I previously posted about re-wiring my doorbell so it would use electricity only when the button was pressed. I also went through my house and placed everything I could find which was "always on" on a switch or power strip.
I replaced power strips which had lights on them with power strips which have no light. I wired switches to all GFCI outlets so I can turn them off when not in use. I have a rooftop TV antenna amplifier which was "always on" and I wired a switch to that.
I placed my entertainment center things on 4 individual power strips (no lights) so I could turn on only what I was using. (Like just TV and DVD, or playstation, or satellite TV - don't need to have on components which are not being used.)
I placed several power strips on my computer stuff. So just computer on - printer on separate power strip and off when not in use. Everything totally off when not in use.
Placed outlet switches on HEPA air cleaners (have always on timers for filter replacement).
Placed power strips (no power on light) on bedroom, garage small stereos. Etc.
Anyway my electric bill is now $2.50 per month less and will be so for the rest of my life. That's $30 a year or being as my electric bill is now under $30 a month - one month of free electricity!
