Re: not smart
"They don't know what power I use and at what time, all the now is substation X is drawing Y power at Z time. They also don't know what is using the electricity in my house.
So in answer to your point, they are intruding a lot."
Firstly, how does a smart meter "know what is using the electricity in my house"?
Secondly, how is knowing when you're using the energy an intrusion? That's like saying your ISP and mobile phone provider are intruding because they know exactly how many Kb you are downloading/uploading each second, or that BT are intruding because they itemise exactly when you make each phone call, and how long it lasts.
It's almost like all the privacy-freaks haven't really thought this through before getting all hot and bothered. Seeing a 2min spike in your energy use at 5:17pm is surely far less intrusive than knowing you phoned your mum at 7:13pm for 5 minutes and 4 seconds?
The only thing that's "serious scary" is how uninformed supposedly well-educated, tech-savvy people are, and how little they think before jumping on a bandwagon.
