The pie charts compare the projected popularity of various energy sources, ranging from renewable energy to those from fossil fuels, in Australia in 2008, while making projections for 2030.
Overall, despite the projected increase in the majority of energy sources, Australia will continue to rely heavily on non-renewable supplies, with the use of gas experiencing the most substantial growth and green energy showing the lowest growth rate. Interestingly, coal usage will be the only resource to decrease in its share. Notably, geothermal energy will be introduced by 2030, replacing solar energy.
Regarding the non-renewable sources, the majority of energy in Australia will mainly come from these sources. Importantly, over the 22-year period, the use of gas and oil will grow in importance while coal will decrease in its proportion. The use of gas is projected to rise from nearly 23% to 32% while oil usage will reach 35.5% by the final year, making it the most important energy resource. In contrast, despite being the most common source in 2008 (39%), the use of coal is predicted to decline sharply to approximately 22% by 2030.
Concerning other variations of energy, green energy will generally contribute a small proportion while other sources will stabilize throughout the period. Specifically, energy from wind and water will increase in their shares, reaching 0.9% and 0.7% respectively. On the other hand, solar energy will disappear by 2030, making way for geothermal energy, which will contribute more than 4% to the energy supply.
