At the same time, the introduction of these energy sources has a positive impact on the national energy security because it reduces the dependence on fossil fuels. This paper examines the effectiveness of the main public policies that introduce NRES in three countries of Latin America: Argentina, Brazil and Uruguay, since 1970 to 2016. The results show that in this period Argentina has had a low performance in these policies in comparison to Brazil and Uruguay, due to regulatory and economic barriers regardless of the economic instruments implemented.enEnergy ResourcesAlternative EnergySustainable DevelopmentEnergy PlanningDeveloping CountriesRecursos EnergéticosEnergías AlternativasDesarrollo SustentablePlanificación EnergéticaPaíses en DesarrolloArtículo Científico Publicado
