Nationwide participation in Earth Hour reduced grid demand by 145.43 MW, showing how collective action can support energy conservation during volatile global fuel markets.

The Department of Energy commended Filipinos across the country for taking part in Earth Hour 2026, highlighting how public participation can help strengthen energy efficiency efforts.

The annual observance encourages households, businesses, and institutions to switch off non-essential lights for one hour. The initiative aims to promote long-term energy conservation habits.

During this year’s observance, the Philippines recorded a total load reduction of 145.43 MW across the national grid.

Luzon posted the largest reduction at 75.25 MW, followed by the Visayas with 66.60 MW. Mindanao recorded a 3.58 MW drop in electricity demand.

These figures show how coordinated public participation can reduce electricity consumption even within a short period.

In his message, Ferdinand R. Marcos Jr. highlighted the broader importance of the initiative.

“Earth Hour reminds us that how we use energy affects us all and reflects not only our habits, but also the kind of future we choose to build for our nation and our planet.”

The President also encouraged Filipinos to support this year’s theme, “Switch on Habits for Earth.”

He urged the public to integrate energy-saving practices into their daily routines.

“Together, let us ensure that the light of the Filipino spirit continues to shine with hope for a brighter future for all,” he added.

Energy Secretary Sharon S. Garin stressed that while Earth Hour is symbolic, its value lies in encouraging long-term behavioral change.

“Earth Hour clearly shows that when Filipinos act together, we can achieve meaningful reductions in energy demand. More importantly, it reminds us that energy conservation should not be limited to one hour, but practiced consistently in our daily lives,” Garin said.

She added that sustained energy efficiency and conservation (EEC) practices remain critical in addressing global challenges affecting fuel supply, electricity prices, and energy security.

“Simple actions, such as turning off unused lights, using energy-efficient appliances, and managing our energy consumption wisely can collectively strengthen our country’s energy resilience and help secure a more sustainable future,” she said.

The DOE reiterated its call for households and businesses to continue energy-saving practices beyond the annual observance.

The agency said consistent energy conservation can help reduce electricity costs while supporting national goals of energy security, affordability, and environmental protection.

The department also thanked stakeholders across the country for their participation and support.

Officials said sustained public cooperation will remain key to building a more energy-conscious and sustainable nation.
