Orders of magnitude, I used to have an all electric apartment, using a fan versus AC was a 25 dollar difference or more. I used to do the math, and nursing an iced tea down the road during the hottest four hours of the day, some days, could pay for itself, but that was before the rents skyrocketed as scores of cost indifferent international students moved in just as I was moving out.

(Last I was in the town I'm referencing, it had gone from 500ish walkable to campus to more like 1K and littered with those damn scooters.)
