The goal of the finishing paper is to show establishing possibilities and the existing potencial of RES for the fulfilment of the energetic need of LSŽ. Whitin the paper it's displayed on what model the analysis about the consumption of electric energy and thermal energy whitin the period of 2015. to 2030. was built on. The energy system of LSŽ which had been baised on an existing potencial of RES has been cisplayed. The data that we have should be compared with the consumation and a financial analysis should be made regarding the manufacturing of electric energy from RES. After the analysis had been conducted the results should show the possibilities of the manufacturing of electric energy and termal energy from RES for the needs of LSŽ. The area of the country involves the area of Lika with harsh mountain climate and a narrow seciboard between Velebit and sea and a part of Pag island (Novalja) when there is mediterranean climate. Accorcling to the available data from the analysis of possibility of the development of the facilitys of RES on the area of LSŽ there are natural potentials of the energy of wind, biomass, hidroelectry energy and solar energy but natural hot springs havent been recorded. Solar energy can be used trough the usage of solar heat systems for heating up used warm water and heating up photovoltaic systems for manufacturing electric energy. The natural potentials of RES on the area LSŽ are meaningful and the usage of those potentials will lead to the usage of the best locations and the possibility of deuelopment ofLSŽ.
