The line graph compares the consumption of five various types of energy, namely oil, coal, natural gas, hydro, and other renewable, between 1965 and 2013, oil equivalent units are measured in billion metric tons.
Overall, it is clear that, in terms of Oil, the number of energy consumption was the highest during the whole period, the reverse trend was true for other renewable energy and hydro. It should also be noted that the changes between initial and end points of coal and natural gas were the same. In fact, as far as all individual energy types are concerned, the amount of consumption reached peak points at the end of the period.
In terms of consumed oil energy, it dipped around between 1971 and 1975, which stood at 1.5 in 1965, ending with roughly 4.2. There was a surge in the coal and natural gas consumption, rising by more or less 2.5 from nearly 1.4 and approximately 0.6 respectively. As for oil, coal, and natural gas, they observed the same tendency when they dipped in 2009.
In contrast, in terms of other renewable energy and hydro, they were far the lowest, which started from more or less similar points, but hydro overtook other renewable energy until the end of the period and other renewable energy remained flat till 1999. There was a sharp increase in the amount of hydro and renewable energy between 1999 and 2012 which underwent the same changes after 1999.
