Almeno tre quarti della produzione di energia mondiale dovrà arrivare entro la fine del secolo da fonti rinnovabili.

In caso contrario sarà praticamente impossibile limitare il riscaldamento globale. A dirlo è un articolo pubblicato sulla rivista Science da Atul Jain dell’Università dell’Illinois di Urbana-Champaign. Secondo Jain, bisogna dunque abbandonare in modo massiccio l’uso di combustibili fossili.

Per impedire un aumento della temperatura globale al di sopra dei due gradi entro la fine del secolo, l’unico modo è costruire una centrale a emissioni zero per i prossimi cinquant'anni a partire da oggi.

"Abbiamo bisogno di sviluppare le tecnologie appropriate ora" conclude l’autore della ricerca.
