Smart Meters DO NOT show daily usage
By and large, in order to figure out current draw and daily usage, consumers must visit a web site, which no one bothers to do.
A real meter - which I have - like the TED5000 shows a $/hr reading all the time on a display we keep by the kitchen table. The kids and I pick up on that info, and have lowered electricity usage by about 20%. Even I, a 'cheap dad' hardly ever visit the web site.
That's the real thing the electrical companies fear - that usage DROPS because that will cause a drop in profits. So they hide behind clumsy web interfaces. A law that puts these readouts in every new or newly renovated house would save at least 10% of electricity usage. (more in places like North America where waste is much worse). Don't expect the green - industrial - complex to allow them, though.
