The given charts illustrate various energy resources in Australia in 2008 and the foreseen proportions for 2030.
Overall, coal, gas, and oil will consistently account for the highest percentages in 2030. Moreover, other renewable resources will remain minor contributors, in spite of some growth, especially the emergence of geothermal in the prediction.
In 2008, coal dominated non-renewable energy sources at 39 percent, followed by oil at 32.5 percent and gas at 22.9 percent. By 2030, however, oil is expected to become the primary energy source, rising slightly to 35.5 percent. Gas is also projected to see a significant increase to nearly one third, with 32 percent. In contrast, the percentage of coal will considerably decline to 22.3 percent, which is predicted to be the third-largest fossil fuel.
Regarding the others, in 2008, solar, wind, and hydro power made up 0.8 percent, 0.3 percent, and 0.2 percent in that order, while that of ‘others’ was 4.3 percent. In the 2030 projection, wind and hydro power will experience a slight increase to 0.9 percent and 0.7 percent, respectively, but solar is not specifically listed. Furthermore, despite an initial absence, geothermal energy is anticipated to account for 4.3 percent of total energy sources in the prediction. This matches that of the ‘others’ category, which is forecast to remain constant.
