8 March 2016, Energy Post, New data debunks clean energy claims Apple, Amazon, Google. Recent claims by owners of large data centers that a large part of their operations are powered by renewable energy have skeptics coming out of from under their solar panels. Now, there is hard data proving that skepticism is valid, writes energy consultant and author Jim Pierobon. He applauds the efforts of companies like Amazon, Apple and Google to strive for clean energy, but calls for more transparency on their actual practices. A recent report by Lux Research casts a large shadow on some data centers’ clean-energy claims. Scientists at Lux Research found the data centers frequently draw on far more coal-fired power with its much higher emissions than renewables. Companies such as Google, Amazon and Apple should be careful about the claims they make, lest they come across partly as PR stunts. Amazon’s claims are off-base in 23 of its data centers in Virginia. It is less than transparent about how it calculates its emissions “They aren’t doing as much as they claim about sourcing their electricity,” said Ory Zik, Lux Vice President of Analytics. Full-time Data centers need a lot of power to run 24/7. They cannot rely on the intermittent supplies that come from solar and wind energy systems. As a result, they must draw electricity from the regional power grid. Solar and wind systems they have deployed or are developing can help supply renewable power to their centers and to power grids. But they supply nowhere near enough electricity on their own to run operate data centers reliably full-time. Read More here
