OP, could you post a more detailed breakdown so we know if you are paying more in winter vs summer? Also how much of that bill is facility charge? What are your typical thermostat settings? Do you have a well and septic system? These have pumps that use electricity but you make up for it by not paying for water and sewer. You can lower your bill a little if you stop using the clothes dryer and the plasma screen, but I think the only way to get it into reasonable territory is to put in another type of heat, which will cost $$$$ but might pay for itself depending on the cost of the system and type of alternative fuel. It is also worth checking out the math on solar.
I am on a rural coop as well and my facility charge is about $35, then it is 0.11/kWh after that. My bill averages about $200/month and that is with propane for heat (blower uses electricity) and no AC or clothes dryer use at all. I have also done all the easy things like switching to LED bulbs and turning down the water heater temp. The water heater is electric and I am thinking about switching to propane when it dies, but propane prices can swing wildly so I'm not sure if the savings would last. I have looked into solar but it would be something like 30 years to make my money back on it.
I may be wrong but it looks like we have a split ac/heat pump system.
June - 1946 kwh (actual reading)
June - 1763 kwh (prorated reading?)
May - 1193 kwh (actual reading)
April - 5887 kwh (estimated reading)
March - 5887 kwh (estimated reading)
February - 630 kwh (estimated reading)
January - 5888 kwh (estimated reading)
December - 10998 (actual reading, this is where the heater went out so emergency heat via the heat pump had to be used)
November - 2665 (estimated reading)
October - 2663 (actual reading)
I don't think the thermostat works very well as it is set at 70 in the summer and 78 in the winter and while the hallway (where the thermostat is) is appropriately cold/warm, the living room and bedrooms are usually far from that temperature and thus we also have electric baseboards on in the winter.
