The provided pie charts illustrate energy sources in one specific country, Australia in 2008 and projection for 2030.
Overall, while the share of four sources are expected to increase, that of one will decrease and only one will remain the same. Coal made up by far the largest proportion in the first year, but it is not expected to do so in 2030. Oil, on the other hand, will demonstrate the largest portion, becoming the dominant non renewable source. Notably, solar power will be replaced by geothermal energy.
In 2008, non-renewable energy sources made up the largest percentage. Coal, being the dominant energy resource, comprised 39%. This was followed by oil and gas with 32,50% and 22,90%, respectively. Meanwhile, other types of resources amounted to 4.30%. In contrast, renewable energies (solar, wind, hydro) allocated the smallest percentage, just under 1%.
As for 2030, non-renewable energy are estimated to dominate. Coal and gas are expected to illustrate a sharp increase. The former accounting for 35.50% and the latter 32%, followed by coal constituting approximately a quarter (22.30%). Notably, the forecast reveals that the segment of alternative energy will undergo an increase. Wind and hydro are expected to increase from 0,30% and 0,20% to 0,90% and 0,70%, respectively. As regards solar power, its usage will be replaced by geothermal, comprising 4.30%, more than the former energy for 4%. Similarly, other power supplies is anticipated to stay the same for 4.30%.
