Geothermal energy is being investigated as a renewable source of electricity and heat production for communities in northern Canada. The successful development of a geothermal energy project requires three key components: (1) there must be a source of sufficient heat at near-surface depths. Typically, geothermal projects require temperatures of at least 150°C for efficient electricity production while lower temperature resources can be directly used for heating, (2) the rock must contain pore fluids that can be used to transport the heat to the surface through pores, fractures, and boreholes, (3) the host rock must have sufficient permeability such that fluids can move easily through the subsurface in pores and fractures. The community of Watson Lake, Yukon may be a potential site for a geothermal energy project. Studies have show that the area surrounding Watson Lake has high values of surface heat flow and temperatures that may exceed 200°C at depths of 6 km below the surface (Majorowicz and Grasby, 2014). ...
