6. Heating and Cooling Typically, 44% of your utility bill goes for heating and cooling. Also, heating and cooling systems in the U S emit: 1.over a half billion tons of CO 2 / year adding to global warming. 2. They also generate about 24% of the nation's sulfur dioxide and 12% of the nitrogen oxides, the chief ingredients in acid rain.

7. Insulation and Weatherization The easiest and most cost- effective way to insulate your home is to add insulation in the attic. Most U.S. homes should have between R-22 and R-49 insulation in the attic. Conserving Heating and Cooling Energy

8. Solar Heating and Cooling Using passive solar design techniques to heat and cool your home can be both environmentally friendly and cost effective. What is passive heating: Passive solar heating techniques include placing larger, insulated windows on south-facing walls and locating thermal mass, such as a concrete slab floor or a heat-absorbing wall, close to the windows.

9. Fireplaces If you never use your fireplace, plug and seal the chimney flue. Keep your fireplace damper closed unless a fire is going. When you use the fireplace, reduce heat loss by opening dampers in the bottom of the firebox (if provided) or open the nearest window slightly Install tempered glass doors and a heat-air exchange system that blows warmed air back into the room.

10. Cooling Tips 1. Whole-house fans help cool your home by pulling cool air through the house and exhausting warm air through the attic. 2. Set your thermostat as high as comfortably possible in the summer. 3. Don't set your thermostat at a colder setting than normal when you turn on your air conditioner. 4. Consider using an interior fan in conjunction with your window air conditioner to spread the cooled air more effectively. 5. Don't place lamps or TV sets near your air-conditioning thermostat. 6. Plant trees or shrubs to shade air-conditioning units but not to block the airflow. A unit operating in the shade uses as much as 10% less electricity than the same one operating in the sun.

11. You can save as much as 10% a year on your heating and cooling bills by simply turning your thermostat back 10% to 15% for 8 hours. You can do this automatically without sacrificing comfort by installing an automatic setback or programmable thermostat.

12. Water Heater There are four ways to cut your water heating bills: 1.Use less hot water 2.Turn down the thermostat on your water heater, 3.Insulate your water heater, 4.Buy a new, more efficient water heater.

13. 13 A family of four, each showering for 5 minutes a day, uses 700 gallons of water a week; this is enough for a 3- year supply of drinking water for one person. You can cut that amount in half simply by using low-flow showerheads and faucets.

14. Windows Cold-Climate Window Tips Double-pane windows with low-e coating on the glass reflect heat back into the room during the winter months. Install exterior or interior storm windows; Close your curtains and shades at night; open them during the day. Keep windows on the south side of your house clean to maximize solar gain.

15. Landscaping Landscaping is a natural and beautiful way to keep your home more comfortable and reduce your energy bills. In addition to adding aesthetic value and environmental quality to your home, a well- placed tree, shrub, or vine can deliver effective shade, act as a windbreak, and reduce overall energy bills.

16. Lighting Use linear fluorescent and energy-efficient compact fluorescent lamps (CFLs) in fixtures throughout your home to provide high-quality and high-efficiency lighting. Fluorescent lamps are much more efficient than incandescent bulbs and last 6 to 10 times longer.

17. Appliances When you do have to shop for a new appliance, look for the ENERGY STAR 7 label. About 80% to 85% of the energy used for washing clothes is for heating the water. There are two ways to reduce the amount of energy used for washing clothes C use less water and use cooler water. Refrigerators with the freezer on top or bottom are more efficient than those with freezers on the side. When you're shopping for appliances, you can think of two price tags. The first one covers the purchase price C think of it as a down payment. The second price tag is the cost of operating the appliance during its lifetime.

19. 19 CAFÉ Standards Corporate Average Fuel Economy (CAFE) is the sales weighted average fuel economy, expressed in miles per gallon (mpg) Applies to passenger cars or light trucks with a gross vehicle weight rating (GVWR) of 8,500 lbs. or less Administered by the Secretary of Transportation who has delegated authority to establish CAFE standards to the Administrator of the National Highway Traffic Safety Administration (NHTSA)
