In 2024, Australia's electricity generation is predominantly reliant on fossil fuels, with close to two-thirds, or about 65%, coming from these sources. Coal remains the most significant contributor, generating almost 46% of the electricity. Despite the dominance of fossil fuels, clean energy sources account for more than a third of the electricity mix, with solar and wind providing around 18% and 12%, respectively. Gas also contributes substantially, at about 17%, while hydropower's role is smaller, making up nearly 5%. Other sources like oil and biofuels contribute minimally to the country's electricity generation.
To expand Australia's low-carbon electricity generation, an increased focus on wind and solar power is essential, considering their existing contribution. Expanding these sectors could significantly enhance Australia's clean energy profile and reduce its heavy reliance on fossil fuels. Additionally, Australia could look to countries like Denmark and Ireland, where wind power constitutes a substantial portion of their electricity generation, at 52% and 32% respectively. By adopting effective policies and technologies from these nations, Australia can better utilize its own abundant natural wind resources. Moreover, learning from the global approach to nuclear energy would be beneficial. Countries such as France and Slovakia, with nuclear power contributing 68% and 62%, respectively, demonstrate the potential of this reliable and clean energy source.
Historically, Australia's journey towards low-carbon electricity has seen fluctuations, particularly in hydropower, which had notable declines in the early 1980s and throughout the 2010s. However, the late 2010s marked significant growth in solar and wind energy. For instance, 2018 witnessed an increase in solar and wind generation by 3.4 TWh and 3.1 TWh, respectively, which continued in subsequent years. 2019 and beyond showed even greater increases, with solar power growing substantially, adding 6 TWh in 2019 and more in the following years. This trend reflects a growing commitment to expanding low-carbon technologies, paving the way for a greener future.
