Households are responsible for more than one-third of global energy consumption and exert a significant environmental impact. Therefore, energy efficiency and renewable energy issues have been a top theme in the literature, with numerous studies examining different facets of residential power consumption, green energy transition, decarbonization, and energy conservation. Despite extensive attention, these research trends and frontiers remain largely uncharacterized and poorly understood. This study aims to provide clear insights into the evolution and latest trends of household energy efficiency and renewable energy studies, reveal significant contributing countries, institutions, and authors of published papers, as well as directions of international collaboration. The method of bibliometric analysis with two supporting instruments (the SciVal platform and Scopus “Analyze search results” tool) was used to investigate an array of 3,761 research items on renewable energy and 4,474 items on energy efficiency in homes formed from the Scopus database. The studied period includes papers published during 1978–2023. The systematic review indicated that the United States, the United Kingdom, and China are primarily contributing countries with strong international collaboration in this field. The top journals include Energy Policy, Energy Efficiency, Energies, and Sustainability, while highly cited researchers investigate environmental, economic, and social effects and management mechanisms for introducing innovative energy-efficient and renewable energy technologies in households like smart meters and grids or the Internet of Things. The research frontier might encompass emerging and pioneering studies on home decarbonization strategies, behavioral interventions, energy saving, prosumerism, and optimization of energy consumption.

This study examined how multinational corporations adapted their corporate social responsibility strategies while operating in russia during the ongoing war against Ukraine. Specifically, the analysis investigated the impact of different corporate social responsibility approaches on financial performance, stakeholder trust, and corporate reputation for multinational corporations operating in russia during the war. A game-theoretic model evaluated three distinct strategies: minimal corporate social responsibility engagement (Strategy 1), increased corporate social responsibility involvement (Strategy 2), and a complete exit from the russian market (Strategy 3). The quantitative analysis showed that companies choosing the exit strategy (Strategy 3) gained the highest payoffs for financial performance, stakeholder trust, and reputation. In contrast, minimal corporate social responsibility engagement (Strategy 1) resulted in negative outcomes, including reputational damage and potential exposure to sanctions. On the other hand, increased corporate social responsibility involvement (Strategy 2) produced neutral outcomes, offering short-term benefits but still leaving companies vulnerable to ongoing risks. The sensitivity analysis confirmed the stability of these outcomes. The study concludes that exiting the russian market not only aligns with ethical standards but also ensures long-term sustainability, offering critical insights for corporations navigating corporate social responsibility challenges in war zones.

Abstract
The transition toward climate neutrality is reshaping economic systems and increasing the importance of human capital in green modernization. However, a significant gap persists between technological advances and the strategic management of the workforce. This study aims to systematize and conceptually map the contemporary scholarly landscape of human capital management research within the renewable energy transition. Using the PRISMA 2020 protocol, the study analyzed 2,258 Scopus-indexed documents published between 1994 and 2026 through bibliometric and science mapping methods. The methodology combined descriptive statistics, keyword frequency analysis, multiple correspondence analysis (MCA), and network co-occurrence cluster analysis using the Bibliometrix R-package and VOSviewer. The results show a rapid increase in publication activity, with an annual growth rate of 18.01%, with China, the United States, and India leading global output and the international collaboration rate reaches 28.6%. Science mapping showed that the term “human capital” entered this field more actively only after 2020 (297 occurrences), still lagging behind technological topics. MCA indicated a clear conceptual separation between knowledge domains: the relative distance between the educational and workforce clusters suggests that these themes are still weakly integrated in the literature. Network analysis identified five thematic clusters: the technological and educational foundation, macroeconomic environment and resources, strategic management and innovative transformation, the socio-labor dimension and labor market, and eco-technological regulation. These results point to the need for a more integrated approach to adaptive human capital development that connects technological change, professional mobility, and institutional learning and strengthens the role of human capital in supporting green transformation.
