Vatican's going to install solar panels on the roofs of some buildings of the Holy See:

The roof of the Paul VI auditorium will be redone next year, with its cement panels replaced with photovoltaic cells to convert sunlight into electricity, engineer Pier Carlo Cuscianna said.

[...]

A feasibility study for the planned conversion, published recently in the Vatican newspaper L'Osservatore Romano, found it made economic sense. It quoted from Benedict's speeches defending the environment and noted that his predecessor, the late John Paul II, also championed the safeguarding of natural resources.

Cuscianna recalled a speech in which Benedict lamented "the unbalanced use of energy" in the world.

Last summer, Benedict called on Christians to unite to take "care of creation without squandering its resources and sharing them in a convivial manner." He said lifestyle choices were damaging the environment and making "the lives of poor people on Earth especially unbearable."

In other news, I love the fact that "popemobile" is an acceptable term to the AP.
