Abstract

Considering the risk of reducing fossil fuels in the near future and increasing environmental pollution problems, human societies are now struggling to change their supply and demand patterns. With the advancement of technology, the use of renewable resources is considered as a reliable alternative to fossil fuels. Therefore, the role of geothermal resources as one of the most important sources of renewable energy is notably discussed. This energy is introduced as a sustainable resource, with the potential of adaptation as an alternative to fossil fuels. This paper examines the application of geothermal energy in agricultural applications in the world and Iran. At the same time, geothermal energy and its applications are introduced in various sections, especially greenhouses. Then, the conventional parameters and methods of geothermal energy design for use in greenhouses are presented. As a result of these studies, it was determined that 5 methods for heating greenhouses and 2 methods for greenhouse cooling were considered, which should be selected according to the requirements of the applicant unit and the regional conditions. Finally, the situation in Iran is evaluated in utilizing geothermal resources in the agricultural sector.
