i did that too. i printed the monthly rates table since the unit rate changes depending on the monthly consumption, but also i include the 13% VAT percentage for residential usage, and it adds up to 0.15$/kwh. my ac consumes about 1.2kwh per hour, and i plan running it 20 hours per day for 60 days. women dont like accountability and dont like to admit to consequences. good on you for staying wise and planning everything in advance.
to be fair to OP, I have only seen this done by women, too.
When you have to explain to an adult woman that leaving the heater on max is like opening the faucet in the sink, and leaving the house, maybe it's not a surprise that it causes her to have a nervous breakdown. (since if she was a rational thinker, she wouldn't be doing it in the first place)
Still weird that I have never seen this done by a man.
