Ten Things to Know about Earth Hour
  1. Earth Hour 2012 takes place on March 31, 2012 at 8:30 pm—local time.
  2. The date was set in March because it is close to the Spring Equinox, a period when the most number of countries around the world will experience darkness around 8:30 p.m.
  3. Earth Hour isn't about how much energy is saved during one hour. The idea behind Earth Hour is that by working together, each one of us can make a difference on the issue of climate change. By doing something as simple as turning off the lights, we send a visual symbol to the world's leaders that we are counting on them to work together to find solutions to climate change.
  4. Earth Hour is a non-partisan event. When it comes to caring about the future of our planet, we all have a stake as citizens of the world regardless of other political beliefs and affiliations.
  5. Earth Hour turns off non-essential lighting and electronics only. Lights necessary for public safety will not go out. Nonessential lighting has been turned out safely, without any events in more than 1,000 cities worldwide.
  6. Earth Hour is nonexclusive, and everyone is encouraged to participate.
  7. WWF has designated a limited number of “flagship cities” in the US where it will devote resources to make sure the lights actually do go out. In 2009 those cities include: Atlanta, Chicago, Las Vegas, Los Angeles, Miami, Nashville, New York and San Francisco. In addition, WWF will be seeking the support of Washington DC and the federal government.
  8. Many US cities will also participate as “supporting cities.” To become an official supporting city, a proclamation or some type of official confirmation that the event is supported by the local governing body of that community must be sent to WWF.
  9. Carmel, Indiana has participated in Earth Hour 2009, 2010 and 2011 along with over 4,000 towns and cities across the globe.
  10. World Wildlife Fund is the organization behind Earth Hour, but many other groups and NGOs are also supporting Earth Hour.
