The given line graph illustrates the changes in the consumption of five different energy sources-oil, coal, natural gas, nuclear, and solar-in Australia from 1980 with predictions until 2030, with units measured in billions.
Overall, although all five energy resources fluctuated at the beginning, they are all anticipated to experience an upward trend by the end of the period. The figure for oil was the highest among all sources of energy, and the opposite was true for solar and nuclear.
Oil consistently dominated throughout the period, starting at around 35 billion it later fel down to its lowest in 1990 which was 30 billion users, and is anticipated to remain highest among all 5 sources and increase up to 50 billion by 2030. In contrast, solar and nuclear remained lowest, both starting the period at just a little above 0, however, experienced a slight increase and rose up to around 7 and 10 billion consumers respectively, and are anticipated to reach their peak by 2030 with approximately 8 billion users for solar and 11 for nuclear.
Coal and natural gas also started the period with similar numbers, both at around 20 billion, nevertheless, demonstrated different patterns in the following years. While both followed a general upward trend, natural gas is predicted to only reach 25 billion by 2030, whereas coal is expected to peak at around 35 billion, becoming the second most consumed source among all.
