The line graph shows five different sources of energy consumption in Australia from 1980 to 2030. Overall, it can be seen that there is an upward trend for all types of energy during the period from 1980 to 2010, and this trend is predicted to continue to 2030.
The main source of energy was oil. In 1980, approximately 35 billion units of oil were used, and the consumption experienced a steady growth to about 45 billion units by 2010. The usage is projected to continue to rise and hit 50 billion by 2030.
The next highest sources of energy were natural gas and coal with 20 billion units and approximately 16 billion units, respectively, in 1980. The usage of coal and gas were the same by 2010, with each accounting for about 25 billion units. They are both expected to consistently climb and end at roughly 35 billion and 28 billion units, respectively.
The minor energy sources were nuclear and solar energy, which both started at below 5 billion units in 1980, and increased to roughly 8 billion and 6 billion units, respectively, by 2010.They are expected to reach about 10 billion and 8 billion units, respectively, in 2030.
