I can't stop thinking about fridges and winter. Would it save much energy to freeze gallon containers of water outdoors and put those in the fridge now and then? It's Minnesota winter over here and I want to make the most of it ;)

Since December 2006, my electricity bill has shown at least a 1,000 KWH increase over the same period a year ago. We haven't purchased any new appliances, or done anything appreciably different. This month, we didn't use our air conditioning/heating unit at all, and our bill still came in 25% higher (500 KWH) than a year ago. We're at a loss. What could be the reason? We ordered a Kill-a-watt, but till it arrives, we are trying to figure it out. Any thoughts? [more inside]
