Amazon web services is bringing on five new solar farms to help power its massive cloud data centres. The new solar facilities, all in Virginia, will bring 180 MW of power onto the grid by the 2017-end, the company announced. Those new facilities, along with Amazon´s existing plants, are expected to provide 580,000 MWh of energy annually. Four of the farms are rated at 20 MW in capacity, while the fifth is a 100 MW facility. The projects are a part of the company´s ongoing efforts to go green.
