Which is used to heat buildings in Reykjavik, Iceland during winter?

Doesn't that look pretty with all the different colours of roofs.

They even grow bananas, in huge plastic tunnels, using this underground heat.

Ginger, it's a really nice country and Society, we visited it twice

Iceland is the most beautiful place I've ever visited

I have learned so much about Iceland from this game.

I spent 2 days there in late December taking advantage of Iceland Air's was astonished at how awesome it is.

Can't edit when accidently hitting ok??!! Geesh. was going to say the airline lets you stay for up to 7 days without extra charge on your way to Europe. Had I known it's so awesome, would have stayed longer.

Davy, Livingston, why? everybody speaks good English.

luckycatfay, Cozzy 25, Yes it does! When I saw your comment, I had a look & they are very pretty. 😎

So smart to use local and natural resources freely available

luckycatfay, in my grandparent's town, roofs are all brown. the color of rusted tin roof😁
