The provided two pie charts predict the change of contribution of 7 energy sources in Australia from 2008 to 2030.
Overall, the main changes that will occur are the increase in proportion of all items, except for the coal and other, which are predicted to host a decrease. Although there are 7 energy sources in both periods, the solar energy is going to be replaced by the geothermal one.
As for the upward patterns, the contribution of the oil will rise up by precisely 3% from 32.50% to 35.50% in 22 years. While gas energy formed just under a quarter in 2008, it will account for exactly 32% in 2030. The wind energy is reported to be tripled and allocate 1.20% of energy sources. Likewise, hydro energy is going to be almost four folded, improving from 0.20% to 0.70%.
With regard to the remaining categories, whereas coal energy was responsible for around two fifths of the share, in 2030 it will decline by exactly 12%. Other sources are going to have only a slight decrease by 0.20%, going down from 3.80% to 3.60% of the share. The wind energy in 2030 will have approximately the same percentage as the solar energy had previously.
