Reflecting on 2025: Major Achievements in Renewable Energy
As we look back on 2025, the renewable energy sector has witnessed remarkable advancements both globally and within Australia. These developments have not only accelerated the transition to sustainable energy but have also set new benchmarks for future endeavors.
Global Milestones in Renewable Energy
In 2025, the world achieved a significant milestone by surpassing 30% renewable electricity generation for the first time. This accomplishment was primarily driven by substantial growth in solar and wind energy. Since 2000, renewables have expanded from 19% to more than 30% of global electricity, with solar and wind contributing a record 13.4% in 2023.
China played a pivotal role in this global surge. The nation experienced a 45% increase in solar power capacity in 2024, reaching its 2030 goal six years ahead of schedule with nearly 887 GW installed. This rapid expansion led the National Development and Reform Commission to announce a reduction in subsidies for new projects, transitioning to market-based pricing mechanisms.
In the United States, the integration of renewable energy with technological infrastructure gained momentum. Major tech companies, driven by the growing demand for AI and computing capacity, began co-locating data centers with renewable energy sources like solar and wind, complemented by battery storage. Google's $20 billion partnership to build data centers supported by renewable power exemplifies this trend, addressing power supply reliability and advancing net-zero targets.
These global achievements underscore a collective commitment to sustainable energy solutions, setting a precedent for continued progress in the years to come.
Australia's Renewable Energy Advancements
Australia has made significant strides in renewable energy development throughout 2025. The Tasmanian government's declaration of the $1.5 billion Cellars Hill Wind Farm as a major project exemplifies this progress. Expected to create 238 jobs during its two-year construction phase and an additional 14 permanent positions upon completion, this initiative underscores Tasmania's leadership in renewable energy.
In the mining sector, companies like Rio Tinto have recognized the economic and environmental benefits of transitioning to renewable energy. Faced with rising coal costs, Rio Tinto announced plans to power its aluminium smelters with intermittent renewable energy supported by battery storage. This strategic move aims to enhance the sustainability and competitiveness of operations in Queensland and New South Wales.
Furthermore, Australia's Renewable Energy Zones (REZs) have been instrumental in coordinating the development of transmission infrastructure, facilitating the integration of renewable energy into the National Electricity Market. As of 2025, multiple REZs have been established across New South Wales, Victoria, Queensland, and Tasmania, promoting efficient and cost-effective renewable energy deployment.
These initiatives reflect Australia's dedication to reducing carbon emissions and advancing toward a sustainable energy future.
Technological Innovations and Future Outlook
The year 2025 has been marked by significant technological innovations in the renewable energy sector. The global energy transition has been characterized by a surge in solar PV installations, which increased by 35% year-on-year, and a 76% rise in energy storage installations in terms of megawatt-hour capacity. Additionally, electric vehicle sales saw a 26% increase, indicating a broad shift toward sustainable technologies.
In Australia, the focus has been on integrating renewable energy with emerging technologies. The Australian Renewable Energy Hub in the Pilbara region of Western Australia exemplifies this approach. With plans to develop up to 26 GW of wind and solar capacity to produce green hydrogen for export, this project highlights the nation's commitment to innovative renewable energy solutions.
Looking ahead, the global momentum for clean energy is expected to continue. Projections indicate that renewable energy investments will significantly outpace those in fossil fuels, with a growing emphasis on deploying clean energy technologies in emerging and developing economies.
These technological advancements and strategic investments position both Australia and the global community for a sustainable and prosperous energy future.
