Wind conditions across many parts of Europe were below average during the first half of 2025, according to IREC indexes. Several regions, including Germany, Austria, Belgium, the Netherlands, southern England, Italy and multiple offshore areas, experienced their least windy start to the year in 15 years.
These low wind levels have affected electricity generation from wind power, with estimated production revenue down by 10% to 20% in almost half of the European areas analysed. Some regions recorded even larger decreases. In contrast, wind conditions in parts of Scandinavia were slightly above the long-term average, standing out as an exception to the general trend.
