I get it. This summer I bought a battery bank and portable solar panels so I can a) take some load off a circuit that is overtaxed in the summer and b) be able to very slowly charge the car in the event of an emergency.

A month after getting it, we got a notice on our door that they were working on poles and our power would be out for 8 hours. I kept my whole homelab, and refrigerator running the whole time and the entertainment center running most of the time. Any thought that I spent too much, given the probable utility, immediately disappeared. I wouldn't call it pride in my decision, but it came damn close.
