Skiing at a waste incineration plant in Copenhagen
Ehrhorn/Hummerston

CopenHill

Copenhagen, Denmark

CopenHill is a clean power plant that creates energy by burning waste instead of fossil fuels. But the facility, which opened in October, has something else that makes it special: It does its part to make sustainable living fun. The roof features a public park and a recreation center that includes the world’s tallest artificial climbing wall, a hiking trail, gardens, and a 1,300-foot artificial ski slope. The slope is designed to provide the sensation of skiing. But it doesn’t rely on cold temperatures or machine-made snow. That means visitors can enjoy year-round, Earth-friendly fun. —Rebecca Katzman
