Copenhagen's new $640 million power plant will have a ski slope on its roof - take a look

Power and waste management plants are usually kept outside major cities so that residents don't have to see the plumes of smoke or smell burning trash.

Copenhagen's new energy plant designed by Bjarke Ingels Group is a little different - it's both sustainable and an incredible piece of architecture. Dubbed the Amager Resource Center (ARC), the building will turn trash into power that will then go to the city's grid. When it goes live later this year, it will generate less CO2 than the city's former plant, too.

The plant's unique design doesn't stop there. It will also feature a nearly 2,000-foot-long ski slope and the world's tallest artificial climbing wall.
