Abstract
Abstract The paper presents the estimation of trends describing the level of renewable energy resources in Poland and in EU-28 countries within the years 2004–2012. The process of the increase of the percentage of renewable energy in total production of energy was also presented. Comparative statistical analysis was carried out within the dynamics of the phenomena discussed in the paper with respect both to Poland and EU countries. It follows from the investigation that both in Poland and in the EU countries the increase in renewable energy resources has been observed. However, the rate of the increase of the level of renewable energy in Poland is not enough to catch up with the leading EU countries in near future.
