Article Evaluation of Geothermal Energy Resources in Terms of Exergy Analysis(Zonguldak Bülent Ecevit Üniversitesi, 2018) Hancıoğlu Kuzgunkaya, EbruEnergy is recognized as a crucial element in a country development process. Geothermal resources are a green energy source that can make a considerable contribution in some countries. Also efficient use of resources is important due to availability, economic and environmental issues and comprises the essence of this work. The exergy analysis is a powerful tool for the design, analysis and classification of thermal systems. Using exergy for resource classification benefits their comparison, according to their ability to do work. Specific exergy index (SExI) was calculated to show for classification and capability of some geothermal area. Actual system data are used to assess the district heating system and power plant performance, energy and exergy efficiencies. In this study, specific exergy index for examined field was calculated between 0.026 and 0.947 and sustainability index (SI) was found between 1.250 and 2.782.Article Citation - Scopus: 19Application of Geothermal Energy and Its Environmental Problems in Turkey(Inderscience Enterprises Ltd., 2015) Baba, AlperHuman beings have been benefiting from geothermal energy for different uses since the dawn of the civilisation in many parts of the world. One of the earliest uses of geothermal energy was for heating and it was used extensively by Romans in Turkey. The Aegean region is favoured by a large number of thermal springs known since ancient times. However, it was first in the 20th century that geothermal energy was used on a large scale for direct use and electricity generation. The country's installed heat capacity is 2,705 MWt for direct use and 322.39 MWe for power production. In parallel to developing geothermal energy applications in Turkey, many sites are now experiencing problems such as water contamination associated with geothermal fluid. Especially, the high temperature solution of elements and compounds, causes operational limitations in geothermal power plants. These limitations are due to the severe scaling and corrosion of geothermal fluid. Copyright © 2015 Inderscience Enterprises Ltd.
