Sustainable Development Goals

Learning Goals

Students will acquire knowledge related to geothermal energy including the realization of the potential associated with this form of energy, its use worldwide and the role it may play in the future. The course will cover the methods and processes to be developed from the exploration and evaluation of a geothermal reservoir to obtaining electric energy and direct use of geothermal fluids, with special attention to the study and use of geothermal pumps. For this, it will be necessary to review and introduce some concepts and laws of thermodynamics, heat transfer and fluids that will be used in the classes on prospecting, study of the plants and their operation, and direct applications of fluids. We will end with environmental problems that may occur due to the implementation of a geothermal plant, costs associated with the production of geothermal energy, the area needed to build a plant and the amount of water needed for the plant to work.
