How do you perform an energy audit? Is that something the electric utility company will do?
I am not sure. In some areas... yes. At one time the local power co. provided a very nice audit at no cost... then at low cost. I am pretty sure federal dollars have been pumped into many such organizations that now do local energy audits as well as seal and such. You could check your local (digital) yellow pages.
But since "
your sure" the pool heater is off (I'd lock its breaker to off). And the hot water is gas... you could do your own with a
energy reading device. That will allow you to
check refrigerators, freezers, as well as other devices... AND
inspect every plug and electric device in the house... all in part of a weekend morning.
Solar (PV) can easily be mounted on a steel stand or support. That would save your roof and can be hidden behind landscaping or the home as well.
I don't advocate environmental issues! But I don't consume a lot of resources myself. I've replaced my nighttime landscape lighting with LED lights (hardwired AC bright ones, not solar) with motion sensing floodlights and cameras for added security. The operating costs are near nothing.
Out of the way inside lighting that could be forgotten and left on Like the garage and laundry room, I've replaced with motion sensors (not X10). We don't have pets that shed and clog condenser coils in our freezer or refrigerators... but I still vacuum them clean twice a year. I use the time-change at spring and fall as a reminder. I also use my compressor to blow clear my electronic air filter then... and seasonally replace the paper filters.
I am sure... with or without X10.... your can get a handle on your power useage. Even at three times normal [mid-western] costs your spending more than twice what I would expect. Your cost is 14+ times of mine....
of course I don't have a pool. But I do have hellishly hot and humid summers and subzero winters. Find out what is costing you what... and then you can make good decisions based on solid math.
