\"Prod_petrole\"<\/a>Le gisement P\u00e9trolier de lacq fut d\u00e9couvert en 1949, le gisement gazier, ne le f\u00fbt qu’en 1951. Son r\u00f4le f\u00fbt primordiale de 1957 \u00e0 1967, puis il n’a cess\u00e9 de d\u00e9cliner depuis (en part relative d’abord, en part absolue ensuite). La production actuelle de gaz naturelle (lacq profond<\/a>) tient plus au fait de la volont\u00e9 de r\u00e9cup\u00e9rer un site de stockage profond qu’\u00e0 un int\u00e9r\u00eat \u00e9conomique. Economiquement parlant, Lacq profond apparait mort. Au total, la production fran\u00e7aise de m\u00e9thane  est de l’ordre de 3% du total de la consommation.
On utilise plusieurs sortes de gaz en France. Si le gaz naturel est pr\u00e9pond\u00e9rant aujourd’hui, il \u00e9tait minoritaire jusqu’en 1972.<\/p>\n

En effet, plusieurs sortes de gaz sont utilis\u00e9s chez le particulier, ou industriellement :
– le grisou<\/a> (r\u00e9cup\u00e9r\u00e9 \u00e0 l’heure actuelle sur les anciens gisements houillers),
– le gaz manufactur\u00e9 (produit \u00e0 partir des huiles de p\u00e9trole),
– le gaz de cokerie<\/a><\/span> (le gaz d’\u00e9clairage), bien vivace aussi chez le particulier jusqu’aux ann\u00e9es 1960\/ D\u00e9but 1970,
– le gpl,
– le gaz de haut fourneau (qui est r\u00e9utilis\u00e9 dans le processus industriel),
– le gaz de raffinerie. Jusqu’aux ann\u00e9es 1970, ces diff\u00e9rents gaz \u00e9taient pr\u00e9dominent dans le bilan \u00e9nerg\u00e9tique. La consommation s’est \u00e9tablie ainsi :
1973 : 190 TWh, 1983 : 250 TWh, 1993 : 350 TWh, 2003 : 500 TWh. Cet accroissement de consommation s’est pour ainsi dire quasi exclusivement d\u00e9roul\u00e9 dans le tertiaire\/habitation. Ailleurs en Europe, la consommation est encore plus d\u00e9velopp\u00e9 (l’\u00e9lectricit\u00e9 pour le chauffage est moins utilis\u00e9e, voire interdite).
On peut compter une centaine de TWh pour les autres sortes de gaz. Il s’ensuit que si une politique forte d’\u00e9conomie \u00e9nerg\u00e9tique voyait le jour, dans le b\u00e2timent, elle concernerait avant tout la consommation de gaz naturel, ensuite d’\u00e9lectricit\u00e9, enfin seulement de p\u00e9trole.
D’autre part, il \u00e9tait clair que d\u00e9s le d\u00e9but des ann\u00e9es 1960, la production nationale s’av\u00e9rerait vite insuffisante \u00e0 suivre le d\u00e9veloppement qu’on voulait lui donner. les co\u00fbts d’investissements sont consid\u00e9rables, et la production locale compl\u00eat\u00e9e par des importations d’abord n\u00e9erlandaises (82 % en 1973, 16 % aujourd’hui), ensuite alg\u00e9riennes (18 % en 1973, 22 % aujourd’hui) et surtout norv\u00e9giennes (30 %) maintenant, en attendant d’\u00eatre russe (24 % \u00e0 l’heure actuelle).<\/p>\n","protected":false},"excerpt":{"rendered":"
