The city of London has covered the roof of its Blackfriar's Bridge (part of the Blackfriar's Railway Station) with 4,400 photovoltaic solar panels. The new solar array will have the capacity to convert enough solar energy to make 80,000 cups of tea a day. Since the energy created is entirely carbon free, the photovoltaic cells will reduce the station's carbon footprint by 511 tons, or an average of 89,000 car trips per year.
Solar arrays usually appear on the rooftops of buildings, or as part of large solar farms outside of cities–which makes the Blackfriar's Bridge all the more impressive. The project marks an ambitious effort to convert rail infrastructure—which itself consumes a sizable about of energy each year—to help solve the complex climate puzzle.
