The increased demand for energy determines the need to search for its next sources. One of them could be renewable energy sources, whose importance is increasing, among others, due to the limited resources of fossil fuels. In addition, renewable energy production has many benefits, mainly environmental and economic. Moreover, the social aspects associated with it cannot be ignored. The aim of this work was to discuss selected social benefits resulting from the production of renewable energy. Among the most important advantages of renewable energy sources is their local aspect, since energy production solves many regional problems, mainly related to its transport. The issue of energy security is also essential. In the case of biofuel production, the possibility of involving waste in energy production is extremely beneficial. The use of renewable energy itself directly affects the improvement of the environment, which in turn has a positive effect on people. Nowadays, sustainable development is one of the most critical challenges of humanity. These activities are closely related to the use of renewable energy sources. It is important to pay attention not only to subjects related to the environmental and economic aspects but also the impact of renewable energy sources on society.

The urban energy model is based on imports from external sources. The continuous increase in energy demand due to population growth and development implies increasing resource requirements. The alternative is to use renewable energies that take advantage of urban resources. The diversity of typologies of cities in terms of resources, demands, architectural conditions, infrastructure, or density, makes a specific analysis necessary. This work identifies fourteen factors concerning the planning process that would allow choosing the most appropriate technology for a given city. Through consultation of experts, the existence of the resource is defined as the most prevalent factor, followed by economic conditions; On the other hand, it is detected that environmental aspects such as global warming, eutrophication, or acidification, are the least incidents when selecting technologies.

One of the key tasks for the world community is the development of energy, which is one of the fundamental components of the economy. However, one cannot deny the fact that energy is the main factor in environmental pollution, which leads to the constant search for such types of energy sources that would have a positive impact on the economic development of territories and favourably affect the environment, alternative sources to traditional ones. Currently, there is an energy transformation, the main condition of which is the development of alternative energy technologies. One of the prospects for the economic and environmental development of the territories is the efficient use of renewable energy sources, which are becoming increasingly important in the world community and the global energy balance, and are becoming a substitute resource for traditional fossil energy resources. The article aims to analyse the economic and environmental aspects of the development of renewable energy in Kazakhstan and identify the main prospects. In the framework of the study, the concept of renewable energy sources, their main types are defined, the opinion of various authors regarding the development of renewable energy sources is described, the main directions aimed at stimulating the development of renewable energy are considered. The development of renewable energy in Kazakhstan in comparison with other countries (USA, China, Germany, Russia) is considered, the main problems are identified, the prospects for the development of renewable energy are also considered. The prospects for further research are determined by the subsequent study of the development of renewable energy sources, taking into account economic and environmental aspects. The article is of practical value in the framework of generalising data on the development of renewable energy in Kazakhstan and foreign countries.

Full textAbstract:
The article deals with a current trend of the global energy market, which is characterized by rising tension in relations between the performers of the energy market regulation mechanisms, and it leads to the emergence of alternative energy sources. The article is called to identify the causes of renewable energy markets nascence, to make comparative description of Ukrainian and European Renewable Energy Markets attractiveness, and to characterize the state policy change in a renewable energy market. Different interpretation of nature and classification of the field of renewable energy in foreign and Ukrainian approaches shows the problem of legal criteria of renewable energy markets regulation. It is proved the existence of double barrier penetration of the European market for renewable energy for Ukrainian companies, which includes compliance with the accepted EU Directives and compliance with the Rules of each member individually. The presence of clearly defined standards and certificates of quality for the European market allows producers to show the competitiveness of Ukrainian products in the international market and stimulate Ukrainian manufacturers. The presence of clearly formulated laws, stable and balanced political and legal environment of the EU allows Ukrainian producers of renewable energy to develop such a strategy that considers the time factor, as the primary parameter of competitiveness in international business. The market of solid biofuels in EU is under formation, its development timeframe and uncertainty of environmental risks becoming is especially important for Ukrainian producers.

The use of renewable energy sources offers opportunities for regional and local development. Thus, it can be appreciated that the use of renewable sources can stimulate the development of local communities. An advantage is also given by an increased security in terms of local energy supply, but also by a reduction in energy transport losses. Recently, there has been some interest in investing in the development of energy generation technologies and especially in renewable sources. For the period 1990-2020, a comparative situation of gross electricity production and electricity production capacities for renewables is presented. Pollution and climate change can affect both the production and consumption of electricity. There has been interest in using more and more diverse sources. Given the interest in reducing energy consumption in transport, important measures are needed to increase the energy efficiency of transport. In the article, an analysis is made of the share of renewable energy in the final gross energy consumption, for the period 2004-2020, with particularization for the transport sector.

Recently, legal literature has given attention to the problems of innovative energy. Despite the negative consequences of the current global economic crisis, the ways out of it are in the mainstream of the country’s transition from the export of raw materials to the resource-innovative development with a qualitative renewal of the energy sector. These tasks are set in the strategic planning documents that determine the vector and prospects of energy, scientific and technological and other areas of development. Achievement of goals and long-term quality guidelines for the development of the energy sector on an innovative development path is associated, among other things, with alternative energy, the expansion of the use of renewable energy sources. The paper shows the possibilities and prospects of their use for small energy facilities, energy-deficient areas, and regions with decentralized energy supply. The advantages of using green technologies, renewable types of energy are manifested in energy conservation, energy security, reducing the negative impact on the environment, and solving environmental problems. The absence of a regulatory legal framework for the development of alternative energy is revealed; gaps in energy legislation in terms of innovative energy, stimulation of the introduction of innovative technologies, and the use of renewable energy sources are highlighted. The necessity of highlighting this direction in the energy strategy, other strategic documents in the field of environmental, economic development, energy efficiency and safety has been substantiated. The result of the study is new approaches to the formation and implementation of state policy, as well as the improvement of legislation in the field of innovative energy development.

Full textAbstract:
Energy production from biomass is now a very popular trend in energy generation. These initiatives are supported by the European Union legislation and state governments. Undoubtedly, the idea of renewable energy production can be justified and promising. However, it should be considered from a wider perspective of supply chain than merely focusing on the share of renewable sources in total energy production. The economic and ecological importance of biomass use to energy generation largely depends on the logistics of biomass supply to power plants. The location of biomass sources and the organization of supply are very important stages that impact on final economic results of energy production. Furthermore, the improper choice of means of transport and process organization for managing renewable sources of energy might have a negative ecological effect. Therefore, the authors attempted to analyze the cost-related aspects of biomass supply (including the seasonal biomass price fluctuation) to the analyzed power plant and the effect of this factor on financial results of energy production.

Full textAbstract:
The United Kingdom is particularly well endowed with renewable energy sources relating to wind, waves and tide as well as the normal waste products arising from an industrialized society. These and other renewable energy sources have much technological scope for development but less scope for economic use. Government support for these industries has been significant in recent years in allowing a number of schemes to become commercially possible. The technologies are diverse, the design engineering is in its early stages in many cases and the extent of the eventual integration of such energy sources into existing energy supply systems is not easy to foresee. Aspects of the economic, institutional and environmental factors influencing the exploitation of renewable energy sources for electricity generation are reviewed along with an assessment of the present developments in the various technologies. The need for further support within a long-term view of the whole energy supply scene is stressed as necessary to balance shorter-term commercial considerations.

Full textAbstract:
Against the background of diminishing traditional energy sources, increasing negative impact on the environment, also due to some energy sectors, as well as the growing threat of extreme increase in the waste on a global scale, SRES have a serious potential to play the role of one of the key methods to achieve a sustainable balance, without any harm to the economic development. In practice, if assumed that the total population of the Earth is 7 billion people, at least 5 million tons of waste is generated on a daily basis (not counting the industrial ones). Of them, circa 2 million tons are non-recyclable, but these could be transformed into energy. Modern technologies offer up to 50% conversion of the source materials into usable free energy––i.e. there is a potential for the generation of approximately 1 million МW/h per day, or at least 300–350 TW/h per annum. This amounts to the whole electricity consumption of 5–10 small developed countries likeBulgaria,Slovenia, etc. The improvement and implementation of the SRES technologies will require significant expenses for scientific research and development. A part of these expenses can be covered by the general provision of incentives for alternative energy sources, another part should be provided by external sources, including funding from the central budgets, grants, as part of public-private partnerships, etc. The offered article examines the economics of the SRES, and all related factors, including their role and place in the energy sector, significance for the protection of the environment and for the achievement of the sustainable development goals (SDGs), adopted within the UN. An attempt is made to develop the existing and to offer new criteria for a more accurate and universal definition of the SRES. The objective of the article is not to claim to be an universal and exhaustive study of all aspects, related to the nature and use of the SRES, but it is rather an attempt to systematize and carry out a comparative analysis of the main problems, related to the SRES, as well as to draw the attention and stir a wider discussion on a topic, which––according to the authors––undeservedly fails to be sufficiently incorporated into the studies and research, related to the alternative energy development. Special attention is drawn to the opportunities provided by waste-to-hydrogen solutions alongside with other waste-to-energy approaches. Authors are also introducing for the first time the notion of “double-green-solution” as a specific feature of the waste-to-energy solutions. The article may be of interest to economists, investors and practitioners.

This paper tries to offer lessons about the very long run aspects of a future economy reliant predominantly on renewable energy sources. The evidence is based on past economies and civilizations and their experiences of economic expansion driven by renewable energy resources. The paper proposes that economies around the world, since antiquity, have managed to survive, and even develop and grow driven by renewable energy sources. Successful long run economic growth depended on sound management of demand, supply and trade of wood fuel. Where governments failed to develop appropriate policies, growth and development was severely constrained. Despite the uncertainty about the future, this paper proposes that researchers start to consider the nature of long run economic growth and appropriate policies within renewable energy systems.

Full textAbstract:
The gradual reduction of fuel resources, their depletion, as well as volatility of fuel prices led to a growing interest of countries in the use of renewable energy sources. Despite the fact that energy production in Azerbaijan currently largely depends on development of hydrocarbon reserves in the country, nevertheless, development of renewable energy sources is certainly one of the strategic priorities of the government. The main objective of the research is to study the economic problems and institutional aspects of introduction of alternative energy in Azerbaijan and develop recommendations to stimulate production of renewable energy. With the help of methods of comparative analysis and dynamic comparisons, the state of development of alternative and renewable sources in Azerbaijan was analyzed. The results of the study show that in order to increase the production of renewable energy it is necessary to take a number of measures in this area: improve legislation, introduce state incentives for consumers of alternative energy, apply a green tariff to attract investment, ensure transparency and consistency of energy policy.

The article is aimed at developing strategic directions and introducing regulatory measures for the formation of Ukraine’s energy policy on the principles of energy saving and the development of renewable energy industry. On the basis of scientific works, the main organizational-economic vectors of energy industry sector development are systematized, which are associated with the formation of a favorable socio-political climate regarding the priority of using renewable energy sources in the fuel and energy complex; development of effective methods of both the State-based and the market-based regulation by the world community; coordination of the strategy of sustainable development of the world economy. It is determined that the energy saving policy should be based on a flexible combination of the State-based regulation and the market environment for the formation of the most acceptable stimulation mechanisms in the specific economic and political situations, which allows for the greatest economic benefit. It has been found out that the implementation of energy saving processes is impossible without the mass use of renewable energy carriers, which are a universal resource for processing to the right types of energy, are marked by energy independence related to obtaining economic benefits and contribute to the creation of an ecological friendly environment. In the perspective, the energy saving processes, the transition of the national economy to wide implementation in the production of high-tech technologies and the use of renewable energy sources should become the determining factors of Ukraine’s energy strategy.

Aim. The presented study aims to assess the impact of the worldwide development of renewable energy on Russia’s geo-economic interests and to formulate proposals for reducing the negative aspects of such influence.Tasks. The authors examine materials related to the topic of the study; analyze trends in the development of renewable energy sources (RES) worldwide; identify threats to hydrocarbon exports from Russia associated with the development of RES; show Russia’s export potential in the hydrogen market; assess threats associated with plans for the production of hydrogen based on RES in the long term in countries that are major potential importers of hydrogen from Russia; formulate proposals for reducing the negative impact of possible threats.Methods. The research methodology includes the method of analyzing the primary data of the International Renewable Energy Agency (IRENA) on the level and pace of development of renewable energy in countries serving as major importers of energy commodities from Russia; data from the RENEWABLES 2021 (REN 21) report of the global renewable energy community, which unites the representatives of science, government, and industry; information posted on the official websites of the Ministry of Finance of the Russian Federation, the Ministry of Energy of the Russian Federation, the largest Russian mineral companies, and information contained in the works of Russian and foreign authors.Results. With existing technologies, renewable energy sources do not pose a significant threat to the exports of hydrocarbons from Russia for the next 5–10 years. This is due to the insignificant share of renewable energy in energy production and consumption, volatility of energy production depending on weather conditions, excess of investment in traditional energy compared to investment in renewable energy, and long-term contracts for the supply of fossil resources to China.Conclusion. During the active introduction of hydrogen energy (presumably until 2030), the demand for hydrocarbon fuel will persist if there is a tendency for its decrease In the long term, the development of renewable energy will inevitably lead to the replacement of Russian hydrogen imports with green hydrogen produced from renewable energy sources in importing countries. In this case, the global demand for hydrogen exports will inevitably fall, as will the demand for CO2 capture and storage services; the global price of hydrogen will decrease. During this period, it is advisable to specialize in the export of technologies, including in the field of hydrogen energy.

The relevance of the article is justified by the growing interest in alternative energy sources due to the limited reserves of fossil fuels and environmental pollution. The advantages of wind energy are presented: no need for any fuel, economic benefits, energy independence, and environmental safety. The process of obtaining electricity from the wind is considered. Comparison of wind turbines with battery and wind turbines without battery and comparison of wind turbines and power lines is conducted. Based on the analysis of the calculation results, it was concluded that a wind turbine without a battery is more economical than a wind turbine with a battery. In particular, the prospects for the use of wind power in the Arctic zone and in remote areas of the Russian Federation are considered. It is concluded that for residents of remote areas it is more economically feasible to use wind power plants as compared to traditional types of energy. The legislative and economic barriers to the development of wind energy as a type of non-traditional renewable energy sources are identified, and mechanisms for overcoming them are proposed. The article brings significant contribution in the field of political sociology both in its practical and theoretical aspects, being addressed to the politicians, scientists and management staff involved in this area of knowledge.

In the context of easing the dependence of most countries of the world on the import of fossil energy sources, a complex of systematic research on the search and effective use of renewable energy sources, in particular the development of the biofuels industry, is a necessary direction. An urgent problem need arises for the parallel implementation of the policy of diversification of supply and efficient use of fuel and energy resources with the active introduction of competition policy and infrastructure reforms in the economic and energy sector. Economically developed countries pay significant attention to energy supply on the basis of sustainable development, which determines the urgency of developing an integrated system of directions and priorities for the formation of Ukraine's energy security on the basis of its own biofuels production. The purpose of research is to provide scientific and practical substantiation and systematization of organization and innovative aspects of effective regulation of the development of competitive biofuels production in Ukraine at different levels of management. The methodical and practical experience of Ukrainian scientists concerning the division of Ukraine into natural-economic region was used. The methods of system analysis, monographic, graphical and abstract-logical are applied. The development of national biofuels production contributes to the efficient use of scientific, economic and labor potential and provides optimization of biofuel specialization areas. On the basis of the natural-economic region, it is necessary to form the main economic-energy proportions of macro-regional development and carry out balance calculations of production and consumption of biofuels. The formation of competitive biofuels production should be based on the principles of independence, self-sufficiency, accessibility and quality, based on clusterization processes. It is necessary to intensify the processes of increasing the volume and share of renewable energy consumption, giving priority to the development of the biofuels industry. Biofuels are a significant innovative contribution to the local energy supply of natural-economic regions, areas, administrative districts and individual agro-industrial enterprises to increase the competitiveness of manufactured products.

Full textAbstract:
Renewable energy resources (RESs) play an important role in the upgrading and transformation of the global energy structure. However, the question of how to improve the utilization efficiency of RESs and reduce greenhouse gas emissions is still a challenge. Combined heating and power (CHP) is one effective solution and has experienced rapid development. Nevertheless, with the large scale of RESs penetrating into the power system, CHP microgrid economic operation faces great challenges. This paper proposes a CHP microgrid system that contains renewable energy with considering economy, the environment, and system flexibility, and the ultimate goal is to minimize system operation cost and carbon dioxide emissions (CO2) cost. Due to the volatility of renewable energy output, the fuzzy C-means (FCM) and clustering comprehensive quality (CCQ) models were first introduced to generate clustering scenarios of the renewable energy output and evaluate the clustering results. In addition, for the sake of improving the flexibility and reliability of the CHP microgrid, this paper considers the battery and integrated energy demand response (IEDR). Moreover, the strategy choices of microgrid operators under the condition of grid-connected and islanded based on environment and interest aspects are also developed, which have rarely been involved in previous studies. Finally, this stochastic optimization problem is transformed into a mixed integer linear programming (MILP), which simplifies the calculation process, and the results show that the operation mode under different conditions will have a great impact on microgrid economic and environmental benefits.

A method is presented for justifying the construction of a mathematical model of the process of supplying consumers from local sources, taking into account deterministic input information. The target function of the mathematical model is to minimize financial investments in the construction and operation of the local energy supply system using renewable energy sources. Presented activities are aimed at assessing the efficiency of use of fuel and energy resources by local power supply systems, determining the conditions for a positive economic effect, substantiating the composition and main technical parameters of power plants and devices of the local power supply system. At the same time, the conditions of competitiveness of the local power supply system relative to the centralized one should be observed. Sources of local power supply systems should be built on the basis of biogas plants that are capable of producing biogas with long-term storage in gas storages and at the same time are energy storage batteries for other renewable sources. The presented analysis of the energy balance of a biogas plant, taking into account the synergistic effects of interaction between centralized and local energy systems, will make it possible to make optimal decisions for creating a bioenergy complex.

The increasing demand for energy threatens the earth with climate change due to emission of greenhouse gases from the burning of fossil fuels. This has been the major driver for green energy. Renewable energy has the potential to reduce the negative effects of energy production on the environment at a global scale. However, the technology to harness the energy from renewable sources have only been well developed for the electricity market. Expanding the scope to supply other markets and sectors would lead to increase in demand on rare earth minerals which will reciprocally create negative environmental and socio-economic impacts. In order to mitigate such impacts, strong regulatory policies will be required to control different aspects of renewable energy sources, the scale of production and footprint on the environment. Recycling renewable energy technology is a step in the right direction. However, the cost of recycling is found to be 5 times the cost of mining. This would affect the price of energy generated from renewable energy sources on a long run. A shift from fossil fuel would imply at least 20 trillion dollars in stranded assets which would trigger a financial collapse. This collapse would possibly lead to the complete loss of the oil, gas and coal industries, power producers, insurance companies and banks that hold loans for these industries.

Full textAbstract:
In the era of globalization and rapid economic growth, affecting most world economies, increased production and consumption are leading to higher levels of energy production and consumption. The growing demand for energy means that energy resources from conventional sources are not sufficient; moreover, its production generates high costs and contributes to the emission of greenhouse gases and waste. In view of the above, many countries have opted to implement an energy transformation. The energy transition allows the transition from an energy system based on conventional fuels to an energy system based mainly on renewable energy (RE) and low-emission sources. In the EU, the development of a “green economy” has become a strategic goal in the fight against climate change. The development of RE offers the possibility to improve the energy security of a given country and the entire EU. New, innovative technologies of RE also increase the attractiveness and competitiveness of the economies of the Member States. In line with the EU strategy, the activities carried out aim to achieve a situation in which, in 2050, the activities of economies will not endanger the environment. The main purpose of this article was the assessment of the RE sector in the Pomerania region in the context of energy transformation. To achieve this goal, PEST analysis regarding the functioning of the RE sector in the selected Polish region was used and the potential of the RE sector was determined using GIS tools on the basis of physical conditions. The article presents the research hypothesis that the RE sector within the Pomerania Voivodeship possesses appropriate energy potential, which will allow this Voivodeship to become an energy self-sufficient region based on the use of these energy sources (according to EU strategy). The implementation of the goal set in the article allowed for the verification of the research hypothesis, where the determined energy potential from the RE sector would cover the Voivodeship’s needs due to the use of electricity and heat. The conducted research shows that the RE sector in these regions has high energy potential to meet the criteria outlined in EU legal documents and to implement them successfully within the intended period.

This article presents a mathematical model to calculate the cost and production of electrical energy of a system that combines energy storage through renewable sources such as wind and solar energy, applying a theoretical framework of mathematical aspects to evaluate a pumped storage system with Pelton turbines, using a novel methodology, easy to replicate. The results show that a greater increase in the diameter in the pipe of the pumping equipment reduces the electrical power supplied to the pump. On the other hand, the hydraulic losses in the pipe leading to the Pelton turbine are negligible for long lengths, so setting the maximum length instead of a variable-length with the hydraulic height does not affect the result. Finally, the information and explanation of each of the graphs that correlate to the variables of interest are shown. This seeks to offer a contribution to support technological development in areas that do not have electricity, taking advantage of natural resources.

The article considers the state and prospects of bioenergetics development in the context of rationalization of the use of available natural resource potential of Ukraine. It is determined that one of the most perspective renewable energy sources is biomass, the main component of which is by-product of plant growing. It is noted that the use of by-products of crop production for receiving heat energy is a rational way to utilize their surpluses that are not used for other purposes of agriculture. The existing resource potential of this agricultural biomass and source of its obtainment were characterized. An estimation of the potential of this type of biomass up to 2025, which can be used for thermal power engineering was made. It was noted that the effective use of biomass potential of agricultural enterprises is possible in case of creation of the appropriate mechanism, a set of management decisions aimed at solving the energy issue. The structure of the formation of the economic model of the influence of factors on the state of the use of by-products of crop production in thermal power engineering was proposed.

The optimal utilization of renewable energies is a crucial factor toward the realization of sustainability and zero carbon in a future energy system. Tidal currents, waves, and thermal and salinity gradients in the ocean are excellent renewable energy sources. Ocean tidal, osmotic, wave, and thermal energy sources have yearly potentials that exceed the global power demand of 22,848 TWh/y. This paper extensively reviews the technologies related to energy harvesting from waves, tidal, ocean thermals, and the salinity gradient. Moreover, the socio-economic, social, and environmental aspects of the above technologies are also discussed. This paper provides a better picture of where to invest in the future energy market and highlights research gaps and recommendations for future research initiatives. It is expected that a better insight into ocean energy and a deep understanding of various potential devices can lead to a broader adoption of ocean energy. It is also clear that further research into control strategies is needed. Policy makers should provide financial support for technologies in the demonstration stage and employ road mapping to accelerate the cost and risk reductions to overcome economic hurdles. To identify traditional and online sources on the topic, the authors used electronic databases and keyword searching approaches. Among them, the International Renewable Energy Agency data were the primary database utilized to locate sources.

AbstractThe world energy consumption is going to rise by nearly 50% in 2050 when compared to 2010. With conventional and unconventional reserves depleting, demand for energy supply is rising. The feasibility and the current efficiency of renewable energy sources may not be capable of satisfying the world energy demand by themselves. Increase in production of non-renewable energy source, i.e., the fossil fuels may help to fulfill the energy requirement of future generations. Shale gas is one of the unconventional sources of energy. Shale gas deposits are scattered all over the planet in low-permeability and low porosity reservoirs. India has overall reserves of shale gas between 600 and 2000 TCF, of which 63 TCF is of recoverable shale gas (Pradhan and Prakash 2000). Shale production depends on many factors such as political matters, wars, social and economic aspects, and exploration techniques. Depending on the recoverable reserve (RR), production of shale gas entails different methods and with a different method, comes different problems described and discussed in this manuscript. Along with the problems, the technically recoverable reserves of different countries, different production mechanisms, and economic aspects of shale gas are also discussed.

Both the current state and prospects of secondary and renewable resources use within the closed complex of a mining enterprise have been considered. Relying upon philosophical approaches as for the formation of a viewpoint concerning responsibility of the modern society to future generations, tendencies to form energy production and energy consumption on the basis of alternative radical technologies have been proposed. The authors have put forward tendencies to change coal mining and coal use while generating the raw material from the abandoned and out-of-balance reserves. Chances to use cogeneration systems by various energy sources have been considered. Formation of the unified power and chemical system to improve economic and ecologic expediency of the proposed measures is the key tendency of energy perfection as well as minimization of impact on the underground mine environment and on the surface to prolong activities of dying mining territories and to reduce social tension.

Power generation through renewable sources is an effective alternative to mitigate climate change as its environmental impact is lower compared to fossil fuels. However, socio-economic problems are constant in sites where power plants are installed, especially in developing countries. In this paper, an innovative methodology was developed to assess the suitability of electricity generation through solar, wind, and biomass energy. Unlike most studies found in scientific literature, this work considers social, environmental, and economic aspects as key to determine the suitability of energy projects. First, we carried out a comprehensive analysis on social acceptance and resilience towards renewable energy and the conditions for communities to benefit from these projects; then, we analyzed the availability and capacity of renewable energy sources in Mexico, as a case study. Next, a set of indicators related to the three pillars of sustainability was developed to assess the conditions of each place with the best renewable resources in the country. The life cycle and capacity factor of each technology were also considered. Lastly, a mathematical model was developed to determine the most suitable locations and technologies for power generation. The results show a trend towards the states of northern Mexico, especially those bordering the United States, as the most viable for electricity generation. The most appropriate technology is wind energy. Finally, Oaxaca, the state with the best wind resources and current leader in wind power generation in Mexico is, by contrast, the least viable state for wind generation, as has been later confirmed by scientific evidence, as wind facilities are associated with severe socio-cultural and economic damage in host communities in this state.

More and more often, we talk about the use of renewable energy from the perspective of environmental protection. Competitive pressure in which reliability and efficiency are the key elements in capital development that shape the development plan of countries every year. However, we cannot look at this issue only from a climatic point of view. On a large scale, the production and the development of industries must thrive to the new standards, adapting also from the technological and financial point of view. The most visible effects are quantifiable in the form of employment, increase or decrease in GDP, dynamics of budget revenues and expenditures, applied taxonomy, and investment impact. In no country does the improvement of renewable energy take place without financial, social, and political support. EU countries have decided to allocate significant public funds under various support schemes for the progress of this sector. Accelerating the development of renewable energy sources (RES) also involves the introduction of mechanisms involving the use of private capital. In turn, this has effects on the level of local acceptance for development projects. In other words, this article presents first of all a synthesis of the key elements of the literature, dealing with the scientific, technical, economic, financial and environmental elements. The most important aspect is related to the contribution of the six renewable energy sources to the achievement of sustainable objectives. The purpose of this article is to provide information on how European Union countries have managed both fiscal and economic revenues from renewable energy sources. In order to establish the economic and financial efficiency of renewable energy sources, the mechanism and functionality of pricing systems were studied. The progress made by the countries studied is determined in particular by the degree of achievement of the objectives imposed by the European Union. Presenting the latest trends in RES, we pointed out the systems that support the development of renewable energy through solutions adopted as financial and environmental measures.

The article deals with financial and economic meaning of bioenergy as an important component of the country’s energy security. The problem of transition to renewable energy sources, in particular biofuels, was investigated. The relevance of research is that biofuels can fully replace traditional energy resources, increase the level of economic efficiency of production and competitiveness of national economy, as well as reduce amount of harmful emissions into the environment. The purpose of research is to study and develop theoretical and practical principles of financial and economic development of bioenergy and its role in ensuring energy independence of Ukraine. In the context of financial and economic crisis and political instability, the development of bioenergy industry is of priority in dealing with main social and economic problems. One of the main aspects of bioenergy development is states’ concern and use of targeted state funding. Moreover, other perspective ways to implement bioenergy technologies in Ukraine are public private partnership and attraction of foreign direct investments. Economic assessment of different ways of full or partial replacement of natural gas has shown that they can be supplied with biomass, while the total capacity of introduced objects according to the bioenergy development program can save natural energy resources. According to the formula of the method of average medium, the forecast of optimistic and pessimistic scenario of energy potential development is developed. Energy independence of Ukraine can be ensured through effective implementation of alternative energy with full state support, which will lead to acceleration of economic development of the territories, increasing level of life of people and environmental security of the country.

Hybrid microgrids are presented as a solution to many electrical energetic problems. These microgrids contain some renewable energy sources such as photovoltaic (PV), wind and biomass, or a hybrid of these sources, in addition to storage systems. Using these microgrids in electric power generation has many advantages such as clean energy, stability in supplying power, reduced grid congestion and a new investment field. Despite all these microgrids advantages, they are not widely used due to some economic aspects. These aspects are represented in the net present cost (NPC) and the levelized cost of energy (LCOE). To handle these economic aspects, the proper microgrids configuration according to the quantity, quality and availability of the sustainable source of energy in installing the microgrid as well as the optimal design of the microgrid components should be investigated. The objective of this paper is to design an economic microgrid system for the Yanbu region of Saudi Arabia. This design aims to select the best microgrid configuration while minimizing both NPC and LCOE considering some technical conditions, including loss of power supply probability and availability index. The optimization algorithm used is Giza Pyramids Construction (GPC). To prove the GPC algorithm’s effectiveness in solving the studied optimization problem, artificial electric field and grey wolf optimizer algorithms are used for comparison purposes. The obtained results demonstrate that the best configuration for the selected area is a PV/biomass hybrid microgrid with a minimum NPC and LCOE of $319,219 and $0.208/kWh, respectively.

The transformation of the energy sector towards an increased share of renewable energy sources in the energy mix requires attention in the area of electricity storage. Renewable energy sources (photovoltaics or wind energy) are marked by the intermittency of electricity production and require the construction of energy storage to adapt the energy supply to the demand, providing greater stability. The authors focused on verifying the solution of gravitational energy storage in existing shafts of hard coal mines in Poland. The issue is significant for Poland, as a country with an extensive mining infrastructure, which is searching for new scientific and practical solutions to utilize disused mining shafts for new purposes. In the analysis, the focus was on one shaft located within the Upper Silesian Coal Basin (Górnośląskie Zagłębie Węglowe), maintained for the drainage of the neighboring deposit. The article presents the calculation of energy that can be stored and an analysis of the effectiveness of energy storage in the shaft. The basic assumption of the analysis was 1 cycle of work per day (charging and discharging) in order to use the effect of low prices at night and high prices during peak hours (according to Towarowa Giełda Energii (TGE) quotations). Although energy storage already functions around the world, the studied case is new, because it refers to the usage of existing shafts which makes it a non-investment case. The results of the study showed that the obtained economic effects of the analyzed solution are low, therefore there is no economic justification of activities related to its implementation, taking into account the current price conditions.

Introduction. Today, the country is in energy import dependence, so there is a sharp problem of reorientation of needs and proposals related to the country's energy development. Despite the significant contribution of scientists to the development of theoretical and practical aspects of the introduction of renewable energy sources in Ukraine, a number of problems remain unresolved, in particular, in terms of benefits and prospects for the use of alternative energy sources in Ukraine. The purpose of this article is to determine the prospects and positive impact of the use of renewable energy sources in Ukraine. Results. The world is experiencing a rapid development of renewable energy, which is associated with the depletion of traditional energy resources, growing negative impact of energy on the environment, rising prices for traditional energy resources, as well as the desire of countries around the world for energy security and independence. Given Ukraine's growing energy dependence on Russian energy supplies and the constant rise in energy prices, the developing energy-intensive national economy suffers significant losses, leading to lower production and slowing down socio-economic development. Therefore, the issue of reducing energy dependence through the formation of an effective program of energy conservation and development of alternative energy in Ukraine should be considered as strategically important and in need of urgent solution. The main and most effective areas of renewable energy in Ukraine are wind energy, solar energy, bioenergy, hydropower, geothermal energy. Conclusions. The main modern views on the definition of “renewable energy sources” are studied. The energy strategy of Ukraine until 2035 is analyzed. The main advantages of renewable energy and its positive impact on the environment are identified. The most powerful solar power plants and wind power plants in Ukraine are listed. It is concluded that the use of renewable energy sources is environmentally friendly, modern, safe and resource efficient. Key words: renewable energy sources, solar energy, wind energy, biofuel, hydropower.

The article deals with the key aspects of the problem of determining the “carbon footprint” of industrial production. Rapidly increasing greenhouse gas emission within the past two centuries can cause irreversible changes in the Earth’s climate. Various manufacturing industries including “production and consumption of energy” create more than half of the “Earth’s carbon footprint”. The authors present a brief analytical overview of the “carbon footprint” problem in the context of solving a significant issue of global warming. They suggest references to current research and publications of Italian, Chinese and Spanish scientists. For example, Italian researchers proved that social innovations as well as transition to low-carbon technologies can be of good effect in reducing the “carbon footprint”. Chinese researchers (by analyzing 45-year-long data on the quantity of developed natural resources, energy consumption and population growth, “carbon footprint” and carbon dioxide emissions in the USA) proved that in the long-term perspective consumption of natural resources and renewable energy sources can improve the quality of the environment while population growth and consumption of non-renewable energy sources can contribute to its deterioration. Spanish researchers explored the connection between the “carbon footprint” and national peculiarities of people’s life. They listed the basic features of current energy transformation of the global economy (towards increasing the volume of renewable energy sources). The authors considered basic methods of regulating the “carbon footprint” of industrial production: by means of legal prohibition or improvement of pricing mechanism. They introduce the “Strategy of long-term development of Russia with low level of greenhouse gases till 2050”. The article contains information on reporting of greenhouse gas emissions in Russia.

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.

Recently, there has been an ongoing global debate on the issues of energy safety, energy autonomy, and energy alleviation policies in developed and developing countries. The energy communities can integrate distributed energy resources, especially among local energy systems, playing a decisive role to support people around the world in the transition process towards sustainable development and renewable energy sources (RES). The main research dimensions of such a manifold approach are environmental sustainability, the reduction of greenhouse gases (GHGs) emission, the ordinal exploitation of RES, the social awareness in actions towards global consumerism in an environmentally caring manner, the increase of energy efficiency, and the pollution relief caused by the expansion of urban/built environment worldwide. This review study focused on the roles and the ways of how “energy communities” (ECs) could support contemporary energy management and priorities to ensure energy safety, autonomy, and alleviation, regionally and globally. In this context, a systematic, last-decade publications of ECs was conducted and the retrieved documents were organized in alignment with the following four groups of literature overview. Group 1 covered the dimensions of technology and environment, being coupled with Group 2, covering the dimensions of socio-culture and anthropocentricity (mainly focusing on the built environment). A similar coupling of Group 3 and Group 4 was made, where Group 3 covered the legislative dimension of ECs and Group 4 covered the ECs devoted to Europe–European Union (EU), respectively. The emerging key literature aspects, the proposed measures, and the applied energy policies on ECs were also conveyed and discussed.

Energy politics of Slovakia is focused on sustainable economic growth and competitiveness by the means of sustainable Slovak energetics. The increase share of renewable energy carriers in the production of electricity and heat leads to a reduction in the consumption of fossil fuels and that consequently contributes to the reduction of pollutants and greenhouse gases. The existing regional potentials in the field of electricity and heat production are in the form of renewable energy carriers and the largest contributor is biomass. The development of the use of alternative energy sources aro uses a need for researchand development as well as new qualified professionals. The support from the European Union has enabled to build a work space that combines research and development activities with the processes of education and training and therefore is creating the conditions for the training of the professionals and the promotion of ideas in the field of renewable energy carriers.

Renewable energy is increasingly mobilizing more investment around the globe. However, there has been little attention to evaluating economic and regulatory (E&R) uncertainties, despite their enormous impact on the project cashflows. Consequently, this review analyzes, classifies, and discusses 130 articles dealing with the design of renewable energy projects under E&R uncertainties. After performing a survey and identifying the selected manuscripts, and the few previous reviews on the matter, the following innovative categorization is designed: sources of uncertainty, uncertainty characterization methods, problem formulations, solution methods, and regulatory frameworks. The classification reveals that electricity price is the most considered source of uncertainty, often alone, despite the existence of six other equally influential groups of E&R uncertainties. In addition, real options and optimization arise as the two main approaches researchers use to solve problems in energy system design. Subsequently, the following aspects of interest are discussed in depth: how modeling can be improved, which are the most influential variables, and potential lines of research. Conclusions show the necessity of modeling E&R uncertainties with currently underrepresented methods, suggest several policy recommendations, and encourage the integration of prevailing approaches.

The integration of renewable energy (RE) technologies into energy systems is essential to decarbonize the energy sector while meeting the growing demand for energy. The growing importance of RE in recent years has become one of the most important factors in the transformation of energy systems around the world. Many governments have strategic plans to reduce emissions in the energy sector. Some countries have even included a zero-point guideline in the law or proposed legislation, while others are discussing their own strategies. Many companies have also announced carbon-neutral targets. The success of renewable energy technologies gives governments and businesses some reason to be optimistic. At the same time, achieving these goals will require much more attention to sectors such as transport, industry and construction, which currently account for more than 55 % of CO2 emissions from the energy system. Achieving net zero will depend on how we deal with the emissions problem associated with the long-term assets of these sectors, many of which were recently built in Asian economies and can function for decades. Investments in new clean energy technologies will be crucial. Achieving net zero emissions in 2050 will require a much faster deployment of low-carbon energy. In the case of faster innovations, electricity production in 2050 will be about 2.5 times higher than today. A safe and sustainable energy system with zero emissions leads to the emergence of a new generation of basic fuels. The security of today's global energy system is largely ensured by the global markets of three key fuels – coal, oil and natural gas, which together account for about 70 % of the world's final energy demand. The paper considers the system integration of renewable energy sources in the world economy. An information dynamic model is presented as a research mechanism.

The study reviews the most relevant renewable energy sources, focusing on their possible application, economic aspects and potential for Hungary. Feasibility and economic analysis is made for plant-sized photovoltaic devices, wind turbines, geothermal power plants and biomass power plants. It was found that solar cell technology has the highest revenue. However, its further spread is limited by several factors, such as the reactive effect on the energy market, grid problems, and weather dependency. A possible solution for these problems is to use energy storage systems. For the sake of simplicity, only the economically mature technologies are investigated, including pumped hydroelectric storage, batteries, green hydrogen production, and thermal energy storage connected to a heat power plant. The payback calculations require a simple simulation algorithm to calculate the revenue using Hungarian data. With the simulation, the most important economic indicators are estimated. As a result of these calculations, we suggest a pumped hydroelectric storage to be built, or if it is impossible, the Paks 2 nuclear plant should be completed with a thermal energy storage facility.
