The principal component analysis of the West European wind power production is worked out and presented. The overall production in 15 countries in Western Europe is highly correlated and it is shown that the sum-production is dominated by a number of principal components far less than the number of countries. This manifests the correlation of wind power production in the larger area such as Western Europe.
