1. Door or Hatch
   Weather-strip or insulate your attic door or hatch to prevent air from escaping from the top of your house.
2. Insulation
   Check current insulation levels, and properly insulate a new or existing home. Insulate ceilings, walls, and floors over unconditioned crawl spaces.
3. Vents
   Attics must be venilated to relieve heat buildup caused by the sun. If necessary, improve attic airflow by adding or enlarging vents.

1. Heating Unit
   As much as half of your household energy use goes to heating and cooling. Replacing older equipment with more efficient equipment will reduce your energy costs. Tune up your heating system in the fall to make sure that it will operate at maximum efficiency during the cold winter.
2. Air Conditioning Unit
   Check and clean or replace air filters every month. Clean the outside condenser coil once a year. Schedule periodic maintenance of cooling equipment by a licensed service representative. A "tune up" in the spring will help the air conditioner run at maximum efficiency during the hot weather.
3. Water Heater
   Reduce your water heating bill by 10 percent by lowering the water heater temperature from 140 F to 120 F. (Keep the temperature at 140 F if you use an older dishwasher without a temperature booster.)
4. Once a year, drain a bucket of water from the bottom of the water heater tank. This gets rid of sediment, which can waste energy by "blocking" the water in the tank from the heating element.
5. Locate water heaters as close to the points of hot water usage as possible. The longer the supply pipe, the more heat that is lost.
6. Insulate your hot water supply pipes to reduce heat loss.
7. For older water heaters, consider buying a water heater insulation kit, which reduces the amount of heat lost through the walls of the tank.

1. Sink 
   To conserve water, use sink stoppers instead of letting water run while shaving.
2. Vanity Lights 
   Bathroom vanity lights are one of the most used fixtures in the average home. Use energy-efficient lighting, which can provide bright, warm light while using less energy and generating less heat than standard bulbs.
3. Shower 
   Install a new low-flow shower head to help you conserve water and save energy and save more than $75 each year on energy costs.
4. Toilet 
   A leaky toilet can waste 200 gallons of water per day. Be sure to repair all toilet and faucet leaks promptly.
5. Vent Fan 
   An ENERGY STAR ventilation fan will control moisture in the air while saving energy. These fans are much quieter than standard models. Fans with efficient lighting and fan motors use 65 percent less energy on average than standard models, saving $120 in electricity costs over the life of the fan.

1. Humidifier
   In the winter, the air is normally dry inside your house, which is a disadvantage because people typically require a higher temperature to be comfortable than they would in a humid environment. Therefore, efficient humidifiers are a good investment for energy conservation.
2. Lighting
   Provide task lighting over desks, tool benches, etc., so that activities can be carried on without illuminating entire rooms. Replace incandescent bulbs with energy efficient lighting.
3. Outlets
   Unplug any battery chargers or power adapters when electronics are fully charged or disconnected from the charger.
4. Cordless Phone
   ENERGY STAR qualified cordless phones that feature switch-mode power supplies and "smart" chargers add to your energy savings.

1. Light Switch
   Remember to always turn off the lights when leaving a room. Turning off just one 60-watt incandescent bulb that would otherwise be on for eight hours a day can save about $15 per year.
2. Thermostat
   Install a programmable thermostat to automatically adjust your home's temperature when you're away or sleeping.
3. Heating
   Locate the heating thermostat on an inside wall and away from windows and doors. Cold drafts will cause the thermostat to keep the system running even when the rest of the house is warm enough. Set the thermostat as low as comfort permits. Each degree over 68 F can add 2-3 percent to the amount of energy needed for heating.
4. Air conditioner
   Set your thermostat to 78 F, or as high as comfort permits. When the weather is mild, turn off the AC and open the windows.
5. Vents
   Make sure that drapes, plants, or furniture do not block registers for supply or return air.

1. Front Door 
   Install storm doors at all entrances of the house. Weather-strip and caulk around all entrance doors and windows to limit air leaks that could account for 15-30 percent of heating and cooling energy requirements.
2. Garage 
   Keep the overhead door of an attached garage closed to block cold winds from infiltrating the connecting door between the house and garage.
3. Outdoor Lights 
   Intall photoelectric controls or timers to make sure that outdoor lighting is turned off during the day. If using energy-efficient light bulbs, make sure that they are compatible with the controls.
4. Porch Light 
   Install energy-efficient lighting in the front porch light - one of the most-used lighting fixtures in a home. If your porch light is connected to a timer or photocell, make sure the new light bulbs are compatible with the controls.
5. Windows 
   Double-glazed windows (two panes of glass seperated by a sealed air space) cut heat transfer by 40-50 percent. Single-glazed windows should have storm windows. A wood or metal frame storm window provides a second thickness of glass and a layer of still air that reduces heat transmission markedly.

1. Dishwasher 
   Appliances account for as much as 20 percent of your energy bill. Newer, more efficient models save energy and water. If replacing your dishwasher, an ENERGY STAR model can save more than $25 a year in energy costs.
2. Sink 
   To conserve water, repair any leaky faucets promptly. Hot water leaking at a rate of one drip per second can waste up to 1,661 gallons of water in one year and wastes up to $35 in electricity.
3. Refrigerator/Freezer 
   If your current refrigerator was made before 1993, it uses twice as much energy as an ENERGY STAR model.
4. Keep your refrigerator at 37 to 40 F and your freezer at 5 F.
5. Vacuum the condenser coils (underneath or behind the unit) every three months.
6. Check the condition of door gaskets by placing a dollar bill against the frame and closing t he door. If the bill can be pulled out with a very gentle tug, the door should be adjusted or the gasket replaced.
7. Do not put uncovered liquids in the refrigerator. The liquids give off vapors that add to the compressor workload.
8. Microwave 
   Use your microwave oven whenever possible. It draws less than half the power of its conventional oven counterpart and cooks for a much shorter amount of time.
9. Range/Oven 
   Only use pots and pans with flat bottoms on the stove. Use the right-sized pot on stove burners. A six-inch pot on an eight-inch burner wastes more than 40 percent of the burner's heat.
10. Develop the habit of "lids-on" cooking to permit lower temperature settings. Keep reflector pans beneath stovetop heating elements bright and clean.
11. Begin cooking on highest heat until liquid begins to boil. Then lower the heat control settings and allow food to simmer until fully cooked.
12. Cook as much of the meal in the oven at one time as possible. Variations of 25 F still produce good results and save energy.
13. Rearrange oven shelves before turning your oven on-and don't peek at food in the oven? Every time you open the oven door, 25 F to 50 F is lost.
14. Trash 
    Recycle your newspapers, plastic and glass containers, and paper products.

1. Clothes Dryer
   Use the moisture sensor option so that the dryer turns off automatically when clothes are dry. Or, dry your clothes on a clothesline outside.
2. Clothes Washer
   Wash only full loads of laundry. Wash clothes in cold water. Sort laundry and schedule washes so that a complete job can be done with a few cycles of the machine carrying its full capacity, rather than a greater number of cycles with light loads.

If you're looking to buy a new washing machine, consider using a front-loading or horizontal axis machine. These new units use 30 percent less water and 50 percent less energy to make hot water and wash clothes than regular washing machines.

1. Ceiling Fan 
   In the winter: If your ceiling fan has a switch that allows you to reverse the motor, you can operate the fan at a low speed in the opposite direction. This produces a gentle updraft, forcing warm air near the ceiling down into the living space. In the summer: Run the blades counter-clockwise (downward) to cool more efficiently. Turning up the thermostat by just two degrees and using your ceiling fan can lower AC costs by up to 4-6 percent over the course of the cooling season. Don't forget to turn the ceiling fan off when you leave the room.
2. Fireplace 
   Make sure your fireplace has tightly fitting dampers that can be closed when the fireplace is not in use. Seal hidden air leaks in your chimney.
3. Lamps 
   Put lamps in corners of rooms where they can reflect light from two wall surfaces instead of one. Use compact fluorescent bulbs in fixtures that are on for more than two hours a day. Compact fluorescent bulbs use up to 75 percent less electricity. They also last about 10 times longer.
4. Entertainment Center 
   The average homes uses 25 electronic products, accounting for up to 15 percent of household electricity use. Turn these products off when they're not being used. Better still, switching to electronic equipment with the ENERGY STAR label will help save additional energy even when the device is turned off.
5. Windows 
   In warm weather, close your blinds and curtains during the hottest part of the day. During cold weather, keep curtains open during the daylight hours to take advantage of the sun's warmth.

1. Computer and Monitor 
   Do not use a screen saver when your computer monitor is active. Instead, let it switch to sleep mode or turn the monitor off.
2. Printer, Fax, Copier 
   Save energy and space with a multi-function device that combines several capabilities- such as print, fax, copy, and scan. Enable power management features for additional savings. Turn off machines when not in use.
3. Set office equipment to automatically switch to sleep mode. 
   This will help equipment to save energy, to run cooler, and to last longer.
4. Power Strip 
   Use a power strip as a central "turn off" point when you are finished using equipment. This will help eliminate the standby power consumption used by office equipment even when it is turned off.

Many of your once-a-year spring cleaning chores can save energy all year round. Some examples:
 

1. Clean windows inside and out. The cleaner the panes are, the more sunlight can shine through them, making it less necessary to turn on lights and run space heaters in the spring.
2. Replace the air filters in your HVAC system. If they’re full of dust, dirt and pet hair, air will have a hard time passing through them. Poor airflow makes your air conditioner work harder to do its job.
3. Clear fallen branches and leaves and other debris that might have fallen on the outdoor unit of your air conditioning system over the winter. For the unit to work properly, air needs to circulate around it.
4. Climb a ladder and dust ceiling fan blades. When the fan starts running, it can knock accumulated dust into your room, which is bad for air quality and can wind up in in your air conditioning vents or filters.
5. Snake your dryer vent or hire a pro to do it for you.
6. Pull your refrigerator slightly out from the wall and vacuum behind it. If your fridge has exposed coils, vacuum those, too.
