Frigidaire AGQ6700FS Affinity Front Load Gas Dryer (white)

Dryers used to be tumbling hot boxes that liberated housewives from having to line-dry clothes and iron everything. Now dryers have grown up to be more energy-efficient and include new sensors and settings that protect clothes from one-size-fits-all high heat. They can even produce wrinkle-free clothes--no iron needed. And most are sold in stylish, modern, or colorful sets with matching washing machines that can be arranged side-by-side or stacked. The basic types of clothes dryers you'll find when you start your appliance hunt are gas-powered and electric-powered.

Much of going "green" with your clothes dryer choice has just as much to do with how you use your dryer as what kind of model you buy. For example, using your dryer's settings properly to make sure you don't overdry items, hanging delicates out to dry, and cleaning the lint filter after every use. Along with those tips, here's how to shop for a more energy-efficient model:

Consider gas models and models with sensors: Gas dryers are known for being more energy efficient and sensors are helpful with shutting off when the clothes are actually dry (not fried).

Get a higher spin washer: Dryers actually aren't regulated by the government and don't have to come with EnergyStar or EnergyGuide labels. But one tactic is to buy a washer that comes with a higher-speed spin cycle that will wring more water out of clothes and require less drying time.

Auto-dry: Use your model's auto-dry setting for the type of clothes you're drying vs. timed dry. Also keep the laundry loads flowing and dry loads one after another if you can to take advantage of the warmed-up drum.

Resource-saving cycles: Look for models that include features such as dual temperature heating elements to maintain and lower heat as needed.

Most gas dryers cost $50 to $100 more than their electronic counterparts, but they are more cost effective over time. The only hitch is that you need a gas hookup in your laundry area to install a gas dryer.

• Price: $350-$3,300
• Power requirement: Gas line
• Who it's best for: Budget-conscious homeowners who want to save money over the long haul and can afford to install the necessary gas line.
