The charts below show energy source in Australia in 2008 and predictions for 2030.

Overall, the graphs show that fossil fuels continue to dominate Australia’s energy supply in both years, although their composition is expected to shift by 2030. While coal, which was the largest source in 2008, is projected to decline sharply, the reverse is true for oil and gas, which are expected to expand significantly. Despite the projected growth of renewable sources such as wind and hydro, they will still make up only a small proportion of the total, with solar’s modest share in 2008 expected to be replaced by geothermal by 2030.

  1. Lexical resource

    RevisedThe pie charts illustrate the energy sources in Australia for 2008 and the projections for 2030.

    Improved lexical choice for clarity.

In both years, coal, oil, and gas together account for almost the entire energy supply. Oil is expected to rise modestly to 35.5%, becoming the largest single source, while gas records the most substantial growth, climbing to 32%.

  1. Coherence & cohesion

    RevisedIn 2008, coal was the dominant fuel at 39%, significantly higher than oil at 32.5% and gas at 22.9%.

    Improved sentence parallelism for better coherence.

  2. Grammar & accuracy

    RevisedBy 2030, however, coal is expected to decline to 27%, a decrease of 12 percentage points, allowing oil and gas to exceed it.

    Grammatical adjustment for smoother sentence structure.

In 2008, renewables totaled only 1.8% (solar 1.30%, wind 0.30% and hydro 0.20%), while “other” accounted for 3.8%. By 2030, renewables are expected to rise to a combined 6.2%, driven largely by the appearance of geothermal at 4.30%, with wind increasing to 1.20% and hydro to 0.70%.

  1. Lexical resource

    RevisedRenewable sources and other minor contributors will see modest growth by 2030, yet remain largely marginal.

    Slightly varied language for broader lexical range.

  2. Lexical resource

    RevisedInterestingly, geothermal by 2030 surpasses the overall renewable total from 2008.

    Varied lexical choice for interest and emphasis.

  3. Grammar & accuracy

    RevisedMeanwhile, the 'other' category is expected to decrease slightly to 3.6%.

    Revised for grammatical completeness.
