In October 2025 Australia hit a milestone: clean electricity generation (9.88 TWh) exceeded fossil-fuel generation (9.82 TWh) for the first time, driven by record-low coal output and contributing to a year-to-date 13.5 million metric ton cut in power-sector CO2. Over the past five years clean generation rose 77% while fossil-based generation fell 15%; utility-scale solar grew ~21% annually and total clean capacity nearly doubled from 32 GW in 2019 to 63.5 GW by end-2024. This shift signals a practical turning point for a coal- and gas-exporting economy and has material implications for emissions trajectories, market positioning and grid operations. Near-term outlook hinges on whether clean generation holds through summer (coal still supplied 44% in October), and on rapid deployment of storage and grid upgrades to avoid bottlenecks.
