Analysis of the theoretical and methodological support of the study of energy security of the country

World energy consumption is constantly growing. In these conditions, the problem of finding new opportunities to meet the growing needs in energy resources is becoming more acute. This situation leads to the need to consider the directions and prospects for development of synthetic liquid motor fuel in the context of solving the problem of enhancing the country's energy security. The object of this research is the energy security of the country and its components that characterize the internal and external factors of the functioning of the country's energy system. The components of the country's energy security are fuel and energy resources and the economic and infrastructural elements of the energy system are developed on its territory. One of the main problem areas of the research object is the lack of a unified approach to the interpretation of the essence of the concept of "energy security" and the organization of its assessment process. During the research methods of analysis, synthesis and system analysis were used. A systematic analysis of the components of energy security has proved that the generally accepted view is the inclusion of "energy accessibility" to the content of the concept of "energy security". Other components are complementary to this component. Energy security is a generalizing concept of various components and components that can’t be characterized by a single indicator. The lack of consensus on the content of this concept leads to a variety of methodological approaches to its evaluation. It is established that most often for the assessment of energy security a system of indicators is used, distributed by components and aggregated in a weighted standardized form into a single integrated indicator, which is the measure of energy security. It is proved that most of the existing methods provide for the allocation and assessment of individual components of energy security, but not enough attention is paid to assessing its market component. It is substantiated that the basis of the market approach to the assessment of the country's energy security should be an analysis of the market situation of individual energy resources with the aim of determining the reliability and balance of the provision of energy needs.
