Last summer, I finally caved and bought an air conditioning (AC) unit for my apartment living room. With my job fully remote and a very hot summer season in LA across 2022, it was money well spent - no longer did I sweat at my desk in the afternoons.
Unfortunately, no good deed goes unpunished - I quickly realized that the AC unit consumed significantly more energy than the rest of my apartment put together! In turn, my electricity bills jumped up from the $40ish/month range to the low hundreds - quite a bit of money.
