Eligible participants can receive rebates for replacing older appliances with EnergyStar-certified appliances, a result of funding from the American Recovery and Reinvestment Act of 2009. Each state designed its own program, and the Department of Energy served as an umbrella organization, recommending a focus on these items: boilers, central air conditioners, clothing washers, dishwashers, freezers, furnaces (oil and gas), heat pumps (air source and geothermal), refrigerators, room air conditioners and water heaters. Replacing old appliances with new, more efficient ones can result in significant savings on utility bills and also benefit the environment. (Source: DOE / Photo: Flickr)
