Using an entire box of disposable razors when shaving, discarding each one after a single stroke. Wrapping a small sandwich in yards of tin foil. Keeping every tap in the house running at all times. Taking a bite of an apple, tossing what's left on the ground and moving on to another one. Those scenarios are portrayed as "ridiculous" examples of wasteful behavior in this BC Hydro Powersmart PSA from DDB Vancouver. It closes with a shot of a blazing light fixture in a house where the owners have gone out. The voiceover says: "The most ridiculous thing about wasting power is that for some reason, we don't think it's ridiculous." Actually, I don't think it's ridiculous. I like leaving all the lights on. That way, when I come home, I can clearly see the fruit and razors I've scattered all over the floor and not trip and break my neck.
