Exergy Analysis in Environmental Protection – Principles

Abstract

The consequences of energy conversion processes on the environment, e.g. climate changes and fossil fuels reduction have drawn more attention to the protection and preservation of the environment. Eventually, it is necessary to consider energy consumption and depletion of natural resources, i. e. the efficiency of the processes, the assessment of emission and reduction of its effects to the environment, as well as the development of new and less harmful technologies and sustainable energy resources use. Exergy efficiency is proposed as an indicator which includes the aspects of energy efficiency and environmental impact of the energy conversion processes, e.g. reduction of harmful impacts and environment degradation.
