June 10, 2009–Today’s Way: I just posted yesterday about opening up our homes to let the cool breeze in, and today I’m going to contradict myself.  Sort of.  When the weather turns really hot, you can keep your home cooler by closing doors and windows and shutting blinds or curtains during the heat of the day.  Then, at night when the air cools down, open up all of your windows.  When we practice this technique, along with employing our ceiling and window fans, we’re able to avoid using the air conditioner most of the summer.  At the same time, we use far less energy and save quite a bit on our electric bills.
