The Vatican went green Monday as workers began to install 2,700 solar panels on the roof of the Vatican's Papal audience hall.
Each of the panels has cells that convert sunlight into electricity. Workers said the panels will provide 300,000 kilowatt hours which will be used to light, heat or cool the building which is used for the Pope's general audience during the winter months.
"With this plant, if it is working in about two weeks, we avoid 210 tons of carbon dioxide. This is the equivalent to 70 tons of oil," said Vatican Site Manager Andrew Koekenhoff.
