There's no doubt that they do decrease consumption. It's sometimes in the order of 30% or 35%. People don't like them because they add an element of uncertainty to the bill. In many cases, people don't realize that in an average apartment building when you go to submetering, or some landlords have the metres for electricity installed so they can measure what electricity is going to what unit, you find that about 15% of the users use a great deal; about 15% are on average; and 70% are using less than the average, so they would save. There's always this concern that “Oh, no, it won't be me who gets the savings.”
One of our provincial groups put out this great cartoon. It had a young person—I'm afraid I took a dig at teenagers before and now I'm going at young people, but if you keep me long enough I'll get to the seniors. The young person is sitting there with his big high-def TV and his three computers running, and all this blah, blah, blah, with power cords like you wouldn't believe. Beneath that picture is a senior citizen sitting there, freezing, and paying the same for electricity. It's stupid. Let the person using all the power pay for it.
