How can I lower this cost?
Three high-impact moves: (1) shift heavy usage to off-peak hours if your utility offers time-of-use pricing; (2) switch to a more efficient unit (Energy Star); (3) reduce hours of use. For appliances with always-on standby draw, an inexpensive plug-in Kill-A-Watt meter often pays for itself by revealing surprise loads.
