To ensure that the green office solutions your company uses are beneficial, it’s a good idea to understand how the effects of Daylight Savings Time (DST) influences your energy use. Daylight Savings Time affects many Americans across the country, and theoretically saves a bit of energy overall because we spend less time using electrical devices at night.

But Forbes contributor Tom Zeller Jr. cites information from a 2014 study that suggests that losing the hour might not be worth it.

Although he references a 2008 study from the Department of Energy, which contends that Daylight Savings Time (DST) saves electricity, it was to the amount of one third of one percent every year, which may not be worth some of the other costs. Some places, like the state of Indiana, have actually seen an increase in energy use since adopting DST in 2006, reportedly due to an increase in heating and cooling spend that negated the electricity savings.

Because it has been around for so long, there are several myths that could be attached to DST. Rachel Feltman of the Washington Post said that there’s no real evidence that saving an hour leads to saving energy as well, despite what some people may think.

“Studies have indicated that people may use less of some kinds of energy, such as electric lights, but more of others,” she writes. “More productive daylight hours might be meant to get you off the couch and recreating outside, but they’re just as likely to lead to increased air-conditioner use if you stay home and gas guzzling if you don’t.”

With this in mind, companies need to make sure they don’t inadvertently create unnecessary energy waste for themselves on the premises. Extra energy expenditures can creep up suddenly, so business managers should work hard to consider a course of action that will help them reduce their carbon footprint.
