Traditionally, renewable energy sources (RES) are considered the most environmentally friendly, but only the stage of their operation is evaluated. A method for the integrated assessment of the renewable energy environment sustainability has been proposed, taking into account their entire life cycle - from the extraction of natural resources for the production of a power plant to its utilization. An impact assessment of RES different types on the environment has been carried out in four areas: consumption of natural resources, pollution of water resources, pollution of the soil and pollution of the atmosphere. The comparison of the considered environmental components has been carried out on the basis of an environmental pollution economic assessment at the stages of the RES life cycle. Studies have shown that the life cycle of a solar power plant makes the greatest contribution to environmental pollution, but the mini-hydroelectric station - the smallest.

The article is devoted to the problem of an environmental-economic assessment of consequences of using renewable energy sources. The existing system for assessing environmental-economic consequences of energy production can be applied only to traditional energy sources — combined heat and power plants (CHP plants), thermal power plants (TPP), and atomic power plants, since it is unviable to apply it for renewable energy sources. The reason lies in the peculiar features of renewable energy sources — they do not use exhaustible energy resources for the purpose of energy generation and have a small minimum size of a power station, which makes renewable energy sources more mobile and available for the use in the private sector of economy. This article proposes a methodology of an environmental-economic assessment of the consequences of energy generation from renewable energy sources, which takes into account the features of renewable energy sources use in comparison to traditional ones. In this paper, we analyze shortcomings of the existing methodology for assessing consequences of harmful substances emissions into the atmosphere and propose our own methodology. It includes a life cycle theory of an energy product, which allows to identify environmental-economic consequences at every stage of the life cycle of an energy product and to assess them. For an objective assessment we used statistical data and existing calculations from domestic scientists on a correlation between the number of diseases and volume of harmful substances emissions into the atmosphere. The methodology allows to assess and compare environmental-economic consequences of the development of a particular energy source in relation to other sources. Despite the generally accepted opinion that there are no environmental and economic consequences of the use of renewable energy sources, this paper proves that renewable energy sources have such an impact at different stages of their life cycle. Research findings and calculations in this paper allow to use existing mathematical tools to develop optimal models for the energy sector development of Ukraine. The proposed methodology can be applied to other countries in order to identify its shortcomings and develop further this methodology of assessment.

The current energy scenario should be examined from a global perspective and include models for optimizing the development and development of major renewable energy sources. The complex structural elements of such models in terms of the structure of energy consumption should include economic and environmental benefits, as well as minimize costs and negative consequences. At the current crisis stage, access to energy sources is an important asset for economic progress and world development of all states. The depletion of natural resources, ecosystem and climate change lead to the need for scientific research in the field of sustainable development and the use of various models of energy conservation to achieve social and economic growth. Renewable energy sources such as solar, geothermal, wind and others are the basis for the development of new concepts and models for economic optimization and renewable energy. The key role in the implementation of such models is played by maintaining the ecological balance and renewing energy using natural and natural resources.

The paper shows that a comprehensive intersectoral approach is needed to address the issues of systematic management of energy saving in agriculture and to justify rational measures of economic support for the state-initiated introduction of energy-saving technologies, machines, and projects. Such requirements are met by the energy-economic (bioenergy) assessment method. The energy-economic assessment consists in comparing the costs of cultivating plants or servicing animals in single units of measurement with the production results and is mainly of national strategic importance. On the basis of such assessment, economic guidelines and incentives for the introduction of new energy-effi cient technologies, machines and projects, including the use of renewable energy sources, can be developed. The author presents an approach to improving the methodology of energy-economic assessment of agricultural technologies and projects when using renewable energy sources in technological processes. It is proved that in order to ensure the reliability of the energy-economic assessment associated with permanent technological and organizational changes and the digitalization of technology and economy, it is necessary to continue research to improve the assessment methodology, as well as clarify and regularly update energy equivalents.

Battery electric multiple units (BEMU) are an effective path towards a decarbonized regional rail transport on partly electrified rail lines. As a means of sector coupling, the BEMU recharging energy demand provided through overhead line islands can be covered from decentralized renewable energy sources (RES). Thus, fully carbon-free electricity for rail transport purposes can be obtained. In this study, we analyze cost reduction potentials of efficient recharging infrastructure positioning and the feasibility of covering BEMU energy demand by direct-use of locally produced renewable electricity. Therefore, we set up a model-based approach which assesses relevant lifecycle costs (LCC) of different trackside electrification alternatives comparing energy supply from local RES and grid consumption. The model-based approach is applied to the example of a German regional rail line. In the case of an overhead line island, the direct-use of electricity from adjacent wind power plants with on-site battery storage results in relevant LCC of EUR 173.4 M/30a, while grid consumption results in EUR 176.2 M/30a whereas full electrification results in EUR 224.5 M/30a. Depending on site-specific factors such as existing electrification and line lengths, BEMU operation and partial overhead line extension can lead to significant cost reductions of recharging infrastructure as compared to full electrification.

The article deals with the economic evaluation of investment and optimization of the renewable energy sources for family houses. For example, from the point of view of solar systems, the optimal solution is based on the specific application of it. The design is dependent on the location of the panels and ration between active aperture area and real daytime consumption. Common calculations according to actual standards often give overstated results, which also reflected in the value of the investments. The article shows the research of optimal parameters of the thermal solar system for preparing of domestic hot water. A combination of related standards and software TRNSYS are used to find optimal parameters. Thanks to created and verified simulation models, it is possible to design parameters so as to avoid under-dimensioning or over-dimensioning of the each system. Energy price is another factor affects the payback period of investments. This is affected by the used energy sources and their combination. For example, buildings that use electricity to heat water or heating have different energy charges than a building that uses natural gas. So, the aim is to find optimal solution of the combination of renewable energy sources.
