How Much Space for Solar?

This piece of art comes from the Land Art Exhibition and illustrates how little space would be needed to meet the world's energy needs - if it all came from solar. (Click the picture for a better view)

Obviously there are many other renewable energy sources, but the artwork helps show how little area would be required. And a fair bit of that area could be on rooftops - so it doesn't take up any actual land.

Also, this is based on 2030 projections - which is way more energy than we use today.
