The graph illustrates the amount of oil usage in the US, China, the Middle East, Western Europe and Japan between 2009 and 2030.
Overall, it is readily apparent that the most significant change is projected to be a dramatic and marked decrease in oil consumption of the US and Western and Japan respectively, whereas China and the Middle East are set to see a marginal rise over the given period.
To begin with, at the beginning of the period, the US was dominant in oil consumption at 10 million barrels, after which it almost remained at this point until 2015. However, it then started to decline significantly by the present day, and it is likely to continue to do so by the end of the period.
If we look at statistics of the other two areas, China and the Middle East, they were the lowest consumers of the oil in 2009, with around 2 millions of barrels each. After some years, the amount of oil usage in both countries increased, where China showed a faster growing trend than the Middle East for the majority of the time described. Despite the growing-faster oil usage of China than the Middle East, it is projected that the oil usage in both countries will be at the same level by 2030.
Finally, in Western Europe and Japan oil consumption was in second place among the given countries. For some reason, the figure began to decrease noticeably and might continue at this rate by 2030.
