Geographical Information System Applied in Using Solar Energy Resource

Due to industrial and human activities, in the last decades there has been a depletion of fossil fuels. Therefore, a general development regarding the use of renewable energies appeared. In Romania, different initiatives at national, regional and local level on the application of solar energy have started to be supported by photovoltaic systems. In this paper, Alba County of Romania is analysed from the solar energy point of view using a geographical information system model. The aim of the paper is to demonstrate the areas in which solar energy can contribute to a sustainable region.
