As of 2023, Australia's total electricity generation was approximately 274 terawatt hours (TWh), showing a slight increase from previous years. This generation primarily came from fossil fuels, which accounted for about 65% of the total output. Specifically, coal remained the dominant source at 46%, followed by natural gas (17%) and oil (2%). In contrast, renewable energy sources contributed around 35% to the overall electricity generation, with solar power leading at 16%, wind power at 12%, and hydroelectricity at 6%.
In recent years, there has been a significant push toward renewable energy in Australia. By 2023, renewables represented 39.4% of the country’s total electricity supply, a notable increase from earlier figures. This shift was facilitated by the addition of 5.9 gigawatts (GW) of new renewable capacity, which included 3.1 GW from rooftop solar systems. The growth of utility-scale batteries, which now account for significant storage capacity, also highlights the ongoing transition to cleaner energy solutions.
Live data indicates that the energy mix varies by state, with some regions relying more heavily on coal or gas, while others utilize a greater proportion of renewables. For instance, states like South Australia are known for their high percentage of renewable generation, whereas New South Wales and Queensland still heavily depend on coal. The adoption of solar panels has significantly increased, with over 1.6 million rooftop systems installed across the country.
Overall, while fossil fuels continue to play a substantial role in electricity generation in Australia, the increasing share of renewables marks a critical shift toward sustainability. This trend is expected to continue as the country works towards its renewable energy targets and strives for a lower-carbon future.
