The electricity production sector has a significant share of final energy consumption and has a huge potential to use more renewable energy sources. Over the last two decades, the European Union (EU) reform of electricity markets has had positive results, and market liberalization acts as a stimulus for energy efficiency, lower prices, and technological progress. Today&rsquo ; s EU policy for the development of electricity and the entire energy sector seeks to provide system modernization, stability, reinforcement of the single market, and implementation of climate change policy with an emphasis on the decarbonization of energy sources and the increase of energy efficiency. After all of the EU efforts to form an electricity sector in member states, it is necessary to assess the efficiency of the policy implemented and to identify the results achieved in shaping a sustainable electricity sector. The purpose of this article is to carry out a sustainability assessment of the electricity sector in the EU countries. A set of eight indicators designed to assess the sustainability of the electricity sector of different EU countries in 2017 has been drawn up. The assessment is made using the multi-criteria decision-making method (MCDM) Technique for Order Preference (TOPSIS). The assessment shows that the electricity market of Slovenia is the most sustainable, with Luxembourg in the second position in the EU.

The effects of the global COVID-19 pandemic on the energy sector and the economy as a whole are being followed by the global energy crisis, which has been exacerbated by the war in Ukraine. The situation is particularly difficult for European countries, which are heavily dependent on imported energy from Russia. In the face of such economic uncertainty, it is necessary to analyze and assess the energy poverty situation in the region. The article overviews the extent of energy poverty among European Union (EU) countries and determines regional differences by comparing the situation, trends and policy measures applied, followed by the challenges and opportunities to combat energy poverty among households during the global COVID-19 crisis and economic uncertainty. A scientific literature review was performed and the effect of the COVID-19 pandemic on the energy poverty of households was identified. Moreover, a set of indicators reflecting the extent of energy poverty in different EU countries has been developed and an analysis of indicators was performed by comparing the situation, trends and policy measures applied.

In order to control the COVID-19 pandemic, the governments of the world started to implement measures regarding social distance and social contacts, including closures of cities, work and study relocations, and work suspension. The epidemical situation and the lockdown of the economy by governments in various countries caused changes in production, changes in the habits of energy consumers and other energy-related changes. This article analyses the impact of the global pandemic on the energy sector and the relationship with the progress to the sustainability of the energy sector. The systematic literature review was performed in the Web of Science (WoS) database. The research follows recommendations of the SALSA (Search, Appraisal, Synthesis and Analysis) and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approaches. A total of 113 relevant articles were selected for the analysis. All selected articles were categorized according to their application and impact areas. The five main impact areas of the COVID-19 pandemic to the sustainability of the energy sector were identified: consumption and energy demand ; air pollution ; investments in renewable energy ; energy poverty ; and energy system flexibility. Based on the current research findings and perception of the problem, the main insights for future research in the field are provided.

Different power generation technologies have different advantages and disadvantages. However, if compared to traditional energy sources, renewable energy sources provide a possibility to solve the climate change and economic decarbonization issues that are so relevant today. Therefore, the analysis and evaluation of renewable energy technologies has been receiving increasing attention in the politics of different countries and the scientific literature. The household sector consumes almost one third of all energy produced, thus studies on the evaluation of renewable energy production technologies in households are very important. This article reviews the scientific literature that have used multiple-criteria decision-making (MCDM) methods as a key tool to evaluate renewable energy technologies in households. The findings of the conducted research are categorized according to the objectives pursued and the criteria on which the evaluation was based are discussed. The article also provides an overview and in-depth analysis of MCDM methods and distinguishes the main advantages and disadvantages of using them to evaluate technologies in households.

The European Union (EU) has set ambitious goals for climate change and energy in its pursued policies (20% of renewable energy until 2020, 27% until 2030, and the aim to become the global leader in energy produced by renewable energy sources). Even more ambitious goals are established in the strategy of Energy 2050. Today European energy policy is oriented towards energy security, expansion of energy markets, energy efficiency, decarbonisation, and scientific research and innovations.

The penetration of renewable energy is one of the main challenges for sustainable energy development. Local governments across the European Union commit to development and implementation of the Sustainable Energy (and Climate) Action Plan. This paper focuses on the case of Lithuania—a Central and Eastern European country. Almost one-third of Lithuanian municipalities have joined the Covenant of Mayors and prepared the plans that include SWOT analysis. However, there is a lack of information on how those plans contribute to climate change mitigation and sustainable energy development. This study identifies the links between key policy financial instruments, increasing energy efficiency. The Strategic Action Plans aimed at reducing GHG emissions and energy consumption in Lithuanian municipalities are analyzed. The challenges in promoting the renewable energy generation in Lithuanian rural regions are discussed. Moreover, the importance of strengths, weaknesses, opportunities, and threats identified is elicited at the local level. The study uses a combination of methods, such as expert surveys and SWOT analysis, that complements the tools used for regional energy climate planning and allows for overarching analysis. The expert survey shows that priority is given for renovation of buildings and modernization of energy infrastructure, making them more sustainable and more energy efficient. The results also show that, in the case of Lithuania (and possibly elsewhere in the post-Soviet countries), conditions and opportunities should be created beforehand to increase energy efficiency. Once this is achieved, the policies should focus on energy transition by switching to sustainable energy resources.
