geothermal receives a bad report

At one time if you had asked me what green building technologies do I recommend, I would have put geothermal heating and cooling systems on the top of the list... especially for buildings in Ohio. The system does work and does provide significant energy savings after all. In order for me to fully buy into a building technology such as geothermal, I would have to believe that this would be a great idea for all buildings. As such, I can no longer endorse geothermal.

Geothermal technology no longer consists of simply harvesting energy from the earth and underground water resources. The energy-efficient technology consists of a specialized furnace that circulates water through buried tubing to supplement the conventional source of either heat or coolness to achieve the optimum human comfort temperature.
