You probably will not save at the time of purchasing energy-efficient appliances for your home, unless you do so in time to take advantage of federal income tax credits or other state and local government or utility company incentives.

You can, however, expect to save money on the operating costs for those appliances in a lower electric/gas bill for the forseeable future. The amount you will save by upgrading depends on how efficient or inefficient your current appliances are and which new models you choose. For example, if you choose a top loading washing machine with an Energy Star rating, you will not save as much as if you buy a front loading washing machine with an Energy Star rating. If you are willing to make some changes, compromise some features for efficiency, you should be able to expect a marked increase in efficiency.
