A single wind turbine or a single PV module obviously provides only variable amounts of electricity. However, this is not the case for many PV modules and wind turbines spread across the entire continent. Wind and PV complement each other very well in Europe because of regular weather fronts; when there is little wind, there is more sunshine.

In Europe, the average weekly electricity generation in 2025 was 14.0 TWh, and no week fell below 10.2 TWh. In 2026, the average output was about 15.5 TWh, and so far, no week has fallen below 12.5 TWh.

Of course, batteries are needed for short-term storage, but with the creation of excess capacity in wind and solar power, the troughs below the load curve become narrower and shallower, drastically reducing the need for storage.
