Cloudy weather dampens European solar output and pushes power prices up

Europe faces its first major prolonged period of cloudy and windless weather of the year, dampening the continent solar energy boom and causing power prices to surge, Euronews reported. The weather conditions are throttling both solar and wind power generation. This situation is forcing the electricity grid to rely on polluting back-up power sources. [1]

Solar energy remains one of the fastest to install and cheapest forms of power in the world, according to Euronews. In optimal conditions, generating one unit of electricity through solar panels can cost as little as 0.024 euros, which performs far better than coal, gas, and wind generation. [1]

The expansion of solar infrastructure has already saved the European Union 42.9 billion euros in avoided gas imports since the start of the war on Iran, Euronews reported. Global market disruptions caused by the war on Iran previously drove electricity costs higher in other regions, including the Philippines, where residential bills surged in Manila, as FTMQ News reported earlier.

The current weather phenomenon, known as a dunkelflaute, highlights the vulnerability of renewable energy production when extended cloud cover and low wind speeds coincide. Grids must continue to balance supply by turning to secondary energy sources to meet demands while solar production stays severely reduced. [1]
