Transition énergétique, révolution numérique, mutation écologique... Politiques, médias, industriels nous promettent en chœur un nouveau monde enfin affranchi du pétrole, des pollutions, des pénuries et des tensions militaires. Cet ouvrage, fruit de six années d'enquête dans une douzaine de pays, nous montre qu'il n'en est rien ! En nous émancipant des énergies fossiles, nous sombrons en réalité dans une nouvelle dépendance : celle aux métaux rares. Graphite, indium, tungstène, terres rares.

Rare Earth Frontiers is a work of human geography that serves to demystify the powerful elements that make possible the miniaturization of electronics, green energy and medical technologies, and essential telecommunications and defense systems. Julie Michelle Klinger draws attention to the fact that the rare earths we rely on most are as common as copper or lead, and this means the implications of their extraction are global. Klinger excavates the rich historical origins and ongoing ramifications of the quest to mine rare earths in ever more impossible places.
