How much does it cost to use geothermal energy?
Installation for geothermal heat pumps does have a high upfront cost. There are a lot of variables–where you live, the ground to be drilled, the square foot of the house–and though everyone agrees about its high initial expense, exactly “how much” remains vague at best. A good general idea for cost would be twice the price of a regular heat pump system with air conditioning. A geothermal heat pump costs about $2,500 per ton of capacity, with the typically sized house needing a three-ton unit and putting the cost at roughly $7,500. Installation can bump the costs up to $10,000 or more depending on depth of pipes, type of equipment, and soil conditions. For much larger buildings and projects, costs can soar much higher.
