Et bien il y a tout d’abord le prix de l’essence qui ne cesse de monter, mais l’augmentation de prix ne compense pas \u00e0 elle seule l’augmentation de rendement.<\/p>\n
Ce qui explique que notre consommation ne diminue pas, c’est l’effet rebond<\/b>. L’effet rebond, voici ce qu’en dit Wikipedia :<\/p>\nImaginons une situation o\u00f9 la consommation ne peut augmenter par manque d\u2019argent. Le march\u00e9 est \u00ab\u00a0plafonn\u00e9\u00a0\u00bb par le pouvoir d’achat des consommateurs. Arrive une am\u00e9lioration de l\u2019efficacit\u00e9 des syst\u00e8mes de production r\u00e9duisant les co\u00fbts par unit\u00e9. Cette innovation va d\u00e9gager des \u00e9conomies permettant de consommer plus de produits ou services jusqu\u2019\u00e0 atteindre \u00e0 nouveau les limites financi\u00e8res.\n<\/p><\/blockquote>\n
En gros, cela veut dire que la r\u00e9duction de consommation engendr\u00e9e par la technologie va nous permettre de consommer plus. On aura toujours un budget constant pour la voiture (en faisant abstraction de l’inflation) mais ce budget nous permettra de faire plus de kilom\u00e8tres ! Cet effet est b\u00e9n\u00e9fique pour l’\u00e9conomie car il fait cro\u00eetre la consommation, par contre, il est clairement n\u00e9faste dans une optique de r\u00e9duction de notre consommation !<\/p>\n
Vous l’aurez compris, il s’agit l\u00e0 d’un cercle vicieux qui fait que m\u00eame s’il y a des espoirs technologiques sur les instruments de consommation quotidien, c’est notre mentalit\u00e9 qu’il faut changer et pas la technologie (m\u00eame si celle ci peut clairement aider).<\/p>\n","protected":false},"excerpt":{"rendered":"
