Le Professeur Marc Fr\u00e8re a abord\u00e9 la probl\u00e9matique de l’\u00e9nergie de mani\u00e8re factuelle et historique dans une conf\u00e9rence intitul\u00e9e \u00ab\u00a0Energie : Menaces et opportunit\u00e9s d’une probl\u00e9matique sous-estim\u00e9e\u00a0\u00bb et qui s’est tenue ce mardi 12\/04 dans les b\u00e2timents de l’Universit\u00e9 de Mons \u00e0 Charleroi.<\/span><\/p>\n

Quels liens ont \u00e9t\u00e9 tiss\u00e9s entre l’homme et l’\u00e9nergie au cours de l’histoire ? Quel est le probl\u00e8me\u00a0 aujourd’hui ? Que souhaiter pour le futur ? Quel est notre niveau de d\u00e9pendance \u00e9nerg\u00e9tique ? Quel r\u00f4le jouent les technologies dans notre mod\u00e8le de consommation ?\u00a0Dans un expos\u00e9 illustr\u00e9, Marc Fr\u00e8re, Professeur\u00a0de Thermodynamique \u00e0 la Facult\u00e9 Polytechnique\u00a0a emmen\u00e9 son public dans une balade historique et futuriste,\u00a0en voici un bref r\u00e9sum\u00e9.\u00a0<\/span><\/p>\n

Le mode de consommation d\u2019\u00e9nergie des soci\u00e9t\u00e9s d\u00e9velopp\u00e9es est probl\u00e9matique \u00e0 plus d\u2019un titre. Conflits g\u00e9opolitiques, r\u00e9chauffement climatique et impact environnemental de l\u2019exploitation des ressources sont des menaces \u00e0 court, moyen et long termes pour notre soci\u00e9t\u00e9. Celles-ci r\u00e9sultent principalement des choix r\u00e9alis\u00e9s par le pass\u00e9 en termes de sources d\u2019\u00e9nergie (majoritairement fossiles) et de technologies de conversion de ces sources en \u00e9nergie utilisable.<\/p>\n

Pr\u00e9sent\u00e9e de cette mani\u00e8re la probl\u00e9matique \u00e9nerg\u00e9tique semble donc essentiellement technologique et toute r\u00e9ponse aux probl\u00e8mes que pose ce mod\u00e8le ne peut donc \u00eatre que technologique. Pourtant, ce mod\u00e8le \u00e9nerg\u00e9tique ax\u00e9 sur les \u00e9nergies fossiles est le r\u00e9sultat d\u2019un long processus o\u00f9 les aspects \u00e9conomiques et sociologiques n\u2019ont rien d\u2019anecdotique. Changer ce mod\u00e8le est donc l\u2019affaire de tous et non une t\u00e2che \u00e0 laisser aux seuls technologues.<\/p>\n

Apr\u00e8s une br\u00e8ve description du mod\u00e8le \u00e9nerg\u00e9tique actuel au niveau plan\u00e9taire, Marc Fr\u00e8re, aussi Pr\u00e9sident de l’Institut de Recherche en Energie de l’UMONS a explor\u00e9 ses origines et ses liens avec notre mod\u00e8le de soci\u00e9t\u00e9 occidentale. Une \u00e9tude prospective jusque 2100 a permis ensuite de d\u00e9finir les objectifs \u00e0 moyen et long termes de la transition \u00e9nerg\u00e9tique. Pour illustrer ce qui est technologiquement faisable dans un secteur donn\u00e9, un focus sur la consommation \u00e9nerg\u00e9tique des b\u00e2timents a \u00e9t\u00e9 pr\u00e9sent\u00e9. Il a permis de mettre en lumi\u00e8re l\u2019\u00e9norme potentiel d\u2019\u00e9conomies d\u2019\u00e9nergie dans ce secteur et les innovations technologiques qui ont vu le jour ces derni\u00e8res d\u00e9cennies.<\/p>\n

Quelles sont les limites actuelles de la technologie qui emp\u00eachent d\u2019atteindre l\u2019objectif de b\u00e2timents totalement autarciques utilisant les \u00e9nergies renouvelables ? Ces limites sont-elles amen\u00e9es \u00e0 tomber ou est-ce notre mode de vie qui devra \u00e9voluer ? Telles sont les questions qui ont \u00e9t\u00e9 abord\u00e9es en fin d\u2019expos\u00e9 au travers de la description de quelques projets de recherche ou de d\u00e9monstration r\u00e9cents ou en cours.<\/p>\n
