Australia’s clean energy sector experienced a monumental year in 2024, with new data revealing it was the most significant year for renewable energy investment since 2018. According to reports from the Clean Energy Council, renewables accounted for a remarkable 40% of the nation’s total electricity supply, showcasing accelerating momentum towards its ambitious climate goals.
The year’s success was punctuated by a record-setting final quarter, where clean energy sources supplied an unprecedented 46% of electricity to the main grid. This growth was fueled by significant new infrastructure, including the connection of 1.3 gigawatts (GW) of large-scale solar and 836 megawatts (MW) of onshore wind. These tangible additions are critical steps in the journey towards achieving 82% renewable electricity by 2030, a target that requires overcoming persistent headwinds like planning delays and rising costs.
This surge in Australia is mirrored by powerful global and regional trends. The International Energy Agency’s World Energy Outlook highlights that global solar PV additions have quadrupled to 425 GW annually over the past five years, with manufacturing capacity poised to reach 1,100 GW per year. In the United States, 2024 forecasts projected a 40% expansion in solar capacity to 130 GW and an 82% increase in battery storage, pushing renewables to constitute 24% of the country’s electricity mix.
The real-world environmental impact of this transition is substantial. Analysis from the Climate Change Authority confirms that the rapid deployment of solar and wind power was the primary driver behind a reduction of over 200 million tonnes of CO2 in Australia between 2015 and 2023. As 2024’s data demonstrates, increased investment and deployment directly correlate with improved environmental outcomes, solidifying the case for continued and accelerated action in the clean energy sector.
