Resumen
Así como cualquier otro productobio-energético, la producción de etanol requiere insumos fósiles; enconsecuencia los supuestos beneficios de seguridad energética y mitigación decarbono dependen de en qué medida estos insumos son capaces de generar unimportante rendimiento bio-energético. El etanol brasilero, hecho de cañaazucarera, ha sido reportado como el sustituto más eficiente de la gasolinadentro de las tecnologías que están comercialmente disponibles. Es por esto queha sido objeto de varios análisis de energética,es decir, balances energéticos. Resulta curioso que dichos estudios varíanampliamente dependiendo de la aproximación usada por los estudiosos del tema yadicionalmente no son comparables entre sí, debido a divergencias en el métodode medición. El objetivo de este artículo es la estandarización de losresultados obtenidos por cuatro de los más prominentes autores en este campo,generando de esta manera la posibilidad de contrastar sus estudios y dar algunasluces sobre los estudios de energética aplicados a la bioenergía.Referencias
