The two pie charts illustrate the sources of energy in Australia in 2008, along with projections for 2030. Overall, coal was the most used energy source in 2008, while oil is expected to be the predominant energy source by 2030. The forecast indicates that the use of gas is projected to increase significantly, whereas other energy sources are expected to remain unchanged.
According to the data, the proportion of gas is anticipated to rise from 22.9% in 2008 to 32% in 2030. While coal was widely used in 2008, its usage is predicted to decline by 2030. Solar energy and a newly introduced energy source, geothermal, are expected to replace some of the reliance on solar power, which was only 0.3% in 2008. Geothermal energy is expected to account for approximately 4.3%, significantly higher than solar energy.
There will also be a slight increase in the percentages of wind and hydro energy sources, predicted to be 0.9% and 0.7%, respectively. Wind energy usage was 0.3% in 2008, but it is expected to increase to around 0.9% by 2030.
