The pie charts demonstrate the proportion of energy sources used in Australia in 2008 and prediction for 2030
Overall, there are 8 types of resources/categories: coal, hydro, solar, wind, gas, geothermal and other mixed resources. Solar remains a minor source in 2030. In addition, it is clear that coal, oil and gas dominate in both charts, while other resources have a small proportion. From 2008 to 2030, coal will dramatically fall, and gas will show the opposite result, as it will increase rapidly. Other small sources will remain stable, and there are no big differences compared to the previous year.
In 2008, coal was the largest energy source at 39%, followed by oil at 32.5% and gas at 22.9%. By 2030, coal is predicted to drop to 27%, while oil and gas will rise to 35.5% and 32% respectively. This shows that fossil fuels will still dominate, but the mix will shift from coal towards oil and gas.
As for smaller sources, their share remains low in both years. In 2008, solar stood at 1.3%, wind at 0.3%, hydro at 0.2%, and other at 3.8%, with no geothermal recorded. By 2030, geothermal is expected to appear at 4.3%, wind will rise slightly to 1.2%, and hydro to 0.7%. However, solar shows no change and stays negligible. Other sources remain stable at 3.6%. Overall, renewables will still play a minor role in Australia’s energy mix by 2030.
