Due to global warming large efforts have to be taken in order to find a CO2-free energy supply for private consumers as well as for industry. One of the so-called renewable energies is geothermal energy. A new geothermal power plant was built in Basel, Switzerland, in 2006. A few weeks after the first water injections a series of earthquakes occurred in the region, which seems to be connected with the pressing of water into the ground.
