In a landmark achievement, solar energy now provides nearly 20% of Australia's total electricity generation in 2025. Wind generation grew 3% in 2024 and by an average of 12% per year since 2015. As of December 2025, Australia's over 4. 29 million solar PV installations had a combined capacity of 45. 1 GW photovoltaic (PV) solar power. Data are reported as net generation, not. In 2025, Australia's electricity consumption shows a pronounced reliance on fossil fuels, with more than half, specifically 59%, derived from fossil energy sources, primarily coal and gas.
