Much of the power that IT consumes is being wasted. Industry experts have reported that the cost of wasted server capacity is more than $100 billion per year. This paper addresses the greening IT as an incremental and continuing process that you can tackle in bite-sized pieces.

Energy costs continue to take up a significant portion IT budgets, and it seems that there is no end in sight. According to Gartner, "The underlying consumption of energy in large data centers to power and cool hardware infrastructure is likely to increase steadily during the next 10 years. This scenario is likely because of the increase in energy consumption of processors, servers, storage devices, and 1network-type appliances." Many companies are already seeing their energy costs escalate. The fol-lowing example conveys the magnitude of the problem:
A facilities executive of a global investment bank strode into the office of the CIO. He dropped an electricity bill on the CIO's desk and said, "I believe this is yours." The bill, which was the first the CIO had ever been asked to pay, was for nearly $2 million. The facilities executive added that his department is no longer able to sustain this level of charge, noting that the IT energy cost per square foot is about 17 times that of other departments.
Much of the power that IT consumes is being wasted. Industry experts have reported that the cost of wasted server capacity is more than $100 billion per year. Cost is not the only problem. Energy consumption has become a severe constraint on growth. In London, for example, there is now a moratorium on building new data centers because the city does not have the electrical capacity to support them.
