The two pie charts illustrate the distribution of energy sources in Australia in 2008 and projections for 2030.
Overall, non-renewable sources dominate in both years, although their shares are expected to shift considerably. Coal, the leading source in 2008, is predicted to decline sharply, while oil and gas are set to become the major contributors. Meanwhile, renewable sources remain minor, though geothermal energy is projected to appear in 2030.
In 2008, coal accounted for the largest proportion at 39%, followed by oil at 32.5% and gas at 22.9%. By 2030, coal’s chare is expected to drop significantly to 22.3%. In contrast, gas is forecast to rise markedly to 32%, while oil will se a modest increase to 35.5%, making it the dominant energy source.
Regarding renewable energy, solar contributed 0.8% in 2008 but is not projected to be used in 2030. Wind and hydro are expected to rise only slightly, from 0.3% to 0.9% and from 0.2% to 0.7%, respectively. A notable change is the introduction of geothermal energy, forecast to comprise 4.3% in 2030. The category of “others” is predicted to remain stable at 4.3%
