(p. A16) Copenhagen has splashed out on every kind of green widget to shore up its environmental credentials as host of the world’s biggest climate change conference in years. Most of the emissions-free wizardry is familiar, such as electric cars. Here’s one you may not have seen yet: An extra “green” Christmas tree.

At the Danish capital’s City Hall Square, 15 to 20 volunteers can sit on stationary bikes located around a massive, decorated tree and pedal away to keep it light, at least during the day. The bikes are connected to electrical tie-ups that ultimately power hundreds of lights on the tree.
. . .
Late at night, the big tree continues to sparkle–but thanks to traditional power outlets, not pedal power–once the volunteers have gone home.
