Energy security and independence is one of the key points in sustainable development. In modern conditions of rapid growth and development of technologies, more and more attention is paid to finding practical solutions for environmentally friendly and inexpensive energy production. For a long time, scientists from various fields of scientific activity around the world have been engaged in the development and use of alternative energy sources. The share of renewable energy sources in the generation of electricity around the world is growing steadily, which indicates an increase in the use of energy obtained from alternative sources, such as, for example, wind and sun. These trends testify to the desire of consumers to abandon the use of fossil energy sources and nuclear power plants as much as possible in order to ensure further sister development. Under the current conditions of the COVID-19 pandemic, the demand for electricity worldwide has decreased, however, as the study shows, this pandemic has not affected the development of renewable energy. The article analyzes modern trends in the development of renewable energy, taking into account the experience of the EU countries and leading countries of the world in this area. As a result, it was concluded that in modern conditions, to achieve sustainable development, transformation processes are needed in such an important area as energy. Various processes in the global economy, which contributed to the intensive development of alternative energy sources, served as a powerful impetus for such changes. Many countries have made significant progress in the development of renewable energy.

Currently, a lot of focus is dedicated to metal hydride alloy and options of their utilization. Mankind must solve energy problems due to constant population growth and use of non-renewable energy sources. The World resources of oil are limited and therefore the mankind must start utilizing the alternative energy sources for example hydrogen. Its known that the hydrogen can be stored by metal hydride alloys what it represents the safety way of storage with absence high pressure and temperature. The process by produce of the alloy with good absorption properties the research does not end. Some alloy absorbs the hydrogen after they produce immediately, however a lot of them need the activation for improvement or starting absorption process. Process of activation is very important for achieving the maximum capacity at moderate temperature.

The energy sector holds a crucial strategic importance for development and its sustainability. However, the energy reserves in Turkey are insufficient for the increasing energy demand. For this reason, the need for alternative energy sources has emerged. The fact that fossil fuels used in energy production will be exhausted and their damaging effects on the environment has made it inevitable for the world to use renewable energy. In Turkey, the following are the main energy sources used in electricity production: hydraulic sources, brown coal, natural gas, coal and fuel oil. The use of renewable energy sources in electricity production has shown a considerable development in the world over the past few decades. However, these energy resources have yet to be exploited to any large extent in Turkey. In this chapter, the range of potential renewable energy resources available for electricity production in Turkey will be analyzed in order to determine the necessary technical substructure to make these renewable energy resources more attractive.

The article presents some features of new technologies in the field of improving transport and its inherent environmental aspects of the use of lubricating oils and alternative energy sources in modern conditions of development of the global economy. Transport enjoys a predominant share in the consumption of lubricants in the world market and in fact about 57 % of the world production volume is used in this sector of the economy. In accordance with global trends, the design development of traditional reciprocating internal combustion engines is carried out in conjunction with the development and implementation of environmental requirements for them in the largest economies in the world - European Union standards (Euro-7), India (Bharat Stage VI - the equivalent of Euro-6 standard) and China (China 6 is a more stringent version of the Euro-6 standard), aimed at reducing exhaust emissions. Actual additions to the SAE J300 classification include relatively low kinematic viscosity of oils, which allows engine manufacturers to meet the requirements of environmental standards that regulate emission of particles with exhaust gases and fuel economy - reducing fuel consumption. The advent of electric vehicles is having an increasing impact on transport and energy infrastructure. This long-term trend will also affect the manufacturing sector, where demand for traditional lubricants is expected to decline. The transport market today is making progress towards reducing carbon dioxide emissions and increasing fuel economy. Despite this, further investments by the automotive industry in improving the design of piston engines around the world are declining, and the supply of new engines for car manufacturers after 2021 is predictably reduced.

With the rise in the demand for electric vehicles, the need for a reliable charging infrastructure increases to accommodate the rapid public adoption of this type of transportation. Simultaneously, local electricity grids are being under pressure and require support from naturally abundant and inexpensive alternative energy sources such as wind and solar. This is why the world has recently witnessed the emergence of renewable energy-based charging stations that have received great acclaim. In this paper, we review studies related to this type of alternative energy charging infrastructure. We provide comprehensive research covering essential aspects in this field, including resources, potentiality, planning, control, and pricing. The study also includes studying and clarifying challenges facing this type of electric charging station and proposing suitable solutions for those challenges. The paper aims to provide the reader with an overview of charging electric vehicles through renewable energy and establishing the ground for further research in this vital field.

Introduction. The amount of energy resources generated from the introduction of alternative energy is increasing every year, nevertheless this problem is increasingly being researched by scientists, economists and ordinary people seeking to improve the environment around the world. This is a very pressing issue for European countries. As a potential member of the European Union, Ukraine also intends to significantly increase its energy resources from alternative energy. The Verkhovna Rada of Ukraine has been acting in the same direction since 2003 when the Law of Ukraine «On Alternative Energy» was adopted and has constantly been amending them, the last of which is dated July 11th, 2019 [1]. However, accounting for alternative energy is a new topic of research, therefore it requires a systematic approach to the formation of accounting policies; a number of interconnected accounts of the Charts of Accounts of assets, capital, liabilities and business operations of enterprises and organizations; and application of appropriate software. Analysis of recent research and publications. Problems of alternative energy development were considered in the works of Ishchuk L., Kinash I., Lishchuk V., Lishchuk M., Moskovchuk A., Nikolaeva A., Pyrih S. and accounting and analysis are investigated in the works of Derii V. A., Zadorozhnyi Z.-M. V., Krupka Ya. D. However, the accounting aspects weren’t considered in detail, thus, in this regard, the topic of our study is relevant. The purpose of the study is to formulate a systematic approach to accounting and its automation in alternative energy enterprises in order to develop proposals for improving the efficiency of their activities. Methods. The article uses general scientific and specific research methods to study the systematic approach to accounting and its computerization in alternative energy enterprises. A situational analysis of alternative energy development is carried out. The graphical method was used to reflect the ratio of energy from the sun, biomass, wind (in percentage terms) for ten years in Ukraine. Topical problems of energy in Ukraine and in the world through the use of induction and deduction methods are revealed. The modeling method for the formation of the accounting system in small enterprises of alternative energy production has been applied. Results. A systematic approach to accounting for alternative energy is very important as it’s a significant segment in the set of activities. The Law of Ukraine “On Alternative Energy” and International Standards or National Accounting Standards and Financial Reporting Standards do not refer the specificities of accounting and reporting on energy receipts from alternative energy sources. In this regard, we propose in the Law of Ukraine “On Alternative Sources” to separate the section for accounting and reporting, as it is done in Article 26 of the Law of Ukraine “On the Electricity Market” [2]. In our opinion, in the Chart of Accounting it is advisable to replace the name of the sub-account 203 «Fuel» with the name «Natural and energy resources» with the corresponding analytical accounts 2031 «Cold water», 2032 «Hot water», 2033 «Electricity of own production», 2034 «Electricity purchased» , 2035 “Natural gas purchased”, 2036 “Biofuels”, and 2037 “Other renewable natural and energy resources” [3]. In addition, we believe that the government should encourage the development of small businesses, consulting and design services that would provide individual homeowners with the opportunity to equip themselves with alternative energy facilities. In this regard, it is necessary to develop an optimal model of accounting system for small alternative energy enterprises. In the segment of accounting and reporting automation, we propose companies to search for new software that will replace the Russian software “1 C Accounting”, because this software requires additional modules. In addition, this software is very risky due to the political situation in Ukraine. Hence, we believe that it is necessary to give priority to the improvement of domestic software. Prospects. Further scientific research can be developed to detail the features of accounting, reporting and control in small alternative energy enterprises. The level of readiness for the use of Ukrainian accounting and reporting software products, in particular in the alternative energy segment, as well as the formation of a unified network with the bank and investors, should be discovered.

Wind energy, like solar energy, is one of the cleanest sources of energy available to humanity. It is considered a fully renewable resource due to the fact that wind will always exist on our planet. Unlike solar energy, wind energy is very compact and has great potential for agricultural economics. Despite the fact that alternative energy sources account for about two percent, they are developing and spreading all over the world.

The article is devoted to the current state and analysis of factors affecting the use of alternative energy sources on a global scale. There is a constant growth in volumes energy consumption, which is associated with the stability of the global economy, increasing costs for heating and cooling in various parts of the world. At the same time in the most densely populated areas (China, India), coal accounts for up to 80 % of the energy balance, which leads to an increase in CO2 emissions. In this regard, the article notes the need to switch to the use of alternative energy sources (wind, solar, hydro, geothermal and biomass, nuclear energy). The article analysis the current state of energy sources in developed countries according to statistics for 2018. The authors concludes that the growth rate of renewable energy resources is insufficient, despite their advantage over traditional sources. In this regard, the factors affecting the efficiency of renewable energy sources were summarized. In addition, the article identifies barriers that prevent the acceleration of the rate of replacing traditional energy sources with RES. At the same time, state support measures and relevant legislative acts play a special role in stimulating and attracting the necessary investments.
