You can use the Energy Star label is a good way to ensure that you are getting the most efficient appliances for your home. The Energy Star label and standards apply to DVD players, dishwashers, dehumidifiers, and other home appliances.
Every decision you make when you buy or replace a home appliance, adjust your heating system, or replace a burned-out light bulb affects the environment. Most home electricity is generated by burning polluting fossil fuels, so the energy we use in our homes creates more greenhouse gas than is created driving our cars. Poor quality appliances use a lot of resources since they need to be replaced more often, and add to landfill waste. Inefficient appliances are bad because they not only cost you more money to own, but are bad for the environment. I Energy efficient appliances can save families up to a third of your energy bills, with corresponding savings of greenhouse gas emissions.
Consider both purchase price and estimated energy use when deciding which brand and model to buy. In many cases, you may actually save money by buying the more expensive, more energy-efficient model. You may also qualify for special energy-efficient offers, which may include cash rebates, low-interest loans, tax credits, or other incentive to encourage buyers to purchase energy-efficient appliances. The salesperson or local utility should have information about programs available in your area.
Read the Energy Guide label. This yellow and black label is attached to all new appliances, and discloses the estimated annual energy consumption for the appliance. This helps you compare the efficiency or annual energy use of competing brands and similar models.
