The line graph illustrates oil consumption in four countries – A, B, C, and D – between 2002 and 2015, measured in million barrels per day.
Overall, Country A consumed considerably more oil than the other three countries throughout the entire period, while Countries B and D showed similar fluctuating patterns with a sharp decline towards the end. Country C remained relatively stable throughout.
Country A consistently recorded the highest consumption, starting at around 8.0 million barrels per day in 2002 and rising to a peak of approximately 9.2 in 2005. It then fluctuated slightly, dipping to a low of 7.8 in 2010, before climbing back up to reach roughly 9.0 million barrels per day by 2015. Country C followed a much steadier trend, increasing gradually from 2.6 million barrels in 2002 to a peak of around 3.1 in 2009, before declining slightly to finish at approximately 2.8 in 2015.
By contrast, Countries B and D exhibited more volatile patterns. Country B rose from 1.5 million barrels in 2002 to 2.1 in 2005, dipped to 1.8 by 2008, then surged dramatically to a peak of 3.2 million barrels in 2010 – briefly overtaking Country C – before plummeting sharply to just 0.5 by 2015. Similarly, Country D increased gradually from 1.0 million barrels in 2002 to a high of 1.9 in 2011, before falling steadily to around 0.7 million barrels per day by 2015, ending as the lowest consumer among the four countries.
