Análise da eficiência na produção de energia eólica nos principais estados brasileiros produtores, por meio da aplicação de análise por envoltória de dados

Abstract

Wind energy is energy produced by the force of the winds, and it is considered clean and renewable. There are many factors that can be used to analyze the efficiency in the production of electricity from wind, in the main Brazilian states. The main objective of this research paper is to assess the relative efficiency of wind generation in the main producing Brazilian states in 2014, by applying data envelopment analysis (DEA). Four out of eleven units assessed were considered efficient and seven non efficient. Then the inverted frontier model was used to order the units according to the measurement of an efficiency index, as defined by normalized efficiency. Furthermore, the inverted frontier method identified two efficient units as having a false efficiency. Thus, wind energy production of the state of Piauí was presented as the most efficient unit of the whole analyzed, in contrast to the state of Pernambuco’s, which was considered the least efficient of all.
