Abstract: The issues relating to the environmental pollution are becoming more and more crucial as the industrialization of the third world countries runs very rapidly and the industrialized countries keep on increasing consumption of goods and electricity. The use of fossil fuels and especially coal are increasing with an alarming rate. The global warming effect is threatening our mere existence on earth, on the long run. The exergy efficiency of power plants, of any fuel, could be a measure of how well the plant is performing and at the same time how low could the emissions be. Exergy is a concept not new by any means but fairly new in its extensive use for its relation to sustainable development. The exergy efficiency as compared to energy efficiency gives a more concise picture of the performance of a power plant and is closer to its relation to the environment. In this work the issues of exergy analysis as related to the environmental impacts of power plants will be analyzed.
