Home appliances can add to or detract from a home's overall energy efficiency, and they always have two price tags: purchase price and costs for the energy (and water) they require to operate.
The best way to know that a home appliance is designed with energy efficiency in mind is to look for the ENERGY STAR® label or search for internationally recognized labels. This label means that a product meets strict energy-efficiency guidelines set by the U.S. Environmental Protection Agency and the U.S. Department of Energy. Efficient appliances incorporate advanced technologies that use 10 to 50 percent less energy and water than older generation models. The money saved on utility bills can more than make up for the cost of buying the more efficient model.
It is important to remember that operational costs can be substantial – is it currently estimated that appliances account for 13% of your home’s energy bill. Fortunately, there are many steps you can take to maximize the efficiency of your current appliances, and you can get started with the tips listed here.
