i did simple stuff like changed all the regular bulbs to cfls (you cant imagine the wattage difference we have since),turn the computer, printers, speakers, etc, off when done, set sleep timers on the tv so its not watching me when im suppose to be watching it..after im sleep its on for nothing right?, stop running the a/c/heat(turned down) if were not home, etc. Just shut off stuff you arent using (sorry had to say it..LOL) at least enough to offset you added wattage with lights:jointsmile::thumbsup:, you'll see a difference.
