Here in the North East USA the only time that I use air conditioning is for 2-3 weeks or so in the hottest part of the summer. The rest of the summer it's nice to have open windows with screens to allow the fresh air to come in the house. A screen door allows that much more fresh air into the house.
In the winter the storm door does not lend much insulating value, but it does block the wind from hitting the main door. Older homes also have removable 'storm windows' to supplement their single pane main windows. These are framed glass that help block the wind from hitting the main windows. Newer homes though have thermo pane windows (insulated glass) and generally do not need the 'storm window' but do come with removable screens.
