Una rete globale per rifornire il mondo di corrente prodotta in regioni discoste e da fonti rinnovabili, come il solare e l'eolico, è tecnicamente fattibile secondo quanto emerge da uno studio condotto al politecnico di Zurigo.
I ricercatori dell'ETH ritengono che i costi finali per il trasporto di energia pulita dai luoghi dove è più conveniente produrla non supererebbero quelli dell'energia convenzionale.
Gli investimenti necessari per realizzare il progetto, evidenzia lo studio, sono infatti analoghi a quelli che stanno per essere stanziati per il rinnovo delle reti elettriche in Europa.
