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

Italy is a country where the energy supply depends largely on imported raw materials (such as oil and natural gas). The favorable geographic location could encourage the development of renewable energy sources; nevertheless, the growth of alternative energy sources is slow. What are the reasons? This question will be dealt in this chapter, considering three different aspects of the issue: the economic incentives for renewable energies, the problematic process of authorization of the facilities and the local communities’ opposition to new plants. Besides the analysis of these issues, the aim of this paper is to identify possible solutions, taking into account the relevant legislative and regulatory changes that, at national and Community level, have affected and are affecting the field of renewable energy.

Today, almost all of civilisation is based on energy. To a large extent, energy is being continuously acquired from non-renewable raw materials deposited in the Earth’s crust. Renewable sources provide alternative, infinite energy resources, particularly solar radiation, wind power and water movement. The Paris Agreement envisages the complete abandonment of fossil fuels by the year 2050 for all EU Member States. From a technical point of view, a complete transition to renewable energy sources (RES) is very difficult to achieve. In the case of Poland, the way to 100% RES is longer and more complex than in most EU countries. The main purpose of the conducted analysis was to thoroughly assess the possibilities for obtaining energy from inexhaustible sources as well as the benefits of various procedures in order to develop an optimal set of solutions. The aim of the presented study is to indicate the possibilities for the development of construction investments in the field of renewable energy sources that have an inseparable impact on spatial management. To achieve this aim, the method of research of the available literature and legislation was applied.

In Slovenia, there is an urgent problem of limiting the harmful effects of economic activities that deteriorate the living conditions of people, animals and fl ora. The state is taking measures to encourage residents to stay in their home towns and take care of their arrangement and development, the preservation of natural resources and a comfortable environment for people. Numerous public organizations of civil society play an important role in this. This article outlines the features of the modern environmental policy of Slovenia, carried out within the framework of the general line of the European Union, aimed at the phasing out of carbon fuels and the transition to renewable energy sources. The article analyzes Slovenian official documents, setting out the country's environmental strategy, progress in the implementation of plans for energy and climate measures until 2030, the current state of the energy sector and its compliance with the planned tasks. The author's assessment of the efficiency of the environmental policy carried out in Slovenia and its possible results is presented. It is stated that although the indicators of improving the environmental situation are gradually increasing, the emission of harmful gases is decreasing, and the efficiency of the use of energy and raw materials is improving, Slovenia still lags behind the European average in most of these indicators. Meanwhile, it has a relatively high share of renewable energy sources in its total production. This is achieved through budget subsidies for the energy produced from renewable energy sources so that its price does not exceed the market level. Significant monetary resources are spent to apply a wide range of incentive measures. Therefore, the government is forced to seek opportunities to further increase the funding for environmental activities, in particular through European Union funds, including assistance to fight the coronavirus pandemic.

To increase the security of energy supply, it is essential to search for utilization alternatives of renewable energy sources. The fermentation of organic material is more effective if the substrate is subjected to pre-treatment. In order to avoid toxic byproduct in the course of pre-treatment, a mechanical method was preferred. In this paper, the behavior of agricultural raw materials subjected to mechanical disintegration is examined. The pre-treatment of substrate was carried out with a comminuting machine which is normally used in industrial sewage fermenters in Hungary, but in agricultural biogas plants it has not been built in the technological process yet.

The article discusses the importance of marketing in the market of renewable energy sources. Alternative energy and its development significantly depend on the country and the climatic conditions of a particular area. In Russia, alternative energy, its development, lags behind world leaders. There are several reasons for this. The first reason is the large reserves of fuel and energy raw materials and their low cost. The second reason is the low utilization rate of the installed capacity of alternative energy. The third reason is that the weather conditions in Russia are nonhomogeneous and not very suitable for the development of alternative energy. A promising direction for the development of alternative energy is small alternative energy. Marketing is built on effective market segmentation, increasing end-user awareness and customer education efforts. The article also provides recommendations for improving the effectiveness of marketing, its special features, taking into account altruism, paternalism and moral satisfaction ofcustomers.

Development Analysis

The use of renewable energy sources (RES) has increased exponentially worldwide, as an alternative to the indiscriminate use of fossil fuels and to mitigate their effects on the environment. Cuba is not lagging behind in this development since the government’s plan until 2030 includes the contribution of renewable sources as a fundamental component in the national energy mix. This paper models possible scenarios based on 2019 statistics for achieving a 25% and 100% penetration of renewable sources by 2030 in the Isla de la Juventud’s (an island south of the main island of Cuba) electrical power system (EPS). This modeling is carried out utilizing and open source Excel-based accounting framework Long-range Integrated Development Analysis (LINDA). For this purpose, international and national trends in the use and development of renewable energy sources and the influence of the characteristics of each renewable source (wind, solar, biodiesel, battery storage) were analyzed. The analysis of Isla de la Juventud’s electrical power system was based on the characteristics of its energy mix, the possibilities of renewable energy penetration and the current and future energy demand by sector. Based on the analysis, two probable scenarios were modeled with LINDA model: a 25% renewable energy-based scenario (RENES) and a 100% renewables-based scenario (MAXRES). Results from RENES and MAXRES scenarios show high penetration of renewable energy sources in electricity generation is theoretically possible with the abundance of renewable energy resources, and thus it is possible for Cuba to move towards 100% renewable energy mix. However, the choices regarding the best fit energy mix need to be carefully analyzed in order to design a least cost system that answers the needs of the future demand.

In this study, energy utilization of biomass is introduced with a short description of renewable energy sources and utilization possibilities of biomass.Presently, the necessity of renewable energy sources is increasingly obvious. Among renewables, energy from biomass is to be highlighted, since this allows versatile, cheap utilization of the sun’s energy. In this respect, Hungary has advantages. Direct heat utilization and biogas production are available procedures today, whereas biodiesel and bioethanol are expected to spread in the near future. Biogas production is possibly the most versatile method for biomass conversion: it can produce energy from materials inapplicable for other utilization; at the same time, it is capable of neutralizing harmful wastes; in the end, it produces also valuable fermentative products, from bio-manure useful in agriculture, to pharmaceutical raw materials.
