Geothermal energy is produced by extracting the heat of the earth’s crust using water/steam from wells in open systems with an aquifer and hot convective zone. It is used for heating, cooling and power generation in greenhouse production, aquaculture and health spas. Scalable, on-demand heating/cooling is also achieved using a closed-loop system that circulates fluid contained in subsurface pipes. CanGEA recently completed a feasibility study to implement geothermal resources in place of diesel in Nunavut communities.
