Daylight saving time transition impacts energy and policy

As the transition from daylight saving time to standard time approaches in late October, discussions regarding its impact on energy consumption and health are increasing. In Italy, data from Pulsee luce e gas indicates that standard time periods see a 24.1% increase in overall domestic energy consumption compared to daylight saving months. The most significant rises are seen in laundry services (+80.6%) and lighting/electronics (+63.7%) due to earlier darkness.

In response to these seasonal shifts, a resolution has been presented to the Italian Chamber of Deputies to advocate for making daylight saving time permanent. Proponents suggest this could save approximately 462 million kilowatt-hours annually and benefit sectors like tourism and commerce, though critics note it would result in much later sunrises during winter months.

In Greece, the time change is scheduled for the last Sunday of October. The practice, regulated by European Union Directive 2000/84/EC, aims to optimize daylight usage, though the debate over abolishing the biannual switch continues at the European level. Health experts also note that the transition can cause temporary physiological disruptions, often described as a ‘mini jet lag,’ affecting sleep and mood.
