Refrigerator payback

My current fridge (a Hotpoint Foodcenter 24) is older than I am. It was originally the avocado color shown in the ad; at some point someone painted it black but only the front and the sides they could reach; the top back and sides were not. The spread control is appreciated but not used. The giant dust bunnies of a never cleaned coil underneath was not. I measured the yearly annual cost of this fridge at $290 a year with a kill-a-watt; at that rate, a really nice replacement will begin paying for itself in six years. The previous owners had this fridge for 15 years and paid over $4000 in electricity for the privilege.

7.72 microRads/hr

A 39 day long sampling of every minute leads the geiger counter to a long term average of 7.72 uR/hr. That's 56658 sampling points. That's about what's it's always been.
