Документ Criteria for Evaluation of Efficiency of Energy Transformation Based on Renewable Energy Sources(Economic Laboratory for Transition Research, Podgorica, 2018) Nitsenko, V.; Mardani, A.; Streimikis, J.; Shkrabak, I. V.; Klopov, I.; Novomlynets, O.; Podolska, O.; Шкрабак, І. В.In the context of shortage of natural resources in Ukraine, the prob-lem of evaluating efficiency of the implementation of renewable energy sources (RES) becomes of particular importance and comes in first place, since its solution will reduce the energy dependence of the state. Theoretical, methodological and practical issues of diver-sification of energy sources and evaluation of their effectiveness have found their development in modern works of domestic and foreign scientists. However, methods proposed by the scientists for evaluating efficiency of the transformation of energy consumption based on RES are purely theoretical and do not fully allow to deter-mine the current state and directions of diversification of energy sources. The research is aimed at improving methodological support and developing criteria for evaluating the efficiency of energy con-sumption transformation based on RES. The article considers the main methods of evaluating efficiency of involving RES in the energy consumption of the state, region and enterprise. Advantages, draw-backs and perspectives of diversifying energy sources based on RES are shown. The system of criteria for evaluating effectiveness of energy consumption transformation based on RES is proposed. It is based on economic, environmental and social efficiency.Документ Management of the sustainable development of machine-building enterprises: a sustainable development space approach(Publisher Emerald Publishing Limited, 2021) Latysheva, O. V.; Rovenska, V. V.; Smyrnova, I. I. ; Nitsenko, V.; Balezentis, T.; Streimikiene, D.; Латишева, О. В.; Ровенська, В. В.; Смирнова, І. І.The paper embarks on the development of theory and methodology for managing the sustainabledevelopment of machine-building enterprises through the use of quantitative modeling tools. The articleproposes an algorithm for estimating the position of an enterprise in its competitive space for sustainabledevelopment.Design/methodology/approach–The three dimensions of sustainability (social, economic, environmental)are represented by the equations based on the multiple criteria of sustainability. The three-dimensional space isconstructed and the effects of managerial decisions can be quantified in terms of the latter space.Findings–The proposed model is applied in the case of Ukrainian machinery construction company. Theeffects of introduction of the environmentally friendly business strategy are assessed in the three-dimensionalsustainability space. The changes in the level of sustainability can be estimated based on the projected changesin the criteria of sustainability.Originality/value–The proposed methodology combines expert knowledge, empirical data and quantitativemethods in order to quantify the level of sustainability of enterprises. The model can be extended to includeadditional dimensions and applied to different empirical cases.
