The Subject

The subject matter addressed in the paper concerns digital technology platforms in the context of renewable energy sources. The main goal is to check whether digital technology platforms can be effective factors in implementing innovative business models in the RES sector. The study was based on empirical research using Computer-Assisted Telephone Interview (CATI) and Computer-Assisted Web Interview (CAWI) methods, as well as on a model of attitudes towards digital technology platforms (DTPs) built using CATREG (categorical regression) analysis. As a result of the research, it was found that digital technology platforms contribute to building innovative business models. The decisive influence on this is a number of benefits for enterprises and consumers (and the related factor is the most important when it comes to attitudes towards DTP), as well as the high interest in digital RES platforms.

Implementation Of Innovations

This paper analyses innovative activities, including renewable energy sources (RES) in the housing market, the motivations for their introduction, effectiveness, benefits, limitations and management—which are open and current problems of Polish and international sustainable construction. This problem is part of a research gap concerning, among others, the role of developers and entities responsible for introducing energy innovations into housing construction. The aim of the paper is to analyse innovations, with particular emphasis on RES, introduced by residential developers in Poland in the context of global trends. The work is based on the results of surveys conducted among developers of the primary housing market. The research of 130 questionnaires received from entities such as multi-storey buildings and multi-family houses in Poland, was carried out on a nationwide sample using the CATI Computer Assisted Telephone Interview method. The results of the survey research were summarized by setting research hypotheses, which were verified using the significance test based on the Laplace normal distribution. The research conducted has shown that residential developers in Poland point at, among others, competitive pressures, concern about the quality of products and services offered, increasing market share or satisfaction and increasing customer requirements. This clearly shows that the implementation of innovation is perceived through the prism of increasing competitiveness. Furthermore, developers operating in the more competitive markets—nationwide and on the market of the five largest Polish cities, usually larger companies, showed a greater willingness and even the need to introduce innovation in their activities. In the study, developers as one of the barriers of introducing innovations, apart from the lack of adequate support, mainly from public entities in the field of, inter alia, appropriate law favouring the implementation of innovations and financial support, indicate difficulties of the client’s market manifested by the lack of knowledge and identification of needs in the field of innovation, and the lack of willingness to pay a higher price in regard to the product with higher innovation level. In the paper, the authors recommend developers, among others, to implement in the management process the identification of possible to implement innovations and the customers’ needs in innovations with education in the field of possible innovations and its benefits. The article indicates the need to intensify the implementation of innovations in housing projects in order to increase competitiveness and to meet the European Union’s requirement regarding the use of renewable energy sources.

Climate change is becoming a global problem. In many countries, actions are taken with the main aim of reducing CO2 emissions. The main action, especially in developed countries, is decarbonization. The European Union has become one of the organizations that plays a leading role in decarbonization of the economy. For this reason, renewable energy sources are being intensively developed in the EU countries. Solar energy with the use of PV installations is developing the fastest. Poland is one of the European leaders in photovoltaic development, and according to estimates for 2021–2025, it will continue to be. The aim of this study was to find out the opinions of people toward actions related to the decarbonization policy in Poland. These opinions were obtained through the prism of respondents’ attitudes toward energy produced by means of PV micro-installations. A questionnaire survey was used in this research. The survey was conducted using the CAWI (Computer-Assisted Web Interview) technique. To analyze the results of the study, a Kruskal–Wallis ANOVA test and U–Mann Whitney test were used. Responses were obtained from 633 people. The results obtained from the survey allowed us to draw conclusions, which include the following: (1) a lack of general conviction of respondents about the effectiveness of Poland’s decarbonization policy on reducing global CO2 emissions, especially among those who show a higher willingness to use PV installations, (2) the willingness to use PV installations is motivated by economic rather than environmental benefits, (3) the need for more widespread public campaigns aimed at promoting the benefits of decarbonization and renewable energy sources, and (4) the finding that the respondents’ region of residence (with a different degree of insolation) mattered for the willingness to use PV installations.

Support Functions

The gradual displacement of synchronous generators driven by conventional power plants, due to the increasing penetration of distributed renewable energy sources (DRES) in distribution grids, is creating a shortage of crucial ancillary services (AS) which are vital for the frequency and voltage stability of the grid. These AS, and some new ones, could now be offered by the DRES, particularly those that are converter interfaced, in a coordinated way in order to preserve the grid stability and resilience. Although recent standards and grid codes specify that the DRES exhibit some system support functions, there are no specifications on how to measure and quantify (M & Q) them both at DRES level and in aggregated form. The M & Q of AS is crucial, since it would allow the AS to be treated as tradable AS in the current and future AS markets. This paper attempts to define a number of AS that can be offered by converter-interfaced DRES and suggests methods for their M & Q. The new AS addressed are: (1) inertial response; (2) primary frequency response; (3) active power smoothing (ramp-rate limitation); (4) exchange of reactive power for voltage regulation; (5) fault-ride-through (FRT) and contribution to fault clearing; (6) voltage harmonic mitigation. Additionally, a rough estimation of the additional investment and operational cost, as well as the financial benefits associated with each AS is provided in order to form the basis for the development of business models around each AS in the near future.

Enel X is leading the transition toward a sustainable business model, with the circular economy as an important pillar. Using renewable energy sources and materials, extending product life cycles, creating sharing platforms, reuse and regeneration, rethinking products as services. The principles of the circular economy have become essential, considering the paradigm shift overturning the traditional linear economic model. Enel X was one of the first businesses to offer products on the market that concretely apply the five business models of the circular economy and reconsider the entire value chain from a sustainability perspective. This approach is characterized by two core principles: 1.  the first, addressed internally, focuses on the business’s product portfolio, which ranges from “measuring” circularity to identifying solutions for improvement; 2.  the second is directed toward the outside, and especially toward industrial customers and public administrations or end customers, with the goal of evaluating their level of “circularity” and helping them outline a roadmap to circularity.

SummarySubject and purpose of work: The subject of this analysis and evaluation is the use of renewable energy sources in Poland, particularly in the Lubelskie Voivodeship, as a peripheral region. The purpose of this paper is to identify the role and evaluate the scale and effects of using renewable energy sources (RES), as well as the availability and absorption of financial resources for RES promotion.Materials and methods: The data were obtained from the Office of the Ruda-Huta Commune, the Regional Operational Programme Department of the Marshal Office of the Lubelskie Voivodeship in Lublin and the Department of European Funds of the Ministry of Energy, as well as Statistics Poland (GUS) and the literature on the subject.Results: In Poland the proportion of energy from renewable sources to the total primary energy generated increased in 2012-2018 from 11.73% to 14.46%. A new phenomenon, which has been highly significant for the development of this sector, is the use of innovative, small-scale technologies of energy generation from renewable sources, which created the foundations for the growth of a citizens’ energy sector, based on the initiative of the citizens and their communities. The use of RES contributes to reduced expenditures on the purchase of energy carriers and constitutes an effective method of implementing plans for developing a low-carbon economy and reducing low-stack emissions.Conclusions: The continuing disparities between the regions point to the need for active structural intervention to maintain economic, social and territorial cohesion, particularly in areas which are considered peripheral and have a very low GDP per capita. One of the preferred directions should be to support the use of RES.

Energy Cluster

Clusters are an organisational and economic phenomenon. This paper attempts to answer what an energy cluster actually is and whether it meets the requirements of a cluster in the classical approach of economic sciences. The Act of 20 February 2015 on renewable energy sources (Ustawa OZE 2015) introduced the concept of an ‘energy cluster’. It was aimed at, among others, increasing energy security and environmental protection through an efficient use of renewable energy sources. In the literature on the subject, there is no single universally applicable definition of a cluster, it can only be considered in its various aspects. The concept of a cluster has so many applications, associations and meanings that in many respects it has become a ‘chaotic idea’ due to flattening and equalising different types, processes and spatial scales of economic location within one universal concept. However, the main doubt concerns the very definition of a cluster. The paper considers the organisational attributes of clusters, based on the analysis of the following aspects: a) Cluster in historical terms. Overview of cluster and network definitions: i. Overview of cluster definitions ii. Overview of network structure definitions b) Energy cluster. Forms of interorganisational relations and the typology of energy clusters i. Forms of interorganisational relations in an energy cluster ii. Energy cluster against in relation to organisational network typology iii. Energy cluster as a form of company network – common features and differences c) An attempt in characterisation and definition of an energy cluster.

This paper focuses on the analysis of trends in the development of nuclear energy in selected European and non-European countries in the context of the pace of renewable energy development in the world. The perception of Poles related to their openness to various energy sources against the background of European trends was also examined, as well as their ecological approach to the quality of the environment in this context. The survey was carried out using the Computer Assisted Web Interview (CAWI) technique. The total number of correctly completed forms was 923. To identify the ecological attitude, purchasing attitude, and the perception of nuclear energy, the research tool contained a number of statements on the issues studied, and the respondents assessed compliance with their opinion using a seven-point bipolar scale. The semantic differential was also used to gather opinions on the characteristics of nuclear energy. This paper shows that global trends are promoting the development of unstable renewable energy sources and the reduction of the share of nuclear power plants as an energy source. It has also been shown that the Organization for Economic Co-operation and Development (OECD) countries are more skeptical about nuclear power than countries that do not belong to the OECD (for example, China and Africa).
