I know for our part we took the Kilowatt Crackdown pretty seriously. The biggest thing we did was empty and unplug the second fridge/freezer in our basement (which has not been plugged back in since). Beyond that, it was all the standard stuff: swapping in CFL bulbs where we hadn’t already, keeping AC/heat off (mild temps this fall made it pretty easy to keep from turning on heat until end of Oct./early Nov.), sealing up cracks around doors and windows, etc.
