Turn off lights when not needed
An average home's lighting bill can account for up to 15% of electricity costs. Turning lights off when you're not in the room is a simple way for you to reduce your utility bill.
How it works:
Things to think about:
- 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 bulb (CFL), only a few seconds of operating power.
- Turning a CFL on and off many times per day can reduce its operating life. If you turn your CFLs on and off very often, you may need to replace them sooner. Generally, it is cost effective to turn off a CFL when you won't need it for 15 minutes or more.
- 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 unneeded or 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.
