28 Conclusions Geothermal energy has the potential of playing an important role in sustainable and carbon free energy supply It is suitabel for both electricity and heating/cooling In many areas of the world and espacially in Turkey geothermal energy can supply more then 100% of the base load In certain circumstances even small scale geothermal resources are capable of solving numerous local problems and of raising the living standards of small isolated communities 28
