As per the department of Energy, every appliance comes with two price tags: the actual price for buying and its operating costs.
The Energy Star® logo ensures that the appliance meets the standards mentioned by federal authorities as far as energy saving is concerned. The Energy star calibrated appliances include water heaters, windows, washing machines, dishwashers, refrigerators and basically all appliances that consume electrical energy in home usage.
Additionally, the government has made it easy for the average consumer to understand the operating cost of every appliance. This is done in the form of a bright yellow and black energy guides that list which appliance is energy efficient along with the estimated operating cost of each appliance.
Remember that most appliances we use daily account for nearly 15% of the household's energy expenses. Appliances like refrigerators, laundry machines and dishwashers top this list. So it helps if you or your landlord agrees to installing energy efficient appliances as these help pay for themselves in the long run. Many smart appliances are also available today and these automatically shift use to off peak hours thus saving a great deal of money.
