With each passing year, the problem of using alternative energy sources is gaining increasing attention, since the energy of the sun, water and wind, unlike hydrocarbons, belongs to practically inexhaustible resources. Besides this, alternative energy sources are relatively environmentally friendly, so any country is interested in using them. One of the factors affecting the increase of energy generation from alternative sources is the legal regulation of this area by the government. In many foreign countries a number of conceptual, doctrinal and program documents are adopted and implemented, which are dealing with the use of renewable energy sources. In order to stimulate the use of alternative energy sources, the governments of some countries create favorable conditions for attracting investment in the development of this sector, which, further, not only creates new jobs, but also has a generally positive effect on the economy.

The growing human population and the increasing energy needs have produced a serious energy crisis, which has stimulated researchers to look for alternative energy sources. The diffusion of small-scale renewable distributed generations (DG) with micro-grids can be a promising solution to meet the environmental obligations. The uncertainty and sporadic nature of renewable energy sources (RES) is the main obstacle to their use as autonomous energy sources. In order to overcome this, a storage system is required. This paper proposes an optimized strategy for a hybrid photovoltaic (PV) and battery storage system (BSS) connected to a low-voltage grid. In this study, a cost function is formulated to minimize the net cost of electricity purchased from the grid. The charging and discharging of the battery are operated optimally to minimize the defined cost function. Half-hourly electricity consumer load data and solar irradiance data collected from the United Kingdom (UK) for a whole year are utilized in the proposed methodology. Five cases are discussed for a comparative cost analysis of the electricity imported and exported. The proposed scheme provides a techno-economic analysis of the combination of a BSS with a low-voltage grid, benefitting from the feed-in tariff (FIT) scheme.

The study in this chapter examined policy options for promoting solar PV diffusion into the energy mix of six selected remote villages that were pilot sites for national and foreign assisted solar electrification programs in three ecological regions of Nigeria. A total of 910 questionnaires were administered on the solar PV users, suppliers, and government agencies to elicit information on alternative energy sources for provision of energy services. The results showed that solar PV usage was 49.9 kWh per/day, which constituted an insignificant share of about 14% in the total lighting requirement and less than 2% of the total requirement for energy services. The demand would rise to 73.3 kWh per/day by 2019 at the same 14% share of the total lighting requirement. Firewood demand maintained over 80 percent share (2383.5 kWh per/day) in the total energy mix in 2009. It also revealed that the best policy option of 200 percent increase in solar bulbs’ share for lighting by 2014 would require 50% reduction in kerosene share. The study concluded that increasing utilization of solar PV for lighting, entertainment, refrigeration, and ventilation in the study areas could lead to decrease in the use of energy from alternative sources.

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 conventional fuels are necessity for all the automobile machineries, due to deficiency of conventional energy sources need to search for alternative sources like biodiesels should give more impact to the automobile sectors. Biodiesel are clean energy, eco friendly, easily possible to produce from biomass. Alternative energy sources having more capable for solving environment aspects like reduce the pollution to the environment. This paper deals papaya seed oil used as feedstock, in this biodiesel produced by transesterification method using potassium hydroxide (KOH) as catalyst. This biofuel is used in four stoke, single cylinder, variable compression engine (VCR). The rated speed of the engine is 1500 rpm. This emission performance is analyzing for different nozzles with blends. Carbon mono oxide (CO) slightly increasing with load, Hydro carbon (HC) slightly decreasing with load, Carbon di-oxide(CO2) increasing with load. Oxygen (O2) is decreasing with load. Nitrogen oxide (NOX) and particulate matter is also increasing slightly with load.

Many areas of the world today have access to alternative energy sources to meet their energy needs. A fundamental problem facing societies today is to determine the optimum utilization of energy sources. This paper analyzes the issues involving co-utilization of different types of energy production in Iceland. Formulating a dynamic social optimization problem, expressions are derived for optimal energy supply prices from each energy source. Based on the economic characteristics of the energy sources, an optimal solution is derived that involves both periods of specialization in a single energy source as well as periods of simultaneous co-utilization of available sources.
