I learned the hard way what's happening with smart meters in Europe. The same type of smart meter they're using here in France has already been deployed in many EU countries.

Mostly, we hear only about the negative health effects of wireless smart meters, but the ones here only send data back over the power lines.

In short, with a smart meter, you may end up with less juice to power stuff, and more frequent main breaker trips as people exceed their (now reduced) capacity.
