Energy Use From Wireless Networks Will Dwarf Data Center Use By 2015 42
angry tapir writes "New research (PDF) from an Australian university argues that increased carbon emissions from powering data centers aren't the biggest environmental threat from the growth of cloud computing. Instead, the problem is the Wi-Fi and cellular networks increasingly used to access cloud services. By 2015, the energy used to run data centers will be a 'drop in the ocean' compared to the energy used to power wireless access to services. By 2015 the energy consumption associated with 'wireless cloud' will reach 43 terawatt-hours, compared to 9.2 terawatt-hours in 2012 (an increase in carbon footprint from 6 megatons of CO_2 in 2012, up to 30 megatons of CO_2 in 2015). Data centers will comprise only 9 per cent on this increased energy consumption, compared to up to 90 per cent for wireless access."

World CO2 emissions for 2011 was estimated to be over 33 thousand million tons. I will not be losing any sleep over this tiny bit of manufactured melodrama.

Metaphor Hyperbole (Score:4, Insightful)
A factor of 5 does not justify the use of the metaphor "drop in the ocean". I wish people would reserve the use of metaphors for where they belong. "Metaphor inflation" just makes it harder to express yourself when using metaphors appropriately because nobody can trust that you mean what you say. The metaphor I would use for a factor of 5 is "dwarfs" or "pales in comparison". Drop in the ocean should be used when one is infinitesimally insignificant next to the other, which is not the case here.
