Hugh, we're southern coop also. Recent contract with the generating company expired and everybody's bill went up. Last month we used almost $50 worth of electricity, plus the high cost ($50) of having a meter.
Probably one large difference is that I built a house that needs no air conditioning. Everybody in a humid climate needs to dehumidify, you (and all my neighbors) use ac for that. I use a cheap used dehumidifier, which costs $30/mo to run.
Obviously house size varies a lot. We have 20,000 cu ft of house. Same as a 2500 sq ft house with 8' ceilings.
Our annual electric bill for our total electric house and well pump isn't half yours unless I do a great deal of welding.
One way you could improve is to add a heat pump water heater if your electric tank heater is in a convenient location. We use ours seasonally, heats water 2-3 times more efficiently than electric resistance. Beyond that, a major benefit is the free by-product: cool dry air. Sound like your ac? Ours provides half our needed dehumidification. More, if we used more hot water.
Return on investment (ROI) was less than 2 season's use. Unfortunately, I'm about to replace ours after 13 year's use. Fortunately, I have a spare that I picked up cheap awhile back. I haven't priced a new one lately, but ROI should be less than 5 seasons.
A general rule is that most spend one month's income on space heating/cooling. Higher income = larger house = larger bills. Didn't make much sense to me, so I built a place that costs me closer to one day's income.
A nearby friend cuts 4 1/2 cords of hardwood here for his winter use in a house same size as mine. I keep telling him to sell that dog to someone else and go build a better house. If I don't feel like lighting the stove, I put on a sweater evenings. We go through maybe 2/3 cord because we enjoy the stove. The house generally runs 65º winters, without me doing anything.
