Every one wants to save money. There are multiple ways to save money on your utility bills like close you fireplace, change your light bulbs, purchase energy efficient appliances, seal leaks, etc. However the easiest and most efficient way to save on your utility bill in our opinion is to buy drapes for the windows. If you live in an older place there is a high likelihood that the windows are letting hot air out or letting cool air in. Window drapes will help prevent this air from passing or escaping. Your utility bill should be less if you seal the windows and put drapes on them.
