On Lighting
1. Turn off lights when not needed. Clean lamps or bulbs regularly to get more light. Dirt and grime can cut down illumination by as much as 50 percent.
2. Use low-watt lamps or bulbs whenever feasible.
3. Business offices and factories with over lighted areas (where lighting is not a critical factor) can deactivate a tube or two in fluorescent fixtures by simply unscrewing the starters.
4. Sports activities can be limited to daytime.

On Air Conditioning
1. Maintain thermostat setting at a temperature not lower than 75 deg Far. (23.9 deg. Celsius). Always have a thermostat in cooling appliances.
2. Keep thermostat efficient.
3. Locate air conditioning units in the coolest side of the rooms.
4. Keep the air conditioner's filters, condenser, evaporator, etc., clean.
5. Proper insulation cuts air conditioning costs; use blinds, shades or draperies to block direct sunlight.
6. Doors must be kept closed at all times.
Lighting

    * Use natural light whenever possible.
    * Turn off lights when not in use.
    * Use compact fluorescent lights (CFL) instead of incandescent bulbs. A 16-watt CFL produces the same light as a 60-watt incandescent bulb at a quarter of the energy cost.
    * Clean bulbs regularly. Dirt lessens illumination by as much as 50%. Use low wattage light bulbs in areas that do not need strong lighting such as hallways, foyers and doorways.
    * Use lamps that provide direct lighting over desks, beds and other work areas. Using them saves energy instead of the higher wattage lighting used to illuminate the whole room.

    
 Refrigerator

    * Give it room to breathe. Place refrigerators at least 4 inches away from the wall so as not to overwork the motor.
    * Clean condenser coils. The coils at the back remove heat.
    * Clean it twice a year using a vacuum cleaner or broom.
    * Check door gaskets. Make sure refrigerator doors are sealed tightly to prevent cold air from escaping.
    * Defrost regularly. Defrost before frost builds up to 1/4 inch to keep refrigerator running efficiently.
    * When buying new refrigerators, be sure to purchase energy efficient models.
    * Look for units with the highest Energy Efficient Factor (EEF). It is more efficient and costs less to operate.

    
Cooking

    * Plan ahead. Prepare all ingredients before cooking to avoid frequent switching of electric stove.
    * Thaw frozen food thoroughly before cooking. Match pots and pans to stove element. Avoid using a big burner for a small pan to lessen heat transfer loss.
    * Cover pots and pans. Cover pots with lids to prevent heat from escaping.
    * Use flat-bottomed pots and pans when using electric stove. They provide faster heat transfer.
    * Switch off. Turn off the electric stove during the last minutes of cooking. The remaining heat will make the food simmer.
