The aim of this article is to propose a measurable definition of green jobs based on balanced, durable and sustainable development, which is an example of both the Green Economy and New Public Management (NPM) concepts. This approach is justified due to the nature of NPM, which uses the goals of management and measures of effectiveness. In this paper, the definition of green jobs is formulated as tool for measuring, based on the Polish Classification of Activities (PKD), which has roots in the classifications proposed by UN the ISIC and Eurostat NACE. Then the ease with which this tool can be used is tested by determining the efficiency of labour market institutions. Therefore, the green jobs concept can be much wider than just a qualitative description of an organisation’s strategy. In this paper it is proposed that green job characteristics based on section E of PKD is more specific and because of its quantitative approach it is a suitable measurement not only in Polish conditions, but generally.

Electricity Price Forecasting (EPF) influences the sale conditions in the energy sector. Proper models of electricity price prognosis can be decisive for choice between energy sources as a start point of transformation toward renewable energy sources. This article aims to present and compare various EPF models scientific publications. Adopted in this study procedure, the EPF publications models are compared into two main categories: the most popular and the most accurate. The adopted method is a bibliometric study as a variation of Systematic Literature Review (SLR) with specified automated queries supported by the VOSviewer bibliometric maps exploration. The subject of this research is the exploration of EPF models in two databases, Web of Science and Scopus, and their content comparison. As a result, the SLR research queries were classified into two groups, the most cited and most accurate models. Queries characteristics were explained, along with the graphical presentation of the results. Future promising research avenues can be dedicated to the most accurate EPF model formulation proved by statistical testing of its significance and accuracy.

The Industry 4.0 idea influences the development of both charging stations and electromobility development, due to its emphasis on device communication, cooperation, and proximity. Therefore, in electromobility development, growing attention is paid to chargers’ infrastructure density and automotive electric vehicles’ accessibility. The main goal of this scientific paper was to present the electromobility development represented in the number of charging stations and its infrastructure development calculations. In this study, the sequence of methods was used to indicate and explore the research gap. The first was the Structured Literature Review (SLR) variation method. The second method was the classical tabular comparison of gathered results. The third research method was a cluster analysis based on secondary data with cross-country comparisons of the number of charging stations and electric cars. Therefore, this paper presents a theoretical discussion and practical business implications based on the achieved results of clusters and rankings. The main finding of this paper is that charging stations play a pivotal role in electromobility development in countries with already developed road infrastructure and maritime transportation. The charging stations can support energetic infrastructure, especially in countries with vast geographical distances. The charging stations and electric vehicles statistics presented in ratios and ranks proved similarities in the electromobility development patterns in the analyzed countries. This paper also presents the limitations of the performed study and identifies possible future research avenues.

The article presents the current situation with the implementation of electric cars in Poland against the background of pan-European trends and the current energy sector condition in Poland. The aim of the study was to show the ecological, economic, social, and technical difficulties and controversies related to the use of electric cars in Poland. The authors used statistical analysis and identified the main factors of electromobility development in Poland. Despite the declared electromobility in the Strategy of Responsible Development program, the degree of its implementation is far from the previously established goals. The article analyzes the feasibility of the above plan and indicates the factors inhibiting the development of electromobility in Poland. The strategy and decisions to further implement electric cars cannot be purely political. In justifying the need to promote the use of electric cars in Poland, one should take into account the specificity of the Polish economy, its energy system, the condition of its infrastructure, and real social needs. The authors formulated a hypothesis that the aforementioned program is based on simplistic assumptions and marginalizes or ignores significant barriers to the development of electricity-based transport in Poland. The successful implementation of that program is conditioned by comprehensive and costly activities aimed to transform the whole energy system and introduce an effective system of incentives for the buyers of electric cars.

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.
