Go an Hour Without Power: Earth Hour 2012

You’ve seen all the videos and images we’ve been featuring lately that astronauts on the International Space Station have taken of Earth from orbit. The one ubiquitous feature is the amount of lights showing up from cities and towns around the world.

But will you be turning off the lights this weekend for Earth Hour 2012?

Earth Hour is a world-wide effort to raise awareness about the need to take action on climate change. This year, Earth Hour is on Saturday, March 31 and starts at 20:30 (8:30pm) wherever you are. People all over the world — and off the planet — will be turning off non-essential lights for an hour. Even the astronauts on the Space Station will be doing their part, as well as watching from above to see if they can there is a noticeable change in the amount of lights from Earth. Astronaut and nature ambassador André Kuipers will be taking photos and videos of Earth Hour from space.

What began as a single-city initiative in Sydney, Australia – in 2007, Earth Hour has grown into a global symbol of hope and movement for change. Earth Hour 2011 was the world’s largest ever voluntary action with people, businesses and governments in 135 countries across every continent joining in the symbolic environmental event.

Organizers say as many as 1.8 billion people will participate this year. Will you be one of them?

    Those interested might like to look the YouTube Video “Is Earth Hour Dead?” interview by one of the co-founder of this quite nuts movement, the Australian advertising guru Todd Sampson. (Advertiser= someone who knows how to manipulate the masses.)

    This interview was made on 31st March 2012, so it is current and a day after this UT story.


    Note: He has changed his message (tune) somewhat since it was introduced to become as unpopular as it is now.

    If it was Earth day or week it may have some benifit but unfortunately due to the short term nature of the “Saving” most swing generators will keep up spinning resurve and not save much in fuel at all. Also large load swings cause disruption to the power supply so more spinning resurve is needed to absorb the load swing making it even less effective for reducing greenhouse emmisions.
    It may save a little if the swing producer is a Hydro dam but there are not many of those.

    Not at all. This is a cause that should be supported by everyone and everything. I support this cause.
