I don't know the area; but gather it's hydro territory?If you drill a vertical hole in the order of 50-200 meters deep, the cooling effect of water pumped through a pipe in that hole is in the order of 50W/m. So you can lose 10kW of heat into 200 meter hole. Not sure what the separation needs to be for this to be sustainable. Pretty good return on investment, considering drilling a hole is $3k-$6k.How about water-source heat pumps? It's lots easier to cool 25C air into say 10-15C water than into 30C outside air. Open loop water source systems do have their issues [algae, etc] but can save a lot of power....
