Does Daylight Saving Time Save Energy?

Does daylight saving time conserve energy?

As daylight saving time (DST) ends on November 3rd, many wonder if this tradition is still beneficial in 2024. DST was originally believed to save electricity due to increased daylight hours. However, data from the Energy Information Administration (EIA) found that lighting only accounts for roughly 5% of residential electricity usage. This data challenges the original assertion that DST leads to significant energy savings.

The Standard Time Act established daylight saving time in 1918. However, electricity did not exist in all homes then and was only used for artificial lighting. In 2024, electricity is far more complex than in 1918. Although DST has minimal energy-saving benefits, many still debate the topic. Let’s explore both sides of the debate to learn if it offers any energy-saving benefits today.

Pros of daylight saving time

• Longer summer days. Many people enjoy late summer sunsets. The extended daylight hours extend time outside, especially for those who work during the day.
• Economic benefits. Increased daylight hours mean businesses benefit from more people outside the house and participating in activities.
• Active lifestyle. The additional hour of daylight encourages more people to get outside and exercise compared to nighttime when many people stay inside.

Cons of daylight saving time

• Lack of significant energy savings. Energy consumption is more evolved than when the concept was first introduced. The average household has multiple devices running around the clock regardless of daylight, decreasing the impact of one extra hour.
• Routine disturbance. Many find it challenging to adapt to the change in routine. Parents are especially concerned about the impact on children’s schedules.
• Health risks. Sleep experts, such as Adam Spira, PhD, are critical of the practice, citing multiple health risks, such as mood disturbances, sleep problems, and increased motor accidents.
• Conflicting data. Many studies have been conducted over the years to try to measure the impacts of DST. However, these studies often produce contradictory findings. Location, lifestyle, and regional differences are a few variables that make studying DST challenging.

Daylight saving time in 2024

Considering the complications with national studies, it’s hard to find a conclusive answer about exactly how much energy is conserved during daylight saving time. As of 2024, the practice remains in most U.S. states. However, the list of those pledging to end the practice, if allowed by Congress, is increasing. Some states support establishing daylight saving time year-round, while others want to establish standard time. Despite the differences among these states, all agree it would be better to stop switching the clocks twice a year.
