The provided line graph depicts data about five different sources of energy consumption in Australia during the period from 1980 to 2030 (in billion units).
Overall, it can be seen that all types of energy from 1980 and 2030 witnessed an upward trend with oil remained the highest figures over years and solar recorded the lowest one. This trend is predicted to be continue to 2030.
The main source of energy was oil, which started at the number of approximately 35 billion by 1980 before showing a steady growth to about 40 billion units in 2000. The usage is predicted to continue to rise and hit 50 billion by 2030. The next highest energy sources were coal and natural gas, which each accounting for 20 billion and around 17 billion units in 1980, respectively. This two sources experienced a consistent climb, reaching the same number of 25 billion units in 2010. Theyare both expected to end at around 35 billion units and 28 billion units, respectively.
Turning to the minor figures, nuclear and solar reported modest numbers of 5 billion units and 2 billion units by 1980. Theirs figures increased sharply, hitting about 9 billion units and 8 billion units by 2010. They are expected to reach approximately 11 billion and 9 billion at the end of the period. The sheer disparity between oil energy and solar energy is stand out, illistrating the common use of oil in daily basis
