Previsão e impactos setoriais do consumo de energia elétrica no Brasil: uma análise integrada econométrica com insumoproduto para o período de 2009 a 2014

Abstract

This study proposes a new approach for studying the Brazilian electricity sector, based on the integration of econometric (EC) and input-output (IO) models. Such integration is undertaken through the macroeconomics aggregated. The first step estimates three macroeconomics aggregated (household consumption, exports, and imports), each one disaggregated by 12 economic sectors. The second step uses such estimates to examine the effects of varying the macroeconomics aggregated upon the IO Structure. This allows to obtain sectorial estimates of the macroeconomics aggregated on an yearly basis from 2009 to 2014 and under three different scenarios. Thus, it made possible to identify exports as macroeconomics aggregated that pressure most the sectors regarding the electricity consumption. On other hand, it proved that imports are “not consumer” of the Brazilian electricity sector. The study also presents a comprehensive discussion on the Brazilian electricity sector, as well as the electricity consumption among the sectors analyzed in this study.
