Greenpeace released its latest report today asking, “How clean is your cloud?”
The
annual report examines the server farms built by the largest Internet
companies — including Amazon, Apple, Facebook, Google, Microsoft and
Yahoo — and ranks them according to how efficient their cloud facilities
are, and where they get their electricity.
Yahoo
— which has struggled to please investors in recent years — was the
only major Internet company in the study to get most of its electricity
from renewable or clean energy sources, according to the report.
Many
server farms can consume as much electricity as a small city. Some of
the largest consume as much electricity as 180,000 homes.
