Turn off lights when not needed

Why? An average home's incandescent lighting bill accounts for close to 4% of electricity costs. Turning lights off when you're not in the room is a simple way for you to lower your utility bill.
How it works:

  • You save energy whenever you turn off a light, unless you plan to turn it on again immediately. Light bulbs use a little bit of extra energy to "start up" — for a compact fluorescent light (CFL) bulb, only a few seconds of operating power.
  • Turn off incandescent bulbs every time they are not needed.
  • Turning a CFL on and off many times per day can reduce its operating life. Generally, it is cost effective to turn off a CFL when you won't need it for 15 minutes or more.

Things to think about:

  • Make it a habit to turn lights off each time you leave a room.
  • Before you go to sleep, walk through your home and shut off any forgotten lights.
  • To help get into the habit, try leaving eye-catching reminders near your lights and doorways.
  • Encourage other family members to turn off their lights, as well. This is a great way for young children to do their part in saving energy.
