Vatican plans to tap solar energy
ROME - 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.
