"Amazon has been accused of operating a &amp;quot;dirty cloud&amp;quot; service by environmental group Greenpeace. A report by the non-profit organisation suggests that the online retailer only uses 15% clean energy to power its Web Services division, while fellow tech giants Apple, Facebook and Google were praised for their efforts to adopt renewable fuel sources.  Web Services is said to draw 28% of its power from coal, 27% from nuclear and 25% from gas. Amazon was also criticised for failing to publicly disclose details of its energy footprint. &amp;quot;By continuing to buy dirty energy, Amazon Web Services not only can&amp;#039;t seem to keep up with Apple, but is dragging much of the internet down with it,&amp;quot; said Greenpeace senior IT analyst Gary Cook. However, Amazon has refuted Greenpeace&amp;#039;s claims, dubbing them inaccurate and stressing that two of its data centres run off 100% carbon-free power.  &amp;quot;Greenpeace&amp;#039;s report misses the mark by using false assumptions on AWS operations and inaccurate data on AWS energy consumption,&amp;quot; said the e-commerce giant in a statement issued to BBC News. &amp;quot;Running IT infrastructure on the AWS Cloud is inherently more energy efficient than traditional computing that depends on small, inefficient, and over-provisioned data centres.&amp;quot; Greenpeace criticised Apple over its energy practices back in 2012, but the Cupertino firm has since entered the group&amp;#039;s good books for its efforts to move towards 100% renewable sources.
