The only times I've noticed power plants are when they blow an obnoxious amount of smoke in the air. If I lived in Copenhagen though, I think I would hang out at their power plant. The waste-to-energy plant is called the Big Vortex and the roof of the plant will be used as a ski slope.
Seriously, it's part of a permanent art installation by realities united. They've also rigged the plant to blow stylish O's in the air instead of the aforementioned obnoxious smoke. [realities.united via Neatorama]
