Google Turns Out the Lights for Earth Hour. Will You?

Earth Day may not be until April 22, but Google is raising awareness of Earth Hour today with their "lights out" homepage.  Google explains its move:

We believe in doing our part to help combat climate change, and found the Earth Hour initiative to be a timely, important event.  Further, we think the "lights out" ideas individual-centered nature is something that millions of people worldwide can participate in.  In short, we really like it. So we did something about it.

Cities around the world are getting involved in Earth Hour, Minneapolis included.  Tonight for an hour the skyline will be dark and non-essential city lights will be turned off.  In contrast to this MetBlog entry about Earth Hour not doing any good, I think it's an important reminder for people that making little changes will add up to a big difference.  If nothing else, it's a clear sign that "going green" is going mainstream.
