Renewable energy sources accounted for nearly half of the world’s electricity capacity in 2025, driven largely by a surge in solar power installations. The rapid expansion reflects global efforts to transition towards cleaner and more sustainable energy systems.

Solar energy has emerged as the dominant force behind this growth, supported by falling costs, technological advancements, and strong policy backing in many countries. Governments and private investors have increasingly prioritised solar projects to reduce carbon emissions and enhance energy security.

Wind energy and other renewable sources have also contributed significantly, but solar remains the fastest-growing segment. The shift towards renewables is seen as a critical step in combating climate change and meeting international climate targets.

Experts note that continued investment in grid infrastructure, energy storage, and innovation will be essential to sustain this momentum. As countries accelerate their energy transition, renewables are expected to play an even larger role in the global power mix in the coming years.
