I love reading posts about saving energy! Let me suggest looking at your fridge (without spamming up your post with too much detail): Commercial refrigerators gobble up power like crazy. This guy I knew built his own using one of those DIY kits they sell for boats. He used a giant cedar wood box, with 15 cm thick (!) insulation in the walls and the door, using material left over from building his roof. Also, the compressor was separated from the decompressor and moved... of course: to heat the smallest room of the house. He added a very efficient motor to move the gas, and in the end his fridge used less than 15 kWh a month.
But even if you don't want to re-build your fridge, keep it stocked with lots of liquids (if nothing else jars of water - or better: kombucha). The mass keeps the temperature down, so the fridge won't have to turn on every so often.
