EH2ED Day Four: Brusha, Brusha Brusha

Turn off the faucet while you brush your teeth. You'll save up to 2.5 gallons of water each time you brush your teeth - up to 150,000 gallons over a lifetime.

ED2eH Day Three: Recycle Paper

ED2EH Tip: Americans toss out about 35 million tons of paper each year. Buck the trend and start recycling -- not only standard white printer paper, but all of the receipts, phone messages, and colored post-it notes that decorate your space. Recycled paper manufacturing generates 74 percent less air pollution, and saves trees, water, and energy.

ED2EH Day Two: Buy CFLs

Now that your lights are back on, replace them with compact fluorescent light bulbs (CFLs), which require only 25% of the electricity used by incandescent bulbs. According to the federally backed Energy Star program, if every household in the U.S. replaced one light bulb with an Energy Star-qualified compact fluorescent bulb, it would equal removing 1 million cars from the road. CFLs are more expensive initially, but because they last so long, they end up saving you money. Especially target the 60W to 100W bulbs you use several hours a day. To learn more about CFLs and to find out where to purchase them, visit the Energy Star Web site.
