Think about the "vampire electronics" in your kitchen -- all of those blenders, coffee pots, toasters and toaster ovens that are sucking down power simply because they're plugged into an outlet. These electronics gobble an estimated 5% to 10% of all the electricity used in U.S. homes, according to the Lawrence Berkeley National Laboratory.
This sounds like a pretty solid idea. Simply unplugging some appliances in the house if they are "vampire electronics" could save a great deal of money in electric bills. I really don't see a downside to something like this other than that the product is faulty or defective. I mean sure the electric companies might lose some profit here and there, but economically overall it can do nothing but good. People will save some money and will be able to use those savings to go buy stuff. Which in turn just keeps the ball rolling in the market.
