Earth Hour is an annual event that encourages individuals, communities, and businesses to turn off non-essential lights and electrical appliances for one hour as a symbol of their commitment to the planet. It was initiated by the World Wide Fund for Nature (WWF) and first took place in Sydney, Australia, in 2007.
Earth Hour usually occurs on the last Saturday of March each year, from 8:30 p.m. to 9:30 p.m. local time. During this hour, participants are encouraged to switch off lights in their homes, offices, and other non-essential electronic devices to raise awareness about energy consumption, climate change, and environmental sustainability.
The event has grown significantly since its inception and has become a global movement, with millions of people in over 190 countries participating each year. Earth Hour aims to demonstrate that individual actions, when combined, can have a significant impact in addressing environmental challenges and promoting a more sustainable way of living.
