Traveling for the holidays? If you're staying at a hotel, a small gesture that makes a big difference in water savings is hanging your bath towel on the rack instead of throwing it on the floor. Many hotels are now participating in towel reuse programs. That means that during your stay, a towel on the rack will be used again. The cleaning staff knows not to wash it unless it's on the floor. This simple act can save the average 150-room hotel 72,000 gallons of water, 39 barrels of oil, and 480 gallons of detergent over the course of a year.
