Manila, Philippines – In solidarity with the global observance of Earth Hour 2025 on 22 March 2025, the Department of Energy (DOE) reminds the public to adopt responsible energy and water conservation practices. With the theme “Switch Off and Secure Water for All,” this year’s Earth Hour highlights the vital connection between energy conservation and water security, emphasizing the need for sustainable practices to protect these essential resources for future generations.
Energy Secretary Raphael P.M. Lotilla underscored the interdependence of energy and water, stressing that every kilowatt-hour of electricity consumed requires water --- whether for cooling processes in thermal power plants, hydropower systems, or the energy needed to pump, treat, and distribute water.
"Using energy judiciously is not just about reducing consumption --- it is about preserving life itself. Every watt saved is a drop of water protected, reinforcing the delicate balance of our environment. By embracing energy efficiency and conservation, we do more than cutting emissions, we secure the future of our most vital resources for generations to come," Secretary Lotilla said.
Earth Hour is more than a symbolic event --- it is a global movement for change. “Through small but consistent actions, individuals, businesses, and communities can make a lasting impact on energy and water conservation, strengthening climate resilience and promoting a more sustainable way of life,” the Secretary added.
The Department of Energy (DOE) has been consistently encouraging the public to adopt practical and effective demand-side management strategies without compromising productivity. These include switching off non-essential lights and appliances when not in use, using energy-efficient technologies such as LED bulbs and inverter appliances and rescheduling high-energy-consuming activities during peak hours, which are typically from 11:00 AM to 3:00 PM on weekdays and 6:00 PM to 9:00 PM on weekends.
On 22 March 2025, from 8:30 PM to 9:30 PM, Secretary Lotilla urges the public to come together and take part in this global movement. By switching off non-essential lights, committing to energy and water conservation, and engaging in meaningful actions --- such as reducing water waste, planting trees, or supporting sustainable policies --- everyone can contribute to a more sustainable future.
The government remains committed to building a more sustainable and resilient energy system, recognizing its critical role in ensuring the country’s energy security and advancing climate action. Through progressive policies, strategic programs, and innovative measures, the DOE continues to drive energy efficiency, conservation, and the integration of renewable energy into the country’s power landscape. These efforts not only support the transition to a low-carbon economy but also foster greater public awareness of the urgent need to address environmental challenges.
As an active partner of WWF Philippines in the annual observance of Earth Hour, the DOE reaffirms the shared responsibility of individuals, communities, and institutions in mitigating climate change and promoting environmental sustainability. ###
