We're expanding our #renewableenergy purchases to Europe with new 37 MW wind deal in Ireland: https://t.co/SEyoQxm1ew — Microsoft_Green (@Microsoft_Green) October 9, 2017

At least some of this energy will go to powering the data centers Microsoft has in Ireland, forming a sustainable loop. The purchase brings the company's total global direct procurement in renewable energy projects to almost 600 megawatts, Microsoft noted in a statement. But at the end of the day, sustainable -- and cheaper -- energy is entirely in the interest of the big tech corporations which are always looking for ways to make their power-sucking data centers more affordable. And, of course, obtaining cleaner energy sources might keep your company from getting slammed by Greenpeace.
