Ein kosteneffizienter Klimaschutz erfordert die Installation von insgesamt 20-80 TWp Photovoltaikleistung bis 2050 und 80-170 TWp bis 2100, also mindestens hundertmal mehr als die bis Ende 2020 installierten 707 GWp. Ein Forscherteam des Fraunhofer-Instituts für Solare Energiesysteme ISE und des Potsdam-Instituts für Klimafolgenforschung hat nun untersucht, ob ein solches Wachstum aus Ressourcensicht machbar ist - und wenn ja, unter welchen Bedingungen. In dem Paper »Technological learning for resource efficient terawatt scale photovoltaics«, (veröffentlicht im September 2021 in Energy & Environmental Science), kommen sie zu dem Ergebnis, dass das derzeit hohe Innovationstempo beibehalten werden muss, um Ressourcenengpässe zu vermeiden.
