The Fukushima accident of March 2011 had great political, economic, and social impacts on Japan and marked a very important turning point in Japan’s energy policy. As the accident has also greatly exposed the vulnerability of Japan’s energy security, it is crucial to clarify the path that Japan should take to maintain and secure its energy security in case of any possible future outbreak that may threaten its energy security. For this purpose, we conducted a comprehensive and structural analysis of Japan’s energy security based on APERC’s 4As framework and by using fuzzy logic and the Fuzzy-DEMATEL method to quantitatively understand the performance of Japan’s energy security and how the Fukushima accident had impacted the performance. Our results demonstrate that Japan’s energy security has clearly degraded after experiencing Fukushima accident. In addition, the results of the structural analysis by the Fuzzy-DEMATEL method show that the most salient dimension in the 4As framework for improving Japan’s energy security is the “Availability” dimension, and for this purpose nuclear energy and renewables play very important roles in securing the future energy security in Japan; this is consistent with the current energy policy measures announced in the Strategic Energy Plan of 2014.

Dynamic Shift

AbstrakBerbagai dimensi dari konsep ketahanan energi menjadikannya topik diskusi besar di saat pandemi. Pergeseran dinamis dari ketahanan energi dapat dilihat baik dalam skala internasional maupun domestik. Makalah ini akan berfokus pada perubahan dinamis ketahanan energi di Indonesia dengan menganalisis kebijakan dan inisiatif energi di masa lalu dan saat ini sesuai dengan konsep yang dielaborasi oleh Melly Caballero. Perbandingan fokus Indonesia pada ketahanan energi sebelum dan selama wabah COVID-19 akan memberikan gambaran yang jelas tentang bagaimana Indonesia mengamankan energi. Argumen utamanya tetap bahwa Indonesia sekarang berfokus pada keamanan sebagai keterjangkauan, bukan ketersediaan dan keberlanjutan. Ini karena, peningkatan tagihan listrik rumah tangga yang dicatat PLN, berbeda dengan aktivitas industri yang menurun membuat permintaan energi nasional melonjak. Kebijakan energi yang disebutkan dalam makalah ini mengacu pada peraturan dan inisiatif pemerintah dari Perusahaan Listrik Negara (PLN). Makalah ini juga akan mengenali masalah yang sedang berlangsung tentang distribusi energi yang tidak merata di luar jaringan Jawa dan melihat bagaimana masalah ini dipengaruhi oleh pandemi. Kata Kunci:COVID-19, Keamanan Energi Indonesia, Kebijakan Energi AbstractMultiple dimensions from the concept of energy security makes it a big topic of discussion in times of a pandemic. The dynamic shift of energy security can be seen both in the international and domestic scale. This paper will focus on the dynamic shift of energy security in Indonesia by analyzing past and current energy policies and initiatives according to the concepts elaborated by Melly Caballero. A comparison of Indonesia’s focus on energy security before and during the COVID-19 outbreak will give a clear picture in how Indonesia is securing energy. The main argument remains that Indonesia is now focusing on security as affordability instead of availability and sustainability. This is because of the increased household electric bill recorded by PLN in contrast to the decreasing industrial activities. The energy policies mentioned in this paper refers government regulations and initiatives from the state-owned electric company (PLN). This paper will also recognize the ongoing issue of unequal distribution of energy outside the Java grid and see how this issue is impacted by the pandemic.  Keywords: COVID-19, Indonesia’s Energy Security, Energy Policy

This chapter reviews relevant literature on the current state and effectiveness of developing renewable energy on energy security in general, and on energy security in the European Union (EU) in particular. The chapter elaborates on primary energy import sources, possible alternatives, and how energy security is affected by the sources of supply. It also gives an analysis of the effects of the Ukrainian crisis, the isolation of Iran on diversification sources, and on European energy security. It examines EU’s energy policy, analyses the best motivation for a new energy policy direction within Europe, and suggests alternative solutions for enhanced energy supply security. The aim is to suggest suitable solutions for energy security in Europe through energy supply diversification. Supply diversification includes alternative energy corridors for reducing dependency on Russia as a supplier and enhancing the power generated by renewable energy sources under the European Union 2020 strategy.

Climate And Energy Policy

This article examines the recent changes of three central EU climate and energy policies: the revised Emissions Trading Directive (ETS); the Renewables Directive (RES); and internal energy market (IEM) policy. An increasing transference of competence to EU level institutions, and hence “vertical integration,” has taken place, most clearly in the case of the ETS. The main reasons for the differing increase in vertical integration are, first, that more member states were dissatisfied with the pre-existing system in the case of the ETS than in the two other cases. Second, the European Commission and Parliament were comparatively more united in pushing for changes in the case of the ETS. And, third, although RES and IEM policies were influenced by regional energy security concerns, they were less structurally linked to and influenced by the global climate regime than the ETS.

Electricity is one of the factors shaping the quality of life of society. The Polish energy sector is to a large extent identified with fossil fuel used in conventional energy, based mainly on hard coal, which is not fully in line with the current energy policy of the European Union. Therefore, today it is necessary to use renewable energy more efficiently, which, in addition to the clearly indicated economic effect, also accentuates environmental effects. The purpose of the work is to show the opinions of young people aged 15–24 in terms of their awareness of the interpretation of myths about renewable energy, which is a key problem in the development of the modern energy sector, and to indicate the directions of development of the energy policy in Poland.

THIS STUDY IS ONE OF COMPARATIVE STRUCTURAL ANALYSIS deliberately avoiding a sociological definition of the situation. It is assumed that two societies had existed in Czechoslovakia for some time and the difference between them, and possible analogies, are examined. There is also an assumption that the division of Czechoslovakia occurred especially because ‘Czechoslovak society’ as such had not yet been established; this was in spite of the fact that the two societies, at the time of the split, had substantially more in common than they had had at the time of Czechoslovakia's formation. There exists the view, which we want to verify, that during the decline of the federation the following factors were significant:1. The differences in economic, social, cultural and dispositional structures;2. The asynchronous and differing processes of modernization in both societies;3. The different consequences of the formation of societies of Soviet type in the Czech Lands in Slovakia;4. The differing processes for rectification of political, economic and cultural institutions in both republics after November 1989.

Access to energy resources has become one of the main challenges of energy security in the modern world. Due to the growing political instability of countries exporting energy resources, the energy security category should be perceived in a special way. Energy security is expressed, first of all, in stable access to energy resources at an acceptable price. The aim of the article is to determine to what extent the strategy of diversifying the sources of crude oil imports to Poland and Belarus is implemented in practice, and to what extent the implementation of this strategy is conducive to building energy security for both these countries. It seems that despite the similar geological and geographical conditions, as well as the common historical infrastructure heritage, Poland and Belarus shape their energy policy differently. The conducted analysis has an empirical dimension, as the REES index is used to measure the concentration of imports and the short-term risk for the security of crude oil supplies. The article shows that a properly implemented diversification strategy significantly improves the country’s energy security, which is possible due to the use of alternative directions for oil imports to the Russian one.

This chapter presents the overview of pollution; the issues of soil pollution, water pollution, and air pollution; the aspects of renewable energy; energy security and energy imports; and renewable energy policy and renewable energy policy instruments. Pollution is one of the most important environmental, social, and health issues in the world. Pollution creates many diseases and causes death of many people across the globe. The environmental damage caused by pollution can reach catastrophic proportions and destroy entire ecosystems leading to the death of many species and a big biodiversity loss. Renewable energy is a critical part of reducing global carbon emissions and the pace of investment has greatly increased as the cost of technologies fall and efficiency continues to rise. Renewable energy offers a wide variety of different options to choose from as countries can choose between sun, wind, biomass, geothermal energy, and water resources.

Europe’s economic wellbeing and growth are highly energy dependent and heavily reliant on Russian imports of oil and gas. European energy security, its alternatives, and implications are examined in this chapter with the view of sustainability and the EU-Russian energy dialog. With an asymmetric mutual political-economic interdependency with Russia, Europe’s exposure in oil and gas calls for sustainable energy solutions. Meantime, Russia, the key energy supplier in the European region, is also a major energy consumer whose economy is characterized by high energy intensity. Russian energy sector needs serious improvements in technology, investment, and management: failure to address these priorities erodes Russia’s reliability as major regional energy supplier. The chapter explores the dynamics of Russian energy sector and implications for European energy security and sustainability.
