Abstract

World economic development is accompanied by an increase in the consumption of energy resources, whose potential reserves are limited. Assessments given in show that every 25 years, energy consumption in the world doubles and environmental problems increase as well. In industrial processes, a large amount of spent energy is often lost as waste heat, which is generated as a by-product and released into the atmosphere. The Global Energy Review notes that energy consumption in the form of heat released into the environment in both the USA and EU-27 is approximately 60% of all clean primary energy consumed. Currently, to reduce the global demand for primary energy, the use of energy-saving technologies is fast-growing in many countries of the world instead of direct combustion of coal, oil and gas involving low-grade coolants and environmental heat. This paper discusses low-temperature energy-saving technologies in heat and power supply systems. A technical and economic assessment of these areas is given. The results of using low-boiling liquids for power generation on the basis of hot Earth strata are reported.
