We're also giving employees in most of our offices around the world next-generation, super-efficient LED light bulbs to encourage energy efficiency. (LEDs use up to 90% less energy than incandescent bulbs and 50% less energy than a CFL.) In the average U.S. home, lighting accounts for about 20% of the electricity bill. If every Googler changes out one incandescent light bulb for one of these LEDs, the combined impact would be the equivalent of taking over 4,000 cars off the road for one year!
Of course, installing efficient light bulbs is just one way to cut down on energy consumption and costs. Just in time for Earth Day, the Climate Savers Computing Initiative's Power Down for the Planet pledge campaign aimed at colleges and universities wrapped up last week. More than 17,000 students took the pledge to support more efficient computing. The University of Maine at Farmington won the challenge, beating out 18 other schools with more than 24% of their campus community taking the pledge. You too can help save energy by enabling power management on your computer and buying more efficient computers.
As you take a moment today to think about how you can make our lovely patch of blue and green a little more healthy, we encourage you to explore a special gallery of Google Earth layers we compiled to inspire awareness and appreciation for the Earth's environment. With the power of Google Earth, we have the ability to visualize geo-spatial information and help us better understand the true impact humankind has on the planet. For example, you can visualize the changes in glaciers over the years, rising sea levels and climatic change and rising temperature from the feature KMLs in our Gallery.
Like others have said before us, we like to think that every day is Earth Day. But on this 39th anniversary of the official Earth Day, we're showing Mother Earth a little extra love and care, and hope that you'll be doing the same.
