The aim herein is to identify and analyze the public awareness and acceptance mechanisms for the successful deployment of geothermal investments in Canakkale using geological, social and economic constraints in a well-defined questionnaire. The study employed a sequential explanatory survey to explore public perception and acceptance. The research results show that the geothermal energy resources in the Biga Peninsula, in particular, have significant potential for different uses; however they indicate that there are insufficient knowledge levels related to both what geothermal energy is and its environmental effects.
