No hint of lint.
Clean your dryer lint screen with every use and don't overload the dryer.
You'll save up to 5 percent on your electricity bill -- which could mean an energy-equivalent savings of 350 million gallons of gasoline per year if everyone did this. Also, run your dryer during off-peak hours. Check with your utility company to see if they offer discounted rates during off-peak hours and verify when those hours are. Better yet, use a clothesline.
