The energy security is a subject often picked by government representatives of current times, who take actions influencing geopolitical relationship of Europe and globe. It is an important aspect because of its economical, ecological and environmental nature. Tensions between countries of Eastern Europe, legislative changes made by European Union and rapidly increasing demand in the energy sector lead players to securing their resources and its supplies, along with infrastructure. Energy Security Index (WBE) proposed by A. Sokołowski (2010) and Kościuszko Institute is an effective tool for measurement, impartial assessment and classification of analyzed economies, checking their flexibility and possibilities in the international energy arena. The index is built as multidimensional comparison analysis, which gives the prospect of creating rankings. This article presents the essence of energy security in the context of an economic potentiality in the gas sector, with the chosen elements counting into WBE and its applications. The vast aggregate is created by calculations, using worked data, to summarize assessment of energy security status of examined country. The authors tried to compare chosen elements of WBE of neighboring Polish and Ukrainian economies. As an addition, based on data availability, information is enriched by appropriate commentary. Graphics shows the essence and summary of gas transportation infrastructure in both countries and gives the idea of possibilities of cooperation between them.
The aim of the study was to identify the state of residential buildings in terms of energy consumption and modernisation in Poland against the background of the EU, and to determine factors and activities increasing households′ interest in net-zero energy buildings. In the European Union, we are observing a tendency to increase the energy efficiency of buildings, including residential, and decarbonise building stock by 2050. The objective of the undertaken activities is to reduce energy use and the negative impacts of the use of buildings on the environment. Attaining this objective requires modernising many buildings. This dissertation includes an investigation into the condition of buildings in Poland from the aspect of energy use and the kind of carriers of this energy, and also into another issue: what factors and activities may increase society′s interest in net-zero energy buildings, and in the use of energy from renewable sources in residential buildings. The studies were conducted with the use of the data provided by the Central Statistical Office and EUROSTAT, and also of the reports of the European Commission, the data of the Central Emission Register of Buildings (CERB) and the Odysse–Mure database. An important source of information was also surveys conducted with the application of CAWI (Computer-Assisted Web Interview), and also of PAPI (Paper and Pencil Interview), among 387 households in Poland. For the purpose of analysing the results of the studies, the methods of descriptive statistics, the chi-square test of independence, the ANOVA test of Kruskal–Wallis and the Mann–Whitney U-test were used. The analysis gives rise to the conclusion that, in residential buildings, household′s annual primary energy demand is dependent on the year in which a building was commissioned. Newer buildings can boast smaller heat energy use. Simultaneously, ever more households are undertaking activities that will result in the thermal modernisation of residential buildings. The studies have shown that the development of net-zero energy buildings requires undertaking activities in the scope of introducing allowances and subsidies, and also increasing social awareness in the scope of this kind of building. Interest in buildings using solely renewable energy sources is contributed to by raising energy prices, and also the falling prices of required installations.
Purpose:The aim of this paper is to compare (also to EU27) and analyze chosen aspects of Energy sectors, which are currently indispensable for the appropriate functioning of an economy. Based on the literature review, a research gap was identified in the form of a lack of studies related to the current situation of the use of renewable energy sources in the total energy supply of the Visegrad Group countries. Additionally, the comparison of the situation in question for the V4 countries is an extremely important issue because of the possibilities of cooperation in this area. Approach/Methodology/Design: The undertaken research issues and the set goal determined the choice of research methods, such as critical literature review, statistical methods, analysis and synthesis methods. Findings: The most important conclusions from the conducted analyses indicate the necessity to prepare and implement the decarbonization process, especially in Poland. Practical Implications: V4 countries should take joint actions to increase share of renewable energy sources in total energy supply in order to 1) reduce negative emission and air pollution 2) tackle EU standards and goals set for RES share in Energy mix 3) increase in Energy independency and security of V4 members and group as a whole. Originality/Value: The originality and value of the study results from the fact that the current comparison of the V4 countries in terms of the use of renewable energy sources and its structure does not exist in the available literature. It should be noted that this is an important aspect of the energy policy of modern countries.
The purpose of conducted research was to recognize factors determining households’ Energy transition and barriers that slow that process. Energy transition itself, understood as a shift in the structure of fuels used in energy production and technological changes related to its use, are key elements of shaping the economy. It was determined to what extent existing household renewable energy installations meet the energy needs of their residents and what factors encourage their installation. In addition, barriers limiting energy transition as perceived by household members were identified. The research used data from the EUROSTAT and the results of surveys conducted using the CAWI (Computer-Assisted Web Interview) and PAPI (Paper and Pencil Interview) techniques among households in Poland. The methods of descriptive statistics, the chi-square test of independence, the Kruskal–Wallis ANOVA test, the Mann–Whitney U test and logistic regression were used to analyze the research results. The analyses show that fossil fuels dominate in energy production in Poland. The share of renewable energy sources in the gross final energy consumption in 2020 was 16.1%. Their structure is dominated by photovoltaic installations with a share of 52%. Further increase in energy prices and fears of interruptions in energy supplies will favor the further increase in the number of installations for renewable energy sources. According to the respondents, the energy efficiency has a significant impact on the quality of life and environment, but the main barriers to its development include financial constraints of households.
