Can not convince wife about two things. Just want to bring it here for
a serious judgement:

1. Use Air conditioner for home at night:
Temperature outside = 69F, Temp in home = 81F,
Air conditioner trigger set to 75F

method A. With windows being open - My way
method B. With windows being closed - Wife's way

Question: which one make house temp drop faster and which one costs
less electricity?

2. Use AC for car in a hot summer day
Temperature outside = 80F,
Temp of a car parked in sun for one hour = very hot, don't know
exact temp

After getting into the car
Method A: open windows, drive for a moment then close the windows
and start AC. - mine
Method B: Start AC right away without opening windows. - wife's

Question: which one make car temp drop faster and which one costs
less electricity?

Thanks!
