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.

The article considers the legal basis for the formation and development of the country's energy sector, in particular, the issue of energy production from renewable sources, among which the leading place belongs to wind energy. The tendencies of the world energy market, which minimize the negative impact on the environment, as well as the tendencies of development of this branch in Ukraine are investigated. It was stated that for our country wind energy is one of the strategic directions of development of the sector of alternative energy sources, given the high dependence of the country on imported energy, primarily natural gas, and significant potential for wind power, taking into account the location, climate and terrain. However, unfortunately, the pace of development of wind energy in Ukraine still lags significantly behind European ones. It is noted that the legislative provision of the use of wind energy in Ukraine as a source of alternative energy is characterized primarily by the number of bylaws, general declarative legislation, as well as some inconsistencies in legal regulation. An analysis of current legislation and a number of regulations governing the development of the industry in general and wind energy in particular. A review of the norms that relate purely to the issues of the research area and their features and direction of legal regulation. In addition, it was stressed that Ukraine's accession to European initiatives, as well as borrowing international experience in this area should positively affect the energy balance and ensure the development of the sector, in particular, in the light of the need to create a full competitive environment in Ukraine's energy market; changes in heat generation by renewable energy sources and the full transformation of coal regions, which means the gradual closure of unprofitable enterprises with the parallel creation of alternative jobs in these regions.

The article aims to study current trends in the use of solar energy in Ukraine and the world as one of the main directions of decarbonization of the national economy. The authors systematize the prospects, advantages and disadvantages of the development of renewable energy sources. They conducted a comparative analysis of the "efficiency" of solar energy in some countries and Ukraine. The authors determined that the leading position in terms of the share of energy consumed from renewable sources is occupied by countries with developed economies due to the availability of effective motivational mechanisms. From the experience of EU countries, the authors concluded that renewable energy sources form a prerequisite for obtaining additional socio-economic and environmental effects. In the presence of favorable market conditions, renewable energy sources can increase the level of energy security in the country and its energy independence. The article analyzes the legislation of Ukraine on stimulating the development of alternative energy. The authors proposed two opposed ways of further developing solar energy in Ukraine. In particular, the country can implement methods of using alternative energy, which developed countries have successfully implemented. Another area involves increasing research and innovation in implementing, using, maintaining, and utilizing energy-generating devices from alternative energy sources. Despite the polarity of the proposed directions for further development of renewable energy, in both cases, the state policy on attracting investment and promoting the use of energy from alternative energy sources is crucial. In addition, the authors noted the benefits for society from the development and implementation of alternative energy sources. The scaling up and promotion of energy production technologies from alternative sources can reduce carbon emissions, which has been an urgent problem globally.

Actuality of the problem. The article discusses the current level of use of alternative sources of electrical power in the world. The main areas of the global power development were determined, the statistical data of leading energy companies, analytical international organizations and financial institutions were analysed. For today, all civilized countries successfully switch to alternative energy sources: wind, solar energy, biofuels, etc. In addition, the use of solar energy is one of the most promising inexhaustible, renewable energy sources. The use of renewable energy sources replaces the traditional one, based on extractive technologies polluting the atmosphere with harmful emissions, and enhances the greenhouse effect, reduces the burden on the resource base and energy systems of countries and improves the environment. Sustainable development of the agricultural sector of the economy of Ukraine and, in particular, irrigated agriculture requires a reduction in energy dependence. In the structure of the cost of irrigation water, a significant share accounts for electrical power. That is why to increase the efficiency of irrigated agriculture, to ensure high and sustainable yields in the context of climate change, it is extremely important to reduce the cost of power consumption. The need to use alternative energy sources in the drainage complex of Ukraine as part of the implementation of the energy strategy of Ukraine, aimed at the transition to fficient use and consumption of energy resources is highlighted. The Institute of Water Problems and Land Reclamation deals with the investigations of measures and technologies to improve power efficiency to reduce the specific energy consumption for pumping water by pumping stations and to reduce the rate of power losses for water intake and water transportation by water supply paths. One of the effective measures to reduce power cost is the use of alternative energy sources, in particular solar energy. The economic potential of the measures for improving energy efficiency in irrigation systems wass estimated. Conclusions. The estimation showed that the use of modules of solar power plants installed above the surface of open irrigation canals will lead to lower energy costs in the face of a constant increase in tariffs, that is, it will help to increase the economic efficiency of irrigation, reduce the share of water resources in national energy consumption and have a positive environmental effect. The sale of surplus power to the energy system at “green” tariffs can significantly reduce the payback period for the modernization of the engineering infrastructure of irrigation systems.
