The graph provides information on the results of report which was taken in 2010 about energy utilization measured in billion units in Australia over the course of a half of a century, from 1980 to 2030.
Overall, it is obvious from the line graph that all fuel usage is anticipated to demonstrate upward trends, namely oil, coal, natural gas, nuclear, and solar. During the given time scale, oil is predicted to maintain its lead, meanwhile coal and natural gas used moderately, whereas solar and nuclear power accounted for the least popularity.
At the beginning of given time period, in 1980, 35 billion units of oil and15 billion units of coal was used as a source of energy, meanwhile that of for natural gas accounted for exactly 20 billion units. Until 1990, oil and natural gas experienced a gradual decrease to 30 billion and just under 20 billion, respectively, while coal witnessed a moderate rise to the level of natural gas. From 1990 to 2020, coal and oil usage followed a similar trend, increasing to 28 billion and 40 billion yearly energy usage in 2020, meanwhile natural gas experienced a mild fluctuation. From 2020 onward, oil usage is predicted to reach a peak of 50 billion, meanwhile that of for coal and natural gas to 32 and 25 billion units, respectively at the end of the given time frame, in 2030.
In terms of nuclear and solar power, whereas they started from the same level, 5 billion units in 1980, nuclear power usage is envisioned to outweigh solar one by increasing a usage so slightly to just under 10 billion units in 2030.
