L'azienda elettrica del canton Zurigo EKZ rilancia il progetto di installare pannelli solari sui ripari antivalanghe posti sullo Chüenihorn, sopra il comune grigionese di Luzein, in Prettigovia.
Un primo progetto analogo era naufragato due anni fa. Un comunicato di EKZ indica lunedì che la futura centrale solare alpina potrebbe fornire annualmente tre gigawatt di elettricità, che corrispondono al fabbisogno medio di 660 economie domestiche di quattro persone.
Il luogo individuato, secondo l'azienda elettrica zurighese, offre numerosi vantaggi: sarebbe in particolare possibile produrre elettricità e nel contempo garantire che le strutture esistenti continuino a svolgere la loro funzione di protezione.
