As we move through mid-2026, the imperative to accelerate the global energy transition remains a top priority for nations worldwide. With climate targets looming and energy security concerns driving policy, understanding the current state of renewable energy adoption is more critical than ever. Tracking the growth of clean power sources provides vital insights into our collective progress and the challenges that lie ahead in building a sustainable future.
Our featured chart, "Global Renewable Energy Installed Capacity by Source (End of 2024)," offers a comprehensive look at how different renewable technologies stood two years ago. It clearly illustrates the impressive scale of global renewable energy deployment, with solar PV leading the charge at a remarkable 1,865 GW of installed capacity. Hydropower and wind energy also feature prominently, showcasing their significant contributions to the world's clean energy portfolio, based on the latest available statistics from the International Renewable Energy Agency (IRENA).
While this data reflects the landscape at the close of 2024, it provides an invaluable benchmark for understanding the rapid trajectory of renewable energy growth. The trends highlighted in the chart underscore the ongoing shift away from fossil fuels, a momentum that has undoubtedly continued to build throughout 2025 and into the current year.
