The article is aimed at determining the opportunities of the regions of Ukraine for self-sufficiency in energy resources, improving energy security and energy efficiency, as well as forming a methodological approach to determining regional ratings by the level of energy efficiency and energy security. The indicators of energy efficiency and energy security, proposed in the article, is advisable to use as a base for a further system of indicators, applied to determine regional ratings of energy efficiency and energy security. The proposed indicators allow to comprehensively assess the level of energy security in the region, are relevant and can be easily calculated using data from the State Statistics Service of Ukraine. To assess the level of energy efficiency and energy security of the regions of Ukraine, it is advisable to use the author’s own methodology, which also allows to assess the availability and quality of energy resources use. The application of the proposed two-level system of indicators and the method of their calculation allows solving the problem of informing different categories of users about energy efficiency and energy security of the regions in order to determine the need for control influences in conditions of limited information. Based on the results obtained, both the State and regional administration bodies together with local self-government bodies will be able to assess the results achieved, compare them with the achievements of other regions and develop a system of measures to improve the energy efficiency of the regional economy and ensure energy security in the future. Further researches of the author will be aimed at calculating on the basis of the formed methodological approach of the rating of energy efficiency and energy security of the regions of Ukraine, carrying out a comparative analysis of the regions and developing proposals for solving identified problems, based on the rating results obtained.

The Impact

Prior to the start of any Wind Power Park construction project, it is necessary to carefully assess available wind potential in the selected area. The cost of such investigative studies is considerable – even with a relatively small 70 m tall mast it reaches several tens of thousands of Euros. In order to reduce costs related to wind speed measurements it is suggested to use the existing cellular communication masts that are widely spread in Europe. The study presents a methodological approach and the results of wind speed and wind shear measurements performed with the use of lattice cellular communication masts at the height of up to 100 m. A CFD model of airflow around a cellular communication mast structure was created in order to explore the impact of mast structure on the quality of wind speed measurements. The paper presents the results of the CFD modelling in the form of contour maps depicting the severity of airflow disturbances around the mast. The study is based on experimental measurements conducted in 2018 in three coastal sites of Latvia. At each site wind speed and direction were measured at several heights along with air temperature, humidity and air pressure. The experimentally obtained data in combination with the analysis of modelled CFD results shows the possibility of using cellular communication masts for accurate measurements of wind speed. Overall, the study shows that the proposed approach to wind speed measurements can result in high quality data and reduced overall expenses.

The article talks about theoretical provisions related to the application of agro-technological operations in agriculture, including their economic and environmental components. Monographic, abstract and logical methods, as well as methods of comparison, generalization, and analysis, are used. Results. It is established that agriculture, unlike other branches of the economy, is not only a consumer of energy, but also generates it as a finished product. This uses anthropotechnogenic energy, as well as solar and soil energy. It is emphasized that the issue of achieving positive energy balance in agriculture is relevant today and needs to be solved by reducing energy consumption from non-renewable sources. It is determined that energy saving in agriculture involves the application of legislative, organizational, scientific, productional, technical and economic measures. As a result, the balanced energy consumption, rational energy use, optimization of energy saving management through organizational and economic mechanism and reducing energy consumption should occur. It is proved that the directions of energy saving in the agricultural sphere can be determined by the processes of its circulation and manifest itself in the form of providing access to energy resources, creating competitive conditions in the energy supply market, diversifying energy resources, increasing the efficiency of technical means. Considering the tools of energy saving achievement, it is determined that its main areas are: management, energy, technology, technical and selectional measures. Together their action is aimed at reducing energy consumption of fossil origin and using the solar and soil energy optimally. Discussion. The results of the study serve as a theoretical basis for further research in the energy saving field of agriculture, which can be implemented to substantiate comprehensive actions aimed at reducing energy consumption, as well as to develop an organizational and economical mechanism capable of achieving the highest level of energy saving.
