In a recent article on the website Off the Grid News, several energy myths were listed and busted. One in particular stood out because some people I know (one of my sons specifically) will leave fans running in unoccupied areas ALL the time.
MYTH: Leaving
fans on in summer when you leave the house is a good way to keep rooms cool.
After all, if you allow your home to heat up while you are away, you will have
to use extra energy to cool it down again once you return.
This is not true – fans move the air, but they don’t really cool it, and leaving
them on when no one is around is a waste of time, money, and energy. There are a few
exceptions like when controlling humidity during the summer by drawing cool air
from an underground area to prevent mold.
