Abstract:

Energy, which has an important position both in the world and in Türkiye, is essential for many primary areas, such as heating-cooling and production. After the industrial revolution, replacing simple machines with steam engines started the adventure of energy dependence and gave strategic energy importance. This situation has played a critical role in reshaping human history. In addition, due to the limited fossil energy resources and the continuous increase in energy costs, countries have started to develop new energy policies for their interests. Thus, scientists have accelerated their work in the field of energy efficiency. District heating systems, one of the best examples of renewable energy use, are the main subject of this study. District heating can be defined as the heating of a building, neighborhood, or city with power plants installed in one or more centers. This study aims to calculate the financial benefit of the district heating systems to be created with the use of geothermal resources in Türkiye to the Türkiye economy and its contribution to the goals of carbon neutrality. As a result of the use of a geothermal-sourced district heating system, a 1.58% reduction will be achieved in Türkiye's annual greenhouse gas emissions. With current investment amounts, the amortization period of 1,000,000 residential equivalent geothermal sourced district heating system implementation is approximately 13 years. Numerical methods were used in this study.
