Abstract
Environmental sustainability analysis of technologies for electricity generation of renewable energy sources (RES) was done using fuzzy logic, in order to compare and choose the best alternative for giving potential solutions to supply the electricity deficit in non-interconnected zones (ZNI per it initials in Spanish) from Colombia. The analysis took into account the availability of energy resources; energetic demand in each zone; and indicators of life cycle analysis (LCA) and environmental impact data from the literature. The results indicate that the small hydro technology is the first alternative on the departments of Amazonas, Caquetá, Chocó, Guaviare, Putumayo and Vaupés, while photovoltaic is the top in Guainía, Meta, Arauca, Casanare and Vichada.
