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]
