Energy Conservation Tips – LIGHTING



The costs of lighting can add up to more than one fifth of your electric bill.

Here are some tips for using your lighting most efficiently:



Indoor Lighting Tips

  • Take a look at how your lighting is arranged. If possible, put your table and floor lamps in the corners, where the light will reflect off two walls instead of one.
  • Use natural lighting whenever you can. Keep blinds and drapes open during the day so that you don’t waste energy.
  • Consider installing timers, photo cells, or occupancy sensors to reduce the amount of time your lights are on.
  • Use task lighting; instead of brightly lighting an entire room, focus the light where you need it. For example,
    use fluorescent under-cabinet lighting for kitchen sinks and countertops under cabinets.
  • Consider three-way lamps; they make it easier to keep lighting levels low when brighter light is not necessary.

Outdoor Lighting Tips

  • Use outdoor lights with a photocell unit or a timer so they will turn off during the day.
  • Use high pressure sodium or metal halide lamps for outdoor applications if color quality is not a factor.
  • Turn off decorative outdoor gas lamps; just eight gas lamps burning year round use as much natural gas as it takes to heat an average-size home during an entire winter.


Home and office lighting accounts for anywhere between 20% to 50% of electrical consumption. Making use of compact fluorescents (fluorescent lights adapted to screw into standard lamp and fixture sockets) can reduce the consumption compared to the  load of incandescent lamps by 75%. Compact fluorescents (CF’s) also help to reduce unwanted heat gain during hot summer months yet still provide equivalent lighting.

Advantages of compact fluorescent lighting:

  • A 25-watt compact fluorescent light produces as much light as a standard 100-watt incandescent.
  • Compact fluorescents have a rated life of 10,000 burn hours versus a rated life of only 750 burn hours for incandescents.
  • Compact fluorescents last between 4 to 7 years in normal household use.
  • Compact fluorescents are available for both indoor and outdoor use.
  • Compact fluorescent lamps are available in numerous styles including three-way, flood, dimmable and bug lights.

Even though it may seem cliché, the best way to conserve light energy is simply to turn off the lights when you’re not using them.
