The line graph illustrates data about the amount of energy from 5 sources- oil, coal, natural gas, hydro and other renewable sources which were consumed worldwide between 1965 and 2013, measured in billion metric tons.
Overall, what stands out from the graph is that there were considerable upward trends in the consumption of oil, coal, natural gas, while hydro and other renewable experienced only slight changes over the period in question. Another key feature is that oil remained the dominant source of energy throughout the entire period.
Looking at the details, as regards oil, consumption started at 1.5 million metric tons in 1965, then there was fluctuation over the next 18 years, after which it increased sharply at just above 4 million in 2013. If we look at coal, the trend was similar. Having fluctuated until 1999, consumption then rose gradually to around 4.5 in 2013. It is also noticeable that natural gas dramatically increased over the period.
By contrast, hydro and renewable resources experienced only minor changes. Other renewables levelled off until 1999 and rose slightly while hydro remained relatively erratic and finished at just under 1 million metric tons.
