Globally increased energy requirements indicate the necessity for introduction of energy saving measures, necessity for applying energetic efficiency as well as more active usage of sustainable energy sources in production of the electricity. One of the possible ways to introduce sustainable energy sources certainly are systems for production of electricity which are based on energy of the Sun and on the wind energy. Because of intense stochasticism of the nature of primary energy sources, there certainly is present the need for their optimization. Thereat, the technical capacities are in dependence with available wind and Sun potential, so with the needs of observed consumer or with possibility to sell the energy inside the program of obligatory redemption. Inside this paper the analysis of optimal usage of the wind energy and the energy of Sun by virtue of hybrid systems in terms of supplying small consumers on Banjaluka region with the electricity is given. The research was performed by methods for predictive analysis of primary energy sources and their combinations, and so by the algorithm for defining optimal ratio of certain forms of energy according to accepted technical and economic criteria (the lowest price of electricity produced by the hybrid system, availability of the energy, etc.) The resulting data is in compliance with Banjaluka region. The performed method for optimizing and economic-financial analysis has confirmed construction justifiability of systems based on wind and Sun energy.
