As energy transition accelerates and transition politics intensifies, the strategy and pathway of energy transition are becoming an issue. And there is a growing interest in energy democracy as a discourse criticizing market-led energy transition and seeking fundamental restructuring of energy system. However, the imaginations of energy democracy are different from each other as a social movement discourse and a criterion for political evaluation of energy transition. This study aims to analyze the issues of energy democracy and reinterpret them from the perspective of the Commons. As various social movements are connected, energy democracy includes elements of localization, decentralization, liberalization, commoning and socialization that can conflict with each other in terms of transition strategy. In addition, the imagination of the subject of energy transition is diverging between investors, consumers, workers, and energy citizens. Thinking about energy infrastructure as the Commons in this situation helps to understand the critical issues of energy democracy and to imagine new transition experiments. Energy democracy implies that the new commons are being created across the scale of energy infrastructure in the contention of the transition to a decentralized renewable energy system.

User preferences and ratings may be anticipated by recommendation systems, which are widely used in social networking, online shopping, healthcare, and even energy efficiency. Constructing trustworthy recommender systems for various applications, requires the analysis and mining of vast quantities of user data, including demographics. This study focuses on holding elections with vague voter and candidate preferences. Collaborative user ratings are used by filtering algorithms to provide suggestions. To avoid information overload, consumers are directed towards items that they are more likely to prefer based on the profile data used by recommender systems. Better interactions between governments, residents, and businesses may result from studies on recommender systems that facilitate the use of e-government services. To broaden people's access to the democratic process, the concept of "e-democracy" applies new media technologies. This study provides a framework for an electronic voting advisory system that uses machine learning.

The pressing need to mitigate greenhouse gas emissions has stimulated a renewed interest in nuclear energy worldwide. However, while numerous countries have shown interest in nuclear power over the course of history, many of them have not continued their pursuit and chosen to defer or abandon their peaceful nuclear power projects. Scrapping a national nuclear power program after making initial efforts implies significant challenges in such a course or a waste of national resources. Therefore, this study aims to identify the crucial factors that influence a country's decision to terminate or hold off its peaceful nuclear power programs. Our empirical analyses demonstrate that major nuclear accidents and leadership changes are significant factors that lead countries to terminate or defer their nuclear power programs. Additionally, we highlight that domestic politics (democracy), lack of military alliance with major nuclear suppliers, low electricity demand, and national energy security environments (energy import, crude oil price) can hamper a country's possibility of regaining interest in a nuclear power program after it has been scrapped, suspended, or deferred. The findings of this study have significant implications for policymakers and stakeholders in the energy sector as they strive to balance the competing demands of energy security, and environmental sustainability.

Public acceptance is a major issue that will determine the future of nuclear energy. In this article, we review relevant studies and identify several common patterns of nuclear public acceptance. Based on these patterns and four categories of factors, we propose hypotheses on the impact of different socioeconomic factors on the public opinion of nuclear energy. These factors were demographic and social influences, politico-economic, energy conditions, and nuclear accidents and natural risks. We tested these hypotheses using a data set including survey results on public opinion of nuclear energy in 59 countries from 1987 to 2014. Results of the regression analysis generally verified the proposed hypotheses, especially regarding the positive impact of education or geological suitability and the negative effect of improved living standards and democracy on nuclear acceptance. We propose policy recommendations, including a better focus on education and communication and a thorough consideration of the social and geological conditions a country needs to make before deciding to go nuclear. Potential weaknesses of this study are also discussed, including the possible causal relation between independent variables and the binary nature of the dependent variable.

The core of the block chain technology is solving the problem of agreement on double payment, and the PoW, PoS and DPoS algorithms used for this have been studied. PoW in-process proofs are consensus systems that require feasible efforts to prevent minor or malicious use of computing capabilities, such as sending spam e-mail or initiating denial of service (DoS) attacks. The proof of the PoS is made to solve the Nothing at stake problem as well as the energy waste of the proof of work (PoW) algorithm, and the decision of the sum of each node is decided according to the amount of money, not the calculation ability. DPoS is that a small number of authorized users maintain a trade consensus through a distributed network, whereas DPS provides consent authority to a small number of representatives, whereas PoS has consent authority to all users. If PoS is direct democracy, DPoS is indirect democracy. This study aims to contribute to the continuous development of the related field through the study of the algorithm of the block chain agreement.

World Wide Views on Climate and Energy held on 6 June 2015 was a structured citizens' deliberative consultation forum involving 10,000 citizens in 77 countries, and South Korea was one of the participating countries. Citizen participants, selected to reflect the demographic diversity in their countries or regions, were given information beforehand and deliberated for a full day with other citizens and voted on an identical set of questions, designed to reflect policy controversies at the UN COP negotiations to be held in Paris on December 2015. This study, firstly, analyzes the backgrounds and purposes of World Wide Views on Climate and Energy and reports the WWViews event held in Seoul, Korea before examining the theoretical implication of it. And then, this study discusses about the features and opportunities of World Wide Views on Climate and Energy as a way of forming a global deliberative governance by focusing on deliberative democracy, citizen participatory governance, and global citizenship.
