Q: How much electricity do new windows save?

Does replacing all the windows in a house result in a big energy savings or just a modest one?

I live in Baltimore, Maryland, where it is muggy in the summer and cold in the winter. We use a good amount of air in the hot months and pretty heavy amount of heat in the cold ones. For your reference, the house is ~2,000 sq ft and two stories with a finished basement (heat and air go in there too, obviously). We would definitely love to make the house more "green friendly". And, replacing the windows is one of the moves that seems to make sense; however, it isn't exactly cheap to replace all the windows in the house. We would love to know how this improvement stacks up on both the green scale and the dollar savings scale. Thanks.

    Changing your windows out helps a lot. I reconmend double pane marvins, anderson or any repitual window manufactor. This helps by reducing your heating and cooling wich in return will lower your carbin foot print by useing less energy to heat or cool your house. This is Pretty exwpencive up front but it will creat a huge savings in the long run. While your at it you should consider changing all light bulbs to the energy effisiant bulbs including exterior lights (flood bulbs ). Home depot has them pretty cheep (five bucks for five or four ). This helps a lot too and is easy to do. Anyway I won't waist anymore of your time if you want to know more green tips that are simple and fair on the pocket book just post another question and I will be happy to help.
