> It states "The current global solar potential technically available was estimated at about 613 PWh/y." That's 70 terawatts. So there is technically enough potential from solar alone, but it would be a tight squeeze. The study seems to be using very modest assumptions about how much area can be fitted with solar cells (0% in urban areas??), so I think the conclusion should be that there is enough technical potential from solar alone, and it is not a particularly tight squeeze.
