main energy sources in the USA in the 1980s and the 1990s.

Overall, it is evident from both the graphs that oil was a major source of energy in both decades. Additionally, coal and natural gas collectively provided around 50% of energy in the 1980s as well as in the 1990s. Nuclear and Hydroelectric power were also two other sources of energy in the USA. However, energy produced using hydroelectric power remained same as 5% for both decades.

In 1980, oil provided the highest amount of energy accounting for 42% of the total, followed by natural gas which produced 26% of the energy during that time. Hydroelectric power as well as nuclear power supplied equal amounts of energy, which was 5%, in the country.

Although, Oil provided 42% of energy in 1980s, it reduced to just 33% in the following decade. The energy produced by coal and natural gas only differ by a few percentages. While the energy production using hydroelectric power remained same, the production of energy using nuclear power was twice as before.

Task Response

The report adequately addresses the task by describing the main changes in energy sources between the two decades. It provides an overview and highlights key trends, such as the decrease in oil and increase in nuclear power. However, there are some inaccuracies and omissions: the report incorrectly states that hydroelectric power remained the same at 5% for both decades (it actually increased from 4% to 5%), and it fails to mention the increase in coal from 22% to 27%. Additionally, the report states that nuclear and hydroelectric supplied equal amounts in 1980, but the visual description indicates nuclear was 6% and hydro was 4%. To improve, ensure all data points are accurately reported and include all significant changes. The structure is clear, but some sentences could be more concise and precise.

Coherence & Cohesion

The report is logically organized with a clear overall statement followed by specific details. However, the paragraphing could be improved: the first paragraph mixes the overview with specific data (e.g., hydroelectric power remaining at 5%), which is better placed in the detailed section. The final paragraph could be more clearly structured to separate the comparison of each energy source. Minor lapses in cohesion, such as the abrupt shift from 1980 details to the 1990s, are present but do not hinder understanding.

Lexical Resource

The report uses a good range of vocabulary appropriate for the task, such as 'depict', 'accounting for', 'provided the highest amount', and 'twice as before'. There is some repetition (e.g., 'energy' and 'provided') and a few awkward phrases like 'only differ by a few percentages' and 'remained same' which could be more natural. Overall, the lexical resource is adequate and mostly accurate, but lacks the sophistication and flexibility of a higher band. Pay attention to vocabulary repetition to improve the overall score.

Grammatical Range & Accuracy

The report demonstrates a mix of simple and complex sentence structures, but there are several grammatical errors and awkward phrasings that affect accuracy. For example, 'remained same' should be 'remained the same', 'Although, Oil provided' has an incorrect comma and capitalization, and 'the production of energy using nuclear power was twice as before' is unclear and should be 'twice that of the previous decade'. These errors, while not impeding overall comprehension, are noticeable and reduce the grammatical range and accuracy score.
