Using the earth's inexhaustible heat with Deep geothermal technology.

There is great energy potential lying dormant inside the Earth. This enables us to provide affordable base-load renewable energy for local communities. Hot brine is brought to the surface from underground reservoirs and used to generate renewable energy. The geothermal power plant “Natürlich Insheim” has been reliably supplying thousands of households with green electricity since 2012.
