Because this has a residential focus, teachers should discuss the capital cost of geothermal systems as they are expensive to install (Capital Cost of $20k - $35k) and costs vary depending on location/ease of drilling.

The video only addresses the lower operating costs of a geothermal heat pump. Cost estimator link:
