摘要：This article provides an overview of the structure and utilization of the new EU member states (EU-13) energy consumption. During the analysis, it was determined which non-renewable energy carriers were replaced by renewables ones. The replacement of energy sources with each other was analyzed by means of a correlation matrix. Results indicated that coal was replaced by renewable energies in Poland, Czech Republic, Slovakia, Bulgaria and Cyprus. Furthermore, the renewables basically replaced oil in Malta and gas was replaced by renewables in Lithuania. In other countries the relation between renewables and non-renewables could not be detected. The structure of energy production in the EU countries were different due to the differences of natural endowments. The main goal of the European Union energy policy is to reduce the CO2 emission by decreasing the fossil fuel consumption and this finding new ways to replace traditional energy sources is of utmost importance.
