Struktura oraz dynamika produkcji energii odnawialnej w państwach UE

The aim of the paper is to estimate the dynamics of renewable energy and its structure in European Union countries, with special regard of Poland. The method applied was chosen out of comparative procedures and it was the di-vision of objects arranged in linear order into a certain number of subsets. Then, the measure of the degree of resemblance of rankings of these objects was proposed. The position of Poland in the context of production of renewable energy in EU countries was discussed with the focus on its weaknesses.
