The primary aim of this study was to assess the investment activity of basic local government units in the development of renewable energy sources co-financed by EU funds depending on CO2 emissions and other socio-economic conditions in terms of regions of Poland in the years 2007–2020. Empirical studies aimed at the verification of the research hypothesis that "the greatest investment activity in local projects co-financed from EU funds related to the development of renewable energy sources is observed for local government units in regions with highest CO2 emissions". Empirical studies were conducted based on data from the Ministry of Investment and Economic Development in Poland, the Local Data Bank, and the National Centre for Emissions Management. Thus, the conducted analyses provide both cognitive and applicatory values for the establishment of an appropriate energy transition policy in individual regions of Poland, which may be implemented by local government authorities within the current financial framework. Data concerning CO2 emissions at the regional level were estimated by applying the original disaggregation method as modified by the authors, which made it possible to fill the research gap resulting from the lack of data on emissions at the regional level. In order to show the regional diversification in investment activity of local government units in terms of renewable energy sources, its multi-faceted analysis was conducted by applying the Ward method. Clusters of regions with similar investment activity of local government units were described based on characteristics included in the typological classification (so-called active characteristics) and selected indexes showing CO2 emission levels, as well as selected socio-economic indexes (so-called passive characteristics). Based on the empirical studies, the research hypothesis presented in this paper was negatively verified. Considering both multiannual financial frameworks, the EU financial support for the development of renewable energy sources was used primarily by local government units of a predominantly agricultural character, and less advanced in terms of their development but exhibiting conditions conducive to renewable energy development.

The public procurement system in Poland remains highly centralized, although thanks to European Community directives, it is part of European law. Therefore, it has established procedures for sustainable public procurement, including so-called green public procurement. In addition to the Public Procurement Law of 11 September 2019, other provisions introducing specific instruments (e.g., energy labels, environmental labels) should be taken into consideration, as such provisions make it easier for contracting authorities to take environmental aspects into account in tender procedures. Bearing in mind the existing legal regulations, this article features a diagnosis of the degree of use of measures to improve energy efficiency in public procurement procedures and models activities related to improving this situation. For this purpose, surveys were conducted for 120 entities applying the provisions of the Public Procurement Law. Taking into consideration the results obtained in the survey, 15 factors related to the improvement of energy efficiency in tender procedures were selected with the help of 12 purposively selected experts connected with the issues raised in this article. Thanks to their expert knowledge, three key factors determining the wider use of this instrument were modeled by means of the systems theory–based methodology of network thinking. The paper also attempts to indicate the key factors determining the wider use of this instrument, using the network thinking methodology for this purpose. As a result of the conducted research, it was found that these factors include human capital, industry, and the energy crisis. Research on the subject in the Polish literature remains innovative and allows for the formulation of application recommendations for decision makers. The concept of energy efficiency in this paper refers to the ratio of the results obtained to the energy input. Efficient use of energy aims to reduce the amount of energy needed to deliver products and services. [ABSTRACT FROM AUTHOR]

This paper introduces the utilization of the International Atomic Energy Agency's toolkit for reactor technology assessment (RTA) application to deploy small modular reactors (SMRs) in the Czech Republic, Egypt, and Poland. The increasing demand for clean energy has led to the prominence of small modular reactors (SMRs) in addressing global energy challenges. The successful integration of SMRs into national energy systems necessitates comprehensive evaluations that take into account each country's specific characteristics and energy requirements. RTA application represents significant progress towards innovative nuclear solutions, advancing a cleaner and more resilient energy future plan. The aim of this study is assessing the feasibility and advantages of SMR implementation in these countries, focusing on energy security, emission reduction, and long-term sustainability. Various SMR technologies, including NuScale, SMART, HTR-PM, BWRX-300, SMR-160, and RITM-200, are comparatively analyzed based on safety, scalability, efficiency, and economic viability. The findings reveal that BWRX-300 suits the needs of the Czech Republic and Poland, while RITM-200 is the optimal choice for Egypt. Moreover, NuScale also stands as a strong alternative for all three countries. This article emphasizes the importance of informed discussions and evidence-based decisions, promoting sustainable energy development and global advancements in nuclear technology. By utilizing SMRs, the Czech Republic, Egypt, and Poland can enhance energy security, reduce emissions, and meet rising energy needs sustainably. [ABSTRACT FROM AUTHOR]

The present paper deals with issues related to activities undertaken by local government. The article focuses on the identification and assessment of the significance of local government's different bottom-up initiatives that support development of local entrepreneurship. The article also indirectly discusses the importance of activities referring to energy efficiency. Through the digitization process and by using digital tools, LGs realize projects, improve local actors' awareness, and finally achieve new challenges such as a higher proportion of gross final energy consumption being from renewable sources. The aim of the paper is to present the relationship between the LGs' entrepreneurial activities, which we call bottom-up initiatives, and the local entrepreneurship level, understood as the number of entrepreneurs active on the territory of a LG. This paper presents the results of research carried out on the bottom-up initiatives undertaken by Polish local governments to support entrepreneurship. The research was based on survey and statistical tools and stepwise regression analysis. In the paper, bottom-up initiatives undertaken by local governments (such as organizing events at the national or regional scale that enable networking among entrepreneurs or establishing departments for supporting local entrepreneurship that offer cooperation with local entrepreneurs) were found to influence the number of entrepreneurs active in local government territories. The paper concludes that local governments and their bottom-up activities are an important factor influencing local entrepreneurship development. The presented research results have implications for policy makers and may be useful for local governments in Poland and in other countries in the context of supporting entrepreneurship by undertaking bottom-up initiatives at the local level.
