[Energy in buildings](https://www.materialinsights.org/energy/e_buildings/) (energy) and [Geothermal direct use and ground-source heat pumps](https://www.materialinsights.org/energy/e_geo_direct/) (energy): 2 relationships.

## How they are linked

### 1. Energy flow

*Physical flow · 19.4% of flow · Geothermal direct use and ground-source heat pumps → Energy in buildings*

Ground-source loops heat and cool individual buildings.

- **19.4%** of Geothermal direct use and ground-source heat pumps's energy goes this way

### 2. Price link: running cost

*Cost and price · Weak · Both ways*

Heat pumps run on electricity, so power tariffs decide running costs and payback. The US electricity price and heat pump index show a weak yearly link at 0.29. Cheap power speeds payback.
