There will be less fossil fuel, which will be more expensive in the future. The regenerative energies are becoming more and more important. The subject deals the problem of economical feasibility of geothermal energy systems. Its goal is to analyze necesary conditions and aspects of realizing geothermal energy systems in comparison to and competition with traditional energy sources. The geothermal energy recovery is economically advantageous if the investment costs, esp. the drilling costs, could be reduced significantly. It only seems possible to open up a big opportunity for realizing geothermal energy systems by using a rock melt drilling technology, to reduce the investment costs significantly.}, language = {en} }
