The tiles were replaced with a much greener solution — 7,244 Sharp 80 Watt solar panels to be precise. Interestingly only 4898 of these panels while the rest are dummy panels. Not only do the solar panels provide a weatherproof barrier but also provide 380-kilowatts of electricity which is enough to power 1000 PC's for a year. Additionally there are 24 wind turbines on the roof, which provide 10% of the total power used by the building."
