Are you ready for Earth Hour in 2011?

Every year the Earth Hour celebration gets bigger and bolder. Which cities will be shutting off the most power this year?

From New York to Sydney, the Earth Hour shut off has become a global movement, as more and more people vie to save electricity and speak out about climate change.

In reality, there is not much that can be done to reverse the upward trend of pollution from developing nations, but richer countries can try to stem their use of power.

So whether you're are an entrepreneur using an external monitor to power a skip video convo, or a filmmaker leaving that charger in the wall for your DSLR, just remember you can save a little.

If everyone takes the same exact action lots of green house emissions can be saved. Best of luck to you this hour!
