Wow that is pretty weird...... anybody has a reasonable explenation to this darkness in north korea?
Yes, the poor economy of the North. It is a country which can not feed itself, is suffering starvation and simply does not have the resources that the South has. As a result there is far less street lighting and illuminated buildings.
Edited to add:
for another example of this look at South Africa. By African standards this is a rich and developed nation. It is fairly well illuminated when you compare it to it's neighbours.
