With roughly three months left before clocks revert to standard time, the push to lock in daylight saving time year-round is gaining momentum, including from the Oval Office. President Trump on Tuesday reiterated his support for making daylight saving time permanent, asserting that "the vast Majority of Americans have asked to make Daylight Saving Time permanent, but no Administration has been able to get it done, until now."
The House passed the Sunshine Protection Act last month, and the bill now heads to the Senate, where its fate is uncertain. Senate efforts to fast-track the legislation in October were blocked, leaving the measure in limbo as the November clock change approaches.
Proponents argue that permanent daylight saving time would reduce energy consumption by extending evening daylight, reducing the need for artificial lighting. However, research on this claim is mixed. A 2008 study by the U.S. Department of Energy found that extending daylight saving time by four weeks saved about 0.5% of electricity per day, but other analyses, including a 2016 study by the National Bureau of Economic Research, found minimal or no energy savings in some regions, particularly in the South where air conditioning use offsets gains.
Critics also point to potential downsides, such as darker winter mornings, which could increase risks for commuters and schoolchildren. A recent analysis highlighted that permanent daylight saving time would push winter sunrises after 8 a.m. in many U.S. cities, raising safety and health concerns.
Senate Majority Leader Chuck Schumer has not committed to a timeline for the vote, and several senators have expressed reservations. The bill's sponsors, including Senator Marco Rubio, argue that the change would benefit the economy and public health, citing studies that suggest reduced crime and improved mental well-being from more evening sunlight.
Energy policy experts, however, caution that the savings may be overstated. A 2014 study in the journal Energy Economics found that while lighting demand decreases, heating and cooling needs can rise, offsetting any net benefit. The efficiency, not just supply, is key to true energy abundance, as some analysts note, suggesting that structural changes in energy use matter more than clock shifts.
President Trump's renewed push comes amid broader energy debates, with his energy price vows unraveling as gas and electric costs surge. The administration has tied the daylight saving time proposal to its goal of lowering costs, but the evidence remains thin.
If the Senate passes the bill, it would go to the White House for signature. But with only a few months left before the fall time change, the window for action is narrow. Advocates on both sides are mobilizing, with some groups pushing for permanent standard time instead, which would keep mornings brighter but afternoons darker.
The outcome remains uncertain, but the debate highlights how a seemingly mundane issue can become a flashpoint for broader political and policy battles. As the Senate prepares to deliberate, the question of whether permanent daylight saving time actually saves energy may be central to the decision.
