The global energy transition continues in 2025 with the launch of over 12 gigawatts (GW) of nuclear capacity under construction, as indicated by the latest report from the International Energy Agency (IEA) released on April 20, 2026.
This movement reflects a renewed interest in nuclear energy, seen as a controllable and low-carbon energy source in a context of increased energy security.
At the same time, renewable energies confirm their rise in power. Installed capacities reached a record level, with nearly 800 GW added in a single year. Solar photovoltaic power dominates this dynamic, representing around 75% of new installations, followed by wind power. Battery storage, in strong growth, is becoming a strategic complement to stabilize electrical networks.
An increasingly decarbonized energy growth
The year 2025 is marked by a notable evolution in electricity production. Renewables and nuclear power together provided approximately 600 terawatt-hours (TWh) more, the largest increase ever recorded. This progress helped cover most of the global electricity demand growth, thereby reducing the reliance on fossil fuels.
In this context, global coal demand only increased marginally, by about 0.4%, indicating a slowdown in its trend. However, this stability masks regional disparities linked to climatic conditions and fluctuations in natural gas prices.
