World Wildlife Fund

The World Wildlife Fund placed these light switch plates in hotel rooms in order to encourage energy conservation. This is a pretty good use of an ordinary light switch plate, so hopefully it caused some people to conserve electricity in the hotel. Previously the WWF has attached a large balloon to the exhaust pipe of a car to demonstrate how much pollution is caused by a day of driving, and turned a towel dispenser in a restroom into the shape of a continent so that you could visualize how many trees were wasted by using paper towels. Overall, the WWF has produced some great guerrilla promotions that have creatively garnered attention-- and hopefully have been successful at changing peoples' behaviors.
