QOTD on Smart-Grid Privacy

We, Siemens, have the technology to record it (energy consumption) every minute, second, microsecond, more or less live.
From that we can infer how many people are in the house, what they do, whether they're upstairs, downstairs, do you have a dog, when do you habitually get up, when did you get up this morning, when do you have a shower: masses of private data.
We think the regulator needs to send a strong signal to say that the data belongs to consumers and consumers alone. We believe that's a blocker to people adopting the technology.

-- Martin Pollock of Siemens Energy
