The bar chart illustrates the energy souces in 2008 and its predictions after 22 years .
Overall, it is clear that the percentage of gas and oil increased in the past, while, coal will decrease in the future.
As the chart shows the main energy source was coal at 39.00% in 2008, while, the smallest was hydro at 0.20%. At these time the other smallest ones were wind at 0.30%, solar at 0.80%, and other sources at 4.30%. However, when it comes to 2030 , oil will replace the important positionas energy source in Australia. Gas will be at 32.00% and coal will go down sharply at 22.30%. Furthermore, new geothermal will appear at 4.30% among these sources. Others of them also increase, for example, hydro will be at 0.70%, wind will be at 0.90%, but others will stay stably.
