5. GO PAPERLESS AT THE ATM. (If every American opted not to print ATM receipts, we would save more than 2 billion feet of paper— enough to circle the equator 15 times—every year.)
6. PICK PANS THAT FIT YOUR BURNERS. Matching your pots and pans to the size of your burner is more energy-efficient than choosing them based on the amount of food you’re cooking. According to the U.S. Department of Energy, cooking with a 6-inch pan on an 8-inch burner wastes 40 percent of the burner’s heat.
EVEN GREENER: To cook using the least amount of energy, pick pots and pans with flat bottoms (they’ll cover more surface area) and lids. And look for cookware made with copper or aluminum— materials that heat up faster than stainless steel.
7. DRY YOUR RAZOR BLADE AFTER EACH USE. The Environmental Protection Agency estimates that Americans toss out 2 billion disposable razors and blade cartridges every year. You can double the life span of your blade, which becomes blunt due to microscopic rusting, by patting it dry after each use, according to research from an independent lab in Yonkers, N.Y. To further protect your razor from humidity that can cause rust, store it outside the bathroom or in a sealed cosmetic case.
EVEN GREENER: Use an environmentally friendly razor like Preserve’s, which has a handle made from 100 percent recycled plastic ($7.25 for 4; recycline.com).
8. TAKE A ONEMINUTE- SHORTER HOT SHOWER. (You’ll keep 170 pounds of carbon dioxide from entering the atmosphere.)
