For one hour each year on a dark March evening, millions of people around the world turn off their lights to commemorate Earth Hour. The movement was originally created by the World Wide Fund for Nature (also known as the World Wildlife Fund in the United States). Earth Hour aims to raise awareness and support for the environment and calls on participants to 'use [their] power to change climate change.'

The first official lights-out event was held in Sydney, Australia in March 2007, followed by a similar event in San Francisco later that year. Now, Earth Hour boasts participation from more than 170 countries and territories around the world.

Earth Hour is observed on a pre-determined night every March, beginning at 8:30 p.m. during participants' local time. In addition to homes and businesses turning out lights, monuments like the Empire State Building, the London Eye ferris wheel and Red Square in Moscow also went dark.

The massive scale of Earth Hour has prompted governments around the globe to take more action against climate change. While the 60 minutes of decreased electricity usage already helps the planet, the main goal of Earth Hour is to motivate a group of people to take more steps towards protecting Earth from climate change.

Earth Hour 2016 was held on Saturday, March 19. The 2017 event will be held on March 25.
