Rahul SomvanshiWhen the clock struck 8:30 PM on March 22, 2025, something incredible happened around the globe. Millions of people flipped their light switches off for 60 minutes in what became Earth Hour’s biggest year yet.
The Numbers Are In: 3 Million Hours for Our Planet
Earth Hour 2025 crushed previous records with a whopping 3 million hours dedicated to our planet by people in 118 countries. That’s double the participation of any previous year! From Auckland to Rio, people showed up big time for our shared home.
Famous spots that went dark included:
- Sydney Opera House
- Shanghai Tower
- Seoul Tower
- Kuala Lumpur Twin Towers
- Burj Khalifa
- The Colosseum
- Eiffel Tower
- London Eye
- Empire State Building
- UN Headquarters
- Niagara Falls
- Christ the Redeemer statue
The Sky Tower and Harbour Bridge in Auckland, New Zealand kicked things off as the first major landmarks to power down.
Climate Crisis + Biodiversity Loss = Earth Hour’s Dual Focus
This year’s Earth Hour zeroed in on two massive environmental challenges happening simultaneously:
- Our overheating planet: 2024 broke temperature records (again!), with ocean temps hitting unprecedented highs
- Vanishing nature: Plants and animals disappearing at alarming rates
Scientists warn we’re approaching ecological tipping points – those scary thresholds where environmental damage becomes irreversible.
What the Big Names Said
UN Secretary-General António Guterres didn’t mince words: “Earth hour is about solidarity, hope, and the power of collective action. Human-made climate calamity is here and now… Moving away from polluting fossil fuels – the leading cause of this chaos – towards renewable power holds immense promise for us all – it’s healthier, cheaper and more secure.”
Kirsten Schuijt, WWF International’s Director General, shared: “I am deeply moved by the incredible spirit of millions of people around the world who have come together for Earth Hour. This movement is a testament to the power of collective action and the hope we share for a healthier planet… In times when the world feels increasingly divided, Earth Hour reminds us that we can unite for a common cause, something greater, our shared home, the planet.”
Bangkok Governor Chadchart Sittipunt put it simply: “Every light turned off is a step towards a sustainable future.”
WWF-India’s Secretary-General and CEO Ravi Singh stressed how the Earth Hour Festival drives awareness about water conservation, climate resilience, and sustainable living.
H2O Takes Center Stage in India
WWF-India got extra creative by combining Earth Hour with World Water Day under the hashtag #BeWaterWise. Their Earth Hour Festival in New Delhi featured:
- A life-sized Ganges river dolphin sculpture (made from eco-friendly materials!)
- Sand art showcasing water conservation themes
- Live music with environmental messages
- Expert panel talks on water protection strategies
Major Delhi landmarks like India Gate, Rashtrapati Bhavan (the President’s house), and the New Parliament House all killed their lights for the hour.

Beyond Just Switching Off Lights
Earth Hour isn’t just about sitting in the dark! People around the world:
- Planted trees to capture carbon
- Cut back on energy use
- Led community clean-ups
- Shared #EarthHour challenges on social media
Research shows these collective actions actually work – electricity use drops an average of 4% during Earth Hour events.
From Berlin With Love: Community Vibes
At Berlin’s Brandenburg Gate, people gathered in the darkness to sing “What a Wonderful World” and “Imagine” – creating a powerful moment of environmental solidarity through music.
Measuring Real Impact
The 3 million hours of participation isn’t just a cool number – it reflects growing awareness that leads to lasting behavioral changes. Previous Earth Hours have shown that these moments spark ongoing shifts in how people use energy and support clean energy policies.
Water + Energy: The Hidden Connection
The #BeWaterWise campaign in India highlighted something many people miss: saving water saves energy too! The energy needed to pump, treat, and heat water is enormous. When we conserve water, we’re actually fighting climate change by reducing energy demand.
Mark Your Calendar: Earth Hour 2026
Already planning ahead? WWF has announced that Earth Hour 2026 will happen on Saturday, March 28, 2026.
From Small Beginnings to Global Movement
Earth Hour started small in 2007 in Sydney with 2.2 million participants. Now it spans 190+ countries as one of the planet’s biggest grassroots environmental actions.
The growth tells a story:
- 2007: 2.2 million people in one city
- 2025: 3 million hours of action across 118 countries
Everyday Actions With Big Impact
While switching off for an hour is symbolic, Earth Hour inspires year-round planet-friendly habits:
- Swapping to LED bulbs (they use 75% less energy!)
- Installing water-saving fixtures
- Supporting renewable energy
- Joining local conservation groups
- Speaking up for climate-smart policies
These daily choices add up to real environmental protection, exactly what scientists say we need to tackle our climate emergency.
