    Double-paned windows can save you anywhere from 7-24% on your energy bills over a given year. The equivalent amount of energy is saves you by switching to an EnergyStar approved double-pane window is somewhere between 980-4,500 pounds of carbon dioxide depending on how much energy you use in your home. Double-pane windows increase the insulation in your house by providing a buffer space between the panes of glass, which helps keep in the warmth and out the cold during the winter, and vice versa during the summer. This saves energy as far as heating and cooling your house goes, because you can cut back on how much energy you actually use in order to get your house to the right temperature
