Understanding social acceptance of geothermal energy: case study for Araucanía region, Chile

Abstract

This research aims to explore public views and social attitudes toward the use of geothermal energy as a heating and electricity source in an area where the geothermal energy production technology has yet to be widely introduced. This case study focuses on the community that surrounds the Villarrica Volcano in the Araucania region of Chile. This area is considered to be one of the six high enthalpy geothermal zones in the Chilean Andes with the highest potential for geothermal energy production but actual production is nearly non-existent. Taking a risk communication approach, this research includes in-depth semi-structured interviews with local stakeholders. It suggests that there is a low level of understanding of the technology involved in geothermal energy production, and it highlights social barriers such as lack of trust, spiritual relationship to volcanoes, and uncertainty about environmental impact as factors that affect risk and public perception.
