iktv, thats a nice savings. Good job!
Most of us could do a lot to cut our power usage if we really want to. Run huge loads of wash and dryer, and using cold water helps.
"Energy vampires" are all those little lights that are lit on appliances, tv's, stereos, and almost any appliance in the home even when not being used. I unplug those until needed.
Keep the heat down {if elec is a large part of it} Close off rooms that dont need heat, but dont let any pipes freeze in winter.
Use your lites as heat for the house as much as possible, Even running them at nite if needed. Good luck
