New Renewable Energy (EBT) is an efficient solution to overcome the deficit of fosil energy resource such as crude oil and coal. In addition to this pandemic of Covid-19 in Indonesia made the price of crude oil in the world dropped dramatically to reach around $25/barrel crude oil of WTI as of May 8, 2020. Every resources in this world stores electricity. Nonetheless this resources need special processing so that they can be converted into electrical energy. This Research is focused in Banana Peel. Currently we know that the consuming of Banana fruit still increased especialy in the pandemic of Covid-19. Hence the more Banana fruits are consumed, the more Banana Peels are remained. This research aims to find the solution from the Banana Peel wastes in this pandemic – processing them and converting them into eco-alternative energy – by keeping the energy into the battery. The methods used in this research used an exxperimental method using the application of the Ohm’s law which aims to test the hypothesis by testing four banana peel samples (Ambon, Muli, Raja Hijau, and Raja Palembang). The results of this research showed that harvest the electricity from banana peels (BPEEH) can help the efficiency of deficit fosil energy resources due to this pandemi of Covid-19. It was showed that one battery of the banana peels pasta or BPEEH can give voltage 1.28 Volt and electricity current is 2.13 Ampere. In addition to for 12 batteries of BPEEH assembled series can turn on the 6 Volt LED lights for 4 to 5 days.

Abstract One of the trees that has fruit with high acid content that has the potential to be used as an alternative energy source is the acid contained in Singi (Dillenia serrata Thunb.) fruit. Therefore, this study aims to test the ability of the singi fruit to turn on the LED lights and determine the value of voltage, current and electrical power in the fruit. This research was conducted at the Laboratory Ministry of Forestry, Faculty of Forestry and Environmental Sciences, Halu Oleo University. In June-July 2019 using an experimental method for 5 days by measuring the acidity (pH) value of voltage, current and electric power. The results showed that the LED was on until the 5th day but the value of the electricity content tended to decrease, namely the first day with a power value of 7.533 watts and the fifth day 1.722 watts. While the acidity (pH) of the singi fruit which is decreasing over time affects the value of the electrical content contained in the solution of the singi fruit.

After the first oil-price shock of 1973, a search for new energy policies was started all over the world. Changing one fundamental concept - that relating to the general development of energy supply and consumption - was, however, out of the question. The pre-1973 trend of development was maintained. The energy elasticities did not change. The old forecasts were still held to be valid and were considered now, as earlier, to be the objectives which a successful energy policy had to achieve. This was considered a prerequisite for high growth rates of GNP and improvements in living conditions, and energy consumption was regarded as an indicator of the level of economic development. Therefore, the focus was shifted to an enlargement of the supply of indigenous energy resources as a substitute for imported energy, so that dependence on foreign countries could be minimized.

Purpose Ethiopia’s energy sector faces critical challenges to meeting steadily increasing energy demand given limited infrastructure, heavy reliance on hydroelectric power and underdevelopment of alternative energy resources. The purpose of this paper was to identify optimal least cost investment decisions for integrated energy source diversification. The authors seek to contribute to the relevant literature by paying particular attention to the role of public policy for promoting renewable energy investment and to better understand future energy security implications of various sources of uncertainty. Design/methodology/approach The authors created a dynamic linear programming model using General Algebraic Modelling System software to explore the national energy security implications of uncertainties associated with increasing technological advances and efficiency, and climate change scenarios. Findings To cope with the impacts of drought expected from future climate change on hydroelectric power production, Ethiopia would need to invest in the development of alternative energy resources. Such investment would not only enhance the sustainability and reliability of energy production but also increase costs. Greater rates of technological and efficiency innovations, however, were found to improve electricity diversification and reduce production costs and shadow prices or resource scarcity, and are thus key for enhancing energy security and reducing the risks posed by drought. Originality/value The dynamic linear programming model by the authors represents a flexible sector modelling tool for exploring the sustainability and efficiency of energy resource development pathways and evaluating the effects of different sources of uncertainty on the energy sector.

Human resource conservation is capable of being achieved along with energy resource conservation. The Crude-Oil Recovery Process (CORP) uses a single inerting/cleaning agent in a waterless, self-contained, closed-loop, remote-controlled and superport compatible system that eliminates human in-tank “mucking”. By using vaporous agent for inerting during discharge/refill operations, system safety is significantly increased. The same agent, in its liquid state, is used as an effective cleaning agent. CORP eliminates expensive and hazardous gas-freeing procedures and facilitates recovery of otherwise-lost agent and energy resources, while reducing air and water pollution, and improving human safety, morale, and growth potential.

Renewable energy has received noteworthy attention during the last few decades. This is partly due to the fact that fossil fuels are depleting and the need for energy is soaring because of the growing population of the world. This paper attempts to provide an idea of what is being done by researchers in remote sensing and geographical information system (GIS) field for exploring the renewable energy resources in order to get to a more sustainable future. Several studies related to renewable energy resources viz. geothermal energy, wind energy, hydropower, biomass, and solar energy, have been considered in this paper. The focus of this review paper is on exploring how remote sensing and GIS-based techniques have been beneficial in exploring optimal locations for renewable energy resources. Several case studies from different parts of the world which use such techniques in exploring renewable energy resource sites of different kinds have also been included in this paper. Though each of the remote sensing and GIS techniques used for exploration of renewable energy resources seems to efficiently sell itself in being the most effective among others, it is important to keep in mind that in actuality, a combination of different techniques is more efficient for the task. Throughout the paper, many issues relating to the use of remote sensing and GIS for renewable energy are examined from both current and future perspectives and potential solutions are suggested. The authors believe that the conclusions and recommendations drawn from the case studies and the literature reviewed in the present study will be valuable to renewable energy scientists and policymakers.

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.

Imagine that you could wave a magic wand and provide everyone in the world with easy access to clean and affordable energy. In one stroke you would make the world a far cleaner, richer, fairer, and safer place. Suddenly, a billion and a half of the world's poorest people could discover what it is like to turn on an electric light in the evening. The looming threat posed by climate change would largely disappear. From the South China Sea to the Middle East to the Arctic, geopolitical tensions over energy resources would fade away. Human health would benefit, too, as vaccines and perishable foods could be refrigerated the world over. And many of the world's most corrupt government officials could no longer enrich themselves by bleeding their countries dry of revenues from fossil fuel sales.

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.
