Pour r\u00e9pondre \u00e0 la question, non d\u00e9nu\u00e9e d’int\u00e9r\u00eat concernant le co\u00fbt de l’\u00e9volution vers une soci\u00e9t\u00e9 moins vorace, il est n\u00e9cessaire de poser un certain nombre de bornes.
La France consomme 280 millions de TEP, toutes \u00e9nergies confondues. Bilan global. En ce qui concerne le logement, l\u00e0 o\u00f9 se situe le probl\u00e8me principal, il est n\u00e9cessaire de cadrer le probl\u00e8me.
J’ai souvent dit qu’un quart du parc de chauffage \u00e9tait bon,
un quart \u00e0 changer,
un quart \u00e0 changer d’urgence,
\"Gaspi_2\"<\/a> Et je vous laisse deviner ce que je pense, et ce qu’est l’\u00e9tat du dernier quart.
Passer \u00e0 du moins vorace, c’est \u00e0 dire r\u00e9duire la consommation, n’est pas synonyme forc\u00e9ment d’\u00e9nergie renouvelable.
Passer de 3500 \u00e0 1500 litres de fioul, c’est un tr\u00e8s grand rendement (m\u00eame si l’on d\u00e9pend encore du fioul).
L’investissement ? Amorti sur trois\/quatre ans.
2 tonnes de fioul jusqu’en 2020, c’est 26 tonnes, environ 160 barils de brut.
Et le bon mat\u00e9riel en question co\u00fbte environ 3000 euros, install\u00e9.<\/p>\n

Dans ce cas de figure, le gain sur 13 ans est au minimum de 6000 euros, sans doute beaucoup plus.
Sans changer d’\u00e9nergie.
Des aigrefins font croire que le renouvelable est responsable de certains gains.
C’est faux. C’est le changement de g\u00e9n\u00e9ration de mat\u00e9riel qui doit \u00eatre mis en relief, des travaux d’entretiens, de r\u00e9novation, etc…
Si l’on pr\u00e9voit des travaux importants sur les habitations, une enveloppe globale de 600 milliards  d’investissements sur les b\u00e2timents \u00e0 l’horizon 2020, soit 50 milliards par an (tous ne seront pas des investissements frais, une fraction aurait \u00e9t\u00e9 de toute fa\u00e7on engag\u00e9, comptons la moiti\u00e9), il faut penser que l’effet de levier<\/a> sera tel avec les \u00e9conomies d’\u00e9nergies, qu’on est plus dans un cas de figure de co\u00fbt, mais d’\u00e9conomies.
Les plus "p\u00e9nalis\u00e9s" \u00e9tant les plus neufs, pour qui le gain serait le moins important.
Pour donner un ordre de grandeur, chaque euro investit entre 2008 (dans une technologie fiable) et 2020 sera rembours\u00e9 en 2020, et aura donn\u00e9 1\/2 euro de rendement.
Encore ceci n’est vrai qu’avec une stagnation du prix de l’\u00e9nergie, avec une augmentation, ce sera bien plus.
On est donc bien dans le cadre d’un investissement  :  une  "d\u00e9pense"  en capital<\/a> qui finit  par rapporter, et qui rapporte GROS.  <\/p>\n","protected":false},"excerpt":{"rendered":"
