I just got a drying rack and am trying a version of this. I'm trying not to use a dryer when the A/C is on. So during this heat wave, it's from 9am-9pm. During that time, I line dry. That way I'm using less power, using it at off-peak times, not heating up the house, and saving money. I would line dry everything, but we do a lot of laundry in my house. However, I am line drying 2/3 of my laundry now, and that's a start!
