7 Energy Savings Tip You can save 4% to 9% of your water heating bill and reduce stand by heat loss by 25% to 50% if you have an older water heater just by putting a sweater on it. Well, not really a sweater, but a blanket or jacket covering made of special insulation. 7

(FOCUS ON GREEN BUILDING) 16

17 Labeling Wisdom If you call a dog s tail a leg, how many legs would the dog have? Five! No. Calling a dog s tail a leg doesn t make it a leg. 17
