Il aborde les problèmes d'une manière concrète, en fonction des occasions et des besoins locaux. los angeles answer specified n'existe pas. Les énergies sont complémentaires, au sein de ce qu'il est convenu d'appeler un bouquet énergétique : l. a. scène est mondiale, mais chaque région a son propre bouquet. L'auteur s'adresse à un huge public cultivé et apporte des informations sur les différentes énergies, leur position dans les sociétés modernes et les problèmes qu'elles posent pour l'avenir.
Il pique l. a. curiosité du lecteur et l'incite à résister aux discours simplificateurs et à l. a. pression des médias. Le citoyen apprendra ainsi à identifier les lobbies qui oeuvrent dans l'ombre et à ne pas céder à des peurs irrationnelles. L'enjeu est de taille : notre avenir énergétique en dépend !
