Writing about a line graph with a future prediction.
Here is a line graph from the Cambridge IELTS 9 book about US energy consumption by fuel type. As you can see, there is a date range from the past with predictions for the future. Always take around 2 minutes to analyse the task before writing anything. Give yourself 4 minutes in total to plan out what you will write.

Static and Dynamic data
- Static data means that the chart or graph displays one period of time.
- Dynamic data shows two or more periods of time and how trends change over a period of time.
Different language will be used for static charts and dynamic charts. Before you begin writing, always make sure that you first analyse the chart or graph to see if it is one time period or if the data is changing over time. Take 2 minutes to analyse the graph or chart because If you use trends language for a static chart then you will lose marks for grammar.
Analysing the task
Rubric: On the vertical axis it shows energy consumption in units of a quadrillion. On the horizontal axis, it shows the date range from 1980 to 2030 (history and projections)
Paragraphing: I need a short paraphrased introduction, an overview and 2 main body paragraphs. No conclusion is needed. Word count would be over 170 words for a fully developed answer (150 words minimum)
Trends: The graph shows dynamic data. This means that there are changes over time. It is evident that fossil fuels (coal, gas, oil) show the highest consumption with predicted increases, while cleaner energy (wind, hydro, solar, nuclear) have the lowest consumption and will remain relatively low.
Grouping the data: Straight away I can see that the best way to group the data would be in these two categories (fossil fuels and cleaner fuels) by grouping the data you will gain marks for coherence and cohesion.
Grammar: I will need to use the past tense / present perfect and language for future predictions.
