The article discusses the selection and evaluation of energy-saving technologies for metallurgical production. Alternative energy sources are ordinary natural phenomena, inexhaustible resources that are produced naturally. Such energy is also called regenerative or "green". The article assessed the climatic characteristics, landscape, level of development of the territory of the location of the research object, analyzed the possibility of using solar and wind energy, hydropower, waste energy, low-potential energy using secondary energy resources. An engineering system based on the use of regenerative heat exchangers or economizers was proposed, which converts the heat of the exhaust gases from the electric steelmaking production into energy used for heating or hot water supply.

Keywords: metallurgical industry, electric steelmaking, alternative energy, energy saving, engineering systems, low-potential energy, secondary energy resources, heat of exhaust gases, regenerative heat exchangers, economizers
