Energy efficiency ratio in the combustion of briquettes in wood ovens
ENSUS2023 - XI Encontro de Sustentabilidade em Projeto, 2023Briquettes are ecological firewood, derived from the drying and pressing under pressure and high temperature of sawdust and wood dust. In recent decades, the search for sustainability and the green economy has increased significantly. As a result, several studies and scientific projects have been designed to increase energy production from renewable

The energy efficiency of oil sands extraction: Energy return ratios from 1970 to 2010
Energy, 2013Abstract It has been argued that the oil sands industry is not energy efficient: comparatively large energy inputs are required per unit of energy output from oil sands operations. Unfortunately, quantitative work to date in this area has suffered from poor data availability and uncertain methods. We apply a new methodology and new dataset to compute
