When you decide to replace old appliances, be sure to choose the most energy-efficient new models available. Look for the “Energy Star” label, so that you may be assured that what you buy saves energy and prevents pollution.
In addition, be careful to buy models of the right size for your needs—not the biggest available.
Be aware that front-loading washers can cut hot-water use by up to 60 to 70%.
Replacing a typical 1973 refrigerator with a new, energy-efficient product saves 1.4 tons of CO2 a year; a solar water heater can save 4.9 tons of CO2 annually.
