Clean energy surge continues

The world added a record amount of renewable power capacity in 2025, driven by rapid solar and wind installations across China, Europe, and the United States. New figures show renewables now account for the majority of new electricity generation worldwide. Falling equipment costs and supportive policies helped speed deployment, particularly in utility-scale solar.

However, the surge is straining power grids not designed for variable energy flows. Utilities are racing to upgrade transmission lines, storage, and digital controls to manage peaks and prevent outages. Experts say grid investment must accelerate to keep pace with clean energy growth.

Balancing speed and stability

Energy planners warn that delays in grid expansion could slow future projects. Batteries and demand-response programs are becoming essential tools to smooth supply. Governments are also encouraging cross-border interconnections to share power during shortages.

Despite challenges, analysts remain optimistic. They argue that renewables are now the cheapest option in many regions and will continue to attract capital. The next phase of the energy transition will depend on infrastructure, not technology alone.
