Just wait untill electric companies rais rates th where it is more than gasoline. The electric company that i have gouges the hell out of there customers. I do not have a large house and a newer a/c unit. Im $480 during summer and right now in winter im $290. They have been raising rates last few years. Another company in the area i have friends paying during summer $300 during the hotter months and have older homes with older a/c units. Go all electric then rates will go higher since you have no choice.
