The line graph illustrates the number of consumption of oil, coal, natural cas, hydro and other renewable between 1985 and 2013. Units are measured in billion million tons of oil equivalent.
Overall, the consumption of energy increased over all period. The number of oil consumption experienced the highest level of growth and became the most consumed energy instead of the number of other renewable, which stayed the smallest during all time.
The number of consumption of oil, coal and natural gas was the highest among all types of energy. Starting as the most purchased energy at 1.5 billion tons in 1965 and surging to more or less 2.7 billion tons, oil was erratic before stabilizing to approximately 2.6 billion in 1981 and plunging to around 4.3 billion tons in 2013. The number of coal was erratic between just under 0.5 billion tons in 1965 and just over 3 billion tons in 2013. Likewise, the number of natural cas soared from around 0.6 billion tons in 1965 to roughly 3.1 billion tons.
As for numbers of hydro and other renewable, they showed the similar pattern of growth, however, experienced the smallest increase. There was a steady rise in the number of hydro, which stood at just over 0 billion in 1965, but had increased slowly to just under 1 billion tons by 2013. Although the number of other renewable remained stable around 0.1 billion tons from 1965 to 1999, it had grow at a slow pace to approximately 0.4 billion tons in 2013.
