"To manage a company means also being responsible for the ecological sustainability. Management of resources is as important as industrial management."

The importance of geothermics for heat and power generation is constantly increasing:
by the end of 2009, there were globally 50.6 gigawatts of thermal capacity and 10.7 gigawatts of capacity for power generation installed.
This is an increase of 60 per cent 20 per cent compared to five years ago, respectively.

Germany has a top position regarding the installed capacity for heat generation with almost 2.5 gigawatts of thermal capacity.
Regarding power generation, Germany is only at a bottom position, as only few megawatts are installed.

Even though the portion of geothermics of power generation is still relatively small in Germany, the prospects for growth are excellent.
According to a prognosis of the German Renewable Energy Federation BEE, the installed capacity is expected to be already at 625 megawatts in 2020 (right now, there are only 8 megawatts installed).
The heat supply will then be at 26.5 terawatt hours (TWh), of which slightly more than half comes from deep geothermics. In 2009, it was only 3.5 TWh

Drill depths of 100 meters are enough to use geothermal energy for heating and water heating. Sensitive rock strata at a great depth are not involved.

Near-surface geothermics means that the geothermal energy is extracted from the near-surface area of the earth (most often 150 m, 400 m max.), for example with geothermal heatcollectors, borehole heat exchangers, groundwater drilling or energy piles. Heat storage is also becoming increasingly important. Near-surface geothermics is solely used for gain and storage of heat. As near-surface geothermal energy is at temperatures below 20 °C, it can also be sued for cooling

The investment in renewable resources was much higher in comparison to conventional resources, like gas or oil.

But: compared to natural gas, around 48 tons of CO2 can be saved each year for the heat consumption with the heat pump.
