When the Clocks Change, Your Energy Use May Change Too

Daylight saving time ends every fall, and most of us gain an extra hour when we set our clocks back. While the time change may seem minor, it can influence daily routines and household energy use.

As daylight hours get shorter and temperatures cool, lights are turned on earlier, heating systems begin running more often, and many households spend more time indoors. These changes can influence overall energy demand and make fall an important time to think about your energy use.

Here’s a closer look at what changes and how you can prepare for the season ahead.

How Daylight-Saving Time Changes Energy Use

The end of daylight-saving time doesn’t change how much energy your home uses overnight, but it can affect when and how energy is used throughout the day.

With sunset arriving earlier, many households begin using lights, televisions, computers, and other electronics sooner in the evening. At the same time, cooler temperatures often mean heating systems start running more frequently.

Together, these changes can create a new seasonal energy-use pattern. Common shifts include:

• Turning on lights earlier in the evening
• Using heating systems more often as temperatures drop
• Spending more time indoors after dark
• Using electronics and appliances earlier in the evening
• Using more hot water as colder weather arrives

While each of these changes seem small on its own, they can add up over the course of a season.

Why Usage Patterns Matter

Energy demand rises and falls throughout the year based on factors like weather, daylight hours, and how people use electricity. When many homes are using electricity at the same time, overall demand increases.

Seasonal transitions often contribute to these shifts. In the summer, air conditioning drives higher electricity use. In the winter, heating, lighting, and indoor activities become larger contributors.

Understanding your household’s seasonal energy use patterns can help you identify what drives consumption and prepare for periods of higher energy demand.

Why Seasonal Energy Planning Matters

It’s easy to think about energy efficiency during the hottest and coldest months of the year, but the transition seasons can be just as important.

Fall is a good time to prepare your home before winter arrives. A few things to consider include:

• Is your heating system ready for winter?
• Are windows and doors properly sealed?
• Are there opportunities to improve lighting efficiency?
• Have your energy-use habits changed since last season?
• Are there areas of your home that feel drafty?

Evaluating your home and habits can help you identify opportunities to reduce wasted energy and improve comfort as temperatures drop.

A Seasonal Energy Check-In

The time change can be a useful reminder to review your household’s energy habits. As evenings get darker earlier and more activities move indoors, your fall routine may look different than it did during the summer.

A few ways to refresh your routine include:

• Review your household schedule: Are you cooking more meals at home, spending more evenings indoors, or using electronics earlier? Recognizing these changes can help you better understand what may be driving your energy use.
• Update seasonal settings: Review thermostat schedules, outdoor lighting timers, and smart home settings to make sure they still align with your daily routine.
• Prepare for holiday activities: Decorating, entertaining, and preparing larger meals can change how you use energy. Thinking ahead can help you anticipate those changes.
• Look ahead to winter: Consider how colder temperatures and more time indoors may affect your household’s energy needs in the months ahead.

The goal is to recognize how your habits change with the seasons so you can make more informed decisions about your energy use.

Make the Most of the Seasonal Transition

Daylight saving time signals the beginning of new routines, cooler temperatures, and shifting energy-use patterns. By understanding how your household’s energy needs change throughout the season, you can make informed decisions about comfort, efficiency, and energy use all winter long.

As your seasonal energy needs change, having more predictability can help you plan ahead. A fixed-rate electricity supply plan provides stability by locking in your supply rate for the length of your contract. Explore AEP Energy’s rates and plans to find an option that’s right for your home.
