In with storm windows, and out with the screens

Fall is here. We spent much of the morning "battening down the hatches" as Cheap-o-Dad calls it. Translation: putting in the storm windows for insulation. In past years, we've been a bit lazy and have just left the screens in during winter (we have mostly old single pane double-hung wooden windows, but with newer storm windows built over them). However, I read recently that you get better passive solar heating if you take out the screens for fall/winter. So we did that too. Man, what a difference. I know I really want that extra light and heat as we head into this cold and gray time of year. We also raised all of our blinds on the eastern and western sides of the house, again, so as much light can shine in as possible (yes, we are very lazy, and we only put them all the way up this time of year, and only fully lower them on really, really, really hot days).
