You've made the investment in new energy efficient appliances and you are seeing the difference in your utility bills. Have you fully taken advantage of Energy Star?
Many States still give rebates. Also if you recycle your old appliance properly you get an extra rebate. That makes the upgrades that much sweeter.
I would hope that the store that sold your appliance helped you get started to get your rebate.
You can also check http://www.ecorebates.com to see how much your state is allocating for Energy Star rebates.
You can also get more info on the Energy Star Web Site.
As always have your receipts ready.
