Earth Hour
March 25, 2017 @ 8:30 pm - 9:30 pm
Earth Hour 25th March 2017, Earth Hour is an annual event, usually held on the last Saturday evening in March, when millions of people and thousands of business worldwide turn off lights and shut down most electrical appliances to celebrate sustainability and show their support for strategies that will help solve the problem of global warming.
Earth Hour was inspired by a demonstration in Sydney, Australia on March 31, 2007, when more than 2.2 million Sydney residents and more than 2,100 businesses switched off lights and non-essential electrical appliances for one hour to make a powerful statement about the leading contributor to global warming: coal-fired electricity.
That single hour accounted for a 10.2 percent reduction in energy consumption across the city. Global icons such as the Sydney Opera House went dark, weddings were held by candlelight, and the world took notice.
