This paper aims to present different patterns of keyword evolution and their co-occurrences in publications dedicated to energy sales forecasting in a sustainable development context, and indexed in the Scopus and Web of Science Core Collection (WoS) databases. The adopted method is the Structured Literature Review (SLR) variation method with queries supported by the Bibliometrix software as the analytical and visualisation tool. The number of publications has evolved in the context of indexed keywords, which are related. Research on energy sales forecasting and sustainability has earned considerable attention in multiple academic fields. Proposed queries syntaxes and searching procedures in Scopus and Web of Science databases present limitations related to the subscription of these databases and the interchangeability of syntaxes. The novelty of this study is based on the results and their presentation with the usage of Bibliometrix as a tool for the exploration of two independent scientific areas, namely energy sales forecasting and sustainability, and the presentation of connections between them. This paper can inspire researchers to develop the subject of energy sales forecasting evolution in a sustainable development context, as well as business practitioners interested in energy sector adaptation visible in keyword changes in their decision-making processes.

This article presents the findings of a literature review and an empirical bibliometric analysis aimed at identifying green research perspectives within the energy sector of the Visegrád Group countries (Czech Republic, Hungary, Poland, and Slovakia). These perspectives reflect key scientific directions related to Sustainable Development (SD), environmental protection, and social responsibility. In this context, the theoretical principles of SD are translated into practical strategies, innovations, and solutions that support long-term economic growth while respecting ecological limits and social needs. Such themes frequently appear as dominant keywords in academic publications, underscoring their growing importance in energy research. The study pursued two main and complementary research objectives. The first was to identify green research perspectives prevalent within the energy sector of the Visegrád region. The second was to determine whether, and how, existing scientific publications address the topic of green jobs in this specific regional and sectoral context. The analysis led to the classification of five thematic categories: (1) green economy and finance, (2) green policies and strategies, (3) green energy and its sources, (4) green technology, and (5) green transport. These areas, when examined collectively, reveal important synergies that could support the creation of green jobs. Among the publications analyzed, green energy emerged as the most frequently addressed topic. However, the study found a lack of direct focus on green jobs, indicating that this subject—arising from the intersection of several research areas—represents a promising direction for future studies. In addition to these five categories, the study also identified several emerging green research directions within the Visegrád energy sector. These include: the development of green hydrogen technologies, the greening of the gas sector, the integration of prosumers into energy systems, the societal and political acceptance of nuclear energy, the role of green public transport in accelerating the energy transition, and the formulation of just transition policies. These themes highlight both technological opportunities and socio-political challenges that must be addressed to ensure a comprehensive and inclusive green transformation in the region.
