The pie diagrams illustrate power supply in Australia in 2008 and their predicted version for 2030.
Overall, gas, oil, and coal are the main sources of energy in Australia in both years. All sources observed a rise in their usage during the timeframe except for coal and unnamed power options.
Regarding the 3 most popular power supplies, in 2008, Australians mostly used coal for energy, accounting for 39% of overall power distribution. However, it is predicted to undergo a decrease of 16.7% in its proportion, making it drop to 22.3% in the latter year. Meanwhile, oil, the second largest source of energy, is expected to see a modest rise of 3% in its popularity. Consequently, this will make oil the most preferred power supply. Lastly, it is assumed that there will be a sharp uplift of 9.1% in gas usage, which will make it the second largest energy source in the future, surpassing that of coal.
Concerning remaining types of energy production, wind, hydro, geothermal, and others are anticipated to slightly increase in their usage. Specifically, wind and hydro are forecasted to observe growths of 0.6% and 0.5% to 0.9% and 0.7% in 2030, respectively. Furthermore, it is also foreseen that there will be an increasing preference for geothermal, as it will be at 4.3% in 2030, and the elimination of solar power. Finally, other sources of energy, which comprise 4.3% of overall data, will remain relatively the same in 2030.
