Energy poverty is a problem that affects all member states of the European Union to a varying degree, including Poland, where about 9% of the population is at risk of energy poverty. The article aims to show the changes in energy poverty in Poland in 2010–2018. The specific goal, however, is to evaluate government measures aimed at reducing energy poverty through investments based on renewable energy sources. To present changes in the level of energy poverty in 2010–2018, the authors proposed a new synthetic measure that unifies several different measures used by researchers and allows for a comprehensive assessment of this phenomenon. The conducted research showed that in 2010–2018 there was a slow but visible decrease in the level of energy poverty in Poland. In addition, the article indicates investments in renewable energy sources that may have a positive impact on reducing the scale of energy poverty in Poland. The programs implemented with national and EU public funds, which finance investments in renewable energy sources in Poland, are also presented.

The current energy prices do not include the environmental, social, and economic short and long-term external effects. There is a gap in the literature on the decision-making model for the energy transition. True Cost Accounting (TCA) is an accounting management model supporting the decision-making process. This study investigates the challenges and explores how big data, AI, or blockchain could ease the TCA calculation and indirectly contribute to the transition towards more sustainable energy production. The research question addressed is: How can IT help TCA applications in the energy sector in Europe? The study uses qualitative interpretive methodology and is performed in the Netherlands, Germany, and Poland. The findings indicate the technical feasibilities of a big data infrastructure to cope with TCA challenges. The study contributes to the literature by identifying the challenges in TCA application for energy production, showing the readiness potential for big data, AI, and blockchain to tackle them, revealing the need for cooperation between accounting and technical disciplines to enable the energy transition.

Organic farming is one of the basic elements of constant and sustainable development of rural areas. It is the highest form of protection of the natural environment in the field of agriculture. The aim of the article is to present the development of organic farming in Poland, which became particularly important after joining the European Union. Poland strives to increase this type of production, the more so because it has considerable predispositions and favourable conditions. Organic farming in Poland shows quite large regional variations, resulting largely from natural conditions. The largest number of organic farms in 2016 occurred in the Warmińsko-Mazurskie and Podlaskie Voivodeships, and the smallest in the Opolskie and Śląskie Voivodships. The analysis uses data from the Central Statistical Office (GUS) and the Main Inspectorate of Agricultural and Food Quality (GIJHARS).

The main aim of the article was to examine the relationship between food waste and variables describing the socio-demographic characteristics of households in Poland, including reference to the prosumer behaviour of households. Do we respect food more if we produce it ourselves? That is the research question the authors have asked themselves. Consumer behaviour related to running a household, including the production of food for own needs and food waste by end consumers, is an interesting research area, especially in this combination. Food prosumption, alongside the issue of food waste, is part of new consumer trends that are an element of sustainable development. In order to explore the issue, our study was conducted using the diagnostic survey method with the CAWI (Computer-Assisted Web Interview) survey technique. The survey was conducted in July 2022 among 1112 respondents. This is a representative population of households in Poland (in terms of gender, age, size of place of residence, and education), with non-random quota sampling. The answers to the questions received were analysed with a chi-square correlation, supported by the Yule effect (φ) and Cramer’s coefficient (V). The correlations, significant though weak, showed a link between food waste and the variables of age, number of children, and number of people in the household. In addition, the majority of respondents believe that food prosumption contributes to reducing food waste within the household where food is produced for own needs.

Celem artykułu jest ocena zjawiska ubóstwa w Polsce na tle innych krajów Unii Europejskiej oraz scharakteryzowanie wybranych form przezwyciężania ubóstwa w kontekście zrównoważonego rozwoju. W artykule dokonano przeglądu literatury z tego obszaru oraz analizy źródeł wtórnych pochodzących z Głównego Urzędu Statystycznego i EUROSTAT. Ubóstwo jest zjawiskiem powszechnym i występuje we wszystkich krajach Unii Europejskiej. Około 17% obywateli Unii Europejskiej jest zagrożonych ubóstwem. Problem ten powinien być rozwiązany ze względu na zrównoważony i trwały rozwój i jest to podstawą europejskiej strategii walki z ubóstwem i wykluczeniem społecznym.

The subject of research is a phenomenon of prosumption, i.e., the intertwining of consumption and production processes, until the differences between them are blurred. When consumers produce goods and services for their use, they become prosumers. The article aimed to assess consumer behavior in terms of various forms of prosumer activity on the market of household-related services. The types of prosumer activity of rural households and their size were determined during the analyses. The article uses primary sources from a survey conducted among residents of rural areas of the Masovian Voivodeship in Poland in 2017. Statistical, descriptive, and comparative methods were used. The research shows that consumers are very active in the field of prosumption, rationally running their households. The study used principal component analysis (PCA) and selected descriptive statistics. The research results showed that the services performed can be grouped into three categories, i.e., the index of basic living self-sufficiency of households, the index of renovation and repair self-sufficiency, and the index of professional self-sufficiency of farms. Consumers usually prepare meals at home and clean, iron, and wash clothes, thus reducing the costs of running a household. It is also popular to carry out repairs oneself or to carry out repairs of equipment at home.
