The two pie charts illustrates the proportion of energy sources in Australia in 2008 and predictions for 2030, including seven main stages .
Overall, the most notable change can be seen that gas and oil increased dramatically in 2030, while coal decreased notably at the end of the period. Meanwhile, there were a slight change with solar, wind, hydro and the unpopular sources.
Regarding the initial year, the proportion of gas showed an upward trend prediction, with its shares increasing from 22.90% in 2008. Similarly, oil experienced moderate growth, predicting to 35.50% in 2030. By contrast, coal began with the highest proportion, showing 39% in 200. However, this shares decreasing with the projection to 22.30% in 2030.
According to the other data of energy sources, wind and hydro started at only 0.30% and 0.20, repectively in 2008, then rose to 0.90% and 0.70 in 2030, with a slight variation. In addition, solar increased from 0.80% in 2008 to 4.30% for the rest of year. Ultimately, the unpopular sources remained unchanged through the period.
