ABSTRACT
By understanding fundamentals and background information about electricity usage as well as options and alternatives including rebates or incentives, IT data centers can deploy strategies to become more energy-efficient without degrading service delivery. Reducing carbon footprint is a popular and trendy topic, but addressing energy efficiency-that is, doing more work with less energy-addresses both environmental and business economic issues. The importance of this chapter is that near-term economic as well as environmental gains can be realized by making more efficient use of energy. By reducing energy consumption or shifting to a more energyefficient IT model, businesses can reduce their operating expenses and enable more useful work to be done per dollar spent while improving service delivery. This chapter looks at challenges with electrical power for IT data centers as well as background information to help formulate effective strategies to become energy-efficient.
