How to organize an event for Earth Hour (by doing more than turning off your lights)

On March 26 at 8:30 pm local time, individuals, businesses and landmarks will turn off their lights for 60 minutes in a coordinated effort to raise awareness of climate change.

The annual international event, organized by environmental group WWF, began in 2007 in Sydney, Australia; since then Earth Hour has spread across the globe. In 2010, 128 countries took part and landmarks such as Big Ben, the Eiffel Tower and the Empire State Building all dimmed their lights.
