The Impact

The paper presents the investigation of the impact of Ignalina Nuclear Power Plant (NPP) shutdown on Lithuanian energy security. The system of energy security indicators, covering technical, economic and socio-political aspects is presented. The integral characteristic of these indicators shows the level of energy security. The paper analyses the Lithuanian energy security level in 2007. To make a comparison, the energy security level in 2010, after the shutdown of Ignalina NPP, when Lithuanian Power Plant in Elektrėnai becomes the main electricity producer, is forecasted. Two alternatives are analysed: Lithuanian Power Plant uses either gas or heavy fuel oil for electricity production. The security level of each indicator, each indicator block and the total security level are presented as the result. Energy security indicators, which increased or decreased after the shutdown of Ignalina NPP, are analysed, including the indicators which have had the greatest impact on the change in energy security level. The influence of Ignalina NPP shutdown on CO2 emissions is presented. Also, electricity generating costs for different types of electricity production at a different discount rate are presented.

In the article presented, the authors prove the objective need for the development of the electricity industry of the Republic of Crimea on the basis of the active use of the renewable energy sources, caused by the world processes of the formation of the “green” economy. The object of the study is the territory of the Republic of Crimea - a bright representative of the energy deficit region. The development of the electricity industry of the Republic of Crimea on the basis of the use of the renewable energy sources serves as the basis for ensuring regional energy security, the fragility of which was determined by the political events of 2015. The authors studied the research papers of leading domestic and foreign scientists devoted to the analysis of the renewable energy sources in order to justify the further active development of a wind energy, a solar energy as well as bioenergy and landfill gas energy in the Republic of Crimea. The development of the Republic of Crimea’s electricity industry through the use of the renewable energy sources and local fuels is an essential area of modern active regional policy. It is determined by the fact that this direction, firstly, is considered as environmentally friendly generation, and secondly, contributes to a qualitative increase in regional energy security level.

The Impact

The article examines the peculiarities of the relationship between energy security and innovation processes in the industrial region. Systemized approaches to the methodology for calculating the level of financial security have been consolidated. It is concluded that it is appropriate to use an indicative method of energy security analysis as a classic epistemological variant of the study of the energy security phenomenon. As a result of the assessment of the energy security level of the Kemerovo (Kuzbass) region it is concluded that all indicators of energy security except a certain degree of depreciation of the fixed assets of the fuel and energy complex enterprises have acceptable pre-crisis values. According to the share of own sources in the balance of electricity, the disposable capacity of power plants and the capacity of the largest power plant in Kuzbass region is in the pre-crisis zone, which determines its energy independence. It is noted that the share of coal as the dominant fuel resource in the structure of fuel consumption is at the pre-crisis level. The energy supply is emphasized to cover not only the issues of production, supply of energy resources and availability of energy sources, but also the aspects of the ecology and energy resources accounting. This determines the necessity to adjust the methodology for determining the energy security. It is proposed to supplement the methodology of assessing the level of energy security with indicators that take into account the diversification of sources of electricity generation both as a main resource and the possibility of commercial accounting of electricity consumption. The statement about the impact of the innovation level of energy on the level of region energy security and the pace of innovation process is justified.

Abstract In the age of high pace of technological, economic and social development, stable and uninterrupted energy supply is one of the key components determining the economic sovereignty of the state, its position in international relations, and the quality of human life. Every economy around the world is heavily dependent on its energy sector. Consequently, ensuring energy security is currently one of the most important determinant of every country’s national security and the purpose of its security policy. In this article we focus on Romania’s energy security internal condition and prospects. Our main goal is to present actual state and prospects of Romanian energy sector. In order to achieve that goal, we decided to use various methods, such as descriptive analysis, document analysis and comparative analysis. The article has two parts. The first part consists of a description of energy sources and infrastructure used by Romanian economy. The second part is an analysis of possible chances and threats for both energy sector and energy security level.

The paper deals with the problems of balancing the United Energy System of Ukraine caused by high renewable energy penetration and the impact of the COVID-19 pandemic on the energy sector. The paper analyses the trends in renewable energy development, the dynamics and structure of electricity consumption and export in pre-epidemic and epidemic periods and identifies the main challenges to operational security of the United Energy System of Ukraine. The methodical approach to improve the methodology for estimation of country’s energy security level by considering the index of developing capacities for balancing the United Energy System of Ukraine is suggested. In addition, proposals have been made to reduce threats to the stable work of the United Energy System of Ukraine by putting into operation of energy storage capacities, promoting the development of мaneuvering renewable energy capacities, and implementation of other appropriate measures in this field.

The Impact

Robust economic growth, increasing population and personal consumption are the main drivers for the rapid increase of energy demand in Malaysia. Increasing demand has compounded the issue of national energy security due overdependence on fossil fuel, depleting indigenous domestic conventional energy resources which in turns has increased the country’s energy import dependence. In order to improve its energy security, Malaysia has seriously embarked on a renewable energy journey. Many initiatives on renewable energy have been introduced in the past decade. These strategies have resulted in the exploding growth of renewable energy deployment in Malaysia. Therefore, this study investigated the impact of renewable energy deployment on energy security. Secondary data was used to calculate the energy security indicators. The study also compared the results of applying different energy security indicators namely Availability, Applicability, Affordability and Acceptability dimension of energy resources. The evaluation shows that Malaysia will experience improvement in Energy Security, particularly on Availability, Affordability and Acceptability dimensions of energy security. This study suggests that energy security level could be further enhance by efficient utilization of energy, reducing carbon content of energy and facilitating low-carbon industries.
