Our paper is dealing with the issues of energy security and economic development. Our focus is on the changes and challenges that are posed in front of the many countries with regard to the threat of the shortages of energy sources and the depletion of the existing carbon sources. Economic, social and demographic changes in the world call for the novel solutions that would include innovative ways how to secure the smooth and undisrupted flow of energy for maintaining the daily lives of the citizens. We are particularly interested in showing how the integration of energy systems or the coordination between neighboring energy systems might contribute to the sustainable development and operation of the energy sector. The paper uses an example of hydro energy storage in order to show the shortcomings of the battery energy storage and the ways how it can be solved. Our results and findings show that renewable energy sources might become a viable solution to the problems specified above. Well-balanced and well-placed usage of renewables might cushion the shortcomings of the traditional energy systems and prevent major shocks to the energy security through the world and in the European Union countries.

The relevance of this article is based on the aim to fulfill the lack of understanding of public perception on energy security. Despite the fact that energy security problems in Lithuania are analyzed on a regular basis, however, there is no comprehensive research on the very issue of the public perception of energy security. The results of the empirical survey (public poll carried out in 2013) are used to explain the public perception of energy security and its main aspects, and to show the existing difference of society opinion between different social groups in regard to gender, age, education, occupation, income and living area. The research showed that variety of different aspects are taken into account in public perception on energy security. The dominance of “The prices of energy resources” (mean – 4.35) and “Reliability of energy supply services” (mean – 4.25) was fixated throughout different social groups. The three most ambivalently ranked aspects were “Development of oil extraction” (mean – 3.50), “Development of nuclear energy” (mean – 3.30) and “Development of shale gas extraction” (mean – 3.08).

The paper gives an analysis of changes in the refinery business ownership structure in two “new” EU members: Poland and Croatia, after their shift to market based economy. The key area of analysis refers to the state control over refinery assets as a tool of national energy security. Refinery sectors in both countries are presented focusing on their respective strengths and weaknesses. Changes in ownership structure of three major players: INA, LOTOS and PKN ORLEN are reviewed in order to establish how they affected sustainability and development of these entities. The paper takes into account not only the interests of Poland and Croatia, but also refers to Hungary, Czech Republic and Lithuania. The analysis was performed with regards to the general trends and expectations in the European refinery sector. Our conclusions indicate that state control over key refinery assets represent a valuable tool for energy policy and, in cases when lost, it has to be compensated by other measures. If refining capacity is left unchecked and uncontrolled energy security of the country is easily threatened. This situation often leads to an almost paradoxical situation where the energy security of individual EU member countries can easily be in conflict with the overall EU energy security policy and guidelines.
