    NYT acusa datacenters de desperdiçarem energia e serem poluidores

    Com chamada na primeira página, a extensa matéria do New York Times denuncia que o desperdicio de energia alcança 90% em algumas instalações, criticando ainda a poluição atmosférica causada pelos geradores a diesel que suportam as operações.


    A yearlong examination by The New York Times has revealed that this foundation of the information industry is sharply at odds with its image of sleek efficiency and environmental friendliness.

    Most data centers, by design, consume vast amounts of energy in an incongruously wasteful manner, interviews and documents show. Online companies typically run their facilities at maximum capacity around the clock, whatever the demand. As a result, data centers can waste 90 percent or more of the electricity they pull off the grid, The Times found.
    To guard against a power failure, they further rely on banks of generators that emit diesel exhaust. The pollution from data centers has increasingly been cited by the authorities for violating clean air regulations, documents show.

    ...

    At least a dozen major data centers have been cited for violations of air quality regulations in Virginia and Illinois alone, according to state records. Amazon was cited with more than 24 violations over a three-year period in Northern Virginia, including running some of its generators without a basic environmental permit.

    ...

    Servers are not the only components in data centers that consume energy. Industrial cooling systems, circuitry to keep backup batteries charged and simple dissipation in the extensive wiring all consume their share.

    In a typical data center, those losses combined with low utilization can mean that the energy wasted is as much as 30 times the amount of electricity used to carry out the basic purpose of the data center.
