Agreed, the only problem with these devices as I see it is that they themselves consume energy. Also I suspect the output is not so fun / worthwhile. Perhaps it can help people to tweak their refrigerators a couple of degrees but then again, the only real weapon against electricity overuse is pricing.

What we "need" is a carbon tax, I do not like people telling me I cannot use electricity in whatever quantities I feel like. I will however respect the fact that said electricity cant be had for free.
