I have one here in Bucharest and, while fancy, as in it blips a red light when the power consumptions is higher than usual, it doesn't help me at all.

As in, yeah, running the washing machine is power consuming, I knew that, and the same goes for the electric oven or for the vacuum cleaner, but what am I supposed to do with that information? Not wash my clothes anymore? Not using the oven? Leaving dust all over the place for longer?
