Our article analyses the prospects of coal industry development in the 21st century. It is apparent that the share of coal in the world’s total energy mix is shrinking as it is replaced by natural gas, renewables, and other forms of energy production. In the same time, countries like China, Russia, but also Poland are dependent on coal as the major fuel for generating their electricity. Quite remarkably, China is using more coal to generate electricity for powering its growing fleet of electric vehicles and transport. This cycle needs to be broken in order to ensure the full transition to the renewable energy future and reducing the burden on the climate and global warming. We argue that the shift away from coal to the renewable energy is driven mainly by the growth of green energy policies and supporting actions induced by the political forces. However, it might still remain the major source of power generation in less-developed and developing economies.

In the future, the use of nuclear energy in national economy will rise. After accident at the Chernobyl nuclear power plant, staff of Fukushima 1 pay special attention to the safety of reactors, however, emergency situations are still possible. Eco-monitoring in natural and urban environments is carried out in order to determine the level of ecological pollution, including radioactive pollution. Therefore, studies in that direction are relevant and their relevancy is only increasing over the years. The aim of this study is to research migration and accumulation of 90Sr in vegetative and generative plant organs: cherry-plum (Prunus cerasifera Ehrh) tree and stone fruit species, gooseberry (Ribes uva-crispa) shrub. Objectives: 1) applying 90SrCl2 to the soil, imitating precipation (field experiments); 2) planting: Prunus cerasifera Ehrh; Ribes uva-crispa into artificially polluted by 90SrCl2 soil; 3) growing and monitoring of studied plants in the artificially polluted by 90SrCl2 soil. The level of pollution of experiment field reached 500 MBq/m2. The accumulation of 90Sr in vegetative and generative organs of trees (Prunus cerasifera Ehrh) and shrubs (Ribes uva-crispa) was researched. Experimental plots have been laid according to methodic of Dospekhov B.A. Measurements of beta-emitting nuclides activity in samples have been made using the “Progress” software on the USK “Gamma Plus” (beta-path) device. As the result of research it has been found that both plant species have been accumulating nuclides. In 2016 cherry-plum accumulated 90Sr in the bark, wood, leaves and fruits 2.0, 2.1, 2.6 and 2.6 times more accordingly than the gooseberry. As a result of the experiment, material, that can be used in eco-monitoring, was obtained to provide nuclear safety of urban properties in the territories, allocated for the construction of public and residential buildings.

Abstract Currently, around the world there is an acute question of the new energy sources’ development and implementation. It is known that the most significant of them today are oil, natural gas, coal, electricity. Oil and gas reserves are not unlimited. It is necessary to look for the alternative sources of energy [4, 5, 6, 14]. This is due not only to a shortage of basic energy resources, but to the increasing cost of their extraction and processing, as well as to an aggravation of the environmental situation in the world [1]. In search of the new sources of energy, people are increasingly turning to solar panels. This is an excellent replacement for the generators of various types, some of which may be slightly functional or potentially dangerous for a private house. The solar energy has been known for a long time, it is a subject of debate and discussion among the specialists. Some people think that this is a great prospect for the future, others are sure of the opposite, since on the one hand, solar panels do not require expenses for their operation, but the cost of this equipment is high. Some experts claim that the profit from this project will not be able to cover the costs associated with construction. In contrast, these devices can work for tens and hundreds of years, therefore, with long-term operation, the profit will be obvious [4, 5, 6, 11, 14].

The article presents the data of International Renewable Energy Agency REN21 and Institute ofr Environmental Technologies AEF INTEC (Austria). In 2020 in electricity production hydroenergy topped (1170 GW, 4370 TWh), then wind enegy (743 GW, 1743 TWh), solar energy (708 GW; 901 TWh), bioenergy (602 TWh), geothermal energy (14 GW; 947 TWh).

The study also describes the state of the Russian market of renewable energy, and the role of the government in its development. There are presented the results of 2020 for small hydro energy (1182 MW), solar thermal (70 MW), geothermal energy (electricity ��� 84 MW and 428 MWh/year; heat ��� 110 MW and 280 MWh), bio-generation (electricity ��� 65.2 GWh and heat ��� 25.7 TWh).

Buildings and structures are erected on the foundation of ground or arranged in the soil column, and the subsoil can also be used as a building material. Its stability, durability, reliability and appropriate operation are determined not only by the structural qualities of the structure, but also by the properties of the foundation soil itself and the conditions of interaction between the structure and the foundation. Insufficiently studied engineering and geological conditions at the construction site, poorly designed bases and foundations, failure to considerably increase the weight of the building during its reconstruction or technical re-equipment, when erecting new buildings near the existing buildings, often cause their unacceptable deformations which can cause damage and sometimes even complete destruction of the erected buildings. The improvement of design and technological solutions in the field of foundations and foundations will result in saving both labor and material resources, and will reduce the construction period. This paper studies the properties of unstable soils, various difficulties in the design and construction of buildings and structures in special soil conditions with unstable structural relationships, the analysis of a variety of methods to strengthen the foundation soils and ways to combat deformations of buildings and structures.

For a more successful formation of industrial production systems, an effective system for managing intellectual capital, knowledge and information is needed. An indispensable condition for the development of modern industry is the creation and use of information and knowledge. Industrial modernization requires an organizational and economic mechanism for resource management. When solving the problems of improving and technological development of production systems of industrial enterprises or business groups, a method for selecting a strategy for managing corporate information resources was developed. It is based on the consequences of economic monitoring of the state of the production system, which provides for the primary processing and assessment of the reliability of the results, creation of alternative predictive scenarios for changes in the state of the external and internal environment of the production system, expression of strategic goals and objectives of modernization, development of target criteria for achieving the results of modernization, alternative competing strategies for information and knowledge management, checking competing strategies against the target criterion, choosing a strategy to be applied in the improvement process. The transition to promising paths is permissible only under the condition of intensive modernization of industrial enterprises, carried out on the basis of those technical and economic decisions that will lead to the development and use of the latest NBIC technologies.

Land use in accordance with its intended purpose is important part of land management, both in the municipality and in the country as a whole.

And also allows you to solve the problems of efficient and rational use of land resources. Therefore, the study of the state of the land fund and the prospects for its use is relevant

The problem of preserving the architectural heritage as one of the most important priority tasks of our time is considered. Separate illustrations of the historical buildings of Krasnodar with the protected status of cultural heritage are presented. The need to take urgent measures for the rational use and exhibition of architectural heritage from an environmental point of view was noted. On the basis of the analysis carried out, the concept of "greening of monuments" is disclosed, which includes both the simultaneous preservation of architectural and urban planning monuments, and the natural environment. Much attention is paid to the choice of materials, replacing them with new ones without reducing their historical and artistic and aesthetic value for the restoration, repair and restoration of individual parts of architectural heritage objects. Special attention is paid to the strategy for preserving this heritage, identifying the main issues in the context of creating a comfortable living environment.
