The given graph illustrates how much oil was produced and consumed in China over the 24-year course from 1982 to 2006.
Overall, it is evident that oil output and consumption in China witnessed an upward trend over the examined span, despite an 8-year stability recorded in both figures. Also of note is that the gap between the two surveyed subjects was widened significantly by the end of the period.
Looking first at the amount of oil manufactured, starting at just over 2 millions of barrels each day, its figure had risen moderately to exactly 3 million by 1986 before remaining stable until 1994. During the next 12 years, oil output rate grew steadily to end at around 3.5 million barrels per day in the final surveyed year.
Turning next to the oil consumption rate, no changes were observed in the number of oil barrels consumed per day in the first eight years (2 million oil barrels). In 1990, this figure started to increase exponentially to reach a peak of approximately 6.3 million in 2006, surpassing production of oil in 1993. Owing to this dramatic growth, oil usage rate was more than three times as much as that of its starting point and almost double that of oil output at the end of the span.
