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.

The energy sector is constantly changing. Electromobility, improvement of energy efficiency, smart cities these are just some of the challenges that the present power industry is facing. The main goal for the power industry is to ensure the energy security of its customers, to develop low-community technologies which are mainly based on renewable energy sources and local raw materials. The transition from a centralized energy sector based mainly on conventional power plants to a distributed energy sector requires constant control and management of the generation and demand for energy. One of the solution existing since 2016 are energy clusters. The concept of their functioning is based on the civil-law agreement of locally operating entities that produce, sell, store and consume electricity, heat and cold. The main purpose of introducing energy clusters is the development of distributed energy. Energy clusters ensure the improvement of local energy security with relatively low outlays and low environmental impact. Technological development and installations based on renewable energy sources make energy clusters a beneficial and cost-effective solution for local energy sector. The article presents the idea of energy clusters functioning, and describes the current status of development. It also includes the hybrid systems characteristics of RES systems as an effective source of energy. The conclusion includes the legitimacy of the energy cluster development based on RES installations.

Abstract BackgroundThe characteristic feature of modern energy sector in the EU is the development of environmentally friendly technologies based on renewable energy sources (RES). The use of alternative and RES contributes to resolving not only energy efficiency issues, but many of the environmental, economic and social problems. RES are also one of the priorities of the world's low carbon policy and reducing CO2 emissions into the atmosphere. Growing electrical energy consumption and increasing integration of RES in power systems have led to new challenges, thus it is required to investigate and properly analyze the impact of integrated RES on the power system as a substitute for fossil fuel resources.ResultsThe aim of the article is to show the possibilities of developing RES in Poland in the context of environmental protection, energy self-sufficiency and international obligations. The depletion of primary energy sources and the increase in emissions of greenhouse gases to the atmosphere forces undertaking certain activities, aimed at seeking substitutes for fossil fuels. According to the author’s analysis, RES are the best and safest substitutes for traditional energy resources such as fossil fuel.ConclusionsThe author examines electricity production mix in EU counties and compares it to Polish energy sector. Taking into consideration the transmission network density in Poland, while energy sector changes its structure and expands, the mix of technologies deployed to produce electricity determines the associated burden on transmission networks. Polish energy sector development in the context of modernization of transmission grid provides an opportunity for investors to prepare the energy system for increasing the share of renewable energy sources. In the process of implementing the appropriate solution, the experiences of other countries that have significantly increased the share of renewable energy in the past could be used. This article presents the main areas of action that may facilitate the further integration of different energy sources in the specific context of Poland's changing energy system. Not all integration options will be important for Poland at the same time.

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.

Abstract Increasing the share of renewable energy sources is one of the core policies of the European Union. This is because of the fact that this energy is essential in reducing the greenhouse gas emissions and securing energy supplies. Currently, the share of wind energy from all renewable energy sources is relatively low. The choice of location for a certain wind farm installation strongly depends on the wind potential. Therefore the accurate assessment of wind potential is extremely important. In the present paper an analysis is made on the impact of significant possible parameters on the determination of wind energy potential for relatively large areas. In the analysis the type of measurements (short- and long-term on-site measurements), the type of instrumentation and the terrain roughness factor are considered. The study on the impact of turbulence on the wind flow distribution over complex terrain is presented, and it is based on the real on-site data collected by the meteorological tall towers installed in the northern part of Bulgaria. By means of CFD based software a wind map is developed for relatively large areas. Different turbulent models in numerical calculations were tested and recommendations for the usage of the specific models in flows modeling over complex terrains are presented. The role of each parameter in wind map development is made. Different approaches for determination of wind energy potential based on the preliminary developed wind map are presented.
