Turn off the lights and join nearly 1 billion others in saving energy to raise awareness about energy consumption - during the fourth annual Earth Hour, March 27, 2010 at 8:30 pm - your time zone, wherever you are.It's hard to imagine that something as easy as turning off your lights could have a real impact in combating climate change, but that’s the idea behind Earth Hour, a global event sponsored by the World Wildlife Fund (WWF) designed to highlight the importance of energy conservation in the fight against global warming.
More than 1 billion participants on March 27 will help stage what has become a visually stunning event: People around the world, including whole cities and national monuments, will come together to make a bold statement about their concern for climate change by doing something quite simple—turning off their lights for one hour.
Participation is easy. By turning off the lights for an hour, starting at 8:30 p.m., on March 27, know that you are participating in a global movement that for that brief period of time, signals your commitment to combating climate change, even if it's just in your own home. If you missed Earth Hour, it's not too difficult to consciously integrate the concept into your daily life. Why not reduce the temperature in your house and put on a sweater instead? Make sure you turn off lights in rooms you're not using, and DEFINITELY unplug those unused appliances. Turning them off is not enough, especially for "transformers" - anything that has a large, black box on it, sometimes with a light. Those transformers suck about as much electricity when the appliances (computers, cell phones, etc.) they charge aren't in use as when they are. The amount of passive energy drain (or "standby loss") from unused plugged-in appliances and chargers is astounding. For example, approximately 23% of the total electricity used by a TV is from standby loss.
A study conducted by the American Council for an Energy-Efficient Economy found that leaking electricity from normal household appliances estimated for normal use across homes in the United States could light 25,984,000 homes. In addition, to really hit the point home, passive energy loss from appliances in all homes across America is responsible for more than 6 million metric tons of U.S. carbon emissions. For more specific numbers on energy loss per appliance, see this chart.
