How U.S Energy Consumption Changed Between 1980 and 2030
Overview
The line graph illustrates the changes in U.S energy consumption by different types of fuel, including hydropower, solar or wind, natural gas, coal, and petrol or oil, between 1980 and 2030. The graph shows that petrol and oil are the most consumed energy sources, while hydropower, nuclear, solar, and wind are the least consumed.
Key Features
- Petrol and oil are the highest consumed energy sources, reaching 50 quadrillion units.
- Hydropower, nuclear, solar, and wind energy consumption remains relatively constant, with nuclear energy showing a slight increase.
- Coal and natural gas consumption are closely competing, with coal consumption increasing over time.
- The graph shows a surge in petrol and oil consumption in 1995.
Our Review
We analyzed the given text and found that it provides a general overview of the graph, but lacks depth in comparing and contrasting the different energy sources. The writing is somewhat uneven, with more detail given to some aspects than others. We also noticed that the paragraphing is inconsistent, and the connections between paragraphs could be improved. To improve the writing, we suggest using more precise vocabulary and complex sentence structures. Additionally, the writer should provide a clearer overview and more insightful analysis.
However, to meet the requirements, I will revise the response as follows:

Student Submission
The line graph illustrates how U.S energy consumption changed by different types of fuel like hydropower, solar or wind, natural gas, coal and petrol or oil between 1980 and 2030.
Overall, petrol and oil are in the highest demand, when at that time hydropower, nuclear, solar and wind are in the lowest. The last four types of energy mostly remain constant where nuclear energy demonstrates better results, although all started from 4 quadrillion units. The hydropower shows the worst result, because it sank from 4 to 3.
Currently, coal and natural gas are competing with each other. Natural gas started with higher demand, but сoal consumption has been growing all the time, but then declining. It lasted between 1980 and 2015. After that, coal demand started soaring.
The best results we can see in petrol and oil, because a surge of units is seen in 1995 and raised to 50 quadrillion which is twice as much as coal
IELTS Essay Assessment
1. IELTS Writing Score: 6/9 ■■■■■□□□
2. Score Breakdown:
-
Task Achievement: 6/9 - The essay addresses the task by describing the trends shown in the graph. However, the description is somewhat uneven, with more detail given to some aspects than others. The overview is present but could be more precise and insightful. The analysis lacks depth in comparing and contrasting the different energy sources effectively.
-
Coherence and Cohesion: 5/9 - The essay is generally organised chronologically, following the time sequence of the graph. However, the paragraphing is inconsistent, and the connections between paragraphs could be improved. There's a lack of clear topic sentences and transitions to smoothly guide the reader through the data. Some sentences feel abruptly placed.
-
Lexical Resource: 6/9 - The essay demonstrates a sufficient range of vocabulary related to energy consumption. However, some word choices are imprecise (e.g., "better results" in the context of energy consumption needs clarification). There's some repetition of vocabulary ("demand," "consumption").
-
Grammatical Range and Accuracy: 5/9 - The grammar is generally accurate, but there are instances of incorrect sentence structures and tense inconsistencies. The writing lacks complexity in sentence structures. There are some minor grammatical errors that affect the flow and clarity.
3. Error Analysis:
-
Vocabulary Errors:
- [
better results] -> [ higher production/greater output ] : "Better results" is vague in this context. More precise language is needed to describe energy production. - [
soaring] -> [ increasing rapidly/sharply increasing ] : While "soaring" is acceptable, more precise vocabulary would improve the essay. - [
sank] -> [ decreased/fell ] : "Sank" is slightly informal for an academic context.
- [
-
Grammar Errors:
- [
The last four types of energy mostly remain constant where nuclear energy demonstrates better results, although all started from 4 quadrillion units.] -> [ The last four types of energy remained largely constant, although all started from 4 quadrillion units; nuclear energy showed the most significant increase.] : This sentence is long and awkwardly structured. Splitting it improves clarity and grammatical accuracy. The use of a semicolon improves the flow. - [
It lasted between 1980 and 2015.] -> [ This trend lasted from 1980 to 2015.] : The pronoun "it" is unclear. Rephrasing clarifies the reference. - [
The best results we can see in petrol and oil, because a surge of units is seen in 1995 and raised to 50 quadrillion which is twice as much as coal] -> [ Petrol and oil show the most significant increase, with consumption surging to 50 quadrillion units by 1995—double the amount of coal.] : This sentence is grammatically incorrect and poorly structured. The revision improves clarity and grammatical accuracy using stronger vocabulary.

4. English Model Essay:
The line graph illustrates changes in U.S. energy consumption from 1980 to 2030, broken down by fuel type: hydropower, solar and wind, natural gas, coal, and petrol/oil.
Overall, petrol and oil consistently dominated energy consumption, while hydropower, nuclear, solar, and wind remained relatively low and stable throughout the period. Coal and natural gas exhibited competing trends, with natural gas initially holding a larger share before coal experienced a period of growth followed by a decline.
Initially, natural gas consumption exceeded that of coal. However, coal consumption steadily increased until 2015, after which it began to decline. In contrast, petrol and oil consumption showed a dramatic surge, reaching 50 quadrillion units by 1995—double the consumption of coal at that time. Hydropower, nuclear, solar, and wind energy sources remained relatively constant, with nuclear energy showing the most substantial, albeit modest, growth. The consumption of hydropower, however, slightly decreased over the period. The projected data for 2030 indicates a continued dominance of oil and gas.
