DEVELOPMENT OF GAMZIGRAD SPA AND INCREASING OF ENERGY EFFICIENCY

Due to the fact that man in the last few decades has significantly damaged the environment and eco-system in which he has been living and working, it is raised the question of possibility of further survival and development of the planet of Earth. As the human civilization had pitilessly spent unrenewable energy sources to achieve economic progress and development of economy, we have faced disappointing fact that there are less and less such sources, so that there is a great danger which could cause their complete exhaustion. Trying to find solution for the conditions in which he is, man has started to direct his attention to other, alternative sources of energy, so-called group of renewable sources, whose use does not endanger balance in the nature and does not damage the eco system. The Paper deals with one type of renewable energy, geothermal energy. It was calculated the energy efficiency of the geothermal well in the spa of Gamzigradska Banja if the well is used for heating the Special Hospital for Rehabilitation in Gamzigradska Banja.
