Which chances does Goethermal Energy offer?
6.000 °C
Our Earth:• > 98 %:
hotter than 1.000 °C
• < 0,1 %colder than 100 °C
• quasi-infinite• basically everywhere available• base-load suitable• decentral

Dipl.-Ing. Frithjof Clauss • Institute and Laboratory of Geotechnics
For heating and cooling purposes energy can be extracted from or stored in the subsoil by e.g.:
• Borehole heat exchangers
• Ground loops
• Energy Piles & other earth-contacting massive absorbing elements
• Groundwater wells
