Subject and purpose of work: The aim of the work is the analysis of possibilities of using different renewable energy sources (RES) in tourism facilities and the effects caused by such installations. Materials and methods: Empirical material is formed by tourist objects of different scale of service provision in which RES have functioned for several years and the users are able to assess the advantages and disadvantages of the applied solutions. Results: It was noted that depending on the type and location of an object and the demand for energy one may select such a source and method of conversion into usable energy which to the greatest degree fulfils these needs. Solar energy deserves special attention as the greatest potential occurs during the period of increased tourist traffic. Furthermore, solar energy may be processed into heat and electric energy including island systems. Conclusions: RES installations concern energy for tourist objects which has economic and environmental impact and furthermore they constitute tourist attraction. For objects located far from electricity grid they may constitute the basic source of energy.
