Energy security assessment when introducing renewable energy technologies

Substantiating the criteria of choosing project solutions for climate control systems based on renewable energy sources

“…The main consumers of energy resources in Ukraine are industry (30.2 % of total energy consumption), household (32.8 %), and transport sectors (19.5 %) [1]. At the same time, over the past 5 years, the total level of the energy capacity of the Ukrainian industry decreased only by 4 %, at a decrease in total added value by 37 %, and the decrease in energy consumption volumes by 39 % [2]. Poor dynamics of decrease in power consumption volumes indicates a low level of production modernization in general.…”

“…The insufficient level of formation of scientific principles for construction and selection of energy-efficient climate control systems based on using solar energy and energy of environment remains an unresolved problem of the formation of power supply systems in many countries of the world [1,2]. Fragmentation in the choice of project solutions of complex climate control systems in premises and power supply of buildings for residential, industrial, or recreational purposes leads to an insufficient effect of energy saving of fossil resources.…”

“…When using the DEA method, any complex power supply system is characterized both by input parameters and output parameters. In power supply systems under consideration (more information on their construction is presented in [1,2]), the output magnitudes are formed in such a way that each of them characterizes the factor, which has a positive role in the total indicator of efficiency. They include, for example, energy carrier consumption, water consumption for and household and sanitation needs, specific capital expenditures, and others.…”
