History Of Earth Hour

Earth Hour

Earth Hour came into thinking in 2004. Andy Ridley, Co-Founder of Earth Hour, partnered with Leo Burnett and Fairfax Media from WWF Australia to draw attention to the rising issue of climate change.

WWF Australia approached Leo Burnett Sydney, an advertisement agency, with scientific information to help them engage Australians in climate change issues. Thus, the switching off of lights came into action in 2006 as “The Big Flick.”

The concept was still not broad and didn’t reach many people, so WWF Australia reached out to Fairfax Media and Sydney Lord Mayor Clover Moore. They presented the concept, and both parties loved it, deciding to help the event.

Then, the first official Earth Hour took place on March 31, 2007, in Sydney, Australia, where more than 2.2 million people and over 2,000 organizations participated. Following Sydney’s Earth Hour, San Francisco held its “Lights Out” program in October 2007. Earth Hour was the inspiration behind it, and so later, in March 2008, they carried it out by incorporating it into Earth Hour.

On March 29, 2008, about 35 countries and more than four hundred cities took part in support of the event, which was the introduction of the first international observance of Earth Hour. That year, many world landmarks, including the Eiffel Tower, and the Leaning Tower of Pisa, switched off their non-essential lights from 8 pm to 9 pm (local time).

Moreover, Google also decided to join in and turned their homepage dark on the day. The noteworthy fact is that after Earth Hour, the participating countries and areas noticed a significant megawatt-hour and carbon dioxide drop.

For example, Thailand and Bangkok noticed a reduction of 73.34 megawatts-hours and 41.6 tonnes of carbon dioxide only from the one-hour lights off. Moreover, Dubai saved about 100 megawatts-hours, a 2.4% reduction from the earlier hour.

The environmental event has since been growing and has spread worldwide to multiple nations. Millions of individuals take part in the event to do their part for the planet, which has led it to become the
