The pie charts provided depict the percentage of 7 different energy sources in in Australia in 2008, while making projections for the year 2030.
Overall, it is clear to observe that Australia will still rely heavily on non-renewable resources including coal, gas and oil to produce energy in the future, while renewable sources, even with some growth and the appearance of geothermal, will account for a small part of the total.
In 2008, the rate of energy produced by coal accounted for the majority of the total, at 39%, which are expected to decline sharply to 22.3% in 2030. By contrast, the figure for oil was recorded at 32.5% in 2008, before being predicted to increase slightly to 35.5% in 2030, meanwhile a similar trend could be seen in the figure for gas, which are expected to rise from 22.9% to 32% in 22 years.
Regarding alternative energy sources, these collectively constituted a very small proportion in 2008, with solar, wind, and hydro accounting for merely 0.8%, 0.3%, and 0.2% respectively, while “others” made up 4.3%. By 2030, wind and hydro energy are predicted to see modest growth to 0.9% and 0.7%, while solar energy is not specifically listed in the 2030 projection. Most notably, geothermal energy, which was not recorded as a separate category in 2008, will contribute 4.3% of energy production by 2030, equal to the “others” category, which remains unchanged throughout the period.
