Help. I'm in the panhandle of Florida. It's been in the 80's, pushing close to 90 today. My electricity bill last month was $223. The bill came in today and it's $313. I have an inground pool that has to run about 8 hours per day. New AC system put in last year. The house is 1,556 square feet, about 14 years old. Thermostat is now at 75. If I go any higher, it's like being outside and at times gets extremely muggy. I've noticed that several of my windows (original from when the house was built -- double pane) are foggy. Could this be my problem? Lights are always off, except for the room I'm in. I don't know what to do! Any suggestions? Do I need more insultation in attic? Living room is cathedral. Any input would be appreciated. Thanks!

It sounds like you need a complete study of your house and its energy consumption, which would include insulation values. It is possible that your air-conditioning system was not properly sized...too much capacity is as bad as or worse than not enough, because the system will not dehumidify if it's too big for your home. All we can do is guess, because we have no information. Perhaps your power company will either do an energy study for you, or can recommend someone who does.

I assume your AC has the highest Seer rating you could get. The higher the seer the lower the operating cost.
The fogging of the windows indicate that the seal between the glass panes was lost. The glass has drawn in moisture between the panes. When the house is cool moisture develops on the inside glass pane. Changing the glass will do very little to improve your operating cost.
Have you had your attic insulation checked? What about attic ventilation? You need to draw out the hot air so the insulation does not have to work as hard. Roof color helps as well. Lighter colors reflect heat.
Planting shrubs near the house on the sunny side also help draw the heat away from the home.
Can you use a smaller pump motor to filter the pool? larger motors use more energy then smaller ones. Check on the efficency of the motor as well. Newer motors use less power then some of the older ones.
Get a pool cover. This will prevent the need of the filter to run so long.
Check with the local utility company. Many do energy audits for free. Perhaps they can suggest some ways to lower your energy cost.

Just out of curiousity, what do you pay per KWH? I agree with Richard in that as a first step, you should have the electrical company do an analysis.
