Some Holy See buildings will start using solar energy, reflecting Pope Benedict XVI's concern about conserving the Earth's resources, a Vatican engineer said Tuesday. 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. The 6,300-seat auditorium is used for the pontiff's general audiences on Wednesdays in winter and in bad weather during the rest of the year. Concerts in honor of pontiffs are also staged in the hall, with its sweeping stage.
The cells will produce enough electricity to illuminate, heat or cool the building, Cuscianna said.
"Since the auditorium isn't used every day, the (excess) energy will feed into the network providing (the Vatican) with power, so other Vatican offices can use the energy," he 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... read more about the Vatican's Solar Power Plans
