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.

In this study we aimed to determine the extent to which changes in the share of renewable energy sources, their structural complex, and the level of energy security in Eastern Europe, Caucasus and Central Asia (EECCA) countries in the medium- and long-term are interconnected. The study was performed through modeling and determination of the structural characteristics of energy security in the countries. The methodology of the approach to modeling was based on solving the problem of nonlinear optimization by selecting a certain scenario. For the study, the data of EECCA countries were used. The ability of EECCA countries to benefit from long-term indirect and induced advantages of the transformation period depends on the extent to which their domestic supply chains facilitate the deployment of energy transformation and induced economic activity. This study provides an opportunity to assess the degree of influence of renewable energy sources on the level of energy security of countries in the context of energy resource diversification. The high degree of influence of renewable energy sources on energy security in the EECCA countries has been proven in the implementation of the developed scenarios for its increase. Energy security is growing. At the same time, its level depends not only on an increase in the share of renewable sources but also on the structure of energy resources complex of countries, and the development of various renewable energy sources. Therefore, today the EECCA countries are forced not only to increase the share of renewable energy sources but also to attach strategic importance to the structural content of their energy complex.

The paper studies the role of alternative and renewable energy sources (ARES) in the maintenance of Azerbaijan’s energy security. In the view of annual depletion of reserves capacity of such traditional natural resources as the oil, gas, coal, shale and the environmental disorder in their usage, as well as considering the fact of their implementation as the major pressure means serving to the geopolitical interests of the countries, due to the instability and variability of the fuel types prices in the world market, the necessity of surveying new alternative and renewable energy sources in the region is marked. It is pointed out that wide-scale recovery of alternative and renewable energy sources in Azerbaijan will lead to the involving of oil-gas raw into the petrochemical industry, to the decrease of degree of the harmful man-made effect on the environment in the process of energy production, as well as to the significant reduction of economic dependence on the various fuel types. The methods of increasing the production capacity of alternative energies in the strengthening of country’s energetic safety by the acceleration of implementation process of alternative and renewable energy sources were studied and the significance of the development of oil concept considered the essential of long-term maintenance of national energy safety marked as well.

Goal of the work is to identify promising directions for sustainable development of the national electric power industry in order to ensure energy security of Ukraine, to conduct a comparative analysis of electricity sources, to confirm the need to improve the main sources – turbogenerators. Methodology. During the research, an analytical analysis of the electricity sources, which are installed at power plants in Ukraine and the world, was carried out, taking into account the growth of the planet's population and its energy activity. Cyclic theory was chosen as the theoretical basis for forecasting. On the basis of this theory, global development trends, advantages and disadvantages of currently used sources of electricity - thermal (including nuclear) power plants and stations that operate from renewable energy sources - have been established. A review of literary sources on the methods of the energy sector forecasting the development, including the development of the energy sector in Ukraine, has been carried out. Originality. It has been established that due to the active growth of the planet's population, with the increase in its energy activity, obtaining electricity from renewable energy sources is not enough, that for the next 20-30 years nuclear power plants will be the main sources of electricity. The internal and external threats to the energy security of Ukraine, directions of development of turbogenerator construction, ways to improve turbogenerators, to increase their energy efficiency, power per unit of performance, to increase the readiness and maneuverability factors, and overload capacity have been identified. Practical significance. The need to continue the modernization and improvement of the turbogenerators of nuclear power plant units, as the main sources of electricity, has been proved. The directions of their improvement are established: increasing the power in the established sizes, making changes to the design of the turbogenerators inactive elements, replacing the cooling agent to keep Ukrainian turbogenerators at the world level, improving auxiliary systems, improving and increasing the reliability of the excitation system, introduction of automatic systems for monitoring the state turbogenerators. Possible limits of use, advantages, disadvantages and problems of using renewable energy sources for Ukraine have been established.

The Impact

Introduction. The topic of renewable energy today is one of the most relevant and requires consideration from the point of view of all components of this process, namely economic, financial, environmental, technological, and others. The transition to renewable energy is already irreversible today since natural resources are depleted, fuel prices are the subject to significant fluctuations, and the stable growth of the national economy is ensured by energy security. The purpose. The purpose of the article is to analyze the volume of global energy consumption, to analyze the impact of the introduction of renewable energy sources on the development of the national economy, to ensure energy security with the depletion of hydrocarbon resources and a slight diversification of their suppliers. Results. Today the Ukrainian economy is the most energy-intensive. Unstable energy prices are a threat both to the global economy and to each country separately. Therefore, in the event of a decrease in the supply of traditional energy resources, the importing countries experience the greatest difficulties. The existing tendency in Ukraine to increase the consumption of traditional energy sources, combined with the absence of a targeted policy aimed at reducing the volume of environmental pollution, will lead to an increase in negative economic consequences. The advantage of renewable energy sources is their equal distribution throughout the country (with the exception of water resources). This feature leads to the formation of one of the main characteristics of power systems based on renewable energy sources, namely, their decentralization. It should be borne in mind that the world energy market is made up of state and non-state participants. Non-state participants are showing an upward trend. However, the state should have the greatest influence on the national energy sector. Renewable energy is an area that, in the Ukrainian context, depends on state support, namely economic and administrative incentives. The dynamics of the development of renewable energy should be combined with the balanced development of the fuel and energy sector in Ukraine. Conclusions. The process of development and transition to renewable energy needs a systematic approach. Both qualitative and quantitative approaches are needed to assess the transition to renewable energy. An effective strategy for the transition to the introduction of renewable energy technologies should be justified by economic feasibility. The transition from traditional energy to renewable sources should lead to energy security, which contributes to stable economic growth, political independence, and improving the quality of the environmental component.

For many years, the future of energy has been one of the most important problems and challenges for both national and global policy making. It is related to the high responsibility of the energy sector for climate change on Earth, but also for caring about ensuring sufficient energy for the future generations. Thus, energy policy is an important pillar of maintaining, broadly understood as internal security of the country. The biggest challenge related to ensuring energy security of the European Union is the diversification of energy sources. Member States are trying to tackle this challenge in two ways. Firstly, through the development of renewable energy, and secondly, looking for new channels for the supply of non-renewable energy. The restructuring of the energy sector, which has taken place in recent years, in accordance with the guidelines of the European Union, aims to intensify the use of environmentally friendly renewable energy sources. Equally important is the construction of the Nord Stream 2 and Turk Steam gas pipelines, which has been ongoing for several years, which raises much controversy in the Member States. The article is an analysis of the opportunities and challenges facing the European Union related to ensuring stable energy supplies to European citizens.

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.
