Our electric bill for last March was $122. Our bill for August was $279. Doing some rough math, this means the air conditioner accounts for about $5.25 a day, or $157 a month.

The finance nerd in me looks at that $157/mo savings as a possible future stream of earnings. That is, if I took that money and invested it in something earning 5% a year compounded annually I’d have $255 at the end of 10 years. That kind of thing.

The foodie in me looks at that $157 and thinks, “That’s at least two no-holds-barred trips to Seito; apps, a boat, booze, and the banana tempura thing for dessert”.

The realist in me knows that money will instead end up going to a doctors bill or to Nick Urgo or food for a party or a replacement router or any one of dozens of different unexpected things. But, for a few shining moments, cooler weather brings free money.
