They are being advertised on TV as saving electricity. Now we all know

That's what I understand. TPTB expect you to look at the meter every
few minutes and run around switching off lights, phone chargers etc to
save a few watts. My impression is that most people pretty soon get
bored by them and stop looking, presumably reverting to their former
wasteful or otherwise behaviour.


In the good old days of electro-mechanical meters there was a nice big
wheel which you could monitor go around. You could see or measure
what happened when you put the kettle on, or as one did in those days,
switched on the electric heater. Which was all fine and dandy but it
didn't give alternatives to boiling the water or from being cold so
even in those days no money was actually saved.

Modern meters have a flashing LED. Flashes once per watthour.
