Details weren’t released, but the Vatican will be exempt from paying Italian taxes to import the solar panels, but won’t benefit from the financial incentives that Italians enjoy when they go solar. Vatican officials have estimated it will cost under 100 million euros ($114 million) to develop the solar farm, and that once it is approved by the Italian parliament, the contracts to do the work could be put up for bids. The Santa Maria Galeria site has long been the source of controversy because of electromagnetic waves emitted by Vatican Radio towers located there since the 1950s. Pope Francis last year asked the Vatican to study developing the area into a vast solar farm, hoping to put into practice his preaching about the need to transition away from fossil fuels and find clean, carbon-neutral energy sources. In the 1990s at the height of the controversy over the radio towers, residents sued Vatican Radio officials, claiming the emissions exceeded the Italian legal limit, but the court cleared the transmitter.
