Just a thought on refrigeration...
I live in Savannah, GA and am also very frugal. This presents a problem because Savannah gets a little warm in the Summer and turning on the AC can triple the electric bill. It is now in the low 90s and we still haven't turned on the AC. Our house is 2-stories tall over a crawl space, except for the kitchen, which is a single-story addition over a crawl space. Our landlord went with the lowest bidder for HVAC and it really shows. The kitchen's temperature swings wildly depending on what the outside temperature is.
The refrigerator is a blessing in the winter because it pumps heat into an otherwise chilly room. In the summer, however, it is like putting a blast furnace in a sauna! I wish there was a way to vent the heat from the fride out of the house in the summer and retain it in the winter. Heck, in the winter why not just vent the cold air outside directly into the fridge if it is cold enough?
In the summer, the fridge removes heat and dumps it into the house, from which it must be removed by the AC. In the winter, the fridge must keep itself cold in an artificially warm room. There has got to be a better way that would be less counter-productive!
Ahh seasonal fustration,
