Environment Sustainability

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.

Current Crisis

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.

Practical Standpoint

In our study, from a theoretical and practical standpoint, the directions of green financing in various elements of the green economy were analyzed. In Russia, by the beginning of 2015, the portfolio of investment projects in the field of renewable energy sources amounted to more than 100 billion rubles. Until 2025, the Ministry of Natural Resources intends to attract about 3.5 trillion rubles in the development of renewable energy sources. In January 2019, the national project «Ecology» was approved in Russia, where 19.9% is government funding, the rest is a great potential for the development of green financing for all 11 Federal Projects, especially BAT. The article presents successful green finance projects in Russia and abroad.

This article deals with the analysis of a day-ahead generation diagram in specific part of a power network with renewable energy sources. As a renewable energy source a photovoltaic power plant was chosen. Input data for a day-ahead analysis was obtained from the database of previous measurement that was realised on the existing configuration in off-grid network at the department of authors. The simulation network was created in Matlab/Simscape Power System environment that consisted of rotating generators (for regulation of generated power due to fluctuated power generation from photovoltaic sources) and photovoltaic power plant of variable energy generation and loads. The results refer to a necessity to consider the previous measured data of the weather for prediction of future expectation of a day-ahead load diagram.
