Does Daylight Savings Time Affect Energy Usage?

Every year, clocks are turned one hour back in the fall and one hour forward in the spring to account for Daylight Savings – Fall Back, Spring Forward! But did you know springing your clock forward an hour can actually save you energy and money on daylight spending? Our Florida Keys AC repair and service company shares insight into saving energy during Daylight Savings Time.

How Does Daylight Savings Time Save Energy?

The idea behind Daylight Savings Time was to give people more hours of sunshine after working hours so that they may enjoy more time outdoors, enjoying the fresh air. Theoretically, when we spend more time outdoors, our homes are using less energy to maintain cooler temperatures indoors since there isn’t a lot of activity inside.

Saving Energy During Daylight Savings Time

Daylight Savings Time has been around as a way to save energy. But the question remains – does Daylight Savings Time save energy? The Office of Energy Efficiency and Renewable Energy completed a study in 2008 on the impact of extended Daylight-Saving Time on national energy consumption. They found that the electrical savings on a national level of primary energy consumption resulted in a reduction of 17 trillion Btu.1

Daylight Savings Time & HVAC

Most smart HVAC systems will adjust to Daylight Savings Time automatically. This means that the heating and cooling schedule of your HVAC system will update automatically and keep your home right on track to save money during DST.

If your HVAC system doesn’t update automatically you will have to manually reset your thermostat to follow the new schedule after Daylight Savings Time has started.
