Abstract

An analysis of Ukraine’s sustainable development targets, in particular in the field of energy, resource management and environmental protection, are presented. It is shown that regional energetic is a determining factor for achieving the aims of sustainable development.

Changes in the natural environment in Ukraine due to external (global) and internal (local) factors that are intertwined and overlapped can cause threats to socio-economic development. It is proved that in the areas of mining and industrial activity a multiple increase in emissions of pollutants into the environment are observed.

The comparison confirmed the overall compliance of the structure of consumption of primary energy resources (solid fossil fuels, natural gas, nuclear fuel, oil and petroleum products, renewable energy sources) in Ukraine and in the European Union, shows a steaby trend to reduce the share of solid fuels and natural gas and increasing the shares of energy from renewable sources.

For example, in Ukraine the shares in the production and cost of electricity in 2018 was: the nuclear power plants – 54.33 % and in the cost – 26.60 %, the thermal power – 35.95 and 59.52 %, the renewable energy sources – 9.6 and 13.88 %.

The energy component must be given priority, as it is crucial for achieving of all other goals of sustainable development and harmonization of socio-economic progress.

The paper systematizes the indicators of regional energy efficiency and proposes a dynamic model for the transition to sustainable energy development of the region.

Abstract

Macro- and microcomponent chemical composition of reservoir waters of the Cambrian, Devonian, Carboniferous aquifer complex of the Velyki Mosty gas field and surface water of the Upper Cretaceous sediments are studied. Changes of basic genetic parameters of the ground water with the depth and in the space are analyzed, hydrogeochemical conditions of their origin are found and the coefficient of the hydrogeological closing of bowels is calculated .

Formation waters of the Cambrian and Devonian complex have high salinity, low sulfurity and chlorine-bromine factor and belong to the chloride-calcium type with high degree of the metamorphism. Groundwater of the Carboniferous period is characterized by lower salinity, high sulfurity and hydrocarbonate-sodium type. It was found that Cambrian and Devonian aquifers are zones of delayed water exchange according the coefficient of closing of structures and Carboniferous aquifer is a zone of considerable water exchange.

Surface water of the Upper Cretaceous sediments are unleavened, slightly alkaline with hydrocarbonate calcium composition. High values permanganate oxidizability in the waters of the river indicate the impact of the technogenesis. Hydrocarbonate calcium composition of drinking water from Senon-Turonian horizon of the Upper Cretaceous indicates no impact of deep water.
