This article shows the efficiency of utilization of low-potential waste energy on various examples in the energy industry. First, the choice of the technology of organic Rankine cycle as a technology of utilization or conversion of low-potential energy is justified. Secondly, requirements to the working bodies used in this technology are formulated. Third, the proposed options for combining this technology and: solar energy; bioenergy; geothermal energy, as well as the superstructure of the organic cycle for heat recovery from the gas turbine and hot water boiler, with an assessment of the potential of the implementation. Examples of implementation of this technology by major manufacturers around the world are presented.
