If you're in the market for new home appliances, you're probably focused on the upfront price. But those machines in our kitchens, laundry rooms, and basements use energy -- up to about 20% of our total home use -- and, in some cases, water Looking for the most efficient models of a new dishwasher, refrigerator, washing machine, or air conditioner can help you lower both your environmental footprint and your utility bills. At minimum, check for Energy Star and, when appropriate, Water Sense certifications to ensure you're not locking yourself into higher energy and water use than needed.

Buying green appliances

• Energy Star and Water Sense certifications are strong indicators of efficiency, but also check Consumer Reports' Green Ratings for direct comparisons of brands and models.
• See how the manufacturer's environmental and social responsibility record stacks up to its competitors at Responsible Shopper.
• Make sure you dispose of old appliances responsibly. Nearly 90% of appliances are now recycled; if the seller of your new model won't take care of this for you, check Earth 911 for recycling options. If your old appliance is still running, considering donating it.

Buying tips for specific appliances

• When shopping for a refrigerator, consider skipping the ice and water dispensers: they can increase energy usage by up to 20%. Top mount or bottom mount models tend to be slightly more energy efficient than side-by-side, and also last longer.
• The water and energy used by dishwashers can vary greatly, so the most efficient models can create significant savings over the life of the product.
• Front-loading washing machines are generally more efficient than top loaders... but also the most expensive.
• A gas-powered dryer with a moisture sensor will save the most energy.
• The efficiency of air conditioners is measured by its energy efficiency ratio (EER). A higher EER means a more efficient model... but also consider the size of the space you want to cool.
• Radiant space heaters are more efficient that convection models, but you must be located directly within their "line of site."
