Energy Conservation Tips

» Conservation in Lighting

  • Don't leave lights on when no one is in the room. If you are going to be out of the room for more than five minutes, turn off the light.
  • Where possible, use compact fluorescent light bulbs. Those funny-looking bulbs produce the same amount of light by using 1/4 of the electricity. Plus, they last for years and years without burning out.
  • Replace flickering, dim and burned-out lamps
  • Keep light fixtures clean - a cleaner bulb is a brighter bulb
  • Lower overall energy demand by concentrating bright light where you need it rather than evenly lighting the entire room - this is called 'task lighting'
  • Lower the height of light fixtures if possible to increase usable light.
  • Replace burned out lamps with lower wattage lamps or energy-saving lamps wherever possible.
  • Install more efficient security and parking lot lighting. High-pressure sodium fixtures are more efficient than metal halide, mercury vapor, fluorescent or incandescent fixtures.
  • Install time clocks or photoelectric cells to control exterior lighting, advertising sign lighting and some interior lighting.
  • Paint dark walls and ceilings with lighter colors to maximize the effect of existing light sources.
  • Maximize natural lighting by installing skylights or windows.
  • Install dimmer or occupancy switches where appropriate to lower energy use such as in stairwells, copy rooms, restrooms.
  • Implement a group re-lamping schedule, and re-lamp at 70% of rated lamp life. Lamps that run longer than 70% of their rated life actually cost more in terms of energy use.
  • Trim bushes and trees away from outdoor lighting to maximize illumination and prevent shadows.

» Energy Conservation at Home

  • Keep refrigerators and freezers out of direct sunlight, and allow at least 5 centimeters all around (or as recommended by the manufacturer) to allow heat to escape from the compressor and condensing coil.
  • Clean your refrigerator's coils (back) and air intake grill (below the doors) every 3 months.
  • Don't let freezers build up more than 6 mm of frost. Defrost regularly to keep freezers working their best.
  • Allow hot foods to cool before putting them in the refrigerator.
  • Use kitchen, bath, and other ventilating fans wisely; in just 1 hour, these fans can pull out a houseful of warmed or cooled air. Turn fans off as soon as they have done the job.
  • 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.
  • Turn off the TV when no one is watching it. The same goes for computers, radios and stereos - if no one using it, turn it off. Turn off all the appliances at the surge protector/control strip - that four- or six-plug extension chord that you plug all your computer things into.
  • Wasting water wastes electricity. Why? Because the biggest use of electricity in most cities is supplying water and cleaning it up after it's been used!
  • If you need to warm up or defrost small amounts of food, use a microwave instead of the stove to save energy.
  • Don't keep the refrigerator door open any longer than you need to. Close it to keep the cold air inside! Also, make sure the door closes securely.
