TIP: Replace your single-paned windows with double-pane windows.

This can be an expensive home renovation, but it will make all the difference in the world in terms of saving you energy during the cold winter months. The American Council for Energy Efficiency has a website on selecting the best energy efficient windows for your home. In addition to double panes, energy efficient features to look for on windows include tinted glass coatings, low-emissivity (low-e) coatings, and multiple layers of glazing.
