Abstract The paper analyzes the known risks of power supply failure in the case of further development of renewable energy sources. The use of FMEA analysis allowed to analyze the significance of various risks of alternative energy. It is shown that the use of the FMEA method is becoming one of the most important areas of technosphere safety for the further development of alternative energy. The introduction of the share of alternative energy into the total energy balance leads to a decrease in the share of traditional sources of energy generation. In turn, a decrease in the share of traditional sources of energy production in the case of a combination of unfavorable natural factors causes to the collapse of the energy supply system and causes a complete shutdown of alternative energy.

The paper analyzes the peculiarities of the development of the energy sector in Ukraine, as well as in European countries. Existing approaches to energy production are shown. The situation in Ukraine has changed in recent years. Energy production has shifted from centralized to distributed. The emergence of new types of power plants has made it possible to connect to the grid in places where it was previously impossible, a large number of consumers already have their own power units. Therefore, managing the energy network is becoming increasingly complex and therefore requires new approaches. The normative and legislative beginning of the active development of alternative energy in Ukraine already exists, and European and world experience should help Ukraine achieve energy independence and high environmental standards. Existing problems in the development of power grids arise due to the intensive growth of production and consumption of electricity, while the management of power systems is complicated by the growing share of distributed and renewable energy sources with changing production schedule. Improved controllability of electrical networks allows to prevent emergencies by load control programs, division of the network into autonomous zones, etc. Investment is a crucial factor in creating a flexible and efficient power grid based on innovative technical solutions. Implementation of energy efficiency projects is a guideline for improving the intelligent level of the energy system, which will allow energy companies to manage the energy network as a single system, increase profitability, reliability and uninterrupted, reduce technical and commercial losses, improve network management and efficiency. An important role is played by the interaction of all stakeholders in projects - the state, production, energy and energy sales companies, consumers and equipment manufacturers. Thus, the international experience in the transmission and distribution of electricity creates opportunities for successfully implementing projects for the introduction of energy-efficient technologies in our Ukraine.

Ukraine has untapped potential for the production of own energy from renewable sources - processing of livestock waste (animal manure and bird droppings) with the formation of biogas, which can then be used to produce electricity, heat or fuel - analogues of natural gas (methane) (in particular, for own needs of farms). Currently in Ukraine, the generation of large amounts of waste on industrial farms is an environmental problem that needs to be addressed. Recycling livestock waste to generate biogas will partially solve environmental problems, as well as benefit from decentralized renewable energy production or fuel production. The role of renewable energy sources in energy production is constantly growing and now the issue of increasing the share of renewable sources in the energy balance of each country is relevant. In the supply of primary energy, the share of renewable energy accounts for 13% worldwide. Of these, biomass accounts for 10%, or 258 million tons per year, ie in the world biomass provides the largest share of energy supply from renewable sources. Domestic agricultural enterprises are significant consumers of fuel and energy resources, so they face the objective need to use alternative energy sources, including biofuels and the introduction of innovative energy-saving technologies. Biogas production is an efficient and attractive investment technology, due to the presence of significant raw material potential, favorable climatic and other. However, the level of introduction of this type of energy in the agro-industrial complex is insufficient, which is due to a number of issues, including insufficient level of practical recommendations for choosing power generators, their number, modes of operation taking into account daily energy consumption schedule, load and optimal efficiency. installations while providing autonomous power supply of the enterprise. This paper determines the level of energy supply of livestock farms through the use of biogas plants as a source of energy used for livestock waste.

It has been substatiated in the article that renewable energy sources have recently become one of the important criteria for the sustainable development of rural areas. The emphasis is placed on the search for new and improved existing technologies for the production of alternative energy sources, expansion of their implementation areas. It is substantiated that the main reasons for such attention to the energy supply of rural territories are expected exhaustion of fossile fuels resourses, sharp increase in their prices, imperfections and low efficiency of their use technologies, harmful effects on the environment. It is shown that the situation of energy dependence can be changed by conducting the corresponding energy policy, improving the regulatory framework and attracting investment in the development of non-traditional and renewable energy sources. It is highlighted that Ukraine has sufficient opportunities to provide an adequate amount of biofuels, primarily through the use of biomass potential of agricultural crops and fast-growing energy crops. It is researched that in conditions of a complex socio-economic situation in Ukraine, a significant energy dependence on energy imports, the search for alternative energy sources is of particular relevance. It is estimated that Ukraine is among the dozens of countries - the largest consumers of energy resources, with a small share in the structure of the world's product. It is proved that energy saving today becomes one of the most important priorities of socio-economic development in the national and regional dimensions. The necessary condition for successful work in national and world agrarian markets is constant work on increasing the competitiveness of products, in particular, reducing its value by reducing the energy intensity of production. It is substantiated that agricultural producers are actively working on the issue of reducing energy consumption per unit of output. It is determined that the majority of these measures is aimed at increasing the productivity of agricultural crops, increasing productivity of the livestock sector, technical and technological re-equipment of the production process. It was emphasized that special attention should be paid to the branches of animal husbandry, because this industry is a serious source of alternative energy production. This applies not only the large live-stock producing agro-holdings but also the small households that operate in rural areas, for which live-stock production is subsidied by the state. Besides, it may become a source of energy supplies for their own needs as well. It was investigated that each year large livestock farms and poultry farms can receive environmentally friendly biofuels in an anaerobic way and significantly improve the quality of sewage. It is determined that thermal efficiency of cogeneration units of biogas production depends very much on equipment for electricity generation. For example, the use of gas-fired internal combustion engines has a thermal efficiency of 70% to 75%, while in the case of using gas turbines and boiler-wastes thermal efficiency can reach more than 90%. It is concluded that one of the ways to reduce the dependence on energy imports and to improve ecology in rural areas of Ukraine is to develop alternative energy generation in agro-industrial complex. Ukraine should create all opportunities for the development of innovative technologies for the implementation of renewable energy sources; to provide conditions for serial production and implementation of bioenergy facilities; to promote the formation of the equal competitive environment for different types of fuel. This will promote green energy production

Abstract Nearing its 60th anniversary of foundation, the once unchallenged Organisation of Petroleum Exporting Countries (OPEC) faces a modern diminution of influence. This slipping grip of near-hegemonic control exerted over the petroleum industry, is partly reflective of the rising influence of unconventional energy sources, the rising popularity for alternative and renewable energy sources and a downstream consequence of its own exertion of power. With rising international demand for renewables as a means to provide global energy security, the role of the state remains paramount in meeting energy demands. The international framework falls short of enabling a framework that brings renewable energy past its domestic dependency and into an internationally traded commodity. Following the 1973 embargo against the USA, OPEC inadvertently spurred on the need for a diversified market of energy production to ensure global energy security free from the whims of oligarchic groups. The subsequent investment into alternative energy, including the rising technological advancements made in areas such as horizontal and seismic imaging technology (or, ‘fracking’), has led to the diversification of energy production sources and lessened reliance on external importers by the American energy consumption powerhouse. The lessening reliance on OPEC has had a consequential impact on the unofficial head of the organization, Saudi Arabia. From the proposed initial public offering of Saudi Aramco to Vision 2030, all signs point to looming economic troubles for the petroleum dependant state without adequate, and effective, diversification.

The presented article aims to study the relationship between consumption and production of renewable energy and economic growth expressed in GDP per capita of the countries that invest the most in the development of renewable energy (USA, EU, China), and in the global dimension – for comparison with Ukraine and Russia. The World Bank’s secondary data for 1990-2015 and methodology of linear regression modeling were used for the research. An analytical review of the growing global investment potential of renewable energy in terms of general dynamics, sectors and leading countries in the context of investments in renewable energy sources was carried out. The results of correlation-regression analysis demonstrate a high correlation relationship between alternative energy consumption and economic growth of more developed countries with high GDP per capita than countries with lower GDP. The findings are consistent with other publications reviewed in the research. In addition, the increase in both China’s and the world’s GDP in the share of alternative energy production has a positive impact, and the increase in the share of consumption is negative. Whereas at the level of such countries as the USA, the European Union and Ukraine – on the contrary, consumption itself has a positive impact. The development of alternative energy has a negative impact on the economic growth of the Russian Federation in both indicators. According to the results of the carried out study, it can be summarized that countries with both high and low GDP should take all necessary measures to increase consumption and production of renewable energy sources, which provides for the formation of a favorable investment climate for large-scale investments in renewable energy, which, in turn, will lead to an increase in the pace of economic growth in the long term.

Amidst the changes and adjustments of the international energy situation, the leading trend is to shift from fossil fuels to low-carbon fuels, and ultimately, to enter the era of sustainable energy, based mainly on renewable energy. The ongoing changes in global security of energy supply and the high volatility of fossil energy prices also stimulate investment in alternative energy sources, making renewable energy sources (RES) one of the rapidly growing elements in the global energy system. This article fills the research gap by analyzing the potential of using renewable energy in the countries of the Commonwealth of Independent States (CIS) in the years 2015–2018. The authors address the energy potential in the years 2015–2019, and energy consumption in the years 2015–2018 as the potential of RES in the CIS countries was not researched after 2014. Please note that the study covers the CIS countries, along with Georgia and Ukraine, which are no longer formal members of the Community, but have been included for cognitive and comparative purposes. Upon comparing the increase in energy production in the CIS countries to the average increase for the European Union (EU) countries, the value of this increase is observably higher than the average for the EU countries only in Ukraine. However, the average for the entire CIS is much lower than the EU average, therefore in CIS countries, the changes in the volume of RES energy production are varied. In some countries, there is a significant increase in the production of this type of energy (e.g., Ukraine, Kyrgyzstan, Belarus, Kazakhstan, Georgia). However, there are also countries in which the changes are negligible, or which noted significant drops in RES energy production (Uzbekistan, Moldova, Russia, Armenia). The findings contribute to the RES market debate and the international relations theory by comparing political factors with territorial and economic factors.

Native American reservations are among the most economically disadvantaged regions in the United States; lacking access to economic and educational opportunities that are exacerbated by “energy insecurity” due to insufficient connectivity to the electric grid and power outages. Local renewable energy sources such as wind, solar, and biomass offer energy alternatives but their implementation encounters barriers such as lack of financing, infrastructure, and expertise, as well as divergent attitudes among tribal leaders. Biomass, in particular, could be a source of stable base-load power that is abundant and scalable in many rural communities. This case study examines the feasibility of a biomass energy plant on the Cocopah reservation in southwestern Arizona. It considers feedstock availability, cost and energy content, technology options, nameplate capacity, discount and interest rates, construction, operation and maintenance (O&M) costs, and alternative investment options. This study finds that at current electricity prices and based on typical costs for fuel, O&M over 30 years, none of the tested scenarios is presently cost-effective on a net present value (NPV) basis when compared with an alternative investment yielding annual returns of 3% or higher. The technology most likely to be economically viable and suitable for remote, rural contexts—a combustion stoker—resulted in a levelized costs of energy (LCOE) ranging from US$0.056 to 0.147/kWh. The most favorable scenario is a combustion stoker with an estimated NPV of US$4,791,243. The NPV of the corresponding alternative investment is US$7,123,380. However, if the tribes were able to secure a zero-interest loan to finance the plant’s installation cost, the project would be on par with the alternative investment. Even if this were the case, the scenario still relies on some of the most optimistic assumptions for the biomass-to-power plant and excludes abatement costs for air emissions. The study thus concludes that at present small-scale, biomass-to-energy projects require a mix of favorable market and local conditions as well as appropriate policy support to make biomass energy projects a cost-competitive source of stable, alternative energy for remote rural tribal communities that can provide greater tribal sovereignty and economic opportunities.
