14.000 EOLIENNES ABANDONNEES AUX USA Aux USA, il a fallu dix ans pour se rendre compte que les éoliennes n’étaient pas rentables pour des raisons évidentes : énergie intermittente donc rendements totalement insuffisants, coûts de maintenance et coûts de fonctionnement extrêmement élevés…… car pour que les mécanismes des éoliennes ne se dégradent pas, il faut qu’elles tournent. Le comble, c’est de devoir les faire tourner quand il n’y a pas de vent ! Mais un autre dilemme s’est présenté, il a fallu arrêter les éoliennes quatre mois par an, car elles décimaient des milliers d’oiseaux migratoires et entre 600.000 et 1000.000 de chauve-souris sur une année.
