Apple named 'least green' tech company


The Guardian reports: Apple has come in at the bottom of the most comprehensive green league table of technology companies because of its heavy reliance on "dirty data" centres.

The list, which is compiled by Greenpeace and released in San Francisco yesterday, shows that the company relies heavily on highly polluting coal power at the sites that house its banks of servers.

Greenpeace's report, "How Dirty is Your Data?" reveals that the company's investment in a new North Carolina facility will triple its electricity consumption, equivalent to the electricity demand of 80,000 average US homes. The facility's power will be supplied by Duke Energy, with a mix of 62% coal and 32% nuclear. On Wednesday, Apple posted a large boost in quarterly earnings, which grew by 95% to $6bn.

Gary Cook, Greenpeace's IT policy analyst and lead author of the report, said: "Consumers want to know that when they upload a video or change their Facebook status that they are not contributing to global warming or future Fukushimas."

Companies in the US are not required by law to disclose their energy use or carbon emissions. But Greenpeace drew on publicly available information on investments made in data centres, to estimate the maximum power these facilities will consume, and matched that information with data from the government or utilities.

The report estimated dependence on coal for Apple's data centres at 54.5%, followed by Facebook at 53.2%, IBM at 51.6%, HP at 49.4%, and Twitter at 42.5%. Top marks in Greenpeace's clean energy index went to Yahoo, followed by Google and Amazon. Greenpeace is also campaigning for Facebook to "unfriend coal" and use cleaner energy to power its servers.

Cook said: "Many companies treat their energy consumption a bit like the Coca-Cola secret formula, because they don't want competitors knowing how much they spend on energy. The amount of electricity they consume would give some indication of what kind of arms race they were in. They don't really want this story to be told."
