Evaluating the technical and environmental capabilities of geothermal systems through Life Cycle AssessmentEvaluating the technical and environmental capabilities of geothermal systems through Life Cycle Assessment Ανασκόπηση Review 2023-09-072022enIn these days of heightened environmental consciousness, many countries are shifting their focus towards renewable energy sources for both large-scale uses (such as power plants that generate electricity) and smaller-scale applications (e.g., building heating and cooling). In this light, it is not surprising that there is a growing interest in technologies that are reliant on non-conventional sources of power, such as geothermal energy. This study is making an effort to provide a comprehensive understanding of the possible advantages and multiple uses of geothermal energy systems, in the context of their technical and environmental evaluation through Life Cycle Assessment. A brief description of the analyzing methods and the tools used to study a particular system or application is presented. The geothermal technologies and the applications of specific systems are discussed in detail, providing their environmental advantages and their technical barriers as well. District and domestic heating systems cover a significant fraction of the geothermal energy potential. The majority of the discussed studies cover the electricity production as the most important application of geothermal energy. The overall conclusion of the current work is that geothermal energy is an extremely viable alternative that, combined with other renewable energy systems, may mitigate the negative effects of the existing energy mix worldwide.http://creativecommons.org/licenses/by/4.0/Energies1515Milousi_et_al_Energies_15(15)_2022.pdfChania [Greece]Library of TUC2023-09-07application/pdf3.9 MBfree Milousi Maria Pappas Athanasios Παππας Αθανασιος Vouros Andreas P.
