The provided line graph illustrates the main trends in expenditure of different kinds of fuel in Australia commencing from 1980 with future forecasts to 2030.
Overall, all five types of energy sources have seen an increase in use during this period. Although, natural sources like oil and coal dramatically improved in use, natural gas’ demand in Autralia followed dramatic ups and downs, whereas nuclear and solar sources of energy were the least popular and steadily changed.
During the first decade, despite some dramatic decrease in use of oil and natural gas to 30 and 17 billion units, respectively, the trend had recovered and was followed by an upward trend. In 2010 the amount of oil reached 35 billion units and it is forecasted that by 2030 it will reach almost 50 billion units. Despite the fact that coal was less popular type of fuel in the 1980s and was only 18 billion units, to 2010s it substantially increased in use, becoming the second most popular fuel in Australia after oil and reached 25 billion. In the upcoming two decades inspite of some fluctuations coal will still hold its positions and its expenditure will reach over 30 billion units per year.
Alternatives sources of energy like nuclear power energy and solar panels energy, both have reached a pleateau and had seen minor changes until 2010s. However, it is believed that by 2030 their popularity will slightly increase and will be a little bit less than 10 billion units.
