Simplest Energy Loss Correction

I purchased several packages of these foam insulators and started working my way through the house removing electrical plate covers and putting these foam insulators behind the plate, then screwing the plate back on.

The final correction is to plug all unused sockets with these simple plastic toddler outlet protectors. This is a job I can do a little at a time. Even when I'm on the phone, I can walk around with my screwdriver and package and work on outlets.

Quick. Easy. Cheap. So simple and it yet it adds up to big savings in energy and gives me a positive action in lowering my carbon footprint.
