The given pie charts simultaneously provide information about a variety of energy sources in Australia in 2008, and the anticipation after 22 years. Overall, The 3 main sources of energy, which are gas, coal, and oil, share the relatively same percentage in both timelines. Oil energy could also be seen to overtake the priority of coal in 2030.
Regarding the state of energy sources in Australia in the past, it is noticeable that coal energy was leading the chart (39%), followed by oil energy (32.5%) and gas (22.9%) in third place. Moreover, little less commonly used energy sources like solar, wind, and hydro remained under 1% of the category. Worth mentioning is that other energy sources only took up 4.3%.
Moving on to the speculation of Australia’s future energy distribution, we can expect a big change in the energy priorities. To be more specific, coal energy would drop down to 22.3%, taking the third spot out of the main energy sources. Gas energy could be seen to seize second place (32%), leaving oil energy to be the most-used fuel out of all (35.5%). Additionally, the discovery of geothermal energy would grant itself a spot on the chart, taking up 4.3%. Noteworthily, the percentage of geothermal energy seems to be identical with that of other energy sources. Looking at the distribution of wind and hydro energy, they would continue to remain under 1% while the solar energy would be exterminated from the chart.
