2. Coober Pedy, Australia
In a place where temperatures regularly soar into the 90s and the 100s in the summer, it’s understandable that the residents of Coober Pedy, Australia would do anything they can to beat the heat. And, here, it’s all about living underground. Often referred to as the ”opal capital of the world,” more than half of this mining town’s residents live in homes in dug out caves on the hillsides, where temperatures are steady and a cool relief from the scorching heat outside. Building a “dugout” costs about the same as building a home on the surface, with the added bonus of not having to worry about all those high energy bills from air conditioning. Also underground? Shops, churches, and even a four star hotel!
