Laughs in German! Seriously though. Maybe, if we solve the large capacity storage issues and are able to build a storage system to scale. So 3 or 4 decades if

Laughs in German! Seriously though. Maybe, if we solve the large capacity storage issues and are able to build a storage system to scale. So 3 or 4 decades if we are extremely lucky. But right now in reality.... And it's still not clear if it would be enough in the end. We'd need cover everything in panels and put towers everywhere. The amount of resources needed for solar and wind is actually realistically insane at the scales needed. (one of the many problems usually ignored by wind/solar evangelism)
