How to Save On Energy Costs By Turning Off Lights in Unused Rooms

Turning off lights in unused rooms is one of the easiest ways to reduce your energy costs and save money on your electricity bill. With some simple habit changes, you can make a big difference without sacrificing comfort or convenience.

Why Turn Off Lights?

Lighting accounts for about 12% of an average home’s electricity use, so it offers significant potential for savings. Here are some key reasons to turn off lights when not needed:

  • Saves electricity. Turning lights off when leaving a room can reduce your lighting electricity use by 45% or more. This directly lowers your utility bills.

  • Reduces energy waste. Keeping lights on in an empty room is wasted energy. Turning them off eliminates this unnecessary electricity consumption.

  • More efficient lightbulbs. LED and CFL bulbs use less energy than traditional incandescents. Turning them off extends their lifespan.

  • Lower carbon footprint. Much of our electricity comes from fossil fuels. Reducing usage decreases associated greenhouse gas emissions.

  • Simple and effective. It takes just a moment to turn off a light. This easy habit change has an outsized impact.

How Much Can You Save?

The amount you can save on your electricity bill by turning off lights depends on several factors:

  • Number and type of lightbulbs in your home
  • Your electricity rate per kilowatt-hour (kWh)
  • Your usage habits and patterns

As an example, if you replace all inefficient 100-watt incandescent bulbs with efficient 10-watt LEDs, have an electricity rate of $0.12/kWh, and turn off just one bulb for 6 hours per day, you would save about $10 per year. The savings add up quickly, especially when multiple lights are turned off consistently.

What Rooms Should You Focus On?

The most impactful rooms to turn off lights are those that are unused for large portions of the day. Prime targets include:

  • Bedrooms – When not sleeping or getting ready
  • Home office – When not working in it
  • Bathrooms – When not in use
  • Storage spaces – Quick on/off when retrieving items

It takes minimal effort to turn off lights in these spaces when leaving, but it yields continuous savings. Be vigilant about turning off lights whenever exiting a room after more than 5-10 minutes of being unused.

Helpful Tips and Strategies

Here are some useful tips to build the habit of turning off lights in unused rooms:

  • Post reminders. Put up signs, stickers, or notes to remind yourself to turn off lights.

  • Automate it. Use smart lightbulbs that can be automated or controlled remotely.

  • Check at bedtime. Make an evening lap to double-check that unused lights are off.

  • Involve family. Get kids or other household members in the habit too.

  • Set an example. Turn off lights yourself first to demonstrate the habit.

  • Link it to other actions. Turning off lights when leaving a room can be paired with locking the door, for example.

Overcoming Obstacles and Challenges

Changing habits takes concerted effort, but these strategies can help overcome common obstacles:

  • If you forget to turn off lights, use cues like alarms or reminders.

  • If you occupy rooms sporadically, use smart plugs or timers for more automation.

  • If you have low motivation, track savings and set goals to stay focused.

  • If other household members don’t participate, lead by example and share results.

The modest effort to turn off unused lights pays continuous dividends on your electricity bill and your environmental footprint. Develop the habit consistently in high-traffic rooms first, then expand room by room. Consistency and concerted effort lead to easy energy and cost savings.
