What's the big deal with privacy?
I don't get it. What do I care if the power company knows how much energy I use at different times of the day? I have nothing to hide.
Personally, I would love to lower my energy bill by 20%, even if the power company knows that I turn up the thermostat when the temperature is lower outside. It would also be great if the power company could say "Hey, we noticed your refrigerator is using twice as much power as it was a year ago. Maybe you should think about repairing or replacing it."
zackers, we have smart meters now here. No fiber. The signals are sent right back over the power lines.
