Sistemas de informação geográfica (SIG) para energias renováveis

Abstract

The use of renewable energy sources in isolated households, avoiding the grid expansion, is considered viable in some cases due to economic criteria. Many aspects are considered: demand expands potential, distance of grid and appropriated technology. Each technology needs specifics analysis and demands handling databanks and projections. In Brazil ca. 12 millions people have no electric energy access; the universality electric energy programs works in a centralized way and usually regional specificities are not considered, and sometimes causes discredit to the programs. Geographical Information Systems (GIS) are tools that aim to join resource and energetic demands data about the places that will be analyzed, joining a framework of geographical information, and provides the results disposed in images. GIS allow safety and agility in taking decisions or even enhancing the results monitoring to on going programs. This paper brings an analysis of the state of art of this technology applied to renewable energy, identifies the potentials and suggests actions to apply in project and programs to renewable energy spread and uses
