Earth Hour is a worldwide movement for the planet organized by the World Wide Fund for Nature (WWF). The event is held worldwide annually encouraging individuals, communities, households and businesses to turn off their non-essential lights for one hour, from 8:30 to 9:30 p.m. on the last Saturday in March, as a symbol for their commitment to the planet. It was famously started as a lights-off event in Sydney, Australia in 2007. Since then it has grown to engage more than 7000 cities and towns worldwide. Today, Earth Hour engages a massive mainstream community on a broad range of environmental issues. The one-hour event continues to remain the key driver of the now larger movement. Earth Hour 2014 was on Saturday, March 29, from 8:30 pm to 9:30 pm in a location’s local time. Earth Hour 2015 will be on Saturday, March 28, from 8:30 p.m. to 9:30 p.m. during participants’ local time.
It was started In 2004, when after confronted with scientific findings, WWF Australia met with advertising agency Leo Burnett Sydney to “discuss ideas for engaging Australians on the issue of climate change”. The idea of a large scale switch off was coined and developed in 2006, originally under the working title “The Big Flick”. WWF Australia presented their concept to Fairfax Media who, along with Sydney Lord Mayor Clover Moore, agreed to back the event. The 2007 Earth Hour was held on 31 March in Sydney, Australia at 7:30 pm, local time. In October 2007 San Francisco ran its own “Lights Out” program inspired by the Sydney Earth Hour.After their successful event in October, the organisers rallied behind Earth Hour 2008.
Since being introduced in 2008, Earth Hour has been celebrated Around the world: the Azrieli Center in Tel Aviv was darkened for Earth Hour 2010, the Colosseum in Rome was darkened for Earth Hour 2008. The Auditorio de Tenerife was also darkened for Earth Hour. According to WWF Thailand, Bangkok decreased electricity usage by 73.34 megawatts during Earth Hour which is equivalent to 41.6 tonnes of carbon Dioxide and Ontario used approximately 900 megawatt-hours less electrical energy during Earth Hour. The Golden Gate Bridge and Marin Headlands in San Francisco also turned off many public lights during Earth Hour. The Sky Tower in Auckland, New Zealand, also switched off its usual floodlighting during the Earth Hour, and re-lit afterwards. The Danish royal palaces, Amalienborg Palace and Gråsten Palace, went dark at the Queen’s command.Nelly Furtado held a free concert at Nathan Phillips Square in Downtown Toronto to celebrate Earth Hour.
Having The lights turned off During Earth Hour also presented an ideal opportunity of Astronomers to see the sky And Stargazing activities were held in Toronto’s Ontario Science Centre and Richmond Hill’s David Dunlap Observatory and Astronomy Ireland set up high-powered telescopes in Dublin’s Phoenix Park to allow people to take advantage of the night sky, normally swamped by bright city lights. Meanwhile In Tel Aviv, Israel, a free concert by Knesiyat Hasekhel was held at Rabin Square. Power needed for the concert was generated by a group of cyclists pushing pedal generators. The rest of the power was supplied by generators burning used falafel oil for power. In Atlanta, Georgia, the CEO of WWF US, Carter Roberts, and the Mayor of Atlanta, Shirley Franklin, flipped a giant switch on live TV, symbolically starting the wave of lights going out on the buildings around the city.
In San Francisco, a public event hosted by WWF US was attended by Mayor Gavin Newsom, Gold medal figure skater Brian Boitano, Grateful Dead drummer Mickey Hart, and other celebrities. They gathered to watch the lights go out, listening to the music of Jason Damato. In Kuala Lumpur, Malaysia, the lights of the world’s tallest twin towers, the Petronas Towers, were turned off, while In Egypt, the lights went out on the Sphinx and the Great Pyramids of Giza from 8:30 to 9:30 pm.
