Too funny :
Saving Energy
You can't send your electricity back. If you could, the counter counts only in one way.
I have been told that you are paying the kWh, not the kVAh, where kWh = kVAh x cos(phi).
All systems with motors, transformers... have cos(phi) != 1.
My kill-a-watt shows the cos(phi).
iirc my computer has a cos(phi) of 0.8-0.9.
I remember on a notebook with LCD off the cos(phi) was going down a lot (0.5 iirc) and then the VA was higher than when LCD was on. On the same time the kWh was lower when the LCD was off than when it was on.
I don't think this thing is something else than a placebo, but I'm OK if someone shows me I'm wrong.
Denis.
