The given line graph illustrates the oil consumption of four distinct users from 2009, along with projections extending to 2030.
Overall, it is likely that the amount of oil consumed in China and the Middle East increased, while the figures for the USA, Western Europe, and Japan decreased slightly. Also of note is that the USA was by far the biggest consumer of oil from 2009 until the present and is predicted to remain the biggest consumer until 2030.
To elaborate, in 2009, the oil consumption in the USA started at under 10 million barrels, after that, it reached a peak of 10 million barrels in 2015 and will decrease to 8 million barrels in 2030 but is still predicted to be the biggest consumer in all surveyed nations. Similar trends can be observed in the figures for total oil consumption in Western Europe and Japan, which are projected to decline steadily from 4 million barrels to about 3 million barrels in 2015 and 2 million barrels in 2030, respectively.
During the remainder of the timeline, the Middle East’s oil consumption increased from about 2 million barrels in 2009 to 3 million barrels over the following 6 years, with a steady increase predicted to reach 3 million barrels in 2030. Whereas the figure for China increased from 2 million barrels to 4 million barrels in 2015 and a decrease to approximately 3.5 million barrels is anticipated at the end of the term.
