Along with the extensive use of classical energy keys in modern society, efforts are being made to integrate so-called non-traditional (or alternative) energy sources into the economic circulation. The article examines the types of alternative energy sources, their advantages and disadvantages in relation to the climatic and geographical circumstances of the territory. Annotation. Along with the extensive use of classical energy sources in society, efforts are being made to integrate so-called non-traditional (or alternative) energy sources into economic circulation. This article discusses the types of alternative energy sources, their benefits.

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.

The cause of many environmental problems currently discussed may be imputed to current standard of production and consumption of energy, which is not consistent to the sustainable development's concept. On the other hand, energy is a key element of modern society and, without an adequate supply, its development will be limited. Thus, it is clear that the demand for energy, particularly in development countries, shall grow in coming years; so it is up to policy makers to develop mechanisms and encourage a transition into renewable (or sustainable) energy sources. At that point, the Environmental Law must operate along with the policy makers, by coordinating the necessary means to achieve predetermined goals, through public policies and programs - which are generically composed of command and control instruments and economic instruments. This study aims to illustrate those challenges with the discussion of two public programs implemented in Brazil for those purposes: "Light for All" and "Program of Incentives for Alternative Energy Sources" - PROINFRA.

Research has been performed on the state of development and trends for alternative energy sources. Advantages and disadvantages of renewable energy have been considered. Main types of the effects due to the implementation of renewable energy sources have been investigated. Main aspects of the actual effects upon society as a whole have been determined, in order to perform the objective assessment of the social efficiency of implementation of renewable energy sources. Methods to determine the social and economic efficiency of using the renewable energy sources have been suggested.

Use of alternative energy sources is one of the promising directions in economic and environmental development of any territory. The purpose of this article is to conduct geo-information analysis of the insolation level within Ivano-Frankivsk region located in the western part of Ukraine. When considering any research territory, it is worth conducting a factorial analysis, which gives the possibility to characterize any advantages and disadvantages of the use of alternative energy. Justification of approaches to the study of territories where alternative energy sources are located or generated is needed to create a unified system for assessment of the potential of the renewable energy sources. Ac- cording to data of the European Space Agency, the insolation level on the research territory varies from 1175 to 1425 kW/hour* sq. m/per day. The method of our research involves the statistical analysis of the insolation level and the factor approach to determining the existing level of insolation Insolation values, meteorological and geomorphological factor characteristics are used to substantiate the new methodology for calculating the existing insolation level. According to the statistical analysis and geo-information analysis, this reasonably permits us to structure months by the level of insolation as well as to calculate the insolation level at a specific point for a certain time of year. Taking into account the angle of inclination above the horizon – the Sun’s declination, the slope exposure – the Sun’s azimuth gives us the possibility to reduce the value of the relief point with its selected factor characteristics and the insolation value to the single coefficients, which permits us to clarify the information as to the insolation level of the selected region. Finally, this is resulted in creation of a map with the isolation levels for Ivano-Frankivsk region taking into account the factor characteristics. The map represents the changing of the insolation level for seven grouped months. It should be noted that insolation level is uneven and it is characterized by the widest gradation within the territories with complex relief. In that event, the optimal angle of solar photovoltaic module inclination equals 49° within Ivano-Frankivsk region. Such structuring clearly reflects the dynamics of changes in the insolation level for an individually selected zone. The scientific novelty of the obtained results is assessment of distribution of the solar energy potential required for further selection of areas to design and locate the solar power stations. The practical significance lies in obtaining the digital cartographic materials which allow assessment of the insolation value at a specific point in the studied region. Structuring of the insolation maps gives the possibility for further development of a unified insolation assessment scheme that is convenient for any user.

In modern society, both from an economic and ethical point of view, the most relevant issue is the use of alternative energy sources, since it is obvious that the reserves of organic fuel are exhausted, and their exploitation leads to significant damage to the environment. The main types of alternative energy today include hydropower, wind energy, and solar energy. In some countries of the world, it is possible to develop wave and geothermal energy. In this article, the author attempts a scientific analysis and critical understanding of the prospects for the transition to alternative energy sources with consideration of issues of energy efficiency and energy conservation.

The increasing demand for air travel leads to more pollution produced by air transport. At the same time the fuel prices are constantly rising. Therefore, it becomes necessary to find alternative energy sources for aircraft (alternative fuel, motors). In this article alternative propulsion systems (fuel) that can be used in aviation, their advantages and disadvantages are reviewed.
