Three cheers for the Vatican. Here's the Catholic church practicing what Pope Benedict XVI preaches about conserving energy and the moral obligation to live an eco-friendly life. The photo shows a worker for a German company attaching a solar panel to the roof of Paul VI hall at the Vatican yesterday. According to the Associated Press:

A total of 2700 panels will be placed to provide 300,000 kilowatt hours which will be used to illuminate, heat or cool the building where the pontiff holds his general audiences in the winter and in bad weather. Concerts in honor of the pontiff are also staged in the 6,300-seat audience hall. In the background St. Peter's Basilica.
