fortune: Amazon has been building out wind generation capacity in part to power the servers hosting Amazon Web Services. by David Z. Morris
'The unit has a long-term commitment to power 100% of its services through renewable energy, and according to the company, 40% of AWS’ power will come from renewable sources by the end of 2016. Amazon’s renewable energy installations also include wind farms in Indiana, North Carolina, and Ohio, and a solar farm in Virginia.
'But critics have pointed out the AWS roadmap is not as detailed as it could be, and it’s in a renewables race with other tech giants.
'Google is also aiming for 100% renewable sources, and has said it is the largest non-utility purchaser of renewable energy in the world. Apple claims that in 2015, 93% of its energy came from renewable sources, and its data centers are already 100% run on renewables (though that claim does rely on carbon trading).'
