> What happens when you heat the ground and the water in it evaporates? What happens when you cool the ground and the water in it freezes? What happens to indigenous vegetation if you're messing with the ratio of air temperature to ground temperature all year? Ground source geothermal has been deployed for decades without negative environmental effects. The ground a few meters down (where ground source loops are placed) is a huge thermal mass, whose seasonal temp varies little, and space heating/cooling of buildings is not a significant enough force to overcome its inertia. It is alao deep enough to have little effect on the air to ground temp ratio. The biggest factor in that ratio is the variance it weather itself. The ground source loops is highly localized near the building. Putting up the building and the road to it was probably more damaging to indigenous vegetation than anything the heat pump would do.
