Earth Hour

The following message has been forwarded around my kids school. Seemed like a cool idea:

Earth Hour is coming! The people of Phoenix have an exciting
opportunity to positively impact climate change this Saturday, March
29th. Phoenix is one of four U.S. cities selected by the World
Wildlife Fund to participate in Earth Hour 2008, a worldwide event
March 29, from 8 to 9pm. During this one hour, please join millions
of people across the world in shutting off your lights.

Turning off all non-essential lights for one hour alone can make a big
impact. Last year, Sydney, Australia initiated the event and reduced
their energy use by 10% in a single hour. This energy reduction is
equivalent to taking 48,000 vehicles off the road!

The city of Phoenix cares deeply about the negative effects of global
warming and is committed to reducing our energy use and dependence on
foreign sources of fuel. As part of our sustainability campaign, the
city has retrofitted 95% of city buildings with energy-efficient
lighting, has implemented nine solar energy projects across the city,
has worked to build one of the nation's largest municipal clean fuel
fleets, and has partnered with grocery stores to reduce the use of
plastic bags and promote reusable bags.

APS and SRP will measure how much energy is saved during Earth Hour
Phoenix. So, we need your help to make every little bit count.
Please join us in demonstrating our city's commitment to keeping our
environment clean, safe, and sustainable for generations to come. To
volunteer or to learn more, contact the Earth Hour hotline at (602)
