Je sais qu’entre la production, la fabrication et la distribution, les pertes sont importantes.

L’énergie grise correspond à la somme de toutes les énergies nécessaires à la production, à la fabrication, à l’utilisation et enfin au recyclage des matériaux ou des produits industriels.

Exploiter les sables bitumineux est la façon la plus sale, la plus chère et la plus énergivore de produire du pétrole. La production d’un baril issu de ces sables nécessite 5 barils d’eau, un demi baril de gaz et émet jusqu’à cinq fois plus d’émissions de gaz à effet de serre que le pétrole conventionnel.

Le véritable problème reste la pollution des sols, de l’eau et de l’air.

En général on se situe sur des valeurs proches de 20%.

Je suis sûre qu’on consomme bien plus d’énergie à aller chercher ce pétrole que celle fournit par le pétrole en question.
Pauvre planete!
