How Much Room Do We Need To Supply The Entire World With Solar Electricity?

22.04.2015 | IFL Science | www.iflscience.com

In 2009, the total global electricity consumption was 20,279,640 GWh. The sun creates more energy than that in one hour. The tricky part is collecting that energy and converting it into useful electricity with solar panels. 

How much area would need to be covered with solar panels in order to capture enough energy to meet global demand? Actually, it’s not as much as you’d think.

The image above has three red boxes showing what area would need to be covered for Germany (De), Europe (EU-25), and the entire world.
