Eficiência energética da cana-de-açúcar no município de Teotônio Vilela – AL

Abstract

The energy has been treated as a future demographic, Echonomic and enviromental ́s Problem. The energy balance is an statiscal activity whose purpose is accounting the energy ́s inputs and outputs and thus transform the results into energtic units. So, it becomes na apropriate method to check the energy use in production process. And therefore, it becomes the way how the sistem ́s sustainability is obtained. At that, this paper, looked for a way to analyze the sugar cane ́s efficiency, whose purpose was to estimate the energetic ́s efficiency into an Agroindustrial ́s system in Teotonio Vilea City AL. In the present study were considered the inputs (expenditure) and the power outlets (production), Calculations were made using the transformation of the cost of each agronomic operation for joule (J) and its multiple obtaining the energy expenditure for each activity. The obtained data were obtained from Reunida Seresta ́s Factory, located in Teotonio Vilela AL, from January 2012 to December 2012. The energetic efficiency was positive, the Agricultural Operations like Inputs accounted for 34% of energy expenditure. These one have been considered as the responsible for the biggest Energy expenditure. The act of planting suggar cane, is practible, the energetic balance behaves as an important tool in an agricultural system likewise, because it involves gains with energy, if the system is efficient
