Earth Hour is an annual event where 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.

The First Earth Hour
* 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. * That single hour accounted for a 10.2 percent reduction in energy consumption across the city.

Earth Hour Goes Global
* In 2008, Earth Hour had become a global movement, with more than 50 million people in 35 countries and territories taking part. * Sponsored by WWF (a conservation group that aims to reduce greenhouse gas emissions from electricity generation by 5 percent annually).





The Purpose of Earth Hour
The goal, of course, is to inspire people to reduce their energy consumption every day, not by sitting in the dark for an hour each night, but by taking simple steps that can have a dramatic effect.

How to participate in earth hour:
* Switch to energy-efficient CFL or LED lights instead of traditional incandescent bulbs. * Turn off or unplug computers, televisions, cell-phone chargers, microwave ovens, and other appliances and electrical devices when they’re not in use instead of leaving them on standby. * Turn off lights when you leave a room or finish work for the day. Encourage your company to shut off lights and unused appliances when no one is working.

Benefits of Earth Hour

* People all over the world unite for a goal
* People share incredible experience
* Shows concern towards the environment issues
