« Nous sommes convaincus que notre démarche est nécessaire pour parvenir à un monde meilleur. Nous devons collectivement changer les modes de production d’énergie sur la planète. D’autant que les énergies renouvelables sont devenues compétitives.
Ainsi, nous offrons à nos partenaires la possibilité de changer de modèle économique et de basculer sur le modèle du futur, alternatif aux énergies fossiles et peut-être au nucléaire. »
