An unsustainable energy mix and energy overconsumption contribute to negative processes such as environmental pressure or energy dependency. The aim of the article is to assess the European Union countries situation in terms of sustainable energy consumption. Eurostat was were used in the analyses. The research was based on synthetic indicators for 2017 data. A non-standard method was used. In accordance with the assumptions of sustainable energy consumption, six indicators were proposed: primary energy consumption (2005=100), final energy consumption (2005=100), share of renewable energy in energy consumption, deficit/surplus in the 2020 renewable energy sources consumption target, energy import dependency (%), greenhouse gas emissions intensity of energy consumption (2000=100). The share of renewable energy in energy consumption and deficit/ surplus in the 2020 renewable energy sources consumption target are stimulants, other features are destimulants. The European Union countries were classified into four groups due to the situation in terms of sustainable energy consumption (first class – favorable situation, second class – quite favorable situation, third class – rather unfavorable situation, fourth class – unfavorable situation). According to the results in twelve countries the situation was identified as favorable or quite favorable, while in the other sixteen countries as rather unfavorable and unfavorable. However, all countries have entered the path of necessary changes. It is important to continue monitoring and analyzing the progress of European Union countries in the field of energy and climate policy.

The aim of the research is to assess and discuss the diversity of energy production and consumption in European Union countries. The time scope covers the years 2007 and 2016. The diversity of EU countries was examined using the cluster analysis. The following diagnostic features were adopted for the analysis: energy dependency rate (in %), gross inland consumption of energy per 10,000 inhabitants (toe/10,000 inhabitants), primary production of energy (all products) per 10,000 inhabitants (toe/10,000 inhabitants), primary production of renewable energies per 10,000 inhabitants (toe/10,000 inhabitants), primary production of energy (without renewable energy) per 10,000 inhabitants (toe/10,000 inhabitants). Comparing the included indicators from 2016 to 2007 for all EU countries, an increase was recorded only for the primary production of renewable energies per 10,000 inhabitants,. Based on the cluster analysis, the examined countries were divided into six groups. According to the results of the research carried out, Northern and Eastern European countries are characterized by low energy dependence. However, according to the analysis carried out, this dependence is guaranteed based on various energy sources. The Scandinavian countries (Sweden, Finland) owe their high independence to the production of large amounts of energy from renewable sources. On the other hand, countries such as the Netherlands, Denmark, Estonia and the whole of Eastern Europe are based on primary energy sources such as: coal, oil and gas. Southern Europe countries (Greece, Spain, Italy, Portugal, Cyprus, Malta) are characterized by high energy dependence, as evidenced by low rates in the area of energy production, both in total and renewable and non-renewable energy production.
