Please participate by turning out lights, Saturday, March 28 at 8:30 for one hour

They say nothing about turning off all electrical appliances for the hour, just the lights. I know what it means but will everyone?

Now is the time to send a message to all the world on how dedicated we are to protecting our home - Mother Earth.
All over the world, residents, companies and governments are turning out their lights to highlight the threat of climate change.
For 1 hour on Saturday, March 28th, 2009 - starting at 8:30 pm the world will turn out the lights
Watch the planet go dark one time zone at a time as satellite pictures capture the beauty of darkness and energy conservation across the globe.
Beginning in 2007 - Sydney turned off the lights.
That single event in Australia cut 10% of their energy usage.
in 2008 the word had spread so that over 277 cities had turned off the lights.
Now in 2009 we have millions signed up to turn off their lights and over 538 cities in 78 countries.
Join us by getting your city to publicize the event on their local news. Spread the news with fliers you can download straight from the site to hang at universities, coffee shops, stores and more.
Even Google is joining the event by turning its background black each year for Earth hour
