Le p\u00e9trole se fait plus rare et les compagnies p\u00e9troli\u00e8res sont \u00e0 la recherche effr\u00e9n\u00e9es d’alternatives \u00e9nerg\u00e9tiques.<\/p>\n

Bien s\u00fbr il y a les \u00e9nergies renouvelables mais les investissements sont cons\u00e9quents et certains rendements al\u00e9atoires puisque d\u00e9pendant pour certains du vent, pour d’autres du soleil.<\/p>\n

Il existe pourtant une autre source d’\u00e9nergie dont nous avions vaguement parl\u00e9 sur le site (ici<\/a> et l\u00e0<\/a>) il s’agit des sables bitumineux.<\/p>\n

On estime la part exploitable \u00e0 41 milliards de tonne \u00e9quivalent p\u00e9trole (tep) soit environ 40 ans d’autonomie si on remplace notre consommation de p\u00e9trole par les sables bitumineux.<\/p>\n

Alors serait ce une nouvelle \u00e8re ?<\/p>\n

Tout d’abord qu’est ce que ce brol bitumineux ? <\/p>\n

\"\"<\/p>\n

Ces sables bitumineux sont principalement situ\u00e9s sous une for\u00eat bor\u00e9ale au Canada \u00e0 une profondeur de plus de 50m.<\/p>\n

Donc pour commencer l’exploitation il faudra d’abord raser la for\u00eat …<\/p>\n

\"\"<\/p>\n

Ensuite pour exploiter le p\u00e9trole contenu dans ces sables il faut utiliser de l’eau chaude selon le proc\u00e9d\u00e9 de Karl Clark<\/a> ; on estime que pour produire 1l de bitume il faut 4 \u00e0 5 l d’eau.<\/p>\n

\"\"<\/p>\n

Sachant qu’il faut traiter 4 tonnes de sable pour produire un barril de p\u00e9trole je vous laisse imaginer le volume d’eau n\u00e9cessaire \u00e0 l’extraction…<\/p>\n

\"\"<\/p>\n

Soyons positif … si si … on va essayer tout du moins financi\u00e8rement parlant!<\/p>\n

Le gouvernement canadien va investir 25 milliards de $ d’ici 2020 pour exploiter cette ressource ce qui devrait cr\u00e9er 44 000 emplois et g\u00e9n\u00e9rer un profit de plus de 100 milliards de $.<\/p>\n

Maintenant il reste \u00e0 savoir qui va r\u00e9ellement profiter de ces milliards ?<\/p>\n

Je parierais bien ma culotte que ce ne seront pas les indig\u00e8nes, pari tenu ??<\/p>\n

Soyons un peu lucide maintenant…<\/p>\n

La production d’un barril de p\u00e9trole issus de ces sables est tr\u00e8s gourmande en \u00e9nergie, on estime que pour produire un seul baril de p\u00e9trole provenant des sables bitumineux il faut br\u00fbler l’\u00e9quivalent de un tiers \u00e0 deux tiers de baril de p\u00e9trole.<\/p>\n

Ajoutons y un impact environnemental des plus catastrophiques et vous obtenez le magnifique cocktail de l’\u00e9nergie que vous l\u00e8guerez \u00e0 vos enfants.<\/p>\n

Alors au lieu d’investir des milliards dans un puits ne devrait on pas plut\u00f4t investir dans la recherche d’une alternative durable ?<\/p>\n
