I walk thru the house and turn off appliances whenever I can.

IT was a major point of contention in my mom's house. She'd run the TV 24/7!
I'd turn off lights and get yelled at. Sad to say that the next bill will be alot lower.

IT really helps to shut down all appliances that you are not using. I have even begun to shut off the monitor and modem when I am not using them.
