do they make green plugs anymore?

[Christie]

I remember in the late 90s we used a green plug on our refrigerator to save
on energy costs. Do they make the plugs anymore? I can't find them online
anywhere.

I believe they don't sell them because they don't work.

The same can be said for any number of products hawked on infomercials
and then later taken off the market when the companies were sued by
angry consumers when the products don't work as claimed.

I ran across one of those things once in back of a refrigerator. I
was amazed how hot it was, and got to thinking that it had to be
wasting more energy than it could possibly save.

I thought those green plugs were just power factor correctors in a
box, and nowdays, anything reactive has a PFC power supply in it?

Not really. Motors are reactive and don't come with PFC standard.
But most electronics now come equipt with Switch mode power
supply. These are easy to PFC.


PFC dosn't work with refrigerators. They work well with motors
that are running lightly loaded or have a varyable load. A
'fridge or AC has a motor that is closely matched to it's load.
So PFC doesn't do any good.
