Après, on peut toujours discuter des chiffres mais ça donne le tournis. On a à peu près tous assisté au début de la téléphonie mobile et quand on lit maintenant que 61% de la population mondiale utilise un GSM… C’est complètement dingue la vitesse à laquelle ça s’est développé, imposé puis devenu un élément dont on aurait bien du mal à se passer! Le monde est vraiment fou! ^^

En charchant la source des informations donnees, je suis tombe sur le lien suivant:

http://fatknowledge.blogspot.com/2007/01/carbon-footprint-of-mobile-phone.html

En lisant (en diagonale) le rapport auquel il se refere, je n’ai pas trouve les chffres tels quels, et j’ignore la methode de calcul de l’auteur. Mais si on estime que 50% de ces 4221 MJ sont dus au GSM en lui meme, et que 1390 MJ sont dus a sa fabrication, il reste environ 720 MJ de consommation, ce qui equivaut a 22W de facon continue pendant un an. Or un chargeur consomme moins de 10W en charge… Je doute donc de la pertinence de ces chiffres.

4 221 Megajoules, ca represente une consommation continue de 134W pendant 1 an. Un chargeur Nokia consomme a peu pres 6W en charge , et au maximum la moitie s’il reste branche sans etre utilise (ce qui est un vrai gaspillage c’est sur). On est donc loin des chiffres annonces. Reste a voir si ces chiffres tiennent compte du cout energetique de production, et d’alimentation des reseaux de telecoms…
