This paper summarizes the arguments and counterarguments within the scientific discussion on the impact of energy-efficient development on promoting the national green brand. The primary purpose of the research is to provide an overview of the scientific background devoted to the relationship between the energy efficiency policy and the country’s green brand to identify the potential research gaps and highlight the prospects for particular research directions. The systematization of scientific publications presented in the Scopus database showed a rapid tendency for publication activity on the investigated theme from 2000 to 2020. However, there has remained a deficiency in investigating the role of energy efficiency policy in formulating the country’s green brand. Therefore, it is appropriate to screen out the relevant publications to detect the future research directions in boosting energy efficiency for strengthening Ukraine’s green brand. To obtain the objectives of this study, the paper is presented in the following logical sequence: determining the keywords to find the relevant publications; searching the publications; conducting the evaluation analysis by specific metrics; applying the bibliometric analysis for the investigation of keywords and their co-occurrence. The co-occurrence analysis was performed using the VOSviewer software tools. The study sample consists of 3090 publications indexed in the Scopus database. The study involved documents published from 2000 to 2020. The research identified the most productive authors, prestigious scientific journals, and the most contributing countries and institutions. The publications were clustered into five thematic groups, which indicate the main research directions. The authors specified the prosperous lines for future research.

W artykule podsumowano argumenty i kontrargumenty w dyskusji naukowej na temat wpływu efektywnego energetycznie rozwoju na promocję narodowej zielonej marki. Podstawowym celem badania było dokonanie przeglądu polegającego na określeniu relacji między polityką związaną z efektywnością energetyczną a zieloną marką kraju w celu zidentyfikowania potencjalnych luk badawczych i naświetlenia perspektyw dla poszczególnych kierunków badawczych. Systematyzacja publikacji naukowych zebranych w bazie Scopus wykazała szybki wzrost aktywności publikacyjnej na temat efektywności energetycznej w latach 2000–2020. Wciąż jednak brakuje badań na temat kształtowania zielonej marki danego kraju w zależności od tej polityki. W związku z tym dokonano selekcji odpowiednich publikacji, aby określić przyszłe kierunki działań w zakresie zwiększania efektywności energetycznej dla wzmocnienia zielonej marki Ukrainy. Aby osiągnąć cele niniejszego artykułu, dokonano opisu kolejnych zrealizowanych kroków, wykonanych w następującej logicznej kolejności: określenie słów kluczowych dla odnalezienia odpowiednich publikacji; wyszukanie publikacji; przeprowadzanie analizy ewaluacyjnej według określonych metryk; zastosowanie analizy bibliometrycznej do badania słów kluczowych i ich współwystępowania. Analizę współwystępowania przeprowadzono za pomocą narzędzi programu VOS Viewer. Próba badawcza składała się z 3090 publikacji zindeksowanych w bazie Scopus opublikowanych w latach 2000–2020. W badaniu zidentyfikowano najbardziej produktywnych autorów, prestiżowe czasopisma naukowe oraz kraje i instytucje, których publikacji jest najwięcej w Bazie Scopus. Publikacje zostały pogrupowane w pięć grup tematycznych, które wskazują główne kierunki badawcze. Autorzy określili najbardziej pożądane kierunki przyszłych badań.

The article aims to provide a theoretical basis for the assessment of the institutional impact on oil production. The availability of fuel is the key driver of the functioning national economy, which determines the strategic and tactical landmarks of socioeconomic development and vectors of the country’s foreign economic course. Such tendencies are represented in the results of the provided correlation analysis of the fluctuation between oil-production volumes and greenhouse gas emissions, the use of alternative energy sources, the number of patents for oil production, and unemployment. The provided bibliometric analysis, which was made using VOSviewer, has shown the content of interconnections between the categories of oil production and institutional determinants. The authors hypothesised that changes in the institutional environment and their interconnectedness formed a chain “oil production and oil rents → the level of corruption → the efficiency of public governance”. The hypothesis was confirmed by constructing a system of dynamic models and using the Generalised Method of Moments. The calculations confirmed that oil rents were associated with corruption and were a direct threat to the stability of public institutions. An increasing level of corruption was associated with an increase in the level of rent payments and occurred only when the quality of democratic institutions was below the threshold level. The current level of efficiency in public administration did not have a significant impact on national oil production. Of all indicators, only the level of political stability had a statistically significant impact on oil production. The identified interconnections provide the basis for creating an efficient state policy aimed at effectively functioning state institutions, which promote the development of the oil industry, and the reduction of the country’s energy dependence as well as strengthen the resilience of the national economy.

The aim of this research is to study theoretical and practical aspects of the ecological and economic losses from the use of solid domestic waste (SDW) as energy resources in the heat power industry of Ukraine. The methodical approaches to evaluating the ecological and economic losses caused by solid domestic waste (SDW) comprise: the developed algorithm, which evaluates the ecological and economic losses in the SDW use as fuel and energy resources in comparison with basic and project variant; the investigated morphological composition of SDW in the Ukrainian regions, on the basis of which there is proposed a matrix for further calculations of the ecological and economic loss from atmospheric pollution as a result of the energy-intensive SDW combustion at the power plants by the Ukrainian regions. The efficiency of using SDW as secondary energy resources, which essentially depends on the conventional energy resources combustion, is proved. According to the chemical and morphological composition of SDW, the average amount of harmful substances by their element constituents of SDW is determined. The economic loss from the combusting 1 ton of SDW as energy resources is estimated. Reasonability of using SDW as energy resources, based on the optimal ratio between conventional resources and energy-intensive SDW through minimizing total production costs and possible ecological and economic loss, is grounded. It is proved that while estimating the ecological and economic losses, it is necessary to consider the SDW morphological composition and regional specific features regarding the location of heat and power enterprises and organized storage landfills. It is grounded that the obtained estimates of the ecological and economic losses may be used for identifying the ecological and economic evaluation of the SDW efficiency use in the heat power industry at the regional level.
