What Is Earth Hour?

Updated on April 18, 2012

Earth hour is an annual global event organised by the World Wide Fund for Nature (also known as World Wildlife Fund and WWF) on every last Saturday of the month of March.

This event is aimed at sensitising people on the effects of climate change, by encouraging them to switch off all non essential light bulbs for a one hour period.

WWF aims to protect endangered wildlife and environments, tackle climate change and promotes sustainable use of resources.

The History Of Earth Hour

The idea of the earth hour started off in Australia where WWF Australia liaised with Leo Burnett Sydney to seek a solution of climate change in Australia. This idea took a large scale dimension in 2006 after it started receiving major global attention.

Eventually this event was rolled out globally and in the year 2007 on March 31st (at exactly 7.30 pm) in the city of Sydney the event took off to the amazement of the entire world. Since then the whole idea was adopted by other major world cities and by 2008, the concept behind this event had spread out far and wide.

This year (2012), the earth hour was held between 8.30 pm and 9.30 pm due to the difference in the participating cities' local time. This event received further popularity boost from the social media platform and hence creating a bigger impact than any of the other preceding events.

In 2013, this event shall be held on the 30th day of March 2013; which will be on a Saturday.

UK Earth Hour 2012

In the United Kingdom, several renowned landmarks took part in commemorating this great event. Among them: Tower bridge, Clifton Suspension Bridge, Wembley Stadium, St Paul's Cathedral, HMS Victory and The Edinburgh Castle.

Across the UK, dance floors were lit up, street dance jubilations hit the air and the stars from The Britain's Got Talent TV show added to the moment. Efforts went a notch further in UK primary schools after the launch of the community challenge competition. This motivated the future generation to appreciate the efforts of conserving energy in order to reduce the effects of climate change.

In parliament buildings, this event was marked with a spectacular 200 guest WWF meeting held in the Great hall. The event featured a cabaret show from Cahoots NI theatre, a memorable performance from Sky 1's dance finalists Razzle dazzle and when the lights were switched off, the elite guest were taken through a torch lit WWF panda tour of the parliament buildings.

In Scotland, the celebration mainly featured school children who laid out LED Tea Lights to spell the words "Climate Action Now." This event took place at the landmark Edinburgh castle which also switched off its light in the commemoration of this event. This efforts were complemented by an outdoor theatre (Falkirk), A manual powered cinema (Kirkcaldy) and a night time wildlife walk in Syke.

      seems more like crime hour to me, almost like now it's the time for robbing houses. Don't get me wrong I love nature and that's why I think it deserves more than an hour ;)
