The 3rd EASYGO Training Week was organised by the EASYGO Project Management team together with Politecnico Milano, between the 22nd and 26th of May, 2023, in Volterra, Italy. Whereas the first training week focused mostly on an introduction to geothermal energy, geophysical techniques for exploration and monitoring and energy conversion technologies, and the second on Computational Geosciences, Inversion methods, Open-Source concepts, as well as hydraulic stimulation and CO2 geothermal techniques, the third training week focused on technical aspects of exploration and above-ground engineering and installations. The training week was complemented with course on communication and emotions at the workplace. As in the first two training weeks, the lectures were complemented with an extensive poster session, where all ESR students presented and discussed their work with co- Principal Investigators (co-PIs) from all universities. After the poster session, a social gathering completed the training week, with additional time for discussions in a friendly and informal environment.  Additionally, this Training Week offered the opportunity to visit the first geothermal power plant in the world in Larderello, Italy.
