La production nette d’\u00e9lectricit\u00e9 des Etats Unis en 2007 s’est accrue en un an de 2,3% \u00e0 4160 TWh, nous informe l’Energy Information Administration. C’est sept fois environ la production de la France.\"Usaelectricit2007_3\"<\/a>  Cette croissance est imputable \u00e0 la forte consommation d’\u00e9lectricit\u00e9 dans le r\u00e9sidentiel (+3%) et le commercial (+3,3%) et un tassement dans l’industrie (-0,5%).<\/p>\n

                             Cette croissance de consommation s’inscrit dans la tendance de demande continue des am\u00e9ricains pour plus de confort et d’\u00e9quipements modernes (Fig.). \"Usaelectricit\"<\/a> Outre l’American Way of Life il faut aussi noter qu’un MWh pour un foyer am\u00e9ricain co\u00fbte 10,64$<\/span><\/strong>, il en co\u00fbte 12,1 euros pour un Fran\u00e7ais avec 24% de taxes et 19,5 euros pour un Allemand avec plus de 26% de taxes. Le faible prix au d\u00e9tail de l’\u00e9lectricit\u00e9 aux Etats Unis,<\/u> en raison de l’absence de taxes significatives et de l’utilisation \u00e9conomique et massive du charbon, est un des facteurs de consommation d\u00e9brid\u00e9e de cette forme d’\u00e9nergie.<\/p>\n

               Parmi les sources d’\u00e9nergies utilis\u00e9es, il est \u00e0 noter une forte d\u00e9croissance de la g\u00e9n\u00e9ration hydro\u00e9lectrique (-14%) qui a entra\u00een\u00e9 une d\u00e9croissance de l’\u00e9lectricit\u00e9 produite \u00e0 partir des \u00e9nergies renouvelables de 9% \u00e0 351 TWh<\/u>. L’\u00e9nergie \u00e9olienne ne participe que pour 0,77%<\/span><\/strong> du bilan global malgr\u00e9 une croissance de 20% \u00e0 32 TWh. L’utilisation du gaz naturel conna\u00eet une forte croissance de 10% \u00e0 893 TWh, celle du nucl\u00e9aire progresse de 2,5% \u00e0 806 TWh et celle du charbon de 1,5% \u00e0 2020 TWh.<\/p>\n

              La g\u00e9n\u00e9ration d’\u00e9lectricit\u00e9 aux Etats Unis repose toujours sur l’utilisation massive du charbon pour pr\u00e8s de 49%. La progression de l’utilisation du gaz naturel  s’est faite aux d\u00e9pens de l’utilisation du p\u00e9trole, mais elle devrait encore progresser en raison de la pression \u00e9cologique de certains Etats et des incertitudes sur l’\u00e9ventualit\u00e9 d’une taxe carbone qui p\u00e9naliserait le charbon.<\/p>\n

                La consommation d’\u00e9lectricit\u00e9 aux USA pourrait, dans les dix ans \u00e0 venir, conna\u00eetre les d\u00e9buts d’une vraie r\u00e9volution avec l’arriv\u00e9e des futurs v\u00e9hicules hybrides rechargeables (Plug-in) ou des v\u00e9hicules \u00e9lectriques "de voisinage". Pour l’instant le poste transport ne p\u00e8se que pour 2 milli\u00e8mes des ventes US \u00e0 8 TWh, il pourrait devenir significatif dans le courant de la prochaine d\u00e9cennie qui devrait voir d\u00e9cro\u00eetre la consommation d’essence au profit de l’\u00e9lectricit\u00e9.<\/p>\n
