With Sydney, Australia driving the effort, Earth Hour is happening today around the globe. Conceived to draw attention to global energy consumption and to make an ever-so-small contribution to conservation, Earth Hour organizers are asking major cities in every country to dim or shut off the lights for an hour this evening.
Sydney led the way with strong support from the Lord Mayor, and even Google is is turning down the lights between 8 p.m and 9 p.m. to participate. And well they should, as data factories now use as much energy as all air traffic. That's right, each Google search query according to this article in Der Spiegel takes as much energy as running a low wattage light bulb for 15 minutes to an hour. Check out the Wikipedia page on Earth Hour to see if your city or town is on the partner's list. And if you can drag yourself away from March Madness or your regular evening activity for an hour, please consider participating in this grassroots, global effort. Polls have shown that the effort itself is succeeding in raising the visibility of this important issue.
