The Philippines recorded a total power demand reduction of 145.43 megawatts during Earth Hour 2026, the Department of Energy said Sunday, citing strong public participation nationwide.
Luzon posted the largest drop at 75.25 MW, followed by the Visayas with 66.60 MW and Mindanao with 3.58 MW, based on DOE data. The agency said the reduction reflects the impact of collective action in lowering electricity use, even for a limited period.
Energy Secretary Sharon Garin said the event’s value goes beyond the one-hour switch-off, stressing the need for sustained conservation. “Earth Hour clearly shows that when Filipinos act together, we can achieve meaningful reductions in energy demand,” she said, adding that energy-saving practices must be adopted daily.
The DOE urged households and businesses to continue measures such as turning off unused lights and using energy-efficient appliances, noting that sustained conservation can help lower electricity costs and strengthen energy security amid global supply pressures.
