The given pie charts illustrate where energy in Australia came from in 2008 and how the proportions of energy sources will change by 2030.
Overall, coal, gas, and oil were among the best sources to produce energy in Australia. Moreover, those three are predicted to continue their domination in the future, while the emergence of geothermal is expected.
Looking at the major sources, in 2008 coal was the most used, accounting for 39% of energy generated. However, although it is still considered to be among the top energy sources, its percentage may decline significantly to only 22.3% in 2030. The shares of energy produced by oil and gas at the beginning of the period were at 32.5% and 22.9%, respectively. Their figures are projected to increase 22 years later, with a modest rise to 35.5% for oil and a substantial growth to 32% for gas.
As for the remaining categories, solar, wind, and hydro energy recorded the lowest in usage at only 0.8%, 0.3%, and 0.2%, respectively, whereas other unnamed energy sources constituted 4.3% of the energy sources in 2008. In 2030, wind and hydro energy are expected to witness a slight growth, standing at 0.9% for wind and 0.7% for hydro. Finally, while the unspecified sources of energy will remain the same, a new way of generating energy is predicted to appear, as geothermal use will make up 4.3% of energy in Australia.
