When daylight saving time shifts the clock forward, most people think about lost sleep or longer evenings. But the extra daylight can also create opportunities to lower your household energy costs.

Because sunset occurs later in the evening, many homes rely less on artificial lighting and certain appliances during peak hours. Small behavioral changes during daylight saving time can add up to meaningful energy savings over the course of the year.

Below are practical ways households can use daylight saving time to reduce electricity use and potentially save hundreds on annual energy costs.

At a Glance: How Daylight Saving Time Can Reduce Energy Use

Energy habit	Why it helps	Potential impact
Using natural light longer	Less need for artificial lighting	Lower electricity use
Adjusting thermostat timing	Reduced heating or cooling demand	Lower HVAC costs
Running appliances earlier	Avoids peak electricity rates	Utility bill savings
Outdoor activities later	Reduced indoor energy use	Lower cooling and lighting costs

Lighting accounts for about 15% of electricity use in the average U.S. home, according to the U.S. Energy Information Administration. Longer daylight hours can reduce the need for artificial lighting.

1. Use Natural Light Longer in the Evening

With daylight saving time, the sun sets later in the evening. That means households can rely on natural light instead of turning on lamps and overhead lights. Opening curtains and blinds can maximize daylight indoors and reduce electricity consumption.

The U.S. Department of Energy recommends using daylight whenever possible to reduce lighting costs.

2. Adjust Thermostat Timing

Many homes run heating or cooling systems during peak evening hours. Because daylight saving time shifts daily routines, adjusting thermostat schedules can help reduce HVAC usage.

For example:

• Delay cooling slightly in the evening
• Use programmable thermostats
• Take advantage of cooler outdoor temperatures

Heating and cooling account for about half of household energy use in the U.S., according to the U.S. Department of Energy. Even small adjustments can lower utility bills.

3. Run Appliances During Daylight Hours

Daylight saving time can make it easier to run energy-heavy appliances earlier in the day. Consider using daylight hours for:

• Laundry
• Dishwashers
• Electric cooking appliances

Some utilities charge higher rates during peak evening hours. Running appliances earlier can help avoid those price spikes. Time-of-use electricity pricing is becoming more common among U.S. utilities, according to the Federal Energy Regulatory Commission.

4. Spend More Time Outdoors

Longer daylight hours encourage more outdoor activities. That can indirectly lower household energy use.

For example:

• Less TV time
• Less indoor lighting
• Reduced cooling needs

Energy savings can come simply from spending fewer hours using electricity indoors.

5. Upgrade to Energy-Efficient Lighting

If you’re taking advantage of daylight saving time to reduce lighting usage, upgrading your light bulbs can amplify the savings. LED bulbs use up to 75% less energy than incandescent lighting, according to the U.S. Department of Energy.

Combining efficient lighting with longer daylight hours can significantly reduce electricity consumption.

6. Take Advantage of Outdoor Cooling

Spring and early summer evenings often stay cooler longer. Instead of immediately running the air conditioning, households can try:

• Opening windows
• Using ceiling fans
• Letting outdoor air cool the home

The Environmental Protection Agency notes that improving airflow and ventilation can help reduce cooling costs.

7. Reset Energy Habits During the Time Change

Daylight saving time can act as a reminder to review energy habits around the house. Consider using the time change to:

• Adjust thermostat programs
• Check insulation and weather sealing
• Replace old light bulbs
• Review electricity usage on your utility account

According to the U.S. Energy Information Administration, behavioral changes can significantly influence household energy consumption.

Quick Decision Guide

Want the fastest way to lower electricity costs? Use natural daylight before turning on lights.

Trying to reduce air conditioning use? Open windows and use fans when outdoor temperatures drop.

Looking for long-term savings? Upgrade lighting and optimize thermostat schedules.

Final Take to GO

Daylight saving time doesn’t automatically reduce your electricity bill, but it creates opportunities to use natural light longer and adjust daily energy habits.

By relying more on daylight, adjusting thermostat schedules and shifting appliance use earlier in the day, households may be able to lower energy consumption and reduce utility costs.

Small changes can add up over time, especially during the months when daylight lasts longer in the evening.
