Why don't we cover the desert with solar panels? | Dan Kwartler

Stretching over roughly nine million square kilometers and with sands reaching temperatures of up to 80° Celsius, the Sahara Desert receives about 22 million terawatt hours of energy from the Sun every year. That's well over 100 times more energy than humanity consumes annually. So, could covering the desert with solar panels solve our energy problems? Dan Kwartler digs into the possibility. [Directed by Christoph Sarow, AIM Creative Studios, narrated by Jack Cutmore-Scott, music by André Aires].
