The pie charts compare the proportions of various energy sources used in Australia in 2008 and forecasted usage for 2030.
Overall, while fossil fuels such as oil and gas are expected to remain dominant, the share of coal is predicted to decline significantly, whereas renewable energy sources, especially geothermal, are projected to see moderate growth.
In 2008, the largest share of energy came from coal, accounting for 39%, followed by oil at 32.5% and gas at 22.9%. Together, these three sources made up over 90% of total energy use. Renewable sources were negligible, with solar, wind, and hydro each contributing less than 2%. Other sources collectively comprised 3.8%.
By 2030, a noticeable shift is projected. Coal is expected to drop to 27%, while oil will slightly increase to 35.5%, becoming the most used source. Gas is anticipated to rise to 32%. Among renewables, geothermal energy will emerge significantly at 4.3%, while solar and hydro will remain under 1%. Wind energy is expected to see a minor increase, reaching 1.2%, and other sources will slightly decrease to 3.6%.
