Understanding the Task Type
The analysis of electricity generation data across different countries is a common topic in IELTS Writing Task 1. This type of question typically presents data in line graphs, bar charts, or tables showing energy production trends over time.
Electricity Generation Comparison Chart Three Countries 2000-2023
Sample Task
The line graph shows electricity generation by type in three countries between 2000 and 2023.
Model Answer
The line graph illustrates the changes in electricity generation across three countries over a 23-year period from 2000 to 2023.
Overall, while Country A maintained the highest electricity production throughout the period, Country B showed the most significant growth, and Country C experienced moderate increases with some fluctuations.
Country A started with approximately 3,500 TWh in 2000 and demonstrated steady growth, reaching 4,800 TWh by 2023. The trajectory showed consistent upward movement, particularly between 2010 and 2015, when production increased by roughly 500 TWh.
In contrast, Country B began at a much lower level of 1,200 TWh but experienced rapid growth, especially after 2010. Its electricity generation more than tripled, reaching 3,900 TWh by 2023, nearly matching Country A’s output. The most dramatic increase occurred between 2015 and 2020, with a rise of approximately 1,000 TWh.
Country C showed the most modest growth pattern, starting at 800 TWh and reaching 1,500 TWh by 2023. Notable fluctuations occurred between 2015 and 2020, when production temporarily declined before recovering.
